#mooringlines

Tails or pennants will provide additional elasticity to wire and high modulus mooring lines and reduce the dynamic loads induced in the mooring line by allowing the ship to respond more freely to various combinations of wind, wave and current, as well as to ships passing nearby. Tails will also distribute the loadings more evenly among the various mooring lines. According to MEG4 the Tail Design Break Force (TDBF) should be 125%-130% of the ship design MBL. Tails are generally connected to mooring lines either through the use of mechanical connecting devices (i.e. mooring links and mooring shackles with steel wire ropes) or directly with the use of a cow hitch (with HMPE ropes).

Mooring lines or mooring wires

Mooring lines or mooring wires used to secure a ship at a berth. Mooring lines should be arranged as symmetrically as possible about the midship point of the ship. The mooring line should be able to absorb shocks that are generated by wind or swell. The amount of stretch required is defined by the situation of the vessel is moored. Harbors with good protection require minimal stretch, while mooring in places where you might experience big swells it is important to have good stretch. In this case even extra items may be required such as rubber stretchers.
