Floating structure

Abstract

The invention relates to a Floating Production Storage and Offloading, FPSO-, or Floating Production Storage, FSO-, structure comprising a hull adapted to support a weight of at least 50.000 tons, preferably at least 70.000 tons, with sidewalls of a length L extending in a longitudinal direction, a bottom structure and an upper deck, the hull having a breadth B, a process unit support structure overlying the upper deck, hydrocarbon processing units mounted on the process unit support structure, an outer part of the hull comprising: side spaces being bounded by the bottom structure, the upper deck, a respective side wall and an adjacent longitudinal sidewall, the adjacent longitudinal sidewalls being situated at a distance Wt from the side walls, Wt being at least equal to the smallest of 0.2B or 11.5 m, an inner part of the hull comprising: at least one hydrocarbon storage tank for storage of hydrocarbons being situated between the bottom structure, the upper deck and the adjacent longitudinal walls, wherein the vessel comprises a centre line bulkhead and, between one and four hydrocarbon storage tanks of substantially the same size extending, in a transverse direction, between an adjacent longitudinal sidewall and the centreline bulkhead.
