Fossil Energy – Installation
This morning, Heerema Marine Contractors safely installed TotalEnergies’ biggest Tyra II topside on the last remaining bare jacket at the Tyra field.
The lift of the 17,000 metric tons heavy process module broke a world record as the heaviest crane lift ever undertaken at sea.
The lift has been prepared for years, and every single step prior to, during, and post lifting has been outlined in a several hundred pages long manual prepared by Heerema Marine Contractors and TotalEnergies.
After the processing module arrived at the Tyra field on October 3, the offshore crew were immediately into action mode and started to remove the sea fastening below the 47-meters-tall module.
The sea fastening helped to ensure a safe and stable journey from Indonesia. Thanks to great weather conditions, the crane drivers got the green light to lift the module into its final position less than 24 hours after its arrival and four days ahead of schedule.
It required a lot of coordination, horsepower, and precision when the crew on Sleipnir had to install the enormous process module. With two enormous crane hooks, the team picked up the process module from the heavy transport vessel GPO Emerald. Afterward, they sailed one nautical mile to the final bare jacket while they raised the module by nine meters to then lower it onto the six legs.
In the coming weeks, the final Tyra II pieces – two bridges and a flare – will be installed. When all connections are welded, the Installation Team will hand over the baton to the TotalEnergies Hook-up and Commissioning team, who will focus on completing and powering up the installed platforms and reconnecting them to the existing North Sea infrastructure.
