Triton Knoll selects GeoSea for turbine transport and installation, completing a full house of preferred suppliers

  • GeoSea will install 90 of the market-leading MHI Vesta 9.5MW wind turbine generators (WTGs)
  • Offshore WTG installation likely to start in early 2021
  • UK firms set to play a key role in Triton Knoll’s construction and operation.

Triton Knoll today confirmed GeoSea as its preferred supplier for the transportation and installation of the ground-breaking MHI Vestas V164-9.5 MW turbines at the 860MW East Coast wind farm.

innogy’s Triton Knoll Offshore Wind Farm will be one of the first in the world to install and operate MHI Vestas’ V164-9.5 MW turbines, described by the supplier as the most powerful and efficient on the market.

GeoSea would be due to start work in Q1 2021. Its contract includes the design and manufacture of the sea-fastening and tagline systems, and the transportation and installation of all 90 of the 164metre diameter turbines.

While still at preferred supplier stage, Triton Knoll will continue to work with GeoSea to maximise opportunities for UK businesses, as it works towards the delivery of its target of 50% UK content, throughout the lifetime of the project.

Now, just over a month after its successful bid into the UK Government Contract for Difference auction, Triton Knoll can confirm its full house of preferred suppliers, and is pressing ahead towards a Financial Investment Decision in mid-2018, with onshore works expected to start shortly after.

The full list of preferred suppliers at Triton Knoll Offshore Wind Farm is now:

  1. Siemens Transmission and Distribution Ltd (STDL) – design and manufacture 1 x onshore and 2 x offshore substations. STDL will also install the onshore substation
  2. J Murphy & Sons (JMS) – supply and install the almost 60kms underground onshore cable route
  3. MPI Offshore – transport and install all offshore foundations and two offshore substations
  4. MHI Vestas Offshore Wind – supply 90 of its V164-9.5 MW turbines
  5. NKT and VBMS – supply and install all offshore export and array cables
  6. Sif Netherlands B.V. and Smulders Projects Belgium N.V. – manufacturer monopile foundations for turbines and OSPs
  7. GeoSea – transport and install all 90 wind turbines.

Jon Darling, Triton Knoll senior project manager said: “From the outset, Triton Knoll has worked collaboratively with its supply chain partners, to ensure that the business case we submitted into the Contracts for Difference auction can and will be delivered, effectively from the point of having won a CfD. It’s because of this approach that we’re already able to announce a wealth of preferred suppliers across our entire project, with UK firms playing a strong role in the delivery of the wind farm.”

GeoSea has a strong track record in offshore wind energy projects in the UK, including Westermost Rough, Kentish Flats Extension, Race Bank and Galloper. The offshore installer is expected to commit a high capability/capacity installation vessel to the delivery of the contract.

Jan Klaassen, Business Unit Manager Offshore Renewables at GeoSea, said: “The collaborative approach adopted by Triton Knoll during the tender process together with  GeoSea’s leading position in providing state-of-the-art, integrated solutions for the offshore wind industry, has helped the project deliver a sustainable, low cost of energy.  GeoSea will work alongside Triton Knoll to engage with UK suppliers and to help maximise UK content.”

Triton Knoll is a circa 860MW East Coast offshore wind farm project, and owned by Innogy Renewables UK Ltd (innogy). The project expects to trigger a capital expenditure investment of around £2billion into much needed UK energy infrastructure, which will enable the delivery of some of the lowest cost energy generation for UK consumers.

The project is now progressing towards a financial investment decision likely in 2018 with full onshore construction starting shortly after, and offshore construction starting in 2020. First energy generation could be as early as mid-Q1 2021, with the project expecting to begin commissioning in 2021.

Editors notes

A Snapshot of Triton Knoll statistics:

 

The project will be located approximately 32km off the Lincolnshire coast and 50km off the coast of North Norfolk. It has consent to install almost 60 kilometres of onshore underground export cable, and a new substation near Bicker Fen.

 

  • Likely overall capital expenditure investment in much needed UK energy infrastructure – around £2billion
  • Likely overall UK content – at least 50% (full project lifecycle cost)
  • Potential jobs supported – up to 3000 UK Jobs during construction
  • of turbines – 90 MHI Vestas V164-9.5 MW
  • Installed generating capacity – circa 860MW
  • Homes equivalent – an expected minimum of 800,000
  • Size of turbines (height) – Approximate tip height of V164-9.5 MW turbine – 187m
  • Distance Offshore – 32 km off the coast of Lincolnshire and almost 50km from the coast of North Norfolk
  • Point of Landfall – north of Anderby Creek
  • Connection point to national grid network – existing national grid Bicker Fen substation
  • Length of cable route (onshore & offshore) – onshore corridor = 57km, offshore corridor = 49km (combined distance is approx. the same as London to Southampton.)

CFD award and consents

Triton Knoll was awarded a Contract for Difference on Monday 11 September 2017.

In July 2013, the Secretary of State granted consent for the offshore array element of the project (turbines, offshore substations, inter array cables etc). In September 2016, the Secretary of State also granted a Development Consent Order (DCO) for the Electrical System (ES) which connects the power generated from the offshore array into the national grid onshore. The ES consent includes the offshore export cable, the onshore underground export cable, an intermediate electrical compound at Orby, and a new substation at Bicker Fen, ultimately ensuring the delivery of energy potentially into an anticipated 800,000 UK homes once the wind farm is fully operational.

Energy Generation

It is estimated that the average annual generation expected at the site could be equivalent to the approximate domestic needs of an expected minimum of 800,000 average UK households.

Energy predicted to be generated by the proposal is derived using wind speeds monitored in the local area and correlated with long term reference data. The energy capture predicted and hence derived homes equivalent figure may change as further data are gathered.

Equivalent homes supplied is based on an annual electricity consumption per home of 4100 kWh. This figure is supported by recent domestic electricity consumption data available from The Digest of UK Energy Statistics and household figures from the UK National Statistics Authority.
