ISO13797:2020 Specifications Mooring Bollards High Strength T Head Marine Cast Iron Bollards

Description

Mooring bollards, also known as marine bollards, are highly stable and provide secured tie-up points for mooring lines. They are simple and cost-effective measures in achieving mooring requirements such as anchoring vessels safely alongside jetties/quay, berths, wharves and dolphins in ports and harbors.

DockFender provides bollards in a range of design profiles, sizes, and mooring line capacities to suit all mooring system applications. ESC engineers also assist its clients in determining all the dimensional requirements and discuss suggestions in order to guarantee the mooring processes are safe.

Specifications

The shape of DockFender bollards has been refined with finite element techniques to optimize the geometry and anchor layout. Even at full working load, Trelleborg bollards remain highly stable and provide a safe and secure mooring operation.

These are Tee Head, Horn Staghorn, Pillar, Kidney, Cleat, Single Bitt and Double Bitt.

Features

1. Small and very large load capacity sizes, usually from 10 tons to 200 tons.

2. Rugged and durable design, extremely low maintenance.

3. Narrow footprint for limited space installations.

4. Multiple mooring line capabilities.

5. High stability and high corrosion resistance.

6. Suitable for a steeper rope.

Applications

● Bulk mineral & liquid terminal berths

● Local authority, Recreational jetties & marinas

● Container Terminals

● Commercial Ro-Ro, ferry, fishing wharfs

● Industrial Oil & Gas Terminals

Coating System

Mooring Bollards are supplied as factory standard with a protective coating suitable for most projects. High performance epoxy or other specified paint system can be factory applied on request in a choice of colors and thicknesses. Standard available coatings include (uncoated, zinc oxide primer or high performance epoxy).

Mooring Bollards are also available and supplied with Hot Dip Galvanized (HDG) on special request basis. Wear and abrasion from ropes means paint coatings need regular maintenance. Ductile iron bollards are far less susceptible to corrosion than cast steel bollards, which can rust quickly and will need frequent painting to retain full strength.

Quality Assurance

Mooring Bollards are safety critical items and quality is paramount. Independent third party witnessing of test is available at additional cost on request. A typical quality documentation package will include:

• Dimensioned drawings of bollard and accessories
• Bollard and anchorage calculations (if required)
• Inspection and test plan
• Certificate of conformance
• Physical, chemical and material properties report for casting and anchorages
• Installation guidelines
