Allseas’ gigantic heavy-lift vessel Pioneering Spirit has completed work to remove the processing and accommodation topsides and flare jackets of Total’s Tyra platforms in the Danish North Sea.

The work is part of the French company’s $3 billion redevelopment of the Tyra field.

Pioneering Spirit has removed more than 27,000 tonnes of facilities from the field and transported them to specialist yards in Denmark and the Netherlands for recycling.

Tyra is operated by Total for the Danish Underground Consortium (DUC) — a joint venture between Total, Noreco of Norway and the Danish state-owned North Sea Fund.

The field is being revamped due to subsidence of the field’s chalk reservoirs.

The new Tyra development is expected to deliver about 60,000 barrels of oil equivalent per day at peak and enable production of more than 200 million barrels of oil equivalent.

Total acknowledged earlier this year that work on the politically important $3 billion redevelopment of Tyra was facing "challenges" from the Covid-19 pandemic — including the effective closure of one of the yards building the replacement platforms — but the project remains on schedule for start-up in 2022.
