SOFEC is responsible for the design, construction and supply of an external cantilevered bow turret system for a 357,000 dwt FPSO vessel. The OSX-3 FPSO will be utilized within block BM-C-39 of the Campos Basin, offshore Brazil, on the Waikiki Pero Inga fields in 110m water depth.
This SOFEC external turret mooring system is record-breaking in size and provides safe and reliable means of mooring the FPSO on station in the Waikiki Pero Inga fields for the entire service life of the FPSO, in all sea state conditions. The turret is designed for a combination of 17 risers and 9 umbilicals. The riser system must remain undamaged in the 100-year storm.
The SPM system is an external, bow-mounted cantilevered turret designed to allow free weathervaning of the FPSO about the mooring system. In the offloading condition, the mooring system shall, in addition to withstanding loads from the 304,622 dwt FPSO, be capable of withstanding loads imparted by a Suezmax shuttle tanker moored in tandem off the stern of the FPSO.
The SOFEC turret system will be ABS classed.
