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.

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.
