Cefas signs major contract for Round 3 windfarm metocean data delivery

Reference: 02-13
22 January 2013

Cefas has signed a major contract with East Anglia Offshore Wind Ltd (EAOW) to provide metocean data that will support the development of the East Anglia Zone in the North Sea.

EAOW is a joint venture owned 50:50 by ScottishPower Renewables and Vattenfall, and has been created for the development of the East Anglia Zone. It is estimated that the 7.2 GW zone has the potential to meet the equivalent electricity needs of 4.6 million homes.

The three-year project will involve the deployment, operation and servicing of directional waverider buoys and seabed "mini-landers" at a number of sites across the East Anglia Zone.

Directional waverider buoys measure wave height, period and direction, while mini-landers acquire current profile, wave, water depth and suspended sediment data.

The combined datasets will thus provide an in-depth oceanographic assessment of the development zone.

Dr Siân Limpenny, Cefas' Offshore Renewable Energy Programme Director, said: "We are pleased to continue working with EAOW to deliver their metocean needs. The science base and monitoring services that Cefas offer have the potential to reduce costs associated with developing the East Anglia Zone and add a wider understanding of the marine environment.

"The offshore renewables sector is strategically important for the development of future energy needs in the UK. The wave data we collect during this project - which will be relayed back to Cefas in near real-time - will also contribute to a national network of wave monitoring stations. This data is then publicly accessible through our WaveNet website."

EAOW Programme Director, Andy Paine, said: "We are delighted to be working with Cefas, who are a locally based East Anglian business and have an internationally recognised reputation and wide-ranging capability in the marine sector. Their multidisciplinary approach will help us refine our design process with the goal of reducing the overall costs associated with our projects."

During 2010/11 Cefas deployed a number of waverider buoys and acoustic wave and current profilers (using mini-landers) to make wave, tide and current measurements in the proposed East Anglia ONE Windfarm area.

Notes to editors

  1. The Centre for Environment, Fisheries & Aquaculture Science (Cefas) is an executive agency of the Department for Environment, Food and Rural Affairs (Defra) and the UK's most diverse applied marine science organisation. It provides evidence-based scientific advice, manages related data and information, and conducts world-class scientific research. It is also engaged in a range of commercial activities in the renewable energy, infrastructure and other marine sectors. For more detail about its range of activities visit www.cefas.defra.gov.uk.
  2. East Anglia Offshore Wind Ltd is the joint-venture company, which is owned 50:50 between ScottishPower Renewables and Vattenfall AB. For more information visit www.eastangliawind.com.
  3. The UK government aims to achieve 15% energy consumption from renewable sources by 2020.
  4. Construction activity for the East Anglia Zone could last 10 years, with operations for each windfarm running for 20+ years. EAOW represents a significant opportunity for the East Anglian region in terms of investment, jobs and economic growth.
  5. The contract covers the collection of metocean data at a number of sites across the East Anglia Zone. The development zone is approximately 6,000km2 - an area that is 10% larger than Norfolk or 15 times the size of the Isle of Wight.
  6. Cefas offers a "whole life-cycle" approach to the marine renewable energy sector. From design through to decommissioning, Cefas advises on the impacts of both individual devices and whole arrays, and supports operational and construction decisions through marine monitoring and reliable forecasting. For more information about Cefas' capabilities, please view our brochure or contact renewable@cefas.co.uk.
  7. Cefas has extensive experience in the deployment, recovery and operation of waverider buoys and acoustic wave and current profilers. In the past 11 years, Cefas has carried out in excess of 150 waverider deployments, which typically are in place at sea for 10-13 months.
  8. On behalf of Defra, the Environment Agency, the Scottish Environment Protection Agency and the Met Office, Cefas operates the WaveNet programme. Waveriders and SmartBuoys are deployed at 21 oceans sites around the UK to give early warning of marine conditions and potential flooding risks. Near real-time marine data and continually updated maps are available on a dedicated section of Cefas' website: www.cefas.defra.gov.uk/wavenet.
