Recent advances in Offshore Technology
A whole range of various structures is employed offshore, counting on size and water depth. within the previous couple of years, we have seen pure sea bottom installations with multiphase piping to shore, and no offshore topside structure at all. Shallow water complex, that is characterised by many independent platforms with completely different elements of the process and utilities linked with gangway bridges. Gravity base consists of huge concrete fixed structures placed on the bottom, generally with oil storage cells in a "skirt" that rests on the sea bottom. an FPSO(Floating Production, Storage and Offloading) is typically a tanker type hull or barge, usually converted from an existing petroleum tanker (VLCC or ULCC). due to the increasing sea depth for new fields, they dominate new offshore field development at over a hundred meters water depth. The tendons are made as hollow high tensile strength steel pipes that carry the spare buoyancy of the structure and ensure limited vertical motion. Semi-submersible platforms, SPAR, Subsea production system.
