A Mooring System Management Plan (MSMP) is part of the requirements to ensure risks are managed through the safe design and operation of mooring systems

Plan covers all IMO related Circulars and Local (BHP) requirements including, General ship particulars, Mooring lines & equipment, Inspection, maintenance and retirement procedures, end for end policy, Risk management, safety or personnel and human factors.

Ship Design Minimum Breaking Load (sdMBL) is the minimum breaking load of new, dry mooring lines for which a ship's mooring system is designed, to meet OCIMF standard environmental criteria restraint requirements.

OCIMF MEG-4 recommends mooring lines to be replaced when their residual strength reaches 75% of the Ship Design MBL.

In March 2021, Pilbara Ports Authority issued Marine Safety Bulletin 01/2021, regarding Mooring Line and Mooring Systems Management in Port Hedland. According to it, all vessels calling Port Hedland should have Line Management Plan (LMP) or similar, in which, mooring winch brake rendering loads to be set in accordance with the recommendations given OCIMF Mooring Equipment Guidelines as, in certain instances, mooring lines have parted at loads well below their rated minimum breaking load (MBL) and in the absence of any vessel interaction. Above, in conjunction with already applicable BHP Port Hedland Mooring Management Standard, create a clear and requiring legislative regime, as far as Mooring Equipment is concerned, when calling to Port Hedland ports. Moreover, Gap Analysis indicates that Port Hedland ports Mooring regulation covers to the utmost OCIMF MEG4 Requirements.
