AllseasPioneering Spirit, the world’s largest construction vessel, has removed the West Alpha and East Alpha structures from the North Sea’s Tyra field and will deliver them for recycling at Frederikshavn, Denmark.

The removal of the jackets concludes Allseas involvement in the Tyra Redevelopment Project. In total, Pioneering Spirit has removed more than 35,000 tonnes of offshore facilities from the field. The redeveloped Tyra II will continue the production of natural gas with 30% less CO2 emissions contributing to the energy security for Denmark and Europe.

2022 saw a record year for Pioneering Spirit. The vessel has lifted and transported approximately 115,000 tonnes of new and decommissioned facilities for the offshore energy industry.

Allseas’ role in the project covered engineering, preparation, removal and transportation to specialist dismantling yards of the complete East Alpha and West Alpha platforms, flare jackets, IPF and monopole.
