Equinor lets contract for electrification of Troll B, Troll C
Equinor and partners have let a front-end engineering and design contract (FEED) to Aker Solutions for topside modifications at Troll B and C platforms in the Norwegian North Sea to accommodate power from shore. Detailed plan work to ensure safe execution will occur this year.
The main driver in the electrification project “is to reduce CO2 and NOx emissions from the Troll B and Troll C platforms by using electrical power from Kollsnes and replacing the existing gas turbine driven electricity generators and gas compressors with electrical equipment,” said Geir Tungesvik, Equinor’s senior vice-president for project development.
The electrical system and power cable from shore will be designed to accommodate full electrification for Troll B and Troll C.
"The selected concept for the electrification is full electrification of Troll C and partial electrification of Troll B with a possibility to fully electrify Troll B later," Tungesvik said.
The CO2 reductions is expected to be 450,000 tonnes/year after the project is completed.
Upon final investment decision, expected by yearend, Equinor can exercise an engineering, procurement, construction and installation (EPCI) option that is included in the FEED contract. A separate FEED contract for the onshore civil was previously let to Multiconsult.
Troll A was the first platform on the Norwegian continental shelf to utilize power from shore.
Equinor is operator with 30.58% interest. Partners are Petoro 56%, Norske Shell 8.10%, Total E&P Norge 3.69%, and ConocoPhillips Skandinavia 1.62%.
