LGRIG® Marine Double Bollard ISO 13795-2012 Type B

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

ISO 13795-2012 Type B is a German standard that defines the design and construction specifications for marine double bollards, which are short, sturdy posts used to secure mooring ropes or cables for vessels.

Specifically engineered for larger ships such as cargo carriers, tankers, and cruise liners, these bollards are built to endure the high forces generated during mooring operations.

Constructed from high-quality steel plate, they must withstand a breaking force of at least 50% of the maximum working load while offering corrosion resistance for long-term durability in marine environments.

The design features two vertically aligned bollards connected by a horizontal crossbar, providing enhanced stability and the capability to secure two ropes simultaneously.

The standard outlines precise dimensions, tolerances for height, width, and diameter, as well as guidelines for proper installation and maintenance to ensure safe and reliable performance.
