DELFT, the Netherlands – Allseas’ Pioneering Spirit has completed the single-lift removal of Total’s 14,000-metric ton (15,432-ton) Tyra East Alpha processing platform topsides in the Danish North Sea.
According to Allseas, this is the field’s heaviest topsides, and the lift was executed in just seconds on Aug. 2.
During the two-week campaign, the Pioneering Spirit will lift some 27,000 metric tons (29,762 tons) of steel out of the Tyra gas field and deliver the structures to specialist yards in Denmark and the Netherlands, covering about 2,000 mi (3,219 km) in the process.
Marco Chiozzi, Allseas project lead engineer, said: “This project involves multiple lifts of diverse structures and different weights, but this is the big one. It’s a great feeling when you see all that hard work pay off. A quick 300 mi [483 km] round-trip to Denmark and in a couple of days, we will be back here to do it all again.”
Located 140 mi (225 km) off the coast of Esbjerg, the Tyra facilities have been at the core of Denmark’s energy infrastructure for 30 years. However, the field requires redevelopment due to subsidence of the depleted reservoirs, which has caused the platforms to sink. The project combines the removal and modification of old facilities and installation of new facilities.
Allseas’ scope covers engineering, preparation, removal, transportation, load-in to shore, and disposal of the Tyra East Alpha and Tyra West Alpha topsides and jackets, integrated production facilities, monopile and two flare jacket modules.
