![]() ![]() Waves have a significant height of 7.7 metres. Weather in the area is reportedly poor, with snow flurries and high seas. All 71 crew on board are in good condition, and the position is not considered critical. This unit was on its way to plug a well on Statoil’s Mikkel field. The Byford Dolphin drilling rig has been adrift in the Halten Bank area of the Norwegian Sea since it escaped from a tow at 07.30 today, 22 November. The licensees in Sigyn are ExxonMobil with 40 per cent, Statoil (50) and Norsk Hydro (10). Plans call for Sigyn to come on stream in the first quarter of 2003. Sigyn will be tied back to the Statoil-operated Sleipner East field. Byford Dolphin will remain in block 16/7 until the end of June 2002, reports Torfinn Hellstrand, drilling and well analysis supervisor. If everything goes according to plan the rig will arrive on the Sigyn field on 1 December, whereupon Statoil will drill and complete three production wells on assignment from ExxonMobil. Byford Dolphin is travelling at two-three knots. The work on Mikkel is not so critical and will therefore be carried out later. Weather conditions have been bad on the Halten Bank, and to avoid further delays Statoil decided to reassign the rig to the Sigyn field so as not to hold up the work there. The rig came adrift during the tow in the Norwegian Sea on 22 November. The original plan was to use this drilling rig to plug a well on the Statoil-operated Mikkel field. Yford Dolphin is now heading for the ExxonMobil-operated Sigyn field in the North Sea. H&W have already begun an intense 3 month period of pre-fabrication where new steel sections will be constructed in advance of the rig arrival. The project will also include numerous standard renewal and maintenance scopes of work such as repairs, renewals and refurbishment of pipework, steelwork, anodes, drilling equipment, electrical systems, propulsion machinery and accommodation areas. Last in Belfast during 2004/2005, this Aker-H3 design semi-submersible drilling rig will have several major modifications and upgrades including the fabrication and addition of 2 new columns and 4 buoyancy boxes for stability and deck load improvements, fitting of a new larger blow out preventer (BOP) requiring underdeck stiffening and the fabrication and installation of a new BOP control house and installation of new drill string handling equipment. H&W and Dolphin will implement an integrated project organisation dedicated solely to the successful execution of the project covering the many disciplines, aspects and subcontractors of the scope. Following on the successful completion of its sister rig the Blackford Dolphin in 2014, the Byford Dolphin project is expected to commence early in 2015. The Byford Dolphin accident remains one of the most harrowing diving disasters of all time, with the official report revealing the brave men who lost their lives exploded due to a sudden change in pressure caused by a faulty airlock.Harland and Wolff (“H&W”) has announced it has been awarded the contract award for the dry docking and Renewal / Special Periodic Survey of the Byford Dolphin Mobile Offshore Drilling Unit (“MODU”) by Aberdeen-based Dolphin Drilling Limited (“Dolphin”). On November 5, 1983, five men died in horrific circumstances when an airlock failure caused their bodies to quite literally burst open deep below the surface of the North Sea as they worked on the Frigg Gas Field, the world's largest and deepest offshore gas field. ![]() They might be separated by metres of water but they have one goal - get the job done and get home.īut while staying on the seabed for long periods of time can reduce the divers' chances of falling ill with the bends, there is a lot that can go horribly wrong 508ft beneath the surface. The divers and their highly trained assistants - known as dive tenders - often work intense 16-hour days as hundreds of their colleagues work in comparative safety in the huge, main rig above.
