Platforms Removed At Denmark's Tyra Field

Allseas' Pioneering Spirit crane ship has removed the 14,000-metric ton Tyra East and 7,780-mt Tyra West platform topsides from Denmark's largest gas field Tyra as part of a redevelopment programme, one of the project's partners, Norway's Noreco, said on August 7.

Pioneering Spirit, the largest vessel in the world by tonnage, completed the operation in early August, representing the final stage of decommissioning work. They will be dismantled at a yard in Frederikshavn and 95% of materials are expected to be recycled. 

Tyra accounted for 90% of Denmark's gas production until it was shut down in September last year so that a three-year redevelopment programme could begin. Over the years the North Sea field's platforms have been sinking, requiring its operator, the Danish Underground Consortium (DUC), to take action.

DUC, whose members also include France's Total and Denmark's state-owned Nordsofondon, will install new and elevated topsides and 13-metre-high jacket extensions on top of the existing jacket structures. The $3.2bn redevelopment programme will enable a further 200mn barrels of oil equivalent to be recovered, according to Total.

Noreco noted that the project was continuing on schedule despite challenging market conditions.
