Norwegian energy giant Equinor completed its three-day lift of the Johan Sverdrup platform in the early hours of this morning.
The lift of the two final platform topside, a bridge and flare stack is the heaviest ever performed offshore, Equinor claim.
The two final platform topsides were installed using the heavy lift vessel Pioneering Spirit.
The living quarter topsides were lifted into place this morning in under 72 hours.
Trond Bokn, senior vice president for the Johan Sverdrup project, said: “Now we are in the process of concluding the installation campaign for the first phase of construction of Johan Sverdrup.
“Putting the final building blocks of this gigantic project into place is important to ensure start-up of the field as planned in November this year.”
Equinor said the final bridge connecting the utility and living quarters topside to the rest of the field centre will be installed during “the next possible weather window”.
The project began installation in 2017.
Stale Hanssen, responsible for engineering, installation and commissioning in the Johan Sverdrup project, added: “We have completed the heaviest lift ever performed offshore.
“Over the course of just three days, we have lifted almost 47,000 tonnes into place. And the whole process was completed safely and efficiently, without harm to people or the environment.
“This was all made possible by in-depth planning and, not least, a high level of precision in execution in collaboration with our suppliers and partners.”
