Mooring facilities include edge bollards, mooring hooks, recessed bollards (for reinforced concrete walls), dolphin bollards, mooring rings, etc. All these items must be designed in such a way that they are easy to repair or replace.


Bollards along the top edge of the quay wall can be provided in the form of single or double bollards depending on the line pull. They are made from high-quality grey cast iron or cast steel, with fixings made from grade S 355 J2 +N or 8.8. They can either be mounted on the top of a steel capping beam or anchored in a concrete foundation behind the beam. Depending on the design, they may need to be anchored back into the ground. Break-off anchorages designed for the nominal load can be provided to avoid excessive line pull loads from overloading the sheet pile wall.

Apart from bollards along the top edge of the quay wall, it may be necessary to provide further bollards at various levels depending on the fluctuations in the local water levels alongside the sheet pile wall. These mooring hooks are positioned one above the other in the trough of a sheet pile on both sides of a vertical ladder. They can be bolted or welded to the sheet pile. Mooring equipment on dolphins comes in the form of bollards mounted on the top or sides.
