Good mooring management requires knowledge of good mooring principles, information about the mooring equipment installed in the ship and proper maintenance of this equipment and good seamanlike tending.
Officers in charge of a line tending and personnel assigned to tend lines should be aware of the capabilities of the equipment installed on their ship. Specification should [...]

Bight- A loop form by doubling back a rope upon itself.
Bitts – Vertical post or bollards mounted in pairs around which a line can be secured.
Bollard- A vertical post to which the eye of a mooring line can be attached.
Breast lines- Mooring lines leading ashore as nearly perpendicular as possible in a ships fore and [...]

Consideration of the principles in 1.4 lead to the following mooring guidelines and these assume that the moored ship maybe exposed to strong winds or current from any direction.
Mooring lines should be arranged as symmetrically as possible about the midship point of the ship.

Elasticity of Lines
Posted by author on May 31st, 2008
The elasticity of mooring line is a measure of its ability to stretch under load. Under a given load an elastic line will stretch more than a stiff line. Elasticity plays an important role in the mooring system for several reasons:
High elasticity can absorb higher dynamic loads. For these reason [...]

Posted by author on May 30th, 2008
A mooring pattern refers to the geometric arrangement of mooring lines between the ship and the berth.
The most efficient line is a lead line for resisting any given environmental load is a line oriented in the same direction as the load. This would imply, that theoretically mooring lines should all be oriented in the direction [...]
