The Sevan Hummingbird (IMO: 9417103, Port of Registry: Nassau) is a Floating Production, Storage and Offloading platform (FPSO), which is used as a floating production and storage for hydrocarbons.The hydrocarbons are stored in tanks in the hull of the platform and are transported by shuttletankers or by pipe line to onshore refineries. The hull is fitted with machinery, power generators, transformators, electric boards, fire control systems, ballast pumps and cargo pumps.

The main components on deck are living quarters with control rooms, workshop, life vessels, helipad, cranes, on- and offloading system for oil, and anchorwinches.

The FPSO also has a processing plant for hydrocarbons installed on deck. Depending on characteristics of the field, the processing plant has different modules for processing oil, gas, and water.

There is also a power generating module that delivers power to the platforms additional machinery. The processing module has an oil production capacity of 10.000 - 200.000 bbls.

The oil is brought from the reservoir through one or more risers from the wellhead on the sea bed up to the platform. Gas and water is separated from the oil. The gas can be treated in several ways. It can be flared, re-injected into the well or used in the operations of the processing plant. The water is re-injected into the reservoir or released into the ocean after satisfactory cleaning. Injecting sea water into the well may be relevant.

The Sevan Hummingbird left Yantai Raffles Shipyard,China on March 8, 2007. The platform was placed onboard a dry tow vessel and has entered the port of Rotterdam today. She is currently berthed at Keppel Verolme Shipyard, where the installation of the process plant will take place.
