Wind energy technology outfit SenseWind has completed a demonstration of its Sense Up-Tower system.
The self-erecting nacelle and service system “radically transforms” how next-generation turbines are installed and serviced making wind energy projects “cheaper, quicker and safer”.
Independent analysis has shown that the SenseWind system can cut levelised cost of energy by as much as 12%.
SenseWind has demonstrated the new system, installing a modified Vestas V27 rotor nacelle assembly on a 26-metre high tower at its test site in Northern Ireland.
The predicted growth in demand for wind energy requires the use of super-sized turbines and deployment on more challenging sites, the company said.
Next-generation turbines and more difficult sites make current installation methods uneconomic or impractical, it added.
The SenseWind system transforms the installation of wind turbines for both onshore and offshore projects by eliminating the need for large expensive cranes and crane vessels, said the company.
SenseWind equipment is modular and only requires standard, readily available cranes and vessels. By automating the heavy lifting and positioning at height, it also improves safety, whilst reducing technical and programme risks.
The system has the added benefit that during operation, it can be used in reverse to allow rapid exchange of major components and complete rotor nacelle assemblies. Inspections, repairs and maintenance of blades and towers are also quicker and easier.
SenseWind chief executive Patrick Geraets said: “The team are all extremely pleased with how well the demonstrator performed.
“We can now finally show the wind industry that Sense works and has the potential to solve many of the installation and service problems for very large turbines both on and offshore.
“The tests have also provided us with valuable information as we work to upscale the Sense system for the growing market.”
