ACCESSORIES
MODU Moorings are typically composed of
rented moorings:
• S tandard sizes of mooring ropes and
chains are used to design a system that
is adequate for the environmental criteria
• Connectors are made using enlarged end
links and specialty shackles
• Polyester ropes are used with thimbles to
maintain suitable D/d bending ratios
• Chain segments are used between the
polyester segments to maintain the
integrity of the polyester rope jacket and
filter barrier when handling the segments
on the deck of the installation vessel

• Polyester rope gives a "softer" mooring system than steel wire rope; and therefore host motions are more compliant and riser friendly.
• Better Vortex Induced Motion (VIM) response to loop currents than Chain-Wire-Chain system.
• Affords smaller SCR departure angles.
• Allows the use of a significantly smaller turret buoy on FPSOs for enhanced safety and project viability.
• Up to 50% reduction in costs compared to conventional catenary mooring system.
• Approximately 80% reduction in wet weight of tension members (i.e. ropes) when converting from Wire to Polyester. The vertical mooring force on the
platform is reduced by 50%. This reduction in wet weight and forces therefore increases usable payload.
• Up to 50% reduction in mooring pre-tension.
• Polyester rope does not corrode and there is no need for corrosion allowances on the diameter of the polyester like there is on chain and wire.
