Area facts

The DEK Area encompasses several platforms on the western side of the Dutch North Sea sector.

The D15-A platform is a major treatment and compression complex located 195 km from Den Helder on the Dutch coast. It was installed in 1999 at a water depth of 40 metres. The platform accumulates gas from fields in both the Dutch and the British North Sea sectors. It includes a dehydration facility and two gas compressor units. It has space for up to 24 people.

The D15-A platform treats and compresses gas produced by Wingate, a third-party-operated field in the UK sector. Tie-back of the UK/NL cross-border Sillimanite field development is expected in 2020.

In 2009, the E17-A platform was installed closer to the coast, 158 km from Den Helder. This platform also incorporates a dehydration and two compressor units. It can accommodate up to 14 people.

The various satellite platforms in the DEK area are K9ab-A, K9ab-B, K9c-A, K2b-A, K12-B and D18a-A.  The K12-B production complex has served as a test site for carbon capture and storage technology since 2004.

The gas produced in the DEK area is transported via the Noordgastransport offshore pipeline to its processing location in Uithuizen where it is treated before being added to the Dutch national gas transportation network.
