Siemens Energy to supply power equipment for North Sea Troll platforms overhaul
Offshore staff
MUNICH, Germany – Aker Solutions has contracted Siemens Energy to provide the electrical transmission, distribution, and power management system (PMS) for the Equinor-operated Troll West electrification project in the Norwegian North Sea.
This will involve replacing existing gas turbine-driven generators and compressors on the Troll B and C semisubmersible platforms with power from shore.
Electrical power will be supplied to Troll B and C through a 40-mi (65-km), 150-MW subsea transmission cable from the Kollsnes natural gas processing plant on the island of Ona.
Equinor estimates the project will reduce carbon emissions by around 500,000 metric tons/yr, (551,156 tons) equivalent to around 1% of Norway’s entire CO2 emissions, and NOx emissions by 1,700 metric tons/yr (1,874 tons).
Siemens Energy’s scope covers supply includes transformers, reactors, and switchgears. Siemens AG, also part of the consortium, will provide static frequency converter systems, large-scale drive trains, and special frequency converters, allowing power to flow bi-directionally for normal and island operation.
The PMS should help maintain a safe balance between power demand and consumption, to safeguard overall grid stability.
Jennifer Hooper, senior vice president, Industrial Applications Solutions for Siemens Energy, said the company’s electrification experience on other offshore platforms operated by Equinor, including Martin Linge, Johan Sverdrup, and Goliat, were key factors in the contract award.
Installation and commissioning of the electrical equipment for Troll West are scheduled for 2022 – 2023.
