Nothing less than a world record was achieved this morning on the Tyra field. The process platform, which arrived from Indonesia yesterday afternoon, was lifted into place this morning at 8:27 am. The 17,000-ton lift is the heaviest crane lift ever carried out offshore. TotalEnergies writes in a press release.
Nothing was left to chance either, as the two crane operators, with the help of more than 260 offshore workers on board the world's largest crane vessel, Sleipnir, lifted what is equivalent to the weight of more than two Eiffel Towers. The crane lift has been years in the making, with every step before, during and after the operation described in a manual spanning hundreds of pages, prepared by Heerema Marine Contractors and TotalEnergies.
After the process platform arrived at the Tyra field on October 3, the offshore crew immediately got to work, removing the lashings beneath the 47-meter-high platform, which has helped ensure a safe and stable journey from Indonesia. Thanks to good weather conditions, the crane operators were given the green light to lift the platform into its final position less than 24 hours after arrival and four days ahead of schedule.
It took a lot of coordination, horsepower and precision for the crew of the Sleipnir to install the enormous process platform. Using two crane hooks, the team lifted the process platform into the air from the heavy transport vessel GPO Emerald. Afterwards, they raised it nine meters and sailed one nautical mile to the final leg to lower it onto it.
In the coming weeks, the final Tyra II pieces in the form of two bridges and a flare tower will be installed. Once everything is welded together, the installation team will pass the baton to the Hook-up and Commissioning team, who will focus on completing and powering the installed platforms and connecting them to the existing infrastructure in the North Sea.
When operational, the processing platform will be able to process 300 million standard cubic feet of gas per day. The gas comes from both Tyra and the five unmanned satellite fields Tyra Southeast, Harald, Valdemar, Svend and Roar.
