A DRILLING VESSEL AND A METHOD MAKING USE OF SAID DRILLING VESSEL

摘要

The invention relates to a drilling vessel for drilling in the earth's surface, comprising a dual firing line and a suspension carriage to move strings of drilling tubulars between the two firing lines, wherein the suspension carriage is provided with a stationary first suspension device and a moveable second suspension device, so that the second suspension device only requires a relatively small sideways motion in order to pass a string of drilling tubulars present in a firing line and to allow the first suspension device to approach and engage said string of drilling tubulars. The invention further relates to a method for replacing a string of drilling tubulars for another string of drilling tubulars in which use is made of a drilling vessel according to the invention.
