The wind turbine blade check centre Blaest in Aalborg, Denmark, inaugurated a brand new check rig on 26 September, wherein the centre determined to speculate after coming into an settlement with Siemens Gamesa to check the corporate’s present vary of offshore blades. The primary blade is already being put by means of paces on the brand new check rig and it’s the 115-metre-long B115 blade for the SG 14-236 Direct Drive turbine.
“The brand new check rig performs a key function in absolutely testing the brand new era of our rotor blades. The mannequin below testing belongs to the most important turbine sort we now have ever made. With solely 90 of those offshore wind generators, we might cowl the annual electrical energy consumption of a metropolis the scale of Amsterdam in The Netherlands. Accordingly, entry to massive check amenities is important for our product validation,” stated Peter Fuglsang, Siemens Gamesa’s Head of Know-how Growth Blades.
Blaest’s new check rig can accommodate wind turbine blades of over 120 metres in size.
The check centre says the rig weighs greater than 1,000 tonnes and has superior design options to safe optimised operational effectivity throughout testing, whereas on the similar time lowering important dealing with and lifting operations.
The brand new check rig is partly financed by means of a financial institution mortgage with a assure from the Export and Funding Fund of Denmark (EIFO) and isn’t supported by means of public grants, in keeping with Blaest, which itself operates on a purely business foundation and is collectively owned by Danish Technical College DTU, FORCE Know-how and Det Norske Veritas (DNV).
Blaest’s blade check facility in Aalborg final 12 months additionally began the testing of the 115.5-metre blade for Vestas’ V236-15.0 MW wind turbine as a part of the prototype’s certification course of.
In a press launch on 27 September, the check centre identified that structural testing of blades was a compulsory ingredient in wind turbine certification and sort testing, in addition to that the scale of wind generators and their blades are rising, with blades measuring greater than 100 metres in size already in operation on prototype generators.
Blaest’s Managing Director, Erik Steen Jensen, stated: “Assembly the wants of the market and our prospects is a key driver for our strategic focus. With this new check rig and all our different rigs, we’re effectively ready for the approaching years of operation. We count on to see even longer blades inside some years, and we’re decided additionally to satisfy the testing wants for these blade sizes by additional extending our capability”.
The SG 14-236 Direct Drive (DD) prototype, Siemens Gamesa’s largest-ever wind turbine, was absolutely put in on the Danish Nationwide Check Centre for big wind generators in Østerild in February and produced its first energy the next month.
With 115-metre-long blades, a rotor diameter of 236 metres, a 43,500 m2 swept space, and the turbine’s capability of as much as 15 MW with Energy Enhance, the SG 14-236 DD can produce 30 per cent extra power than its predecessor, the SG 11.0-200 DD, in keeping with Siemens Gamesa.
