About Equinor – Mongstad Refinery

“The first part of the refinery at Mongstad in Nordhordland was opened for operations in 1975. After the facility was expanded in 1989, the process capacity increased from 6.5 to 8 million tonnes of crude oil per year. The 1990s saw the arrival of pipelines from the Troll B and Troll C platforms and from the Kollsnes and Sture land facilities to Mongstad. 

Equinor’s involvement in Mongstad now includes an oil refinery, an NGL processing plant (Vestprosess), a crude oil terminal, a cogeneration plant and the world’s largest technology centre for CO2 capture from flue gas.”


The Mongstad Project was a turnaround project for which we supplied 1 off 42” double offset rubber lined “cargo” butterfly valve to replace the existing heavily corroded valve.   Materials were WCB/ Al.bronze.
