Equinor has received safety consent from Norwegian offshore safety agency Petroleum Safety Authority (PSA) to use the Deepsea Atlantic rig on the Gullfaks field located offshore Norway.
Discovered in 1978, the Gullfaks field lies in the Tampen area in the northern part of the North Sea in water depths between 130m and 220m.
The field is located in production licence 050.
According to PSA, drilling operations on the field are scheduled to last for 72 days.
Equinor operates the field with a 51% stake. Petoro and OMV respectively own 30% and 19% stakes.
The plan for development and operation (PDO) for Gullfaks Phase I was approved in 1981 while Gullfaks Phase II was approved in 1985.
The Deepsea Atlantic is a sixth-generation deepwater and harsh environment semi-submersible rig, which is capable of operating at water depths of up to 3,000m.
Fully owned by Odfjell Drilling, the rig is equipped with an advanced dual derrick and full conventional mooring spread for operations in water depths of 70m to 500m.
In January 2019, Equinor submitted an amended plan to the Norwegian Petroleum Directorate (NPD) on behalf of the licence partners for development and operation (PDO) to improve oil recovery from the Gullfaks field.
In June, Equinor received regulatory approval from PSA to drill a pilot hole in block 34/7 in the North Sea offshore Norway.
In January, Equinor announced plans to reduce greenhouse gas (GHG) emissions generated at offshore fields and onshore plants in Norway.
