Metallic bollards have progressed from the original 17th

century practice of partially burying obsolete

cannon muzzle fist in a quay to provide a place for ships to secure mooring ropes. Today the bollards

provided by Hi Tech are scientifically engineered structures manufactured in either spherical graphite

iron (ductile iron) or cast steel. Designed to maintain stability and strength under working loads from

large ships subjected to wave and swell action, today’s bollards will provide decades of service given

proper maintenance.

As standard components Hi-Tech produces three types of bollards, the twin horn, the barrel type and

the tee type, cast in various sizes these bollards can meet any mooring requirement.

Attributes:

• Ductile cast iron (standard) provides high strength and good corrosion resistance

• Cast steel provides highest strength but susceptible to corrosion

• Proven designs

• Low maintenance

• Wide range of ship moorings possible

• Custom designs on request

3.1 INSTALLATION Careful installation of bollards is critical to their proper function and long life. Bollards may be surface mounted or recessed into the dock surface and may be held with either cast in anchors, through anchors or drilled and epoxy anchors.. If the bollards are recessed it is important to fill the recess with grout once installation is complete to avoid the bollard base sitting in a pool of water. Anchors must be positioned accurately both in relation to each other and in depth (or height of projection). Improper placement in relation with the other anchors will result in the bollard base holes not fitting properly and at a minimum causing damage to the bollards protective coatings. Anchors that are not proper in depth may protrude above the counter sink space in the bollard base thus interfering with the mooring ropes or they may not properly engage the anchor nuts thus weakening the bollard. 3.2 DESIGN Hi Tech bollards are designed based on BS 5950:2000 and BS 6349 Part 2: 1988 and have a safety factor of 3.0. Standard casting material is SG iron grade 65-45-12. Different standards and different materials can be accommodated upon request. Design calculations can be provided upon request. Material and process inspection and testing is available to customers upon request. 3.3 MATERIAL & PAINT COATING 3.3.1 Material Specification

Bollard Material: CAST IRON Fasteners Material: M.S. Epoxy Coated.

3.3.2 Inspection & Testing

3.3.2-A Mechanical or Chemical Test:

As per IS 210‐1978 Grade FG 150 such as Tensile Strength, Transverse Strength, Brinell Hardness etc. on the test bar.

Test report of approved laboratory will be provided.

3.3.2-B Method of Testing:

The pouring of the casting will be done in presence of inspection agency & at the same time test bar will be taken from same lot.

The test bar will be stamped by inspection agency & will be send to approved laboratory for testing.

Report will be obtained & reviewed by inspection agency.

3.3.3 Dimensional Check

After the raw material testing & the clearance given by inspection agency, bollard will be offered for dimensional inspection as per Drawing

All the dimensions will be checked by inspection agency including surface finish. 3.3.4 Painting

Sand blasting, where ever sand blasting is not possible surface will be cleaned by scraper wire brush & pig hammer.

One coat of Zinc rich primer of 60 m DFT thickness. Two coats of High Build Epoxy (DFT 125 m each) Total Painting Thickness = 310 m DFT minimum.

The selection of bollards for a pier, their spacing and arrangement is governed by published standards and local specifications. To determination proper bollards and locations for a pier one normally has to consider:

• Tidal conditions • Wind and current forces • Wave and swell conditions • Vessel draft changes due to loading or unloading • Mooring line types and sizes

Mooring forces are complex and should always be calculated to insure proper design requirements. However, as a thumb rule guideline for quick reference the following table (Table 4.1) is provided.

TABLE 4.1: Bollard Selection

MOORING LINE ANGLES

The calculation of mooring line angles should be done as part of the calculations in determining the size and location of bollards for a pier. Mooring line angles determine the forces applied to bollards and greatly affect their effectiveness. Much study has gone into determining the optimal mooring line angles for different mooring situations and the results published in such standards as BS 6349-Part 4 should be consulted.

Hi Tech bollards are designed to operate with horizontal mooring angles of +/- 90o and vertical angles of up to 75o

.

The table below gives nominal mooring line angles, derived from the standards shown, for the lines listed. In

the case where the mooring lines are going to be outside the given parameters please contact the nearest Hi-Tech representative so the conditions may be analyzed by our engineers.

Hi Tech follows a Quality Assurance Plan with the manufacturing of all its bollards. This plan will be

provided to the customer before manufacturing commences and typically includes the following for

both the bollard and the anchors:

• Material testing

• Dimensional checking

• Finishing testing

Other testing and inspection may be conducted at customer’s request. Below shown is sample of

Bollard Quality Assurance Plan as followed at Hi-Tech.
