Intro
The Goliat FPSO is a cylindrical floating production, storage and offloading unit installed on the Goliat field in the Barents Sea, offshore Norway. Designed for oil production with associated gas handling, it entered service in 2016 as one of the world’s northernmost offshore production units. It stores crude onboard and offloads to shuttle tankers while tied to subsea templates.
Field
The Goliat field, located ~85-km northwest of Hammerfest in the Barents Sea, was discovered in 2000 and is developed with a Sevan 1000 FPSO. Reservoirs occur in the Kobbe and Realgrunnen formations, containing oil with associated gas. The development ties back multiple subsea templates to the FPSO, forming the core production system in harsh Arctic conditions.
Facilities
Goliat’s FPSO integrates production processing, storage, and export functions in one vessel. Subsea wells tied to eight templates deliver multiphase fluids to topside processing trains that separate oil, gas, and water. Oil is stabilised and stored in hull tanks with ~950,000-bbl capacity; periodic shuttle tanker offloading is conducted via dedicated offloading systems. Gas may be reinjected for reservoir management or exported depending on infrastructure at the time of operation. The hull’s circular design and winterisation features accommodate harsh Barents Sea conditions. Mooring uses a multi-point spread anchor system, while utility systems include power generation (supplemented by shore-supplied electricity), flare and safety systems, water treatment and injection facilities, and control/monitoring suites. Helideck and accommodation modules support offshore personnel. The FPSO’s electrical and process suites are designed for continuous operation with redundancy and compliance with Arctic operational standards.
