Mooring operation is one of the important tasks that seafarers have to perform on ship's deck.
Technically, the operation may seem simple but there are several dangerous associated with it.
As a seafarer, you must have heard about “Death Traps” on ships and how crew members have lost lives during mooring operation.
Mooring lines
Lines or cables used to secure a ship at a berth.
Mooring lines should be arranged as symmetrically as possible about the midship point of the ship.

- Breast lines – Mooring lines leading ashore as perpendicular as possible to the ship fore and aft line.
Breast lines restrain the ship in one direction (off the berth).
Note: Due to collision with shore gantry cranes, breast lines are not used in container terminals.

- Head lines – Mooring lines leading ashore from the fore end or forecastle of a ship, often at an angle of about 45 degrees to the fore and aft line.
- Spring lines – Mooring lines leading in a nearly fore and aft direction, the purpose of which is to prevent longitudinal movement (surge) of the ship while in berth. Spring lines restrain the ship in two directions: headsprings prevent forward motion and backsprings aft motion.
- Stern lines – Mooring lines leading ashore from the after end or poop of a ship, often at an angle of about 45 degrees to the fore and aft line.
