Drillship
Drillships (engl. Drill Ships ) are mobile drilling stations, making it possible to positions at which normal drilling rigs can not be fixed to perform drilling to a depth of about 10,000 meters.
By using swiveling impellers or bow and stern thrusters as well as navigation systems - usually supplemented by a system for dynamic positioning (DPS) with the support of a Differential Global Positioning System (DGPS) - the ship can maneuver in such a way that it can move over , despite the current and swell the drilling site can be held in position. Drill ships are also often used for research purposes.
The world's largest drilling ships include the 2009 and 2010 ships in service enterprise class of Transocean . The ships, which are 255 meters long and 38 meters wide, are designed for water depths of up to 3,658 meters (12,000 feet ) and can reach a drilling depth of 12.2 km. The P10,000 class from GustoMSC is in the same size class .
