LGRIG® Marine Double Bollard GBT554-2008 Type A

Marine Double Bollard, also known as Double Bitt Boat Bollard.

GBT 554-2008 specifies technical requirements and testing methods for marine bollards, with Type A single bitt bollards designed for vessel mooring in ports and marine environments.

Constructed from cast iron or cast steel, these bollards feature nominal diameters ranging from 100mm to 800mm, with corresponding load capacities from 20 kN to 800 kN.

The standard defines critical dimensions—including bollard height, mounting hole diameter, and head angle—to ensure compatibility with standard mooring ropes and effective vessel securing.

Mandatory testing protocols encompass proof load verification, hardness testing, and visual defect inspection. Engineered to endure harsh marine conditions, Type A bollards provide robust, reliable mooring solutions that meet standardized performance and safety requirements.
