The North Sea Tyra redevelopment project advanced with the arrival of the three Tyra East wellhead and riser platforms at Tyra field, partner Norwegian Energy Co. ASA (Noreco) said in an Aug. 30 statement.

Earlier this summer HTV (heavy transport vessel) BigRoll Beaufort sailed from the Sembcorp Marine construction yard in Singapore with the three topsides. At Tyra field, the world’s largest crane vessel, Sleipnir, is now in position to lift the three topsides off the vessel and onto the jackets.

The lifting of the topsides will be followed by an installation period scheduled to take place in September.

Progress on the five remaining platforms continues with first gas expected in second-quarter 2023.

The platforms will, in part, replace ageing equipment and sustain output of 60,000 boe/d at Tyra field for the next 25 years. It is expected that Tyra’s transformation will reduce CO2 emissions by 30% and flaring by 90%.

Tyra is the largest gas condensate field in the Danish Sector of the North Sea. Its facilities process more than 90% of gas produced in Denmark, as well as the entire gas production of the Danish Underground Consortium (DUC) comprised of operator TotalEnergies 43.2%; Noreco 36.8%, and Nordsøfonden 20%.
