What is Mooring in Shipping?

Mooring is a procedure to anchor the ship to a fixed or floating element and keep it connected during loading or unloading operations. Safe mooring must withstand several forces, such as wind, the current, the tide and waves.

What is Mooring Load?

Mooring loads often govern the required lateral load capacity of a pier or berth structure. Mooring hardware and equipment are normally rated for a safe working load based upon allowable stresses and/or manufacturer's testing that should not be exceeded.
