Aker Solutions wins Norwegian Sea tie-back contract

The Norwegian energy group will install subsea flowlines and umbilicals to tie back the Iris and Hades fields, now combined in the Berling project, to extend the production life of the semi-submersible platform.

Aker Solutions said this is a sizeable contract that it defines as between Nkr0.5Bn (US$48.1M) and Nkr1.5Bn (US$144.3M) and will begin this year with engineering.

Equinor requires Aker Solutions to undertake engineering, procurement, construction, installation and commissioning with offshore construction set to begin November 2025.

Offshore operations will continue with flowlines, umbilicals and subsea infrastructure installed until December 2027, with gas and condensate production due to start in 2028.

Åsgård B has processing facilities for gas treatment and stabilising oil and condensates, with gas exported through a long-distance pipeline to Europe.

“The expected recoverable reserves are estimated to be around 45M barrels of oil equivalent, consisting mostly of gas,” said Aker Solutions executive vice-president and head of electrification, maintenance and modifications business Paal Eikeseth.

“The tie-backs will enable a significant contribution to energy security in Europe,” he said.
