Bollard

A bollard is the mooring fitting on a quay, jetty, or dolphin to which a ship’s lines are made fast. Its safe working load, set by the design mooring-line load, governs spacing along the berth and the local reinforcement of the quay deck. Mooring-bollard loads come from the OCIMF MEG4 methodology and PIANC guidance, which size the fitting against the line breaking loads and the environmental forces of wind and current on the moored ship. Overloaded or corroded bollards have failed under load, injuring crew.
