Aker Solutions history within FPSOs started in the early 1980s, with the development of a monohull production platform. This resulted in the first purpose-built FPSO in the North Sea, the Petrojarl 1. This design has successfully operated on several locations on the Norwegian and the UK continental shelves since 1986.
Market leading design
In total, the Tentech™ FPSO design has been chosen for 9 projects in the North Sea region, representing more than 50 per cent of all the purpose-built FPSOs in UK and Norwegian waters.
The latest project is the Skarv FPSO for BP in the Norwegian Sea, with a Tentech 975BP design. Aker Solutions has carried out front-end engineering and design (FEED) for the hull and topside, and the overall system design for the field, as well as detail engineering, procurement and construction management assistance (EPcma) for the topside.
In addition to the Tentech™ FPSO design, new generic FPSO designs have been developed to meet new markets.
Tailored concepts for the North Sea/Canada
Aker Solutions offers generic concepts for FPSOs for the North Sea and Canada, typically aimed at field developments in 100-350 meter water depths, with significant 100 years waves of up to 16-18 m/s. This design features 500 000 -1Mbbls storage capacity, with turret mooring and thruster assisted heading control.
New concept for West of Australia
Aker Solutions is developing a new shipshaped FPSO turret moored design intended for cyclonic conditions West of Australia. This is the 1st permanently
moored FPSO designed to stay on location even in a 10 000 year cyclonic storm. The ongoing FEED includes hull, turret and moorings.
Positioned for the Gulf of Mexico
Aker Solutions’ FPSO concept for the Gulf of Mexico is typically aimed at field developments in 1500 meter water depths, and with extreme hurricane wind
speeds. This design features 900 000-1Mbbls storage capacity, double hull, with turret mooring – either fixed or disconnectable, for abandonment in case
This product development was initiated as a consequence of the trend in the Gulf of Mexico of moving into increasingly deeper water and away from the existing infrastructure of transport pipelines. Our design has been developed in close cooperation with some of the major oil companies, and has been 3rd party concept reviewed by Det norske Veritas (DNV).
Ready for FEEDs in the West of Africa
Aker Solutions’ FPSO concept for the West of Africa is typically aimed at field developments in deep water. This design features 2Mbbls storage capacity and spread mooring, i.e. with a fixed heading with mooring lines attached to port and starboard bow and stern. A turret-moored option has been developed as well.
The vessel has double sides, similar to the North Sea FPSO, but only a single bottom. The main particulars and structural arrangement have been optimised
with respect to steel weight, the main cost driver for a ship hull. At the same time, the hull is flexible with respect to the arrangement of the process facilities. The hull can accommodate a variety of topside alternatives with only minor adjustment to the hull structure.
Floating LNG solutions
Aimed at the global liquefied natural gas market, Aker Solutions offers Tentech™ concepts for floating liquefaction, storage and offloading (FLNG) as well as a floating storage and regassification unit (FSRU). These designs feature turret or spread mooring, with side-by-side or tandem offloading.
