LGRIG® Marine Double Bollard ISO 13795-2012 Type A

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

ISO 13795-2012 specifies the requirements and dimensions for Type A marine double bollards, which are used for mooring and towing operations on ships and in port facilities.

The bollard consists of two symmetrically arranged vertical horns with a circular cross-section and uniform diameter, mounted on a base plate and connected by a crossbeam.

The standard defines the minimum dimensions of the horns and base plate, the spacing between the horns, and the height of the crossbeam, along with the maximum load capacity.

Typically fabricated from steel or other durable materials to withstand harsh marine conditions, Type A double bollards are widely employed in ports and harbors for securing large vessels such as tankers and container ships.
