The huge jackup drilling rig Prospector 1 was towed into the Port of Sheerness in Kent, southeast England from the North Sea on Saturday (May 16). <br /><br />The drilling rig will be out of action for around six months. <br /><br />It will be joined by another rig, Prospector 5, in August. <br /><br />Prospector 1 is part of the Borr Drilling fleet and was built in 2013 at a cost of around $200 million. Its height is almost 775ft. <br /><br />The Energy Voice website reported that the company is temporarily laying up the two rigs, because it has “not been successful in securing future work” for them.
