LAIDLER HELPS PROVEN ENERGY TO PROVE COMPLIANCE
12/05/2011 Laidler Associates Ltd
In line with its commitment to developing and supplying products that are confirmed as meeting the highest standards for safety and performance, Proven Energy, the UK's largest supplier of small wind turbines, decided that they needed assistance with the self-declaration of their latest P35-2 12.1 kW wind turbine to the new European Machinery Directive. Accordingly, the company engaged leading safety and compliance consultant Laidler Associates, part of the Machinery division of TÃœV SÃœD Product Service, to help with completing the compliance procedure including the preparation of the technical file.As a well established manufacturer of wind turbines, Proven Energy was well aware that it could satisfy the CE marking requirements in relation to its products by self-declaring them for compliance with the EMC, Low Voltage and Machinery Directives. The company decided, however, that due to the changes to the requirements with the new Machinery Directive, it would be prudent to have assistance which would give both them and their end users the highest possible level of confidence.
The product that was of most immediate concern to the company was its new P35-2 turbine, which has a rated power of 10.5 kW and a reference annual energy (RAE) output in excess of 23,000 kWh. These characteristics, combined with its compact construction and economical pricing, make it an ideal choice for use by agricultural landowners, in commercial premises, and in small-scale wind farms.
Its market potential was, therefore, excellent and was still further boosted when the P35-2 became the first small wind turbine to be awarded full certification under the Microgeneration Certification Scheme (MCS). Understandably, Proven Energy was eager to put the P35-2 on sale at the earliest possible date.
By the beginning of 2010, it had the compliance work associated with the Low Voltage and EMC Directives in place but, for the Machinery Directive, things were a little more complicated. This was because a new version (2006/42/EC) of the Machinery Directive came into force late in December 2009. As no transition period between this and the previous version of the Machinery Directive was allowed, it was essential for Proven Energy to be sure that its P35-2 wind turbine complied fully with the new version.
While product testing for the P35-2 had been completed, Proven Energy knew that the new version of the Machinery Directive introduced significant changes, not least in the area of documentation. To avoid delay in bringing its product to market, it decided to engage the services of an expert to verify compliance. The company's choice was Laidler Associates, which it selected on the basis of proven track record and excellent reputation in handling projects of this type.
Laidler Associates undertook a comprehensive review of the materials relating to the compliance of the P35-2 wind turbine with the Machinery Directive and did indeed identify a number of shortcomings. Although these were far from major, they would undoubtedly have hindered compliance.
"Laidler Associates was not only very responsive, it was also clear that the company had a deep understanding of how the requirements of the regulations implementing the Machinery Directive related to our product," said Jonathan Nowill, Engineering Director of Proven Energy. "But what was really impressive was the report that Laidler Associates produced for us. This included a detailed "to do" list that laid out very clearly the exact steps we needed to take to ensure compliance. The list was easy to follow, and undoubtedly saved us a lot of time and trouble."
As an example of the type of issue identified by Laidler Associates, the user manual was found to contain insufficient information on foreseen ways in which the wind turbine might be used or misused. This shortcoming, and the others highlighted in the Laidler Associates report, were quickly remedied.
"Having carried out the work recommended by Laidler Associates, and organised our compliance documentation in the way that the company suggested, we can have total confidence that the P35-2 satisfies the requirements of the latest version of the Machinery Directive," said Jonathan Nowill. "Naturally, this is very important for us but it's also important for our customers - they don't have to take our word for it that our products meet all of the relevant standards, as this has now been independently confirmed."
A further endorsement of the work carried out by Laidler Associates for Proven Energy was recently provided by the Health and Safety Executive (HSE).
"As part of discussions we were having with the HSE, we presented our compliance documentation," said Jonathan Nowill, "and we were delighted when the HSE team told us that they were very satisfied with it both in terms of content and clarity. That's exactly the sort of response we like to get, especially from a government body! There's no doubt that Laidler Associates played a big role in helping us to reach this position and I have to conclude by noting that the very modest amount we spent on the company's services was money well invested!"
