Three of the eight anchors used to hold the semisubmersible drilling rig, Bideford Dolphin, broke loose during a storm offshore Norway in the North Sea. The storm had hurricane force winds of 75 mph and waves up to 40 feet. Of the 77 crew members onboard, approximately 60 nonessential personnel are being evacuated. The rig is not in any immediate danger, but it is feared that the
rig might break loose and since the rig does not appear to be in any danger of capsizing essential crew will remain onboard. The rig had drifted about 925 feet off position before the remaining anchor chains picked up the slack. The rig is was about four miles form another offshore installation, however, if it breaks free the winds would carry it away from those units. The Bideford Dolphin is an Aker H-3 designed semisub built in 1975 and upgraded in 1997. The rig is currently under contract to Norsk Hydro working on the Snorre Field.
