OWI-Lab’s Large climatic test chamber Arctic or desert conditions on demand The wind power industry is rapidly expanding in windy and remote areas where turbines have to work under extreme conditions. Onshore and offshore wind turbines are usually designed to operate in temperatures ranging from -10°C to +40°C, but in locations like Finland, Canada, Mongolia, and other cold climate regions temperatures drop to as low as -40°C. On the other hand, turbines located in hot regions, like some parts of India for example, can be exposed to temperatures of up to 55°C. These hostile weather conditions form a huge challenge to the equipment itself and to maintenance and repair teams. Repairs may have to be postponed because of restricted access caused by weather conditions, clearly impacting on turbine availability and profitability. That is why the industry needs cost-effective, robust, validated components capable of withstanding extreme conditions. In response to this need, OWI-Lab has built a dedicated test facility at the Port of Antwerp featuring a large climatic chamber for wind turbine component testing in a wide range of temperatures. Mechanical, hydraulic and electrical turbine components weighing up to 150 tonnes or more, such as gearboxes, transformers, generators, pitch & yaw systems, etc. can be tested in temperatures ranging from -60°C to +60°C. Typical prototype testing activities in this facility include design verification testing and component validation. Dedicated R&D tests are supported by providing all required auxiliaries such as a flexible set of power supplies (up to 2MVA). To perform cold soak and cold start-up tests of gearboxes, generators and other rotating equipment, a dedicated no-load test bench with 10.000Nm brake away torque has been built.
