Final Tyra-topside lift breaks world record
Esbjerg, 4 October 2022 – Today at 8:27, the biggest Tyra II topside touched safely down on the last remaining bare jacket at the Tyra field. The lift of the 17,000 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 support of more than 260 offshore workers onboard the world’s largest crane vessel Sleipnir lifted what corresponds to the weight of more than two Eiffel Towers. The lift has been prepared for years and every single step prior, during and post lifting has been outlined in a several hundred pages long manual prepared by Heerema Marine Contractors and TotalEnergies.
After the process module arrived at the Tyra field on 3 October, the offshore crew went 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. Afterwards, 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 baton to the 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.
Finally, Tyra II is in place. The team has been preparing this world record lift for years, and it was truly impressive to see how the planning culminated in just six hours when the world’s largest crane vessel Sleipnir helped us to put the enormous new process module into final position. I’m very pleased that we executed this crucial lift ahead of schedule in our new project plan. Only three more lifts to complete and then our new Tyra II will be in its final shape.
says Lars Bo Christiansen, Project Director Deputy for TotalEnergies EP Denmark A/S.
Facts about the installation
- More than 260 people execute the lifting of the process module, two bridges and one flare onboard Sleipnir in October 2022.
- Sleipnir is the world’s largest crane vessel from TotalEnergies’ EPC contractor Heerema Marine Contractors. Sleipnir’s two huge cranes can lift a weight of up to 20,000 tons. The vessel is 220 meters long and 102 meters wide – a size equivalent to approximately 3 football fields.
- Sleipnir has been part of the Tyra removal campaign and helped install the new jackets in September 2020 as well as the remaining new Tyra II modules including the accommodation module, six well head and riser modules, and 4 bridges in September 2021 and April 2022.
Facts on the process module
- The processing module is 47 meters tall, measures a total floor area of 16,300 square meters, and weighs 17,000 metric tons – equivalent to the weight of more than two Eiffel Towers.
- At peak, the process module will be able to process 300 million standard cubic feet gas per day which is coming from both Tyra and five unmanned satellite fields, namely Tyra Southeast, Harald, Valdemar, Svend and Roar.
- The process module is built with high-end materials, and there are sensors on all the critical equipment (e.g. compressors, pumps, heaters) which continuously collect data and will allow the control room operators to monitor the condition and performance of Tyra II around the clock.
- With the use of new technology and modernized working processes, TotalEnergies anticipates that Tyra’s operational efficiency will increase from its current average of around 80% to more than 90% after launching. Electrically driven equipment motors that are fed with power from the gas turbine generators are just one of the contributors to this.
Facts on the Tyra Redevelopment
- TotalEnergies is the operator of the Tyra field on behalf of DUC – a partnership between TotalEnergies (43.2%), Noreco (36.8%) and Nordsøfonden (20%).
- Tyra is Denmark’s largest natural gas field and has been a center for processing and exporting more than 90% of the natural gas produced in the Danish North Sea before its redevelopment.
- A redevelopment of the Tyra field is necessary due to the field’s natural subsidence of the chalk reservoir after many years of production.
- The redevelopment of the Tyra field includes three main elements: decommissioning and recycling of the old Tyra platforms; recycling and extending the current platform legs on six of the platforms with 13 meters, which will have new topsides; a completely new process module and a new accommodation platform
- Once the modernized Tyra II is back on stream, it is expected to deliver 2.8 billion cubic meter gas per year which amounts to 80% of the forecasted Danish gas production.
- Tyra II will secure continued production of natural gas with 30% less CO2 emissions and contribute to energy security in Denmark and Europe.
