The Tyra project is operated by TotalEnergies with a 43.2 per cent interest with Noreco (36.8 per cent) and Nordsøfonden (20 per cent) as its partners.

Singapore’s Sembcorp Marine completed the fabrication of two wellhead topsides, one riser topside, and two bridges for deployment to TotalEnergies’ redeveloped Tyra field in late July 2021.

Following a month-long journey from Sembcorp Marine’s Admiralty Yard, the topsides arrived in Denmark earlier this week, carried by heavy transport vessel BigRoll Beaufort.

The lifting of all three topsides will be followed by an installation period scheduled to take place during September. Progress on the five remaining platforms continues per schedule to meet the first gas date in 2Q 2023.

A consortium of Actemium Oil & Gas Commissioning and Semco Maritime will be in charge of commissioning services.
