The BP operated jack up Sea Gem grew to become well-known on 30 September 1965 discovering the primary oil within the North Sea, off the mouth of the River Humber.
The Sea Gem was initially a 5,600 ton metal barge, transformed to perform as an oil rig by British Petroleum in 1964. The barge mainly consisted of 10 metal legs which made it potential to boost the barge 15 metres (49 ft) over the water’s floor, in addition to a helipad, residing quarters for the crew of 34 and a derrick with related constructions.
In December 1965 the self-elevating drilling barge was positioned roughly 67 kilometres off the coast of Lincolnshire within the UK North Sea. On 27th December 1965, solely two days after celebrating Christmas on the rig, at round 13:45 hours the crew commenced to jack the platform down. This course of concerned reducing the rig onto the floor of the water, with the intention to float it to the brand new website. A short while later, the passing freighter Baltrover witnessed the principle deck lurch then fall in direction of port. The jacking system on two of the rig’s ten legs had apparently failed, inflicting the rig to fall sideways. As the radio hut was among the many tools that fell into the ocean, the rig by no means despatched out an emergency sign.
Most of the crew had been rescued by the Baltrover or by helicopters that had been known as out within the emergency. At that point there was nothing to been seen of the rig apart from one of many legs sticking above the water and a mass of wreckage. Thirteen males had been misplaced on account of the catastrophe. This was the primary drilling tragedy of North Sea.
As a results of a public inquiry into the accident, a number of modifications had been made with the intention to enhance the security of oil rigs, amongst them using a stand-by boat, which might have the ability to assist rescue crews within the occasion of future accidents, and the popularity of an Offshore Installation Manager.
This inquiry concluded metallic fatigue in a part of the suspension system linking the hull to the legs was accountable for the collapse. (Source and Dukes Museum and Wikipedia)
