Buoy Assisting RWE Wind Farm26/03/2012
|Knowing the environmental conditions around a wind farm is crucial to a wind farm operator. Making wrong decisions from inaccurate or incomplete data can be costly in terms of time, money or, even worse, accidents. In an effort to ensure it receives accurate and consistent wave and ocean current data, RWE Innogy GmbH (Hamburg, Germany) has invested in a TRIAXYS Directional wave and currents buoy. The German energy giant purchased this buoy after a careful, year-long review of available products on the market. The company will deploy the buoy near its Nordsee Ost wind farm project. The buoy may then be redeployed at other RWE wind farm sites in the future.|
One of the key features of this buoy is a dual primary telemetry option. RWE will initially use the buoy in a remote, offshore location that will require satellite telemetry – Iridium in this case – to send data back to key decision-makers. Then, eventually or in the future when needs change, they will have the ability to switch the primary telemetry over to VHF radio. Waves will be measured by the TRIAXYS Directional wave sensor. Ocean currents will be measured by a Nortek 600KHz current profiler. Secondary telemetry and Watchcircle monitoring is available through Inmarsat D+ telemetry. The mooring has been designed for a 30-metre deployment environment.
Deployment will be carried out in the spring of 2012. Terms of the contract are confidential and have not been disclosed.
RWE is one of Europe’s five leading electricity and gas companies. Through its expertise in oil, gas and lignite production, the construction and operation of conventional and renewables-based power plants, commodities trading as well as electricity and gas transmission and sales, the company covers the entire energy value chain. More than 70,000 employees supply about 16 million customers with electricity and nearly 8 million customers with gas via its fully consolidated companies.

How to Use QPS' Qimera to Validate Processed Point Files
QPS Qimera processing software has been released earlier this year. To demonstrate the capabilities, this video shows how to load processed point files into a Qimera Project. It explains what processed point files are; how to specify the coordinate system of the project and the source files; how to create a Dynamic Surface from processed point files and how to change the dynamic surface and adjust the colour map to aid data editing and validation.
