The Sevan FPSO has all the facilities related to accommodation, utility systems and the process plant located on a “process deck” which is elevated above the main deck. The “topside” process systems are separated from the accommodation and utility areas by the provision of a blast and fire wall. The process facilities for treating and stabilizing the incoming oil and gas are located aft of the fire and blast wall. Gas compression for export or reinjection as well as produced water treatment and reinjection may be includedas a part of the process plant.
The processed crude oil is stored in the cargo tanks for later offloading to shuttle tankers. The process systems are modularized and may be fabricated at different yards and transported and lifted on board for integration and completion.
