Suzlon Energy Limited (SEL) announced the completion of its worldwide program to strengthen and reinforce all Suzlon blades of the V2 type on its S88 – 2.1 MW turbine fleet.

Instances of blade cracks were first discovered in late 2007 during the operation of some of Suzlon’s S88 wind turbines in the United States. Suzlon responded immediately and launched a detailed root cause analysis and identification process, followed by extensive testing of the solution and a comprehensive retrofit operation to safeguard and enhance 1,251 (or 417 sets) of S88-V2 blades around the world – a commitment of approximately USD 100 million, already provided in FY2008-09.

Said Mr. Andy Cukurs, Chief Executive Officer of Suzlon Wind Energy Corporation: “We are happy to report the completion of the program in September, 2009. In parallel with strengthening the S88-V2 blades, Suzlon also introduced the next-generation S88-V3, which is consistently delivering and exceeding performance standards at wind farms around the world. Speaking on successful completion of the S88 type certification with the modified blade design, about the testing protocol applied Christian Nath, Vice President - Germanischer Lloyd, said: “Analysis that implies the effect of 3-D loading and design was used for the verification of the modified blade design. Testing beyond the normal scope of IEC 61400-23 was applied to prove the design’s feasibility."
