LIFTING & DECK EQUIPMENT
Heerema Installs Tyra TEG Module in ‘Heaviest Offshore Crane Lift Ever’
into its final position less than 24 hours after its arrival and four days ahead of schedule.
Heerema said that the process 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 metres to then lower it onto the six legs.
Dutch offshore installation firm Heerema Marine Contractors said Tuesday it had broken a world lifting record with the installation of a 17,000 metric ton TotalEnergies’ Tyra TEG module in the Danish sector of the North Sea.
The TEG module, described as the biggest Tyra II project topside, was installed on the last remaining bare jacket at the Tyra offshore 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. Nothing was left to chance when the two crane drivers, with the support of more than 260 offshore workers onboard Sleipnir, lifted what corresponds to the weight of around two Eiffel Towers.” Heerema Marine Contractors said.
According to Heerema, 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 immediately went into action mode and started to remove the sea fastening below the 47-metre-tall module.
The sea fastening helped to ensure a safe and stable journey from Indonesia.
Per Heerema, thanks to great weather conditions, the crane drivers got the green light to lift the module
In the coming weeks, the final Tyra II pieces – two bridges and a flare – will be installed.
When all connections are welded, the Heerema 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.
