A key stage in the construction of Triton Knoll's offshore electrical infrastructure has been completed with the installation of the second offshore substation platform.

Offshore Substation Platform (OSP) East, the last of the two OSPs, was installed by Seaway Strashnov overnight on Monday 15 June, and marks a milestone in the project’s progress towards first power generation next year.

Together with OSP West, which was installed in April, the offshore substation will transmit electricity generated from the project’s 90 wind turbines, all the way to shore along the 50km long sub-sea export cables. The first phase of commissioning of OSP West is almost complete, and will be repeated on OSP East over the next few weeks.

Julian Garnsey, Project Director for Triton Knoll and innogy, said: “This is an important step in ensuring we remain on track, ready for turbine installation and export of first power early next year.

“Amid the challenges of the current climate, the safe completion of these installations is a great achievement, and testament to the teams of contractors and project personnel who have helped make this happen.”

Triton Knoll consists of two 1,200 tonne offshore substation platforms, using Siemens Energy Offshore Transformer Module technology.

Mark Pilling, Managing Director, Transmission Solutions, Siemens Energy Ltd, said: “Installation of both OSPs is a significant milestone in this project. Now this has been completed we can begin commissioning work to get the wind farm ready to connect to the grid to provide the clean, green renewable power needed to reach net zero.”

An initial 25km stretch of export cable has already been installed from the landfall north of Anderby Creek in Lincolnshire, establishing a connection between the onshore and offshore electrical infrastructure for the first time.

Located 32 km off the coast of Lincolnshire in the east of England, Triton Knoll is owned by innogy (59%), J-Power (25%), and Kansai Electric Power (16%) with innogy managing the construction as well as long-term operation and maintenance works, on behalf of its project partners. It is expected to produce first power in 2021. Once fully operational, it will be capable of generating enough renewable energy to power the equivalent of over 800,000 typical UK households.
