Ocean Ranger was a drilling semi-submersible designed and owned by Odeco of New Orleans. Constructed in 1976 by Mitsubishi Heavy Industries in Hiroshima, Japan, the state-of-the-art vessel was accredited for unrestricted ocean operations and designed to resist extraordinarily harsh situations at sea. After drilling off the coast of Alaska, New Jersey and Ireland, Ocean Ranger moved to the Grand Banks, south-east of Newfoundland, in November 1980. In February 1982 the rig was drilling within the Hibernia Oil Field, at about 315 km southeast of St John’s, Newfoundland, with two different semi-submersibles, Sedco 706 and Zapata Ugland. On the night time of the 14 February, a serious Atlantic storm was forecast and the rigs within the Hibernia Field ready for the worsening climate by hanging-off the drillpipe within the effectively and by disconnecting the rigs from the sub-sea stacks. Due to floor difficulties and the velocity at which the storm developed, the crew of Ocean Ranger have been compelled to shear the drillpipe after hanging-off, after which they disconnected the riser within the early night. At about 19:00 native time, the close by Sedco 706 skilled a big rogue wave which broken some objects on deck and brought on the lack of a life raft. Soon after, radio transmissions have been heard from Ocean Ranger, describing a damaged portlight and water within the ballast management room and ballast valves opening and shutting as a consequence of possible quick circuits. 100-knot winds and 65 waves have been reported. At 00:52 hours, on 15th February, a Mayday name was despatched out from the Ocean Ranger, noting a extreme port record to the rig and requesting rapid help. At 01:30 hours, the Ocean Ranger transmitted its final message: “There shall be no additional radio communications from the Ocean Ranger”. In the midnight, within the midst of extreme winter climate, the crew deserted the rig. The rig remained afloat for an additional 90 minutes and sank. All 84 crew members died, regardless of concerted makes an attempt by the crews of a number of standby boats to rescue males from the water. The crew of the Nordetor provide vessel may see our bodies inside a lifeboat, however they have been unable to get well it. The lifeboat floated away and was by no means discovered once more. The our bodies of 22 of the 84 crew have been discovered within the days after the tragedy. All of these recovered had died of drowning and hypothermia. The Canadian Royal Commission recognized elements that performed a task within the sinking and lack of life: the rig had a number of design flaws, the crew didn’t totally perceive what to do within the case of an emergency involving the Ranger’s ballast management system, the lifesaving gear was insufficient, and the crew lacked coaching in its use.
