![]() ![]() December 1994 with the the completion of the third platform producer. The soil conditions at the GBS site consists of an upper 6 to 7 meter thick layer of silty, sandy, very soft to medium clay, with gravel and occasionally cobbles. The initial field development was finalised in. ![]() This map is based on the use of a multibeam echosounder and proved to be very accurate with regards to local details. Contours for each 25 cm of the seabed at the platform location area, is presented on the seabed map shown on Fig. The Draugen oil field sits in about 250 meters of water, and is located around 150 kilometers north of Kristiansund. At the GBS site, the seabed is relatively even, with water depths ranging from 251 to 254 meters. OKEA ASA has signed a letter of intent (LOI) with Aker Solutions for the Draugen electrification project, offshore Norway. Boulders of sizes up to 1 meter in equivalent diameter have been observed. The area is crossed by many ploughmarks from the latest glacial period, and locally, there are areas on the seafloor where boulders and corals occur rather frequently. In general, the seabed conditions at the Draugen area is characterised by a rather uneven seafloor, which is in contrast to all other areas in the Norwegian sector where large platforms have been installed. The Draugen GBS platform was installed in May 1993, andthe subsea structures were installed during the following months. An artistic impression of the field installations is shown on Fig. At the connections between the steel pipes and flexible lines, a pipeline end manifold, PLEM, is installed.Īll of these subsea structures were founded by steel pipe piles. The Norwegian firm said that the project has started up and is slated to be wrapped up in 2026. Owing to the electrification project, its lifetime-extension could result in 20 years of production and value generation, said Aker Solutions. ![]() The oil produced is centrally stored and processed at the GBS, and exported to an offshore loading unit through two large steel pipe lines and flexible risers. The Draugen oil field has been produced since 1993. Oil platform Petroleum Drilling rig Offshore drilling, Platform. In addition, there are two single oil production wells, and one single gas injection well, each protected by separate wellhead protection structures, WPS. Sea Barents Sea Draugen oil field, sea area, map, oil Field, oil Platform png. There are two water injection templates, each housing 5 injection wells. This structure was at time of installation, the tallest concrete structure ever installed.Ī number of different subsea structures are connected to the GBS through flexible flowlines. The heart of the field installations is the concrete Gravity Base Structure, GBS, founded on the seabed at approximately 250 meters depth of water. This area have seabed topography and soil conditions rather unlike those commonly encountered in the North Sea. The SURF scope comprises approximately nine kilometers of pipe-in-pipe flowline and associated structures in water depths of approximately 250 meters, Subsea 7 said. The Draugen field is located west of mid Norway in The Haltenbanken area, and is the first oilfield being developed in this region. The Hasselmus project sits seven kilometers north west of the Draugen platform in the southern Norwegian Sea. ![]()
