Oil platform
Introduction
An offshore platform(see Fig.3.5) also referred to as an oil platform or oil rig is a large structure with facilities to drill wells and extract and process oil and natural gas and export the products to offshore. Depending on the circumstances, the platform may be fixed to the ocean floor, may consist of an artificial island, or may float. Remote subsea wells may also be connected to a platform by flow lines and by umbilical connections; these subsea solutions may consist of single wells or of a manifold centre for multiple wells.
