ABS has issued guidance notes to provide direction for the design and analysis of nearshore position mooring systems used for floating structures such as Floating Offshore Liquefied Gas Terminals (FLGTs), Floating Storage and Regasification Units (FSRUs), Floating Production Storage and Offloading installations (FPSOs) and accommodation barges. Nearshore position mooring in these Guidance Notes is intended to provide long term solutions for station keeping for these floating structures.
ABS highlights that these Guidance Notes are applicable to the position mooring system and mooring equipment onboard the floating structures. The design of jetties or similar bottom supported structures used for the mooring of floating structures is generally the responsibility of the Owner.
These structures should be designed in accordance with related industry guidelines and standards, and they should be able to provide required holding capacity to the mooring system.
Safety considerations, such as snap-back should be taken into account in the design. Also, dending fatigue of mooring line components, such as chain and wire rope, should be considered and a mooring load monitoring system or other acceptable monitoring system should be provided for tracking environmental conditions or mooring line tensions.
