Siemens acts on Bonus collapse with more checks

摘要

Questions remain over who pays for the additional inspections required following the failure of a Bonus turbine at the Danish Paludan Flaks offshore project in November. On 28 November 2015, one of ten Bonus Energy 2.3MW turbines at the 14-year-old Paludan Flaks offshore wind project near the Danish island of Samso suffered a catastrophic failure; the nacelle and blades broke off and fell into the sea. Catastrophic failure is defined as the complete, sudden, often-unexpected breakdown in a machine or other system. This winter, there have been four such events reported across the wind industry. With regular wind-turbine service and maintenance and the possibility of sophisticated condition monitoring, how is such an embarrassing failure - appearing as it seems out of the blue - still possible?
