Equinor has progessed several projects this week offshore Norway and the North Sea.

Subsea7 secures contract for Fram Sør development project

Equinor has awarded Subsea7 an EPCI contract for the Fram Sør development in the Norwegian North Sea, according to a July 17 news release.

The work scope covers subsea structures and flowlines, including 53 km of production, gas lift and water injection lines, and installation of the umbilical system.

It follows a FEED contract issued to Subsea7 early this year that led to finalization of the project’s technical definition.

Subsea7 will perform engineering and project management at its offices in Norway and the UK, with offshore installations planned in 2026, 2027 and 2028.

The Fram Sør area is 10 km to 30 km north of the Troll C platform, 70 km northwest of Bergen, Norway. The development will be connected to existing offshore infrastructure serving Fram and Troll C.

CHC inks helicopter contract to support North Sea fields

In the UK, Equinor has handed CHC Helicopter a three-year support contract for the Mariner and Rosebank fields, according to a July 17 press release.

The current Rosebank field development is 130 km north-west of Shetland, while the producing Mariner field is 150 km east of the Shetland Islands.

CHC will provide sole-use S92 helicopter support for Rosebank over a three-year period, with a second S92 due to join operations next year to meet transport requirements as the project develops.

For the Mariner, CHC will deploy an H175. All aircraft will operate from the company’s Aberdeen base and provide crew transportation services.

Elsewhere in the world, CHC’s Brazil division has been providing similar service to Equinor to and from the Peregrino field offshore Brazil.

BASF, Equinor sign 10-year natural gas supply agreement

Finally, Equinor has signed a long-term strategic agreement to supply Germany’s BASF with up to 23 terawatt hr of natural gas over a ten-year period, starting on Oct. 1, according to a July 18 news release.

This should cover much of BASF’s gas needs in Europe.

“Gas from Norway comes with the lowest emissions from production and transportation,” said Anders Opedal, Equinor’s president and CEO.
