Offshore investigation works about to launch at Triton Knoll
19th December 2017
THE largest offshore works to date are about to begin on Triton Knoll offshore wind farm.
Sailing from the Humber, three vessels are to be deployed with technical specialists leading a programme of seabed and sub-seafloor investigations.
Fugro GB Marine has been appointed on the £3 million contract, which will involve mapping and testing at the locations of all 90 turbines and the two sub-stations that will make up the 860MW development off the Lincolnshire coast.
The full package of geophysical and geotechnical investigations will involve borehole testing to a depth of up to 50 metres, as well as looking at conditions around the export and inter-array cable locations.
Andy Barwise, Triton Knoll’s principal geotechnical engineer, said: “We’re delighted to be taking our first steps into UK waters so soon after our successful Contracts for Difference bid, and very pleased to have Fugro at helm of this important stage of the project.
“This programme of site investigations will aid our detailed design work, and marks a critical stage in our preparations for offshore construction, currently expected to begin in 2020. These site investigations will be key to the production and installation of the 90 monopile foundations, currently being designed by UK firm Atkins on behalf of main contractor Smulders Sif Steel Foundations JV , and which will support the most powerful and efficient wind turbines currently on the market.”
East Yorkshire’s Precision Marine Survey Ltd will provide guard vessel services for the duration of the works, ensuring the survey areas remain safe and clear at all times.
It is the first major offshore activity since the successful bid into the Government’s subsidy auction in September, and with Innogy in full ownership, having bought-out former joint venture partner Statkraft. There has been a flurry of activity with all preferred suppliers now selected and collaborating towards the delivery.
Tony Hodgson, Oxfordshire-based Fugro’s global product manager for renewables, said: “We are pleased to be involved in this strategically important project. Our delivery of accurate, reliable data will not only support Innogy’s decisions in the development process but will help to ensure the long-term, safe operational performance of this facility.”
As reported, a final investment decision is anticipated next year, with full onshore construction starting shortly after. The team envisages offshore construction commencing in 2020, with first generation by early 2021.
