What is a double bollard?

Double bollards, welded steel according to the IMO 1175 standard, are designed to provide a safe and stable mooring point for vessels. The two pedestals (tubes) of the bitt provide robustness and stability to the mooring.

Starting from an international NS standard, we have developed a highly resistant bollard that, while keeping the overall dimensions contained, currently has the highest SWL (working loads) in the world.

A significant advantage is the customization capability: the tube heights can be personalized and certified according to the specific requirements of the vessel and shipowner.
