Vertical ladders
Vertical ladders are mainly required to provide access to mooring facilities and to serve as a means of escape in emergencies. They must continue as far as 1.00 m below the lowest (tidal) water level to be expected.
To make the ladders easy to install and replace, the lowest ladder fixing is in the form of a "plug-in" fixing. The capping is cut back behind the rungs at each ladder recess. in addition, a grab bar (40mm diameter, 30cm above quay level, 55 cm behind face of quay wall) must be fitted to all quay walls not to subject to flooding.
Bollards
Mooring facilities include quayside bollards, recessed bollards for sheet piles and reinforced concrete walls, dolphin bollards, mooring rings, etc. all these items must be designed in a 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 form high-quality grey cast iron or cast steel, with fixings made from grade S 355 J2+N. They can either be bolted or welded to the top of the capping or anchored in a concrete foundation behind the capping. depending on design, they may need to be anchored back into the ground.
Break-off anchorages can be provided to avoid excessive line pull overloading the sheet pile wall; such anchorages are designed for a nominal load.
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 at the sheet pile wall.
Several recessed bollards are fixed in a row, one above the other, on both sides of a ladder. They can be welded or bolted to the sheet pile wall. Bollards can be fitted to the top or side of a dolphin to provide mooring facilities.
