OSLO, Norway – Heerema Marine Contractors has installed two new platform jackets at the Total-operated Tyra gas/condensate field in the Danish North Sea.
These are the first completed facilities for the Tyra Redevelopment project, 225 km (140 mi) west of Esbjerg. Both were built at Dragados Offshore’s yard in Puerto Real, southwest Spain.
The TEG and THE jackets, for Tyra’s new process and accommodation platforms weighed respectively 6,338 and 3,923 t (excluding piles).

According to Total’s partner Noreco, the main focus of the past year offshore had been on protecting suspended wells and wellhead jackets, and decommissioning and removal of the old Tyra modules (performed this summer).
The new wellhead and riser modules are currently under construction in Singapore, the accommodation module in Italy, and the process module in Indonesia.
Tyra’s facilities have processed more than 90% of the gas produced offshore Denmark. The need for redevelopment was due to the impact of seabed subsidence on the platform complex: production has been temporarily shut in since last September.
When full operations resume, the field should deliver peak production of around 60,000 boe/d.
