Nortek UK Renewable Energy Symposium a great success!Scientists and Engineers from across Europe gathered last week at the Sheraton Skyline Hotel, London Heathrow, for two days of presentations on the Use of acoustic Doppler measurement technology in the field of offshore renewable Energy.



This year's Renewable Energy Symposium brought together a very large and diverse group of scientists and engineers to discuss two main topics:

  • Wind Farms - Wave, Current and Scour Measurements
  • Tidal Turbines - Measurement of Turbulent and Laminar Flow

The symposium's inaugural presentation by Keith Hensen of Dong Energy, set the scene for the first day of presentations, by outlining the environmental survey needs of the Offshore Wind Farm Operator.

The morning presentations focussed on the occurrence of scour within wind farms; with reviews, related challenges and perceived survey needs being outlined by scientists, field engineers and regulatory advisors. These presentations included key note contributions from HR Wallingford and CEFAS. Sicco Kamminga, Managing Director of Nortek B.V closed the morning session presenting Nortek's, newly acquired, SeaDarq Radar system.

After lunch, the presentations began with Dean Foden (CEFAS) discussing a regulatory viewpoint on potential environmental impacts of wet renewables. The session continued with presentations related to the practical aspects of data gathering. To conclude this session, presentations of Nortek online systems were given with particular reference to the Prolog internal wave processor, presented by Stephen Andre of GEMS and a presentation by Torstein Pedersen of Nortek AS, discussing the advantages and limitations of using acoustic modems for on-line current and wave monitoring.

Wednesday evening saw a change of pace. For the symposium dinner, the delegates were transported to the Carlton Mitre Restaurant overlooking the river Thames at Hampton Court. The occasion proved to be a fantastic success, rounded off by good food and good company!

Thursday was launched in a grand fashion by a quartet of key note speakers, from the University of Edinburgh, GL Garrad Hansan and the European Marine Energy Centre (EMEC). The focal point of their presentations, was their involvement in the ReDapt (Reliable Data Acquisition Platform for Tidal), a project which aims to install and test a 1 MW tidal turbine at the EMEC in Orkney. The intention of ReDapt is that this will deliver detailed environmental and performance information, never before achieved at this scale, in real sea conditions. Nortek is very privileged, to be intimately involved with the supply of various innovative Doppler current profile measuring devices, related to this project.

The rest of the day was dedicated to a whole raft of presentations, ranging from those reporting on own experiences of gathering data in these most difficult of field environments, to practical guidelines on best field deployment practices, onshore current and and wave trials facility and on research into identifying the optimum field spacing of underwater turbines.

Nortek would like to express our sincerest thanks to all speakers for their hard work and to all the delegates, for their enthusiastic contributions. This was a fantastic event which was both informative and valuable in providing a good platform for networking and discussion.

We look forward to attending next year's symposium in the Netherlands!
