FPSO (Floating Production, Storage and Offloading)

Summary

A Floating Production, Storage and Offloading (FPSO) unit is a facility for developing petroleum resources found under the ocean. These resources account for more than one third of the crude oil production today, amid the declining number of new land oil wells being discovered. It has increased the numbers recently due to the high adaptability to the deep-sea environment. FPSO has crude oil production facilities on the deck (frequently called as “Topsides”) and crude oil tanks in the hull, and can move to the any offshore field requiring it to engage in operations.

Features of FPSO Construction

With FPSO, crude oil is produced by separating the water and gas from the well fluid in offshore oil fields. The associated gas produced is partly used for gas turbine power generation on the FPSO and the rest is pressurized with compressors and injected back into the reservoir just like water to enhance the recovery of the crude oil. When there is an offshore pipeline nearby, the gas line is connected to it and the gas is sent to the shore and used at power stations and other facilities. As the platform of an FPSO is a vessel that floats on the sea, the Topsides must be also designed to accommodate the movement of the water, so to speak designing plant on the land heavily vibrating.

The Topsides on board the vessel are assembled in units of independent blocks called modules. This enables their construction to proceed in parallel with the construction or conversion of the hull , thereby reducing the overall FPSO construction schedule. The design should also assume as a prerequisite the distortion that may result when lifting the completed super-heavy modules onto the vessel. Design and construction of Topsides is conducted by exploiting 3D-CAD, while accommodating stiff conditions unique to FPSO projects on a narrow space on the vessel in motion.

Experience

Since 2005, TOYO has been involved in Topsides facilities to be equipped on FPSO which assume the leading roles in offshore oil production. In the FPSO project operated at Stybarrow offshore oil field off the coast of Australia, the Topsides facilities of which TOYO was in charge has been highly commended by MODEC who is the prime contractor. Since the Stybarrow FPSO Project, Toyo has been awarded nine FPSO Topside Projects.
TOYO is striving to secure more orders in the area of offshore oil field development.
