Equinor and its other partners have agreed to advance with the electrification of Troll West, a part of one of the largest oil and gas fields in the Norwegian sector of the North Sea.
The project involves partial electrification of the Troll B platform and full electrification of Troll C.
The partners have already submitted the plan for development and operation to Norway’s Ministry of Petroleum And Energy for approval.
According to Equinor, the electrification will trim carbon dioxide emissions by nearly half a million tonnes annually.
Additionally, nitrogen oxide (NOx) emissions will drop by 1700 tonnes per year.
Overall, the project is estimated to cost around $950m (Nkr7.9bn). It will receive $62.65m (Nkr520m) from the Norwegian NOx fund.
Equinor development and production Norway executive vice-president Kjetil Hove said: “Electrification is essential to successful reduction of the emissions from the Norwegian continental shelf (NCS), and we have ambitious plans for this. The partnership’s decision to electrify Troll B and Troll C will cut emissions substantially.
“The Troll area will deliver enormous volumes of low-emission energy for many decades, adding great value for the companies and for Norway.”
The electrification project, which will involve substantial deliveries of goods and services, is expected to create new jobs.
Aker Solutions has secured a $350m (Nkr2.9bn) engineering, procurement, construction and installation (EPCI) contract to carry out the necessary modifications to enable the Troll B and C topsides to procure power from shore.
Skanska will deliver a new transformer substation, cable trenches and landfall at Kollsnes, while NKT will develop and install a high-voltage subsea cable from Kollsnes to Troll B and from Troll B to Troll C.
The two contracts value $47m (Nkr390m) and $120m (Nkr1bn), respectively.
Equinor operates Troll with 30.6% interest. Other stakeholders are Petoro 56%, Shell 8.1%, Total 3.7 % and ConocoPhillips 1.6%.
Separately, Equinor also announced that the company and its partners will develop Askeladd Vest in the southern Barents Sea.
The investment will be around $390m (Nkr3.2bn).
