OIL company BP has announced the development of two new oil fields, one west of Shetland and the other in the central North Sea.
Named after Scottish mountains both Alligin and Vorlich are expected to come on stream in 2020.
Alligin is a 20 million barrel recoverable oil field in the Schiehallion area, around 140 kilometres west of Shetland, which will be tied back to BP's Glen Lyon floating production, storage and offloading (FSPO) vessel.
The company said on Tuesday that the contract for the development of the Alligin field had been awarded to Subsea7. Offshore activities are expected to get under way next year.
Incoming BP North Sea regional president Ariel Flores said: "Through our Alligin and Vorlich developments we are simplifying and accelerating the stages of delivery to improve project cycle time, reduce costs and, importantly, add new production to our North Sea portfolio.
"These projects follow on from a period of record investment by BP in the North Sea which helped deliver our Quad 204 project last year and will deliver our Clair Ridge project which is planned to start-up later in 2018.
"While not on the same scale as Quad 204 and Clair Ridge, Alligin and Vorlich will lead to significant production gains and further demonstrate BP's commitment to the North Sea."
Operator BP owns half of the Alligin assets with oil company Shell claiming the other 50 per cent. Vorlich is shared between BP (66 per cent) and Ithaca Energy (34 per cent).
