LGRIG® Marine Double Bollard JIS F2001-1995

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

JIS F2001-1995 specifies the design, dimensional, and testing requirements for marine double bollards used to secure vessels at piers or wharves.

These bollards are constructed from cast iron or steel and consist of two vertical horns connected by a crossbeam, which evenly distributes mooring line loads to minimize risk of damage.

The standard defines precise dimensions for horn height and diameter as well as crossbeam length and width, and establishes minimum breaking load requirements.

Bollards undergo rigorous testing—including load tests and visual inspections—to verify strength and durability under operational conditions.

By ensuring structural reliability and safe performance, the standard helps prevent accidents and protect maritime infrastructure.
