History
The Magnus oilfield was discovered in March 1974 by BP.[1] The discovery was made 2709 m below the seabed in the younger sands of the Late Jurassic by the semi-submersible drilling rig Sedco 703. Similarly to several other fields in the area, the field was named after the Viking saint–Magnus of Orkney. It was announced on 24 January 2017 that BP will sell a 25% share of the field and turn over the operatorship to EnQuest.[2]
Fabrication of the Magnus structure began in 1981 at Highland Fabricators' yard at Nigg Bay in the Cromarty Firth. [3]
