Replace wire with synthetic alternatives that save time and operational costs while increasing levels of handling crew safety and efficiency Traditionally marine engineering has looked to wire rope for many applications.

Unfortunately, these extremely heavy strength members limit effective usage and greatly reduce safety due to significant handling problems.

Over the last thirty years, Samson has led the development of high modulus synthetic fiber ropes designed to replace wire in critical marine applications. In fact, Samson AmSteel®-Blue 12-strand braided Dyneema® mooring lines were first to market in the early 1980s. Samson high performance synthetics have proven reliability while significantly reducing the cost of operations in towing, mooring, and offshore operations.

Cost savings are realized in numerous areas; reduction in crew requirements, increase in safety for both crew and equipment, and reduction in maintenance costs due to relubing and end-for-ending. Best of all, Samson synthetics significantly outlasts wire in most applications. For some applications, like deepwater exploration and production in the offshore industry, they are an enabling technology that makes working at extreme depths a reality.

Samson Research & Development


CMCOMMERCIAL MARINE

BUILT TO MEET REAL WORLD CHALLENGES

Since its inception in 1878, Samson has been committed to technological leadership in the design and manufacturing of innovative cordage products. Using the highest performance synthetic fibers in unique constructions, Samson engineers have constantly reinvented cordage technology. We continue to expand our technology, working closely with industry to identify new applications and with suppliers to explore new fibers and materials. Samson then develops specialized constructions and coatings to maximize effectiveness, increase service life, and make the workplace safer and more efficient.

Samson R&D: The link between technology and practical application The key to all these developments is Samson’s continuous

commitment to research and development. Today, Samson’s R&D organization is the most advanced and best equipped in the industry. Headed by Dr. Rafael Chou, the R&D team is comprised of chemical and mechanical engineers, polymer scientists, nanotechnologists, material science specialists, chemists, rope designers and industrial engineers. They are all backed up with testing, quality control and splicing specialists. They are equipped with the latest technology, including the most advanced synthetic rope tensile tester in the world, capable of testing break strengths up to 1.1 million pounds.

The results speak for themselves… All this technology results in the development of products that make

real differences onboard. Recent new product introductions include patented products like reduced recoil ropes and high strength marine ropes using DPX® fiber technology. Reduced recoil ropes are designed to fail in stages, dissipating the energy of the parting line and reducing the dangerous snap back of the parted ends, making work sites safer. Samson's patented use of DPX® fiber gives our high performance ropes better grip on deck hardware like capstans and H-bitts. That means, among other applications, tug operators using H-bitts can now take full advantage of the easy handling, lightweight, ultra high strength tug lines made with Dyneema®.

Samson high performance synthetic mooring lines are the proven alternative to wire rope

Mooring Applications HIGH PERFORMANCE MOORING LINES


Lightweight, ultra-strong mooring lines reduce operating costs, save time in mooring operations, and improve safety

When compared to wire rope, Samson mooring lines made with Dyneema® are, size for size, just as strong or stronger. The comparison ends there. Weighing in at less than 1/7th the weight of wire, Samson ropes reduce crew requirements for each mooring station and have been proven to reduce the time required for mooring operations by 2/3. Lower incidents of work-related back injuries have been documented. With no fishhooks from broken strands, and dramatically reduced recoil, crew safety is further enhanced. Add in a longer service life of 4 to 10 years with greatly reduced maintenance, and any comparison to wire is pretty much eliminated. All this has been proven in actual field trials over the past 10 years.

Jacketed, non-jacketed, 12-strand or 8; there’s a Samson high performance line engineered for every mooring application and any equipment configuration…

Samson has designed a full range of mooring lines with the option of either jacketed or non-jacketed configurations; from AmSteel®-Blue, a 12-strand single braid made with 100% Dyneema®, the strongest mooring line available, to Turbo-EPX, a Dyneema® core/polyester cover construction for enhanced abrasion and heat resistance and great handling on mooring winches.

Each is engineered to provide the highest strength, longest service life and safest handling by the company with the most experience with high performance fibers in the cordage industry.

While technology and engineering are critical, it’s our service that really makes a difference

Samson doesn’t stop at merely creating a better product; we pride ourselves on providing the best service in the business – both before and after the sale. Our sales and application engineers come onboard to assess your situation and handling equipment, make recommendations on appropriate products, and assist with installation to ensure your mooring lines will perform as expected. We follow up with full training in maintenance, splicing, and inspection for your crew. In addition, we develop an ongoing program of testing and inspections to determine a customized retirement schedule to make certain your mooring lines are always safe and well maintained. It is this level of service that is at the heart of The Samson Advantage.

Samson suggests the use of braided Mooring Master P-7 (100% polyester) for primary mooring line pendants. The efficient design of P-7 pendants allows significant size and weight advantages over conventional 8-braid pendants; higher strengths can allow “down-sizing.” P-7 mooring pendants meet the recommendations of OCIMF.

P-7 mooring pendants provide the energy absorption to minimize ship excursion in a mooring system, while holding up to the abuse of being dragged on piers and working on rough mooring hooks, cleats and bollards. P-7 has braided polyester strength members covered by a heavy-duty polyester jacket. The core provides the superior flex-fatigue resistance for maximum service life, while the polyester jacket provides the protection necessary in rough working environments. P-7 pendants are available in single leg and strop configurations and can be connected to the primary mooring line by cow-hitching the soft eyes or with a mandel shackle.

P-7 Mooring Pendants Product Code: 709Mooring Master P-7

P-7 Single Leg PendantsStandard length is 11m (over all length), with a 2m soft eye one end and a 1m soft eye the other end. The vertex and splice area are urethane coated for added wear protection.

Tenex-TEC is a 12-strand Samthane coated, high tenacity polyester single braid that offers high strength, low stretch and outstanding abrasion resistance. Tenex-TEC makes an excellent mooring line stopper because, during its initial use, the design will flex-conform to the specific mooring line rope construction and improve its holding capability. As Tenex-TEC wears, its coefficient of friction increases even more. It should only be used with synthetic fiber secondary mooring lines, or mooring lines not on winches. Tenex-TEC should not be used on high performance synthetic ropes that have external outer fibers with a low coefficient of friction material such as Dyneema®.

Samson high performance synthetic ropes have been engineered to provide ease of handling, extreme strength, and long service life. Dyneema®, a major component in many of Samson’s high performance ropes, is the most cut resistant fiber. While properly designed and engineered ropes take maximum advantage of this resistance, in the real world environment of the commercial marine industry, protecting ropes from abrasion and cutting significantly increases service life.

Chafe protection engineered to combat cutting and abrasion Samson has committed substantial research and development resources to designing a line of chafe protection products that maximizes the service life of our ropes. The result is a family of products perfectly suited to combat the causes of cutting and abrasion encountered in offshore, mooring and tug operations. Because each application has its own characteristic requirements, Samson has developed a full range of options to protect your investment and ensure the longest service life for your working ropes. All chafe options can be factory-installed on your ropes prior to shipment from our plants, or are available in bulk for field installation.

When replacing wire ropes with synthetics, it is important to prepare or repair the surfaces of deck equipment damaged by abrasion. Chocks, fairleads, bollards, bitts or other hardware contacting the rope need to be smooth and free of rust to ensure your ropes’ longest life. A Samson representative is available to visit your vessel to assess the hardware condition and advise on proper preparation to maximize the service life of your ropes. That’s The Samson Advantage: high performance, reliable products, innovative engineering and the best customer service in the industry.

Few environments challenge rope as much as modern tug operations…

Tug Applications HIGH PERFORMANCE TUG WORKING LINES

SAMSON’S DPX® FIBER TECHNOLOGY:Inherently cut and chemical resistant, industry leading 12-strand braids such as AmSteel ®-Blue typically have a very low coefficient of friction (COF), limiting their use in applications that require the use of capstans or bitts. The engineers in Samson’s R&D department developed an entirely new method of combining the high heat resistance and higher COF of polyester with the high strength, lightweight, and high cut and abrasion resistance of Dyneema®. Samson’s patented use of DPX® fiber greatly increases the coefficient of friction to provide the grip of polyester with the ultimate strength of Dyneema®.

DPX® fiber technology is used in popular winch-based marine ropes like Quantum-8 and in the 12-strand construction of Quantum-12. DPX®-75 incorporates DPX® fiber technology in the cover of a jacketed product. Tug operators using H-bitts and capstans can now take full advantage of the strength and ease of handling of ropes made with Dyneema®.


Samson’s high performance synthetics stand up to the challenge

There are very few ropes in the commercial marine environment that are used with the frequency of a tugs working lines. Add to this the physical stress and abrasion that’s produced by the very nature of their work, and you’ve got one of the most demanding situations a rope can face.

Samson has designed a family of ropes that face up to these demands day in and day out. Lightweight, high strength Samson synthetic ropes engineered with Dyneema® fiber meet these tough demands for some of the world’s most critical tug operators.

Samson high performance synthetics are a safer and more cost-effective option

Lightweight, high strength Samson ropes are a safer and more cost-effective alternative to either heavy, large diameter traditional working lines or wire rope. Lightweight, easy handling lines mean reduced crew demands and fewer work-related injuries. There are no fishhooks to worry about, and once your deck equipment is faired, maintenance is minimal. Easier handling also means faster tie-ups, and the ability to stand down even quicker. The overall effect is reduced costs and more efficient operations. It has been proven in actual field tests for over 10 years.

Whether you work from a winch or H-bitts, there’s a Samson rope made specifically for your application

Samson’s patented use of DPX® fiber incorporates the strength of Dyneema® with the high coefficient of friction that polyester fiber provides. We’ve put that technology to work in two patented constructions – Quantum-8 and Quantum-12 – designed specifically for the needs of working tugs using H-bitts. The enhanced grip allows these high performance lines to work as efficiently as polyester where capstans and H-bitts are in use, but also function equally well from winches.

And, of course, they all come standard with The Samson Advantage…

The latest in fiber technology, high performance products, state-of-the-art manufacturing, and over 125 years of experience all add up to real value for our customers. When you combine these with our world-class service – experienced sales and application engineers that help solve real world problems with unique cordage products – you see why we call it The Samson Advantage.

Q-8QUANTUM-8 CASE STUDY

We talk a lot about our application and sales engineers. It is one of the things that

sets Samson apart from other manufacturers of cordage products. This is a real world

example of application engineering at its best.

Canadian Steamship Lines (CSL) Asia has been operating a Semi Submersible

Trans-shipment Platform (SSTP) for the past seven years at Muara Pantai in Tanjung

Redeb, Berau, Indonesia. The platform is stationed 10 miles offshore, and receives

barges from the mine operation, offloading the coal to the waiting capesize vessels. The

6,000MT to 10,000MT barges are ranged over a 60 meter span within the docking space

of the SSTP via four 40MT winches located at each corner of the platform. Each time

a barge is offloaded, another barge is docked and ranged until the bulk carrier is fully

loaded. The SSTP then moves via its own power to another bulk carrier awaiting loading.

With three to four barges docked and ranged daily, the ropes used in this operation are

subjected to very high fatigue stresses. Over the past five years, they had tried various

types of synthetic ropes, yet the longest period before failure was between 200 and 300

hours of operation.

A meeting between John Morton, Samson sales manager and Mr. Armindo Gomes,

technical director for CSL (Asia) resulted in a test of Quantum-8, Samson’s patented

8-strand construction using DPX® technology – a blend of Dyneema® fibers and spun

polyester fiber that provides high strength, lightweight and excellent grip for use on

winches, capstans and bitts. Favorable test results made the decision to purchase

Quantum-8 an easy one.

John Morton oversaw the installation of the ropes and trained the crew in use,

maintenance, inspection and splicing. Over the last two years of operation, Quantum-8

has been in service for 2,500 to 3,000 hours. The reduced diameter compared to the

ropes previously in use means quicker, safer mooring/unmooring operations. With barges

being docked and cargo trans-shipped at a rate of three to four a day, the increase in

productivity has been dramatic.

“…the offer of your Quantum-8 rope for trials really turned our operation around.

We have used your ropes for almost two years now, and are pleased to state that

Quantum-8 lasts 10 to 12 times longer than the traditional synthetics we had tried over

the previous five years…this brings about a huge savings in time previously incurred

for rope renewals, and the reduced diameter for the same strength of conventional

ropes have made mooring/unmooring a lot easier and faster.”

“I would not hesitate to recommend this rope to any operator.”

Armindo Gomes, BEng, MMgmt (project), MBA Technical Director, Canada Steamship Lines (Asia)

With the success of this installation, Samson has recently supplied another set of Quantum-8 winch lines to CSL for a new SSTP now working in Melbourne, Australia trans-shipping iron ore.

The Samson Advantage in action


Samson offers specific products to meet the needs of varying tug designs and bollard pulls for conventional or tractor tugs assist/maneuvering lines that are worked off drums or H-bitts. Our Sales and Engineering groups can assist by supplying detailed engineered solutions to improve rope performance and safety.

WHEN WORKING WITH H-BITTS: Slippage and the effect of heat build up are critical factors when working with H-bitts. The main rope for use on H-bitts

should have an outer working surface of polyester to provide the holding friction and heat protection necessary when

surging the rope. To minimize the working line weight and maximize the wear of the shipboard connecting end, a floating

lightweight AmSteel®-Blue pendant can be utilized.

FOR DRUM WORKING LINES: Since gripping and heat resistance are not as critical, the higher strength and lighter weight of an all Dyneema® fiber

rope provide the best performance. These ropes are also used with a replaceable connecting pendant to insure

maximum service life of the main working line.

When asked what has been the most significant technical advance to impact tug efficiency by Maritime Reporter & Engineering News, Tom Crowley, Jr. replied:

“Synthetic rope – it is as strong as wire, it floats, and it has enabled us to do some amazing things… the tanker escorting business is built around

these new ropes, as there’s no way you could do it without them,”

he summarized.


APSTUG APPLICATIONS

To ensure maximum service life of tug assist and maneuvering lines, Samson recommends the use of a single leg or strop pendant.

The pendants will take the abuse of rough undressed chocks and bitts aboard the assisted vessel and allow the main assist lines to be maintained. The pendants can be connected by way of cow-hitching the 1 meter soft eye of the single leg or the strop to the main line soft eye. The strop configuration can be readjusted to share the wear over the strop length.

To protect the pendants, our Pro-Gard™ Eye Protectors for the pendant eyes can be easily installed in the field or at time of order—refer to pages 10–11.

SINGLE LEG PENDANT CONFIGURATION: Standard overall length is 15.2m (50 ft.) with a 1m (3 ft.) soft eye, for mating to main line, and a 2m (6 ft.) soft eye for shipboard connection.

SINGLE LEG STROP CONFIGURATION: Standard overall length is 15.2m (50 ft.). Strop strengths are 1.6 x single leg rope strengths.

Keeping commerce moving on inland waterways is a tough job for ropes…

Inland River Applications HIGH PERFORMANCE SYNTHETIC ROPE SOLUTIONS

Working ropes for the U.S. Inland Waterways provide some of the most demanding applications for modern rope technology. These lines see more action than most in the commercial marine markets, and bear the responsibility for keeping commerce moving on our waterways. Samson meets the challenge with synthetic rope products that outperform wire and are at least as strong, if not stronger than the wire they replace. But strength is only part of the story.

The bottom line is…what does it do to your bottom line? Samson high performance synthetic ropes are lightweight and easy to

handle. Making up and knocking down is quicker and safer. AmSteel®-Blue is, size for size, as strong as wire, yet it floats. That means crews responsible for handling ropes can be reduced. Lighter weight also means fewer work-related injury claims. The lack of fish-hooks from broken strands further reduces injuries.

Modern synthetics also require little or no maintenance when properly installed. All deck hardware should be faired and repaired when the new rope is installed; after that, with reasonable care and good chafe gear, maintenance is minimal. There’s no re-lubing and end for ending is an easy operation requiring no additional equipment. Splicing for most products is a simple process that can be accomplished in the field without mechanical equipment. Best of all, with proper care, the service life is as much as three times that of wire. Add it all up and your bottom line just got a lot better.

Best of all, Samson offers a choice…non-jacketed or jacketed for wire rope replacement; and the longest wearing locklines in the business

Rather than a single line that promises to replace all your wire, Samson offers a full range of products engineered to perform in your situation and with the configuration of your vessels. Patented constructions using Samson’s DPX® technology are designed specifically for use on H-bitts and capstans where grip is a major consideration. We’ve designed double braids and single braids that excel working from winches. Even our 3-strand lockline takes full advantage of the latest technology to deliver a line that outperforms all others in the locks.

And if that isn’t enough, we also offer the best advice in the field Experienced application and sales engineers that know both the ropes and the industry can assist in determining the best product for your working routines. They also assist with installations, advise on proper fairing of existing equipment, train crews in splicing and inspecting the ropes to ensure the longest service life. It’s all part of The Samson Advantage.

But Samson high performance synthetics are up to the challenge


Commercial Fish Applications

When it comes to abusive, demanding and punishing environments for rope…

HIGH PERFORMANCE SYNTHETIC ROPE SOLUTIONS

These are some of the most productive fishing grounds in the world. They are also some of the most unforgiving and punishing seas on earth. If a rope can stand up to the constant usage and physical abuse of these fisheries, it can withstand pretty much anything. Many of our products prove themselves here before they are used for other commercial marine applications.

As if the sea states and weather weren’t enough, ropes here are spooled from winches, run off capstans, retrieved while underway, pulled by power heads, and generally subjected to more bending fatigue, shock loading and abrasion than a decade of use as a mooring line. Replacing wire ropes for many of these applications is a tough process, but the lightweight, extreme strength and ease of handling of modern synthetics have made a believer out of many a fisherman. If TrawlSteel-Blue can withstand the constant deployment, retrieval, shock loading and sheer abuse the trawl industry can dish out, it becomes the best tested winch-based mooring line in the business. That’s true for many products from the Class II high performance synthetics to the more traditional Class I ropes used in less demanding situations.

Only the survivors remain in the Samson product line… Samson manufactures a full line of products for commercial fishermen; from 3-strand lines of nylon, polyester and olefin fibers to the all Dyneema® fiber Class II extreme performance products. So many, in fact, they are not all here in the commercial marine catalog. Visit www.samsonrope.com for a complete listing of all Samson ropes for commercial fishing.

Best of all, they’re all backed by The Samson Advantage… That’s our commitment to not only provide the most innovative products, but to provide the best service in the industry. Service that includes onboard training, on-site inspections for critical applications, and full access to all our materials for splicing and technical information on the web.

Few markets can dish it out like the fishing grounds of the North Pacific and Bering Sea

Trawl-Steel-Blue evolved from the development of TrawlSteel – a rope Samson engineers designed for use, as its name suggests, in the commercial fishing market. TrawlSteel-Blue combines a 12-strand construction of 100% Dyneema® SK-75 with a control core of Samson’s 100% polyester Duravet. This combination results in a rope with the high strength, lightweight and ease of splicing of a 12-strand made with Dyneema® SK-75, yet stays round and firm – perfect for use on winch-based systems. Since the Duravet control core is not load bearing, TrawlSteel-Blue can be spliced using the standard 12-strand Class II splicing instructions.

Mooring Defender 12STRAND CONSTRUCTION

Product Code: 859

The first lightweight braided mooring line with proven reduced recoil risk

FEATURES:

> Excellent UV resistance> Easy to inspect, splice or repair onboard ship> Reduced recoil property are quantified per CI 1502 standard

APPLICATIONS:

> Primary and secondary mooring lines> General working lines> SVMS component

Mooring Defender is a 12-strand mooring line made with Dyneema® based on Samson’s unique, patented reduced recoil technology. Polyester fibers on the surface of the rope provide a high coefficient of friction, resulting in better grip. Dangerous ‘snap back’, inherent to traditionally designed ropes, can cause severe injury to rope handlers and equipment in ship mooring operations. Engineered to meet the needs of our modern US military vessels, Mooring Defender is designed to absorb the energy released by the rope when it breaks, thus reducing the tendency of the rope to recoil. Like Samson’s other high performance mooring ropes, Mooring Defender has high strength, superior abrasion resistance, and low elongation. Size for size, Mooring Defender is over twice the strength of traditional nylons and, unlike nylon, has no wet strength loss. When compared to 4-strand aramid rope, Mooring Defender is more flexible, has better UV resistance, is lighter weight, and will not hockle.

When Mooring Defender is subjected to excessive tension loads, the lower elongating fibers will break first, transferring the load to the remaining specially designed control strands. This creates an indication of rope failure before the rope becomes completely separated. In a conventional rope, the rope will break without warning, causing unpredictable and potentially dangerous movements of the broken ends.

Understanding Samson's Class I and Class II rope categories

Rope Classificationsn's Class I and Class II rope ca


Throughout this catalog, and all of Samson’s literature and specifications, you will find references to Class I or Class II ropes. Since these classes of product vary in fiber composition and constructions, splicing techniques and testing procedures are different for the two classes of product. It can be helpful to understand the differences when selecting a product for a specific application, or determining the proper splicing technique to use.

It is absolutely critical that the proper splicing technique be used when splicing Class II ropes. The Samson Splicing Manual has splicing instructions for both classes in the most common constructions and a visual reference chart for identifying products as well as both construction and class. At 158 pages, we believe it to be the most definitive reference on splicing synthetic rope available. In addition, all splicing instructions are available for download from www.samsonrope.com.

There are several distinctions between the two classes –

CLASS I ROPES: > are made from traditional synthetic fibers, or non-high modulus fibers such as olefin (polypropylene or polyethylene) nylon, polyester, or a combination of these fibers

> not considered a replacement for wire ropes

> have tenacities less than 15 grams/denier (gpd) and a total stretch at break of 6% or greater

CLASS II ROPES: > made from high performance fibers such as HMPE (Dyneema®),

Aramid (Technora®), LCP (Vectran®), PBO (ZYLON®) and carbon fiber either singularly or in combination

> are considered a replacement for wire ropes

> have tenacities greater than 15 grams/denier (gpd) and a total stretch at break of less than 6%

SSR-301RProduct Code: 226

FEATURES:

> Most cost effective lockline available> Gives long-term, smooth, consistent checking> Low working elongation for control> Excellent flex and wear resistance

The ultimate lockline specifically designed to virtually eliminate slipstick when checking barges. The 3-strand rope construction is a high strength, lightweight and controlled smooth checking line that has double the wear life of standard lockline ropes. This is accomplished by our unique fiber and internal Resistex lubricant. The core fiber of each strand is 35% stronger than standard polypropylene fiber. The core fiber of each strand then has our internally-produced outer cover of high-tenacity filament polyester blended with spun polyester. The outer cover of polyester allows for excellent wear and heat resistance. The Resistex lubricant constantly lubricates the outer surface fibers when working loads are applied. This constant migration of Resistex to the surface yarns maximizes rope wear life, allows consistent checking ability, and minimizes heat build-up during checking.

Samthane (Type A) Samthane (Type A) is a spliceable coating used on polyester and nylon fiber ropes which greatly enhances abrasion resistance. It also makes splicing used rope much easier. Available in a variety of colors for easy identification; tracks time in service, keys colors to specific operations, etc. Splicing new and used rope is easily done by utilizing the same tools and techniques for splicing uncoated rope. Coating adds approximately 3% to 5% weight to the line.

Samthane (Type F) Samthane (Type F) is a spliceable coating specially formulated for coating high modulus fibers and olefin/polyester blend ropes. Physical properties are the same as for Type A coating. Coating adds approximately 3% to 5% weight to the line.

Samthane (Type C) Samthane (Type C) is a non-spliceable jacket coating usually applied to specific sections of a line which will be subjected to extreme abrasion. The coating is very tough, with excellent resistance to cutting. It is usually applied to a thickness of 1/8" or more, which has a stiffening effect on the rope. This coating is applied to pre-spliced ropes and may also be used for thimble encapsulation.

Samthane (Type S) Samthane (Type S) is a spliceable coating used on high modulus fiber and polyester fiber ropes. This coating adds firmness and greatly improves wear life. The coating will add approximately 3% to 5% weight to the rope.

The most current and up-to-date splicing instructions for products listed in the catalog are available online at: www.samsonrope.com.

As depicted in the catalog, our rope constructions are stated as Class I and Class II ropes (see glossary of terms) and each type of rope class requires unique splicing procedures. For decades Samson has been known for supplying the most comprehensive splice instructions in the industry. Our new manual is no exception. Get your own copy today.

Fids are utilized to perform the appropriate splice procedure based on the class and type of construction.

The fids are used in making required measurements and in burying the rope during the splicing operation. Each diameter of rope has a matching fid size and to insure that the required measurements are made correctly,

the proper sized fid for the rope size must be used in performing a splice. There are two styles of fids offered: Aluminum Tubular Fids and Wire Fids. The Aluminum Tubular Fids are used by inserting the end rope section into the fid while the Wire Fids are attached to the end of the rope section. Tubular Fids are pushed through the rope with an appropriate sized pusher where Wire Fids are either fed through the rope or pulled through by attaching a feed line.

The Samson Splicing Kit comes with 5 aluminum tubular fids (size range 1/4" through 1/2" diameter)

COMPARISON OF FIBER CHARACTERISTICS(using nylon as a basis of 1.0)

1 TENACITY is the measurement of the resistance of fiber to breaking.

2 ELONGATION refers to percent elongation of fiber at break.

3 COEFFICIENT OF FRICTION is based on reluctance to slip or slide.

4 CRITICAL TEMPERATURE is defined as the point at which degradation is caused by temperature alone.

5 COLD FLOW (CREEP) is defined as fiber deformation (elongation) due to molecular slippage under a constant static loading situation. Fibers that have this inherent characteristic will display extremely low or negligible creep if minor fluctuations occur in the rate and/or frequency of load levels. In rope form, this would apply to polypropylene, polyethylene and HMPE fibers such as Spectra® and Dyneema® fiber.

ROPE CONSTRUCTION

Both Class I and Class II ropes can be produced in various rope constructions such as: 3-strand, 8-strand, 8x3-strand, 12-strand, double braids, or core-dependent braids.

All Samson ropes are categorized for splicing and testing purposes as a Class I or Class II construction.

Class I ropes are produced with non high modulus fibers that impart the strength and stretch char-acteristics to the rope which have tenacities of 15 grams/denier (gpd) or less and a total stretch at break of 6% or greater.

Class I Ropes are produced with traditional fibers such as: Olefin (Polypropylene or Polyethylene), Nylon, and Polyester.

Class II ropes are produced with high modulus fibers that impart the strength and stretch characteristics to the rope which have tenacities greater than 15 grams/denier (gpd) and a total stretch at break of less than 6%. Typical Class II ropes are produced with: HMPE (Dyneema® or Spectra®), Aramid (Technora® or Kevlar®), LCP (Vectran®), PBO (Zylon®), and Carbon fibers.

Stretch

Elastic Elongation REFREFERENCE

ELASTIC ELONGATION (E.E): Refers to the portion of stretch or extension of a rope that is immediately recoverable after the load on the rope is released. This recoverable tendency is a primary result of the fiber (or fibers) used as opposed to the rope construction. Each type of synthetic fiber inherently displays a unique degree of elasticity. Relatively, HMPE fiber has an extremely low elasticity compared to nylon fiber.

HYSTERESIS: Refers to a recoverable portion of stretch or extension over a period of time after a load is released. In measuring elastic recovery it is the recovery that occurs immediately when a load is removed; thereafter, a remaining small percentage of elastic recovery will occur slowly and gradually over a period of hours or days. This retardation in recovery is measured on a length/time scale and is known as hysteresis or recovery over time.

PERMANENT EXTENSION (P.E.) WHILE WORKING: The amount of extension which exists when stress is removed but no time is given for hysteresis recovery. It includes the non-recoverable and hysteresis extension as one value and represents any increase in the length of a rope in a constant working situation such as during repeated surges in towing or other similar cyclical operations.

The percentage of P.E. over the working load range is generally in order of four or six percent for braided ropes and two to three times as much for plaited. However, it will vary slightly with different fibers and rope constructions.

Allowances must be made for this factor in applications such as sub-surface mooring or when using devices that demand precise depth location and measurement.

PERMANENT EXTENSION (P.E.) AFTER RELAXED: That portion of extension which, due to construction deformation (compacting of braid and helical changes) and some plastic deformation of the yarn fibers, prevents the rope from returning to its original length.

CREEP (COLD FLOW): Fiber deformation (elongation) due to molecular slippage under a constant, static loading situation. Fibers with this inherent characteristic display extremely low or negligible creep if minor fluctuations occur in the rate and/or frequency of load levels. In rope form, this would apply to polypropylene, polyethylene and HMPE fibers.

Samson R&D

A WORD ABOUT PUBLISHED STRENGTHS AND TESTING: Because our ropes are asked to perform in the real world, our published strengths and test results reflect as accurately as possible the conditions under which they are intended to be used. Since nearly all ropes in actual use are terminated with a splice, publishing unspliced strengths does not allow the customer to select the appropriate size and strength rope for his application, and to assure the utmost in safety and length of service life. Throughout this catalog, and wherever SRT strengths are noted, all published data are for spliced ropes. This ensures that you are selecting sizes and strengths based on real world conditions. When comparing our data to other strengths, please ensure that spliced strengths are used.

TESTING METHODS AT SAMSON: Testing is a critical stage in the design and manufacture of new ropes, and in determining

retirement criteria for used ropes. Samson has established test methods that comply with industry standard methods like CI-1500, with more stringent specifications and testing instructions

to eliminate wide tolerances or generalized procedures, The result is more consistent, reliable data for our customers, and more accurate assessment of retirement criteria.

Samson R&D maintains the largest capacity testing machine for synthetic rope in the industry, capable of testing rope to failure up to 1.1 million pounds. The machine is fully computer controlled, provides automated cycle loading, and precise elongation measurements. All data is acquired, stored, calculations performed, and reports generated automatically.

SAMSON’S TESTING METHODOLOGY COVERS:> Sampling of test specimens

> Determination of diameter

> Determination of lay/pitch, picks per inch

> Linear density

> Breaking force

> Initial elongation (uncycled elongation)

> Cycled elongation

> Wet testing

> Reporting procedures

> Stiffness

> Abrasion resistance

More information on testing of high performance ropes is available for downloading at www.samsonrope.com. Go to the Technical Resources section directly from the home page.

RESIDUAL STRENGTH TESTING:Samson offers customers residual strength testing of our ropes. Periodic testing of samples taken from ropes currently in service ensure that retirement criteria is updated to reflect the actual conditions of service. Call our customer service department for more information. (See sample Residual Strength chart on page 55).

Synthetic-fiber rope should be removed from the reel by pulling it off the top while the reel is free to rotate.

REMOVING ROPE FROM REEL OR COIL:Synthetic fiber ropes are normally shipped on reels for maximum protection while in transit. The rope should be removed from the reel by pulling it off the top while the reel is free to rotate. This can be accomplished by passing a pipe through the center of the reel and jacking it up until the reel is free from the deck. Rope should never be taken from a reel lying on its side. If the rope is supplied on a coil, it should always be uncoiled from the inside so that the first turn comes off the bottom in a counterclockwise direction.

AVOID KINKING AND HOCKLING:The continuous use of a line on one side of a winch or windlass is a common abuse which can render a line useless in a comparatively short time. Repeated hauling of a line over a winch in a counterclockwise direction will extend the lay of the rope and simultaneously shorten the twist of each strand. As this action continues, kinks (or hockles) will develop. Once these hockles appear, they cannot be removed and the rope is permanently damaged at the point of hockling.

If, on the other hand, the line is continuously hauled over a winch in a clockwise direction, the rope lay is shortened and the rope becomes stiff and will kink readily.

To avoid detrimental conditions, the direction of turns over the winch should be alternated regularly. Clockwise turns are recommended for the initial use of a new line. If this practice is observed, the original rope balance will be maintained and the lines will have a much longer useful life.

In these examples, the condition can arise in the deep sea mooring of free-rotating buoys where a 3-strand rope will rotate until it spins and twists itself into hockles and eventually destroys itself. The use of swivels with three-strand ocean-towing hawsers, or transmission stringing lines, may also cause damaging hockles. The sudden release of a heavy strain may also cause hockles or hard kinks. Excessive turns can cause kinking in any rope but hockles can occur only in the basic “twisted” ropes (3-strand, 4-strand and cable-laid). Braided and plaited ropes cannot be hockled; their interlocking strand construction prevents the unlaying. Strands run in both directions creating a torque-free balance thus eliminating any inherent tendency toward twist or rotation. Swivels can be used safely but are seldom necessary. One word of caution here: when marrying a braided line to a twisted line (and also to wire rope) the twisted line can impart its twist to the braided line if the ropes are married without a swivel in between.

A braided or plaited rope, being torque-free, can have twist induced by constant working on winches and capstans. If a twist develops, it can easily be removed by “counter-rotating” when the rope is relaxed.

COILING AND FLAKING:3-strand ropes should be coiled in a clockwise direction (or in the direction of the lay of the rope) and uncoiled in a counterclockwise direction to avoid kinks. An alternate and perhaps better method is to flake out the line figure-eight fashion. This avoids putting twist in the line in either direction and lessens the risk of kinking.

FIGURE 8 STOWAGE METHOD:Great care must be taken in the stowage and proper coiling of 3-strand ropes to prevent the natural built-in twist of the line from developing kinks and damaging hockles. Braided ropes on the other hand have no built-in twist and are far more resistant to kinking. Even if kinks do develop they cannot develop further into hockles. The best method for making up braided rope for deck stowage is in figure-eight fashion either flaked flat on the deck or figure-eight vertically around bulkhead cleats. It should not be hand coiled in either direction as this merely puts turn into the line which may develop into kinks when paying-out. Remember that there is no turn or twist in the line to begin with so do not produce it by coiling.

Once these hockles appear, they cannot be removed and the rope is permanently damaged.

Winch Info

Bending Radius and Winch Data

Surface diameter should be at least three times the rope diameter.

Bollards with undersized horns.

Surface diameter should be at least 1/2 the rope circumference.

BENDING RADIUS:Any sharp bend in a rope under load decreases its strength substantially and may cause premature damage or failure. In sizing the radius of bitts, fairleads and chocks for best performance the following guidelines are offered:

Where a rope bends more than ten degrees around bitts or chocks or, for that matter, is bending across any surface, the diameter of that surface should not be less than three times the diameter of the rope. Stated another way, the diameter of the surface should be at least three times the rope diameter. A four-to-one ratio (or larger) would be better yet because the durability of the rope increases substantially as the diameter of the surface over which it is worked increases.

On a cleat when the rope does not bend radially around, the barrel of the cleat can be one half the rope circumference (minimum).

Many tugboats using eight and nine-inch circumference headlines in ship-handling work have fair size bitts (eighteen-inch diameter, etc.), which is an adequate bending radius. However, ironically, many of these bow and shoulder bitts are equipped with “horns” of a relatively small diameter (five or six-inches) and it is these horns under or over which the lines pass and bend first in many cases. This results in shortened rope life and excessive rope replacement costs.

The ratio of the length of an eye splice to the diameter of the object over which the eye is to be placed (bollard, bitt, cleat, etc.) should be a minimum three-to-one relationship and preferably five-to-one. In other words, if you have a bollard two feet in diameter the eye splice should be six or ten feet in length. By using this ratio the angle of the two legs of the eye splice at its throat will not be so severe as to cause a parting or tearing action at this point (thimbles are normally designed with a three-to-one ratio).

SHEAVE DIAMETERS SHOULD BE:

To assure maximum efficiency and safety, sheaves for braided ropes should be no less than eight times the rope diameter. The sheave groove diameter should be no less than ten percent greater than the rope diameter. The sheave groove should be round in shape. Sheaves with “V” shaped grooves should be avoided, as they tend to pinch and damage the rope through excessive friction and crushing of the rope fibers. Sheave surfaces should be kept smooth and free of burrs and gouges. Bearings should be maintained to ensure smooth rotation of sheaves.

EFFECT OF ROPE DIAMETER ON DRUM CAPACITY

TUG ASSIST LINES: A minimum of the first 3-4 wrap layers of rope around the winch storage drum should be installed so the rope has a close and tight fit on the drum. The installation tension on the rope should be approximately 10% of the rope’s minimum breaking strength. For new rope installations, the greater the number of wrap layers installed under the suggested tension will minimize or prevent subsequent wraps from diving or burying down into lower wraps. As the rope is used, the wrap tensions may loosen, it is suggested the total rope be re-tensioned at original installation loads and thereby prevent potential downward wrap slippage. A single drum or split drum winch, should always keep a minimum of eight wraps of rope on the drum at all times. This is to insure that the connecting point of the rope to

the winch does not under go load.8 wraps on drum

Winding rope on winch drum

MOORING LINES: The mooring line should be installed on the winch storage drum under tension that can be created by running the rope around a capstan, bollard, or pin. There are two key factors, it is important the rope be installed with tension and in a close tight fit on the drum to prevent rope diving or burying into the lower wrap layers. It is also important that the surface of the device used to create the tension is not abrasive to the rope and the installation speed or tension applied does not generate excessive heat build up on the rope. A single drum or split drum winch, should always keep a minimum of eight wraps of rope on the drum at all times. This is to ensure that the connecting point of the rope to the winch does not under go load.

In connecting the rope to the winch drum flange, it is suggested that the end of the rope either be back spliced or whipped to create better rope firmness for the flange connec-tion bracket to compress upon.

Strength Data

Standards of Strength and Determination

WORKING LOADS:Working loads are for rope in good condition with appropriate splices, in noncritical applications and under normal service conditions. Working loads are based on a percentage of the approximate breaking strength of new and unused rope of current manufacture. For the 3-strand, 8-strand, 12-strand and double braid rope products depicted in this manual, when used under normal conditions, the working load percentage is 20% of published strengths. Normal working loads do not cover dynamic conditions such as shock loads or sustained loads, nor do they cover where life, limb or valuable property are involved. In these cases a lower working load must be used. A higher working load may be selected only with expert knowledge of conditions and professional estimates of risk, if the rope has been inspected and found to be in good condition, and if the rope has not been subject to dynamic loading (such as sudden drops, snubs or pickups), excessive use, elevated temperatures, or extended periods under load.

NORMAL WORKING LOADS:Normal working loads are not applicable when rope has been subject to dynamic loading. Whenever a load is picked up, stopped, moved or swung there is an increased force due to dynamic loading. The more rapidly or suddenly such actions occur, the greater the increase will be. In extreme cases, the force put on the rope may be two, three, or even more times the normal load involved. Examples could be ropes used as a tow line, picking up a load on a slack line, or using rope to stop a falling object. Dynamic effects are greater on a low elongation rope such as polyester than on a high elongation rope such as nylon, and greater on a short rope than on a long one. Therefore, in all such applications normal working loads as given do not apply.

DYNAMIC LOADING:For dynamic loading applications involving severe exposure conditions, or for recommendations on special applications, consult the manufacturer.

DANGER TO PERSONNEL:Persons should be warned against the serious danger of standing in line with a rope under tension. Should the rope part, it may recoil with considerable force and speed. In all cases where any such risks are present, or where there is any question about the load involved or the condition of use, the working load should be substantially reduced and the rope

properly inspected before every use.

SPLICING AND KNOTS:Splices should be used instead of knots whenever possible because knots can decrease rope strength up to 50%. When splices are used, always use the manufacturer’s recommended splicing procedures. When knots are used, be sure to take into consideration the knot’s corresponding reduction to the rope strength and adjust your working load accordingly.

ROPE INSPECTION:Avoid using rope that shows signs of aging and wear. If in doubt, destroy the used rope. No type of visual inspection can be guaranteed to accurately and precisely determine the actual residual strength. When the fibers show wear in any given area, the rope should be re-spliced, downgraded, or replaced. Check the line regularly for frayed strands and broken yarns. Pulled strands should be re-threaded into the rope if possible. A pulled strand can snag on a foreign object during rope operation. Both outer and inner rope fibers contribute to the strength of the rope. When either is worn, the rope is naturally weakened. Open the strands of the rope and look for powdered fiber, which is one sign of internal wear. A heavily used rope will often become compacted or hard which indicates reduced strength. The rope should be discarded if this condition exists.

AVOID ALL ABRASIVE CONDITIONS:All rope will be severely damaged if subjected to rough surfaces or sharp edges. Chocks, bitts, winches, drums and other surfaces must be kept in good condition and free of burrs and rust. Pulleys must be free to rotate and should be of proper size to avoid excessive wear.

AVOID CHEMICAL EXPOSURE:Rope is subject to damage by chemicals. Consult the manufacturer for specific chemical exposure, such as solvents, acids, and alkalis. Consult the manufacturer for recommendations when a rope will be used where chemical exposure (either fumes or actual contact) can occur.

AVOID OVERHEATING:Heat can seriously affect the strength of synthetic ropes. The temperatures at which 50% strength loss can occur are: Polypropylene 250° F, Nylon 350° F, Polyester 350° F. When using rope where the temperature exceeds these levels (or if it is too hot to hold), consult the manufacturer for recommendations as to the size and type of rope for the proposed continuous heat exposure conditions. When using ropes on a capstan or winch, care should be exercised to avoid surging while the capstan or winch head is rotating. The friction from the slippage causes localized overheating which can melt or fuse synthetic fibers, resulting in severe loss of tensile strength.

STORAGE:All rope should be stored in a clean, dry area, out of direct sunlight, and away from extreme heat. It should be kept off the floor on racks to provide ventilation underneath. Never store on a concrete or dirt floor, and under no circumstances should cordage and acid or alkalis be kept in the same vicinity. Some synthetic rope (in particular polypropylene and polyethylene) may be severely weakened by prolonged exposure to ultraviolet (UV) rays unless specifically stabilized and/or pigmented to increase UV resistance. UV degradation is indicated by discoloration and the presence of splinters and slivers on the surface of the rope.

Selection and Usage

Rope Inspection and Retirement

1. SELECTIONSelect the rignt rope for the job in the first place.Selecting a rope involves evaluating a combination of factors. Some of these factors are straightforward like comparing rope specifications. Others are less qualitative like a preference for a specific color or how a rope feels in your hand. Cutting corners, reducing application factors, sizes or strengths on an initial purchase creates unnecessary replacements, potentially dangerous conditions and increases long term costs. Fiber and construction being equal, a larger rope will out-last a smaller rope because of the greater surface wear distribution. By the same token, a stronger rope will out-last a weaker one because it will be used at a lower percentage of its break strength with less chance of over stressing.

STRENGTH: When given a choice between ropes, select the strongest of any given size. A load of 200 pounds represents 2% of the strength of a rope with a breaking strength of 10,000 pounds. The same load represents 4% of the strength of a rope that has a breaking strength of 5,000 pounds. The weaker rope is having to work harder and as a result will have to be retired sooner.

ELONGATION: It is well accepted that ropes with lower elongation under load will give you better load control, which is a big help at complicated job sites. However, a rope with lower elongation that is shock loaded can fail without warning even though it appears to be in good shape. Low elongating ropes should be selected with the highest possible strength. Twisted rope has lower strength and more stretch. Braided rope has higher strength and lower stretch.

FIRMNESS: Select ropes that are firm and round and hold their shape during use. Soft or mushy ropes will snag easily and abrade quickly causing accelerated strength loss. A loose or mushy rope will almost always have higher break strengths than a similar rope that is firm and holds its shape because the fibers are in a straighter line, which improves strength but compromises durability.

CONSTRUCTION AND ABRASION: Rope construction plays an important role in resistance to normal wear and abrasion. Braided ropes have a basically round, smooth construction that tends to flatten out somewhat on a bearing surface. This distributes the wear over a much greater area, as opposed to the crowns of a 3-strand or, to a lesser degree, on an 8-strand rope.

All ropes should be protected against sharp and abrasive surfaces. Wire ropes tend to score and gouge chocks and bitts creating cutting edges that can damage synthetic ropes. Weld beads on repaired capstans, fairleads, etc. are equally damaging unless dressed down smoothly.

The use of rope for any purpose subjects it to friction, bending and tension. All rope hardware, sheaves,

rollers, capstans, cleats, as well as knots are, in varying degrees, damaging to the rope. It is important to

understand that rope is a moving, working, strength member and even under the most ideal conditions

will lose strength during use in any application. Maximizing the safety of rope performance is directly

related to how strength loss is managed and making sure ropes are retired from service before they can

create a dangerous situation. Ropes are serious working tools and used properly will give consistent and

reliable service. The cost of replacing a rope is extremely small when compared to the physical damage

or personnel injury a worn out rope can cause.

ROPE LIFE FACTORS AND DAMAGE ASSESSMENTThere are basically three steps to consider in providing the longest possible service life, the safest conditions and long range economy for ropes: Selection, Usage, and Retirement.

2. USAGEUse rope properly: do not abuse or shock load it. Observe recommended usage factors for bending and work loads. Keep ropes clean and eliminate abrasion whenever possible.WORKING LOADS: Working loads are the loads that a rope is subjected to in everyday activity.

They are normally expressed as a percentage of new rope strength and should not exceed 20%. A point to remember is that a rope may be severely overloaded or shock loaded in use without breaking. However, damage and strength loss may have occurred without any visible indication. The next time the rope is used under normal working loads the acquired weakness can cause it to break. Do not blame the rope, it was simply overloaded and failed from what is known as fatigue.

BENDING: Any sharp bend in a rope under load decreases its strength substantially and may cause premature damage and failure. Sheave diameters on rotating sheave blocks should be 10 times the rope diameter for twisted ropes and 8 times the rope diameter for braided ropes. The diameter on fixed pin terminations should be at least 3 times the rope diameter (i.e. the bending radius for 1/2" ropes should be 1-1/2").

KNOTS: While it is true that a knot reduces rope strength, it is also true that a knot is a convenient way to accomplish rope attachment. The strength loss is a result of the tight bends that occur in the knot. With some knots, ropes can lose up to 50% of their strength. It is vital that the reduction in strength by the use of knots be taken into account when determining the size and strength of a rope to be used in an application. To avoid knot strength reduction, it is recommended that a rope be spliced according to the manufacturer’s instructions. Splice terminations are used in all our ropes to determine new and unused tensile strengths. Therefore, whenever possible, spliced terminations should be used to maximize the rope strength for new and used ropes.

ROPE STORAGE: Keep your ropes as clean and dry as possible and store them in a coil away from heat sources.

SHOCK LOADS: Shock loads are simply a sudden change in tension from a state of relaxation or low load to one of high load. Any sudden load that exceeds the work load by more than 10% is considered a shock load. The further an object falls, the greater the impact. Synthetic fibers have a memory and retain the effects of being overloaded or shock loaded and can fail at a later time even though loaded within the work load range.

RECOMMENDED WORK LOAD LIMIT: For catalogued ropes:

Rope Construction Percentage of Strength Break

3-Strand 20%

8-Strand 20%

12-Strand 20%

Double Braid 20%

CONSTRUCTION WORKING LOAD

3. RETIREMENT Retire rope from use when it has reached its discard point.. One of the most frequently asked questions is “When should I retire my rope?” The most obvious answer is before it breaks. But, without a thorough understanding of how to inspect it and knowing the load history, you are left making an educated guess. Unfortunately, there are no definitive rules nor industry guidelines to establish when a rope should be retired because there are so many variables that affect rope strength. Factors like load history, bending radius, abrasion, chemical exposure or some combination of those factors, make retirement decisions difficult. Inspecting your rope should be a continuous process of observation before, during and after each use. In synthetic fiber ropes the amount of strength loss due to abrasion and/or flexing is directly related to the amount of broken fiber in the rope’s cross section. After each use, look and feel along every inch of the rope length inspecting for abrasion, glossy or glazed areas, inconsistent diameter, discoloration, and inconsistencies in texture and stiffness.

UNDERSTANDING THE ROPE DESIGN/CONSTRUCTION: It is first important to understand the design of the specific rope in use. Most ropes are designed to have features specifically tailored to their application. These features can lead to misconceptions during visual inspections. When a rope has a braided cover, it is only possible to visually inspect the cover (which, at best, carries only 50% of the load). Rope designs utilizing HMPE fibers will show initial rapid abrasion until the rope has a fuzzy appearance — this appearance actually acts as a protective layer.

DETERMINING THE AVERAGE CONDITION OF THE ROPE: The average condition of a rope can be an important factor in determining the rope’s retirement. To determine the average condition, walk the entire length of the rope and document its overall condition. Many ropes can be classified by the total amount of overall wear and cleanliness.

fig. 5 Inspect for internal abrasion

fig. 6 Compare surface yarns with internal yarns

ABRASION:

When the rope is first put into service the outer filaments of the rope will quickly fuzz up (fig. 2). This is the result of these filaments breaking and this roughened surface actually forms a protective cushion and shield for the fibers underneath. This condition should stabilize, not progress.

If the surface roughness increases (fig. 3), excessive abrasion is taking place and strength is being lost. As a general rule for single braid ropes, when there is 25% or more wear from abrasion the rope should be retired from service. In other words, if 25% or more of the fiber is broken or worn away the rope should be removed from service. With 3-strand ropes, 10% or more wear is accepted as the retirement point.

LOCATE AREAS DEVIATING FROM AVERAGE:

Many times a rope will have areas that are routinely used around a bit, through a chock, or buried on the winch drum. These areas typically have different wear patterns than the average condition of the rope. Pay close attention to these areas in the future and frequently examine them for rapid changes in appearance.

Look closely at both the inner and outer fibers. When either is worn the rope is obviously weakened. Open the strands and look for powdered fiber, which is one sign of internal wear. Estimate the internal wear to estimate total fiber abrasion.

If total fiber loss is 20%, then it is safe to assume that the rope has lost 20% of its strength as a result of abrasion.

Internal abrasion can be determined by pulling one strand away from the others and looking for powdered or broken fiber filaments (fig. 4 and fig. 5).

To determine the extent of outer fiber damage from abrasion, a single yarn in all abraded areas should be examined. The diameter of the abraded yarn should then be compared to a portion of the same yarn or an adjacent yarn of the same type that has been protected by the strand crossover area and is free from abrasion damage. (fig. 6).

It should be noted that comparing diameters of the yarns does not give an accurate measure of the retained strength. Since the strength should depend on the cross-sectional area of the yarn, a diameter difference alone will underestimate the true abrasion reduction. If the diameter of the abraded yarn is 1/2 the diameter of the internal yarn, the strength of the abraded yarn is nearly 1/4 that of the internal yarn.

Determining the extent of fiber loss due to abrasion can be difficult. Since all the strands are twisted, the outer fibers, which are the most prone to abrasion damage, rotate through the rope’s length. Therefore on a single strand, the fibers that have been abraded on one pick, are not necessarily the fibers being abraded on the next. However, over a long distance, a single yarn could have the majority of fiber loss due to abrasion.

fig. 7 Compressed areas

fig. 8 Bird cage

GLOSSY OR GLAZED AREAS: Glossing or glazing can occur from two different mechanisms. The most common and

relatively benign form of glossing or glazing on a rope is generally caused by compression (fig.7), which typically occurs when the rope is wound on the winch drum, around bits, or through chocks or staples. This form of glossing can be determined on 8- and 12-strand products by compressing the rope length wise forming a “bird cage” (fig.8).

After numerous “bird cage” cycles the glossy region will become more pliable and begin to resemble normal rope. If the glazed section remains hardened, this could be a sign of heat damage. Heat damaged rope typically has more strength loss than the amount of melted fiber indicates. Fibers adjacent to the melted areas are probably damaged from excessive heat even though they appear normal. It is reasonable to assume that the melted fiber has damaged an equal amount of adjacent unmelted fiber.

INCONSISTENT DIAMETER: Inspect for flat areas, bumps or lumps. This can indicate core or internal damage from

overloading or shock loads and is usually sufficient reason to replace the rope.

DISCOLORATION: With use, all ropes get dirty. Be on the lookout for areas of discoloration which could

be caused by chemical contamination. Determine the cause of the discoloration and replace the rope if it is brittle or stiff.

INCONSISTENCY IN TEXTURE AND STIFFNESS: Can indicate excessive dirt or grit embedded in the rope or shock load damage

and is usually reason to replace the rope.

TEMPERATURE:

CHARRING POINT:High temperatures can be achieved when surging rope on a capstan or drum end, checking ropes on bitts, and running over stuck or non-rolling sheaves or rollers. Each rope’s construction and fiber type will yield a different coefficient of friction (reluctance to slip) in a new and used state. It is important to understand the operational demands and ensure the size, rope construction and fiber type be taken into account to minimize heat buildup.

Never let ropes under tension rub together or move relative to one another. Enough heat to melt the fibers can buildup and cause the rope to fail as quickly as if it had been cut with a knife.

Always be aware of areas of heat buildup and take steps to minimize it; under no circumstances let any rope come in contact with a steam line or any other hot surfaces.

The strength of a used rope can be determined by testing but the rope is destroyed in the process so the ability to determine the retirement point before it fails in service is essential. That ability is based on a combination of education in rope use and construction along with good judgment and experience.

When using rope, friction can be your best friend or worst enemy if it is not managed properly. By definition, friction creates heat, the greater the friction the greater the heat buildup. Heat is an enemy to synthetic fiber and elevated temperatures can drastically reduce the strength and/or cause rope melt-through.

The critical and melting temperatures for synthetic fibers are listed below:

POLYPROPYLENE 250° F 330° F

HMPE 150° F 300° F

ABRASION RESISTANCE: The ability of a fiber or rope to withstand surface wear and rubbing due to motion against other fibers or rope components (internal abrasion) or a contact surface such as wraps on a winch drum (external abrasion), which can be a portion of the rope itself.

BLOCK CREEL: A method of rope making where a given length of rope is produced from a ropemaking machine where all the subcomponents of the rope structure are continuous without splices. The term arises from filling all creels or bobbins to maximum (block creels) and ending rope making when the first one empties.

BRAID: n. A rope or textile structure formed by a braiding process. v. The intertwining of strands in a braiding process to produce a tubular rope structure.

BRAID, DOUBLE: A rope constructed from an inner hollow braided rope (core) which has another hollow braided rope constructed around its exterior (cover). Core and cover may be either plain or twill braid and both share any load on the rope, but not necessarily in equal amounts. Also called “braid-on-braid.”

BRAID, HOLLOW (Also: Braid, Single; Braid, Diamond): A single braid rope construction of either plain or twill braid. The center is hollow. On the surface all strands are parallel to the axis.

BRAID, SOLID: A cylindrical braid in which each strand alternately passes under and over one or more of the other strands of the rope while all strands are rotating around the axis with the same direction of rotation. On the surface, all strands appear to be parallel to the axis.

BRAIDER SPLICE: In a braided rope, the continuation of a single interrupted strand (or multiple strands) with another identical strand, which is braided from the same carrier. The interrupted and replacement strands are arranged in parallel over some distance, and are buried, or tucked, into the braid so as to secure them into the braid. To maintain maximum strength, the strands should overlap one another for a sufficient distance.

BREAKING LENGTH: A convenient term for comparing the strength-to-weight ratio of textile structures from one product to another. The calculated length of a specimen whose weight is equal to the breaking load.

BREAKING STRENGTH: For cordage, the nominal force (or load) that would be expected to break or rupture a single specimen in a tensile test conducted under a specified procedure. On a group of like specimens it may be expressed as an average or as a minimum based on statistical analysis.

Note: Breaking force refers to an external force applied to an individual specimen to produce rupture, whereas breaking strength

preferably should be restricted to the characteristic average force required to rupture several specimens of a sample. While the breaking strength is numerically equal to the breaking force for an individual specimen, the average breaking force observed for two or more specimens of a specific sample is referred to or used as the breaking strength of the sample.

BREAKING STRENGTH, MINIMUM: Cordage Institute standard. A value based on a statistically significant number of breaking load tests and the standard deviation used to establish the minimum value.

CLASS I ROPE: Rope constructions produced with non high modulus fibers that impart the strength and stretch characteristics to the rope which have tenacities of 15 grams/denier (gpd) or less and a total stretch at break of 6% or greater. Typical Class I ropes are produced with traditional fibers such as: olefin (polypropylene or polyethylene), nylon, and polyester. These fibers can be used in combination or singularly in the various rope constructions such as: 3-strand, 8-strand, 12-strand braids, double braids, or core-dependent braids.

CLASS II ROPE: Rope constructions produced with high modulus fibers that impart the strength and stretch characteristics to the rope which have tenacities greater than 15 grams/denier (gpd) and a total stretch at break of less than 6%. Typical Class II ropes are produced with: HMPE (Dyneema® fiber or Spectra®), Aramid (Technora® or Kevlar®), LCP (Vectran®), PBO (ZYLON®), and Carbon fibers. These fibers can be used in combination or singularly in the various ropes constructions such as: 3-strand, 8-strand, 12-strand, double braids, or core-dependent braids.

CORE-DEPENDENT BRAIDS: Cover braided rope constructions that utilize an internal core member or members to create the strength and stretch characteristics of the rope. The primary function of the external cover braid is to contain the core or cores and create the degree of rope firmness desired. Based on the fiber or combination of fibers used in the cover braid, the following characteristics of the rope can be altered: coefficient of friction, wear resistance, specific gravity, and heat resistance due to friction. Core-dependent braided ropes typically have internal strength members produced with parallel bundled fiber cores, a single braid core, multiple braid cores, or multiple 3 strand cores. This type of rope construction can be produced with traditional fibers, high modulus fibers, or combinations of both fiber groups, and offers the potential of creating a wide range of design parameters.

CYCLE LENGTH: The length along the axis required for a strand to make one revolution around the rope.

DEGRADATION: The loss of desirable physical properties by a textile material due to some process of physical/chemical phenomenon.

DENIER: The system used internationally for the numbering of silk and man-made filament yarns, except glass yarns. It is the primary unit for determining the size of a yarn and is based on its linear density. Officially, it is defined as the number unit weights of 0.05 grams per 450-meter length. Denier is equivalent numerically to the number of grams per 9,000 meters. In the English numbering system, 1 denier equals 4,464,528 yards to the pound. Denier is also used to indicate the thickness of a man-made fiber staple. For example, a staple is said to be 3 denier if 1,488,176 linear yards of the staple (were it continuous) would weigh one pound. The metric equivalent is Tex, the grams mass of 10,000 meters of yarn.

DYNAMIC LOAD (for cordage): Any rapidly applied load that increases the load significantly above the normal static load when lifting or suspending a weight. Dynamic effects are greater on a low elongation rope such as manila than on a higher elongation rope such as nylon, and greater on a shorter rope than on a longer one. Also, any rapidly applied load to cordage that may change its properties significantly when compared to slowly applied loads.

EXTRUSION: For polymer filaments. The process of producing filaments by forcing a polymer through a die.

FATIGUE: The tendency of a material to weaken or fail during alternate tension-tension or tension-compression cycles. In cordage, particularly at loads well below the breaking strength, this degradation is often caused by internal abrasion of the fibers and yarns but may also be caused by fiber damage due to compression. Some fibers develop cracks or splits that cause failure, especially at relatively high loads.

FIBER: A long, fine, very flexible structure that may be woven, braided, or twisted into a variety of fabrics, twine, cordage or rope.

FINISH: An oil, emulsion, lubricant or the like, applied to fibers to prevent damage during textile processing or to improve performance during use of the product.

HYDROLYSIS: The attack of the water ions on polymeric molecules, which results in polymer chain scission and loss of the fiber’s physical properties.

LAID ROPES: Ropes made by twisting of three or more strands together with the twist direction opposite that of the strands.

LAY LENGTH: The actual distance required to make one complete revolution around the axis in any element in a strand, cord or rope.
