An oil platform is a large structure with facilities to extract and process petroleum and natural gas that lie in rock formations beneath the seabed. Many oil platforms will also have facilities to accommodate the workers, although it is also common to have a separate accommodation platform linked by bridge to the production platform. Most commonly, oil platforms engage in activities on the continental shelf, though they can also be used in lakes, inshore waters, and inland seas. Depending on the circumstances, the platform may be fixed to the ocean floor, consist of an artificial island, or float. In some arrangements the main facility may have storage facilities for the processed oil. Remote subsea wells may also be connected to a platform by flow lines and by umbilical connections. These sub-sea facilities may include one or more subsea wells or manifold centres for multiple wells.

Yme is an oil field in the Egersund basin area in the central part of the North Sea. It is located 160 kilometres (99 mi) northeast of the Ekofisk oil field. The water depth is 93 metres (305 ft). The field was discovered in 1987 and was developed by Statoil with production from 1996 to 2001. In 2001 low oil prices led to the abandonment of the field. After the production license was relinquished by Statoil, a new license group led by Talisman Energy was formed to redevelop the field. In 2007 Talisman was granted permission to redevelop the field. The redevelopment was unsuccessful and the newly installed Yme MOPU STOR was abandoned and decommissioned without having entered production. A new attempt called the Yme New Development was launched by the new operator Repsol, which involved reusing the subsea installations already in place. The Yme field began producing again in 2021, marking the first time that a previously abandoned Norwegian oil field has been restarted.
