US oil giant Chevron has confirmed it will go ahead with the Alder North Sea development after getting approval from the Government to proceed.
The high-pressure, high temperature gas field will produce first gas in 2016 after Chevron and partners ConocoPhillips approved final plans for the development.
“The Alder Field development is an important milestone in support of our strategic plan to profitably grow production,” said Chevron vice chairman George Kirkland.
The project, estimated to cost around $2.4billion (£1.5billion), with Chevron having awarded contracts with OneSubsea and Technip among other companies last year.
The field, around 100 miles of the Scottish coast, was initially discovered in 1975 but its difficult nature meant that proper development has only now been enabled through improvements to technology.
It is set to produce around 110million cubic feet of gas and 14,000 barrels of condensate per day once at peak production, with output being tied back to the Britannia platform 17 miles away.
