Is it possible to upgrade an External Turret Moored FPSO for increase in water depth?

Asked by kendrickfeng 3 years, 8 months ago | 1 Answers

For example, can an External Turret moored FPSO rated for 100 meter water depth be upgraded for 400 meter water depth? Briefly what all modifications (e.g. structural, risers, turret etc) the FPSO will have to undergo?

Theoretically, it can be. But in real practice, I don't think anybody will do it. 100 m to 400 m WD is not a big deal. But modification will cost too much for management to justify. Spread mooring fairlead, chain locker and handling system has to be provided (that means many existing structures have to be removed). Risers have to be re-located to align either Starboard or Port side, which means big change on existing structure, piping, E&I. Also, spread mooring has to take bigger env load, then the hull and topside structure need to be re-checked against it. It may also need some reinforcement. Not recommended !!!
