Mooring hawsers
When selecting hawsers, terminal operators should take into account not only strength but also energy absorption and fatigue performance. Detailed information can be found in the OCIMF 2000 ‘Guidelines for the Purchasing and Testing of SPM Hawsers’.
Chafe chains
Each mooring hawser should terminate at its shipboard end with a chafe chain.
Weak links
Weak links, if fitted, should be selected such that the recommended bow chain stopper, chafe chain, hawser or connection to the SPM do not constitute the weakest yield strength of MBL component of the entire system.
Support buoys
When the berth is unoccupied, each chafe chain may be supported by flotation devices: a swivel ended type support buoy or a type chain support buoy.
Pick-up / messenger rope
The pick-up rope is connected to the ship end of the chafe chain and typically consists of 150 metres of floating rope (generally polypropylene based) complete with an eye at each end.
