Equinor lets EPCI contract for Mongstad refinery upgrades

Equinor Energy AS has let a contract to Aker Solutions to upgrade the wastewater treatment plant infrastructure and lower the environmental impact of the Mongstad refinery on the west coast of Norway near Bergen.

The 12-million tonnes/year refinery is closely integrated with an Equinor-owned oil-terminal (MTDA) connected to multiple oilfields in the North Sea. Via 83-km long pipelines, crude oil comes from the offshore installations Troll B and Troll C to the terminal at Mongstad. There is also a separate pipeline for wet gas from the onshore infrastructure Kollsnes and Sture to Mongstad. Since 2019, crude oil from Johan Sverdrup also lands at Mongstad. The refinery also interfaces with crude tankers docked at the port. The refinery has wastewater treatment plant (WWTP) infrastructure designed to treat water from the refinery, offsite sources, and the oil terminal. 

Aker Solutions will be in charge of project management, engineering, procurement, construction and installation work, and commissioning in an EPCIC contract.  

The service provider’s engineering office in Bergen will be the main location for project management, engineering, and procurement work. The company’s Mumbai office will be involved in engineering. Prefabrication and assembly work will be done from the Egersund yard, while the Stord yard will be responsible for providing construction personnel to the Mongstad site. The project will employ over 500 employees at its peak, Aker Solutions said. 

The project will start right away and is expected to be completed in fourth-quarter 2026. 

Aker Solutions values the contract between NOK 2.5 billion and NOK 4.0 billion.
