FPSO Turret Design Change

FPSO Turret Design Change

It is becoming more and more common for FPSO and semi-sub operators to uprate their mooring chain from say R4 to R5 chain.
We will undertake design checks to ensure that all the structural components in the load path are strong enough to accept the higher loads and be acceptable to ship’s Class Rules.
The components we check are -
Anchor winch foundations
Turret structure (or semi-sub columns)
Turret bottom and fairleader sockets (or semi-sub fairleader foundations)
Fairleaders and gypsy’s
