Singapore’s Sembcorp Marine has completed the fabrication of two wellhead topsides, one riser topsides and two bridges for TotalEnergies’ Tyra Redevelopment project in the North Sea offshore Denmark, despite the challenges wreaked by the coronavirus and related protocols.

The topsides and bridges, which will replace ageing facilities on the Tyra field, on Sunday sailed away from Sembmarine’s Admiralty Yard.

Unprecedented challenges

Sembmarine admitted that the Covid-19 pandemic had caused “unprecedented challenges” to completion of the modules and bridges.

“In spite of significant supply chain disruptions and acute manpower shortages, the group challenges through operational flexibility, close collaboration with its customer and leveraging its global supply chain and logistics capabilities, to deliver the modules and bridges without compromise to safety and quality,” the contractor said.

Samuel Wong, Sembmarine’s head of offshore platforms, said: “Amid the multitude of challenges brought on by Covid-19, Sembcorp Marine is proud to have completed the structures safely for our customer.

"The topsides are delivered building on our extensive track record in constructing topside modules and other facilities for the offshore, marine and energy industries.”

High-tech centre

The redeveloped Tyra is envisioned to be a high-tech production and natural gas export centre over the next 25 years. It is designed to reduce the environmental footprint and optimise the energy efficiency of its operations.

“The sailaway is a result of the good collaboration between Sembcorp Marine, and our site team at the yard in Singapore,” said vice president, head of the Tyra Redevelopment TotalEnergies EP Denmark, Morten Hesselager Pedersen.

“The Tyra Redevelopment project reaches a key milestone as the topsides are installed later this summer, and we will see the physical contours of Tyra 2, which will be the new high-tech hub for Danish natural gas and reduce CO2 emissions by 30%.”

In December 2019, Sembmarine won a subcontract to build six topsides modules and four bridges for the TotalEnergies’ Tyra Redevelopment project.

The remaining topsides modules and bridges are now expected to be delivered in January 2022.

Tyra may be one of the last projects of its kind in Denmark.

Lawmakers there reached a political agreement in December 2020 to cancel a planned eighth licensing round and any future tenders, while also making 2050 the last year it will extract fossil fuels from the North Sea.

Existing licence holders will be allowed to apply for licences around existing acreage and to continue exploring ahead of the 2050 deadline. New entrants will also be able to make applications for licences.

TotalEnergies is leading the $3 billion development in the Danish sector of the North Sea, where first gas was recently postponed by a year to the second quarter of 2023 after the Covid-19 pandemic took its toll on construction work.

TotalEnergies operates Tyra on behalf of Danish Underground Consortium, comprising TotalEnergies on 43.2%, Noreco on 36.8% and state entity Nordsefonden on 20%.

The topsides will be transported directly to the Tyra field by the heavy transport vessel Bigroll, and the voyage is expected to take approximately one month, targeting an offshore installation window from late August to early September, according to a statement by Noreco, a Norwegian energy company.
