Statoil expects to start production from Mariner in 2017, pending final approval by the UK authorities.
More than 700 jobs will be created, including 200 onshore posts in Aberdeen.
The field is expected to produce for 30 years, with average production of about 55,000 barrels of oil a day from 2017 to 2020.
The Mariner Field is located on the East Shetland Platform of the UK North Sea, about 150km (93 miles) east of the Shetland Isles.
Statoil is the operator of the field, with 65.11% equity. Other partners include JX Nippon Exploration and Production (UK) Limited (28.89%) and Cairn Energy (6%).
The development concept includes a production, drilling and quarters (PDQ) platform based on a steel jacket, with a floating storage unit (FSU).
More than 140 reservoir targets are planned for Mariner.

Industry body Oil and Gas UK welcomed Statoil's announcement.
Economics director Mike Tholen said: "The largest offshore development in the UK for a decade, Mariner requires pioneering technology and will bring hundreds of high-skilled, long-lasting jobs across the country, hundreds of millions of pounds in additional tax revenues, as well as crucial security to our energy supplies.
"Expected to produce oil and gas for 30 years, this project - and others recently given the go-ahead on the UK continental shelf - will help to boost production and stem the decline we have seen in recent years, so helping the full economic benefit of our reserves to be realised in time."
