Captain has undergone a huge Phase II expansion which has increased the 60,000 barrels per day rate to an average plateau rate of 85,000 barrels per day. A new platform was installed to develop the reservoir within the eastern part of the field (Area B). The $500 million Captain Expansion Project was completed within a 25-month schedule.
Captain is located 134km (90 miles) north-east of Aberdeen, in UK block 1 3/22a. It lies in a water depth of 104m (341ft). The Captain field is owned by Texaco North Sea UK Company (85%) and the Korea Captain Company Limited (15%). Final Commissioning and Production from Captain Area A came on-stream in March 1997.
The floating production, storage and offloading vessel (FPSO) is based on a Tentech 700 design and it was built at Astano’s shipyard at El Ferrol, in Spain. The vessel is permanently stationed 1.5km from the WPP.
The vessel is 214.7m in length, 38m in breadth and 24m in depth. It has a displacement of 114,000t and a storage capacity of 550,000bbl. It can accommodate 50 people. The FPSO provides processing for the crude, the water for injection and has the ability to export the product to the shuttle tanker for transportation. It rotates around a central fixed point, the turret, through which the well fluids are brought onboard the vessel.
The field infrastructure comprises a wellhead protector platform, which is connected by a network of pipelines to an FPSO, on which the crude oil is processed and stored. Oil from the field is exported by shuttle tanker, either directly to customers or to the Nigg Bay terminal in the Cromarty Firth. Storage in the terminal will enable a wide range of destinations and sizes of delivery, for worldwide distribution.
