Abstract
The present invention relates to a drilling vessel with drilling tower or drilling mast for drilling in the earth's surface from said vessel, for example for oil or gas. The drilling vessel according to the present invention is characterized by an auxiliary tower or mast placed next to the drilling tower or drilling mast, and a clamp carriage which is fixed so that it is movable between a first position near the drilling tower or drilling mast and a second position near the auxiliary tower or auxiliary mast, said clamp carriage having at least one gripping clamp for clamping the drill string. The presence of an auxiliary tower or auxiliary mast next to the drilling tower or drilling mast means that a substantial time gain can be achieved during the construction and dismantling of the drilling string.
