The Buzzard field is one of the largest discoveries made in recent years in the UK sector of the North Sea, with an estimated 550 mbbls of recoverable reserves. It is located in the Outer Moray Firth, 100 km northeast of Aberdeen and 55 km from the nearest landfall at Peterhead. It is operated by Nexen Petroleum U.K. Limited.

The field has been developed by a bridge-linked complex made up of three piled steel jackets supporting a Quarters-Utilities (QU) deck, production deck and wellhead deck. It was discovered in May 2001, with development leading to first-oil in early January 2007.

Nexen awarded DNV a contract to provide verification services according to UK offshore regulations and notified body services according to the Pressure Equipment Directive. An extension to this contract has also been awarded to cover 'in-service' verification, carrying DNV's involvement into the operations phase.
