Drillship

Drillships (English drillships ) are mobile drilling stations, which make it possible to positions where normal drilling rigs can not be fixed, up to a depth perform drilling of over 10,000 meters.

Through the use of swiveling impellers or bow and stern thrusters and navigation systems - usually complemented by a system for dynamic positioning ( DPS ), with the support of a Differential Global Positioning System ( DGPS) - the ship can maneuver so that it, in spite of currents and waves, about the drill can be maintained in position. Drillships are often used for research purposes.

The world's largest drilling vessels include the 2009 and 2010 put into service in ships of the Enterprise - class of Transocean Ltd.. The 255 meter long and 38 meter wide ships are designed for water depths up to 3657 meters and have a drilling capacity of up to a depth of 12,191 m.
