01 N&P Lifeboat Service

With below inormation, N&P Maritime- und Industrietechnik GmbH wouldlike to introduce the scope o work which is necessary or the annual in-spection o the lie saving appliances.

The service is based on the SOLAS MSC 1206 (26 May 2006) and shall ensurethe saety o lieboats and davits and assure the ull and sae unctioningo these.

This standard procedure has to be perormed every year by a proessionallytrained service company.We have gathered our experiences through many inspections and herewith

oer inormation on how the inspection will take place and how you cansupport and assure saety on board.

It is the main reason o these inspections to assure the saety o all personson board and to avoid accidents during drills, emergencies and mainte-nance.

This procedure applies to MSC.1/Circ.1206

02 MEASURES TO PREVENT ACCIDENTS WITH LIFEBOATS

Please be sure that all parties involved in this procedure shall do their ut-most possible to prevent accidents, which usually happen due to ollowing

acts:

2.1 Failure o on-load release mechanism;2.2 Inadvertent operation o on-load release mechanism;2.3 Inadequate maintenance o lieboats, davits and launching

equipment;2.4 Communication ailures;2.5 Lack o amiliarity with lieboats, davits, equipment and associated

controls;2.6. Unsae practices during lieboat drills and inspections; and

2.7 Design aults other than on-load release mechanisms.

In order to avoid beore mentioned dangers, we kindly ask or the ull sup-port o all involved parties by:

_Supply o assistance by trained crew members

_Support in case any help or securing shall be needed_Keeping an eye on saety at all times to assure no involved and /or unin-

volved person can be harmed (e.g. somebody standing in slewing area o

davits and/or below lie/rescue boats)_Telling known problems with the equipment beore hand to avoid any

accidents due to known malunctions or damaged parts

Always remember, the annual and 5-year inspection is or yourown saety in case o an emergency.

Also during voyages:In case o any problems with your lie saving equipment, alwaysconsult a proessional service company.

FREQUENTLY ASKED QUESTIONS:

How long does the inspection take?

Usually the inspection takes between our and eight hours de-

pending on the condition o the equipment, weather and portregulations

What i the port authorities do not allow

the lowering o boats on the shore side or

even both sides?

In case the port authorities deny any moving o the shore side davits, it is

best to talk with the classication/ or fag state representative and ask iit is possible to lower the shore side boat as soon as possible on the next

anchorage or in the next port. It might be necessary to document this withpictures. Depending on the classication- and/or fag state representative it

might be necessary or them to be present or the second test too.

What i the service company is not autho-

rized rom the manuacturer o the davits

or boats?

Please consult the N&P or West Marine sales personnel or advice on fagstates regulation. Some fag states have to issue written approval to allow

independent service providers other than maker trained service station

What happens i my boat(s) and/or davit(s)

are not t or operation?

Depending on the damage or malunction o the boat or davit,the damage must be repaired as soon as possible. I serious malunction isgiven and it is not possible to use the lie- and/or rescue boat, the malunc-

tion/damage must be repaired beore the vessel is leaving the port.Our technicians are not allowed to issue a statement o tness or not cor-

rectly unctioning boats or davits.

In which time period can I order the inspec-

tion?

The inspection certicates (Statement o tness) are valid or

one year. The next inspection can be perormed earliest 4 weeks beoredue date and shall not be perormed later than 4 weeks ater the due date.Should the vessel not be able to order a service in this time (e.g. due to theschedule or unavailability o a service company), the fag state and classi-

cation must be inormed, so that a solution can be oered by these.


27/40

Must the classication/fag state attend

the inspection?

I the service company is authorized by the manuacturers, theclassication/fag state representative must not attend the inspection.

Should the service company not be authorized or both manuacturers,

the classication must attend the inspection.Should it be the 5-year inspection, the classication must always attend theinspection, no matter i the company is ully authorized or not.

Must the service station be accepted by

the fag state?

In many cases the fag states have passed the responsibility o ser-vicing the lie saving equipment to the classication companies. In so arthe classication must accept the service company. In some cases the fag

state must accept the service company directly. In these cases a letter oexemption will be needed. This has to be applied or beore the serviceis perormed, by contacting the fag state in advance through the vesselsowner company.

Must the crew attend the inspection?

It is always better to have the responsible crew members to at-tend the inspection. Through this it is always assured that ullest

saety is given and that the crew members pass on known problems o the

equipment.

What can we do to assure the ull unction

o the lie saving appliances between the

services?

First it is most important to always keep an eye on the condition o the

davits, hook systems and lie- rescue boats. In case any damage is noted,it shall be reported directly and depending on the damage must beassured that the damage shall be repaired as soon as possible.

I possible, always use a qualied service company or the repair to assurethe sae unction o all parts ater the repair.

Furthermore, always make sure the hooks and all moving parts are well

greased to avoid corrosion.Do not paint movable parts on the hooks or davits. It is oten seen thathooks are stuck due to several layers o paint or because o lack o grea-sing.

I the boat will be lowered to water during regular drills, always assure thatthe hook systems are in good condition. Open and close the hooks a ew


28/40

times, look closely when open i there is any paint or dirt inside andcheck i all parts are in good condition.

In case there are any problems with the equipment, always consult a qua-lied service company to help solve the problem. Do not make any mo-

dications on the equipment unless allowed so by the manuacturer andclassication/fag state.

Further more never apply rough orces to the brake system. In case younotice the brake is not working properly, always contact proessional ser-vice stations or the manuacturer! You cannot take the risk to damage one

o the most important saety eatures o your lie saving equipment!

MEASURES TO PREVENT ACCIDENTS WITH LIFEBOATS

1 The Maritime Saety Committee, at its eighty-rst session 10 to 19 May2006, recalled that at its seventy-th session (15 to 24 May 2002), it had

considered the issue o the unacceptably high number o accidents withlieboats in which crew were being injured, sometimes atally, while partici-

pating in lieboat drills and/or inspections, and noted that most accidentsell under the ollowing categories:

ailure o on-load release mechanism;inadvertent operation o on-load release mechanism;inadequate maintenance o lieboats, davits and launchingequipment;

communication ailures;lack o amiliarity with lieboats, davits, equipment and associatedcontrols;

unsae practices during lieboat drills and inspections; anddesign aults other than on-load release mechanisms.

2 Pending urther consideration o the problem, the Committee ap-

proved MSC/Circ.1049 on Accidents with lieboats, to draw the attention omanuacturers, shipowners, crews and classication societies to the per-sonal injury and loss o lie that may ollow inadequate attention to the

design, construction, maintenance and operation o lieboats, davits andassociated equipment and urged all concerned to take necessary action toprevent urther accidents with lieboats. It invited Member Governments to:2.1. bring the circular to the attention o their maritime Administrations,

relevant industry organizations, manuacturers, shipowners, crewsand classication societies;

1.2.3.

4.5.

6.7.

3.4 maintenance o lieboats, launching appliances and associated equip

ment is carried out in accordance with approved established procedures;

3.5 lieboat drills are conducted in accordance with SOLAS regulationIII/19.3.3 or the purpose o ensuring that ships personnel will be

able to saely embark and launch the lieboats in an emergency;

3.6 the principles o saety and health at work apply to drills as well;

3.7 personnel undertaking maintenance and repair activities are appro

priately qualied;

3.8 hanging-o pennants should only be used or maintenance purposes and not during training exercises;

3.9 all tests required or the design and approval o lie-saving appliancesare conducted rigorously, according to the guidelines developed by

the Organization, in order to identiy and rectiy any design aults at an earlystage;

3.10 the equipment is easily accessible or inspections and maintenance

and is proven durable in harsh operational conditions, in addition towith standing prototype tests; and


31/40

3.11 the approving authorities or bodies pay close attention to properworkmanship and state-o-the-art possibilities when assessing equipment or approval; and

3.12 encourage shipowners, when undertaking maintenance and repair

activities, to employ qualied personnel, preerably certied by themanuacturer.

3.13 Member Governments were urther invited, while enorcing theprovisions o SOLAS regulation IX/4.3, to ensure that the above issues

are addressed through the Saety Management System o the company, as appropriate.

4 The Committee urther recalled that, at its seventy-seventh session (28

May to 6 June 2003), recognizing the experience gained since the approvalo the Guidelines on inspection and maintenance o lieboat on-load releasegear (MSC/Circ.614) at its sixty-second session (24 to 28 May 1993), and thatthe implementation o expanded and improved guidelines could contribute

towards a reduction o the incidence o accidents with lieboats, it had ap-proved the Guidelines or periodic servicing and maintenance o lieboats,launching appliances and on-load release gear (MSC/Circ.1093), superse-

ding MSC/Circ.614. Taking into account subsequent amendments to SOLASchapter III and the LSA Code, and having considered proposals by the tieth

session o the Sub-Committee on Fire Protection, the Committee approvedamendments to the Guidelines as set out in annex 1. The Committee urther

noted that the guidance developed or lieboats could also apply to the pe-riodic servicing and maintenance o lierats, rescue boats and ast rescueboats and their launching appliances and on-load release gear.

5 The Committee urther recalled that, at its seventy-ninth session (1 to10 December 2004), it had endorsed the intention o the Sub-Committeeon Ship Design and Equipment, in co-operation with the Sub-Committee on

Standards o Training and Watchkeeping, to develop urther IMO guidanceas envisioned in MSC/Circ.1049, and accordingly, approved the Guidanceon saety during abandon ship drills using lieboats (MSC/Circ.1136), as set

out in annex 2. The Committee urther recalled that the Guidance develo-ped or lieboats has relevance, in general, or emergency drills with otherlie-saving systems and should be taken into account when such drills areconducted. In connection with MSC/Circ.1136, and recognizing the need to

provide a basic outline o essential steps to saely carry out simulated laun-ching o ree-all lieboats in accordance with SOLAS regulation III/19.3.3.4,and having considered proposals by the orty-seventh session o the Sub-


32/40

Committee on Design and Equipment, the Committee urther approvedthe Guidelines or simulated launching o ree-all lieboats (MSC/Circ.1137),as set out in the appendix to annex 2.

6 Having considered the need to update several o the circulars dis-

cussed above, and having considered proposals by the tieth session othe Sub-Committee on Fire Protection to consolidate the numerous cir-

culars on the subject o measures to prevent accidents with lieboats inorder to better serve the mariner, the Committee approved the annexedGuidelines or periodic servicing and maintenance o lieboats, launching

appliances and on-load release gear (annex 1) and Guidelines on saety du-ring abandon ship drills using lieboats (annex 2).

7 Member Governments are invited to give eect to the annexed Gui-

delines as soon as possible and to bring them to the attention o shipow-ners, ship operators, ship-vetting organizations, ship personnel, surveyors,manuacturers and all others concerned with the inspection and mainte-nance o lieboats, lierats, rescue boats and ast rescue boats and their

launching appliances and on-load release gear.
