This paper describes the site installation of a turret moored Floating Production, Storage and Offloading System - FPSO - in 780 meters of water in Campos Basin, offshore Brazil. The FPSO, a 270,000 dwt converted tanker, is the first of a series of two ordered by Petrobras for development of the Marlim Field. An internal bow mounted Turret system, anchored to the seafloor by 8 chain-wire rope-chain combined mooring legs, is used to permanently moor the FPSO in the location while allowing the vessel to freely weathervane. Thirty-five flexible risers, laid in a free-hanging catenary configuration, provide the flow path between the FPSO and the various subsea equipment on the seafloor. This paper describes the installation equipment and procedures employed.
