ESBJERG, Norway — The Tyra II processing module left the McDermott shipyard in Batam, Indonesia, for the redevelopment of Tyra II in the Danish North Sea.
TotalEnergies EP Denmark is leading the project on behalf of its Danish Underground Consortium partners Noreco and Nordsøfonden.
The 18,700 tonne (17,000 metric ton) and 47m high module is on board the GPO Emerald heavy lift ship. The trip to the Danish North Sea should take around 30 days. When crossing the Suez Canal, the ship will have to be ballasted to pass under a bridge with less than 2 m clearance.
Upon reaching the Tyra field, the processing module will be installed as the last of the eight platforms of the upgraded Tyra II gas production complex and will be placed on the jacket by Heerema Marine Contractor’s Sleepnir crane boat.
In the field centre, work continues to power the installed platforms and reconnect them to the existing North Sea infrastructure.
Construction of the 16,300 m² treatment module began in October 2018. It comprises 19 rooms including an air compressor room, workshops and an Uninterruptible Power Supply room, with a total of 783 km of cables.
Sensors on all critical equipment (compressors, pumps, heaters) will continuously collect data, allowing control room operators to continuously monitor the status and performance of Tyra II.
With the adoption of new technologies and more modern work processes, TotalEnergies expects Tyra’s operational efficiency to increase to over 90% once back in service, aided by electrically driven equipment motors. powered by gas turbine generators.
At maximum, the processing module will be capable of processing 300 MMcf/d of gas from Tyra and five unmanned satellite fields, Tyra Southeast, Harald, Valdemar, Svend and Roar.
The redevelopment, following the natural subsidence of the chalk reservoir, involved the dismantling and recycling of the old Tyra platforms; recycle and lengthen the current platform legs on six of the platforms by 13m, with new topsides in each case; a new process module and a new hosting platform.
Tyra II should produce 2.8 bcm per year, or about 80% of the gas production planned in Denmark.
