ESBJERG, Denmark — Heerema Marine Contractors’ crane-lift vessel Sleipnir has set down the final topside on a pre-installed jacket at the Tyra gas field in the Danish North Sea.
The 17,000-ton process module installation is said to be the world’s heaviest crane lift undertaken at sea.
After the 47-m tall process module, built by McDermott in Batam Indonesia, reached the field location, the offshore crew started to remove the sea fastening attached for the voyage onboard the GPO Emerald.
Good weather allowed the crane drivers to lift the module into its final position less than 24 hours after its arrival and four days ahead of schedule.
Using Sleipnir’s two crane hooks, the team picked up the process module from the GPO Emerald, with Sleipnir then sailing 1 nautical mile to the jacket while they raised the module by 9 m, followed by lowering onto the six legs.
Over the next few weeks, the final pieces for the Tyra II redevelopment project, the two bridges and a flare will be installed. Once all connections have been welded, the focus will then switch to hookup and commissioning, powering up the installed platforms and reconnecting them to existing offshore infrastructure.
