NKT has been awarded a contract for the Troll West electrification project of approx. EUR 95 million (approx. DKK 710m) by Equinor Energy AS on behalf of the Troll Unit.

Troll West electrification project includes partial electrification of the Troll B platform and full electrification of Troll C in the North Sea. This means that both platforms’ power demand will be met from shore. The project will help cut emissions on the Norwegian continental shelf substantially.

The order comprises turnkey supply and installation by NKT Victoria of over 110 kilometres of 145 kV high-voltage AC offshore power cable system with three dynamic sections to electrify the Troll West B and C platforms. 

Troll West comprises two floating platforms, Troll B and Troll C, and the turnkey power cable solution from NKT includes dynamic cables that connect the two floating platforms with static offshore power cables at the seabed. The power from shore solution will be connected to the national grid at Kollsnes, northwest of Bergen, Norway.

Dynamic power cables are an important component when transmitting power to and from floating applications. Here, NKT builds on its vast experience since 2010, where the world’s first high-voltage cables for floating applications were installed. During the past years, NKT has provided power cables solutions to connect several floating platforms with power from shore. These include Gjøa, Goliat and Martin Linge, all of them using dynamic power cables.

The power cables will be manufactured in Karlskrona, Sweden, with production starting in 2021 and with commissioning in 2023. By sourcing the power cables from the Karlskrona plant, strategically located close to the North Sea, and installing them with the highly fuel-efficient NKT Victoria the carbon footprint of the entire transportation and installation campaign is kept at a minimum.
