The mooring piles are designed based on the berthing capacity and the type of wharf structure to ensure safe and convenient operations such as ship docking, berthing, moving, and turning around. The mooring piles consist of the shell, anchor bolt, nut, washer, anchor plate, and core filling material. They are available in cast iron (HT200) and cast steel (ZG230-450) with specifications ranging from 50KN to 2000KN.
Common mooring piles, storm mooring piles, and trial run mooring piles, categorized by their applications.
The center position of the mooring bollard is generally about 0.5 to 0.8 meters from the front line. Too close, it is prone to be hit during ship docking and undocking, and is also unsafe for mooring operations; too far back, it hinders the operation of loading and unloading machinery and may damage the cables. For wharf and ship repair facilities, due to the presence of electrical junction boxes and other equipment at the front, the mooring bollard should be slightly further from the front line, approximately 0.8 to 1.0 meters.
Storm anchors are used to secure ships during storms and are typically located at the rear of the dock. Some ports, due to the rarity of typhoons or ships not being in port to shelter from strong winds, do not have storm anchors. In other ports, to avoid obstructing the operation of loading and unloading machinery, storm anchors are not additionally installed at the rear of the dock. Instead, the size of the regular mooring piles is increased to allow their use during strong winds.
