The Draupner platform is a complex consisting of the Draupner S (58°11′19.60″N 2°28′21.6″E / 58.1887778°N 2.472667°E / 58.1887778; 2.472667Coordinates: 58°11′19.60″N 2°28′21.6″E / 58.1887778°N 2.472667°E / 58.1887778; 2.472667 [1]) and E(58°11′19.30″N 2°28′0.00″E / 58.1886944°N 2.4666667°E / 58.1886944; 2.4666667 [1]) riser platforms in the North Sea. It is located in the Norwegian North Sea block 16/11 160 km (99 mi) offshore from Norway. The complex consists of seven risers and two riser platforms standing in 70 m (230 ft) water depth and linked by a bridge. Draupner E is the first major oil platform using jacket-type construction supported on a bucket foundation and suction anchors.[2][3]

The Draupner platform is a key hub for monitoring pressure, volume and quality of gas flows in Norway's offshore gas pipelines. Draupner S was installed in 1984 as part of the Statpipe system. It connects the Statpipe lines from Heimdal and Kårstø for onward transmission to the Ekofisk oil field. In April 1985, first gas was transferred through the platform. Draupner E was installed in 1994 as part of the Europipe I pipeline. Europipe I, Franpipe and Zeepipe II B are connected to the Draupner E, while Statpipe and Zeepipe I are connected to the Draupner S.[4]

The complex is owned by Gassled and operated by Gassco. The technical service provider is Statoil.

On 1 January 1995, a measuring instrument on the Draupner platform detected the first instrument-recorded rogue wave, known as the Draupner wave.[2]

ScienceNordic. …the Draupner E. was the first major oil platform of the jacket-type (with a fixed steel jacket deck) in the world that was bolted to the seabed with bucket foundations instead of piles. ¶Bucket foundations and suction anchors was a new type of anchorage that up till then had only been used on smaller buoys. But come the 1990s, this technology had been tested vigorously and Statoil decided to use it for bigger constructions, such as the Draupner E.
