DNV Seattle Obtains Accreditation for Noise Testing of Wind Turbines

A2LA has granted DNV’s Seattle office accreditation for acoustic noise testing of wind turbines in accordance with ISO/IEC 17025:2005 * for acoustic noise measurements as per IEC 61400-11 acoustic noise testing standard for wind turbines. Only a handful of organizations worldwide have achieved accreditation in this area, and DNV is the only private company in the U.S. to have successfully completed this evaluation process.

This new accredited service supplements the accredited wind turbine power performance and mechanical loads testing already being conducted by DNV.

“Our accreditation means that we meet both the technical competence requirements and management system requirements that are necessary to consistently deliver technically valid test and measurement results,” says Mark Young, DNV’s manager of Testing and Engineering.

“This represents our long-term commitment to providing the wind industry with value through a combination of quality service and technical depth,” said Robert Poore, Head of DNV’s Seattle office. “We plan to pursue additional accreditation in areas relevant to our work.”

“We can rapidly deploy equipment and trained personnel to make accredited acoustic noise measurements on a site where wind turbine acoustic emissions may be of concern. DNV has provided testing services on hundreds of turbines in the last five years in North America, Brazil, India, China, Australia, Korea, and other locations. In addition to three areas of accredited testing (turbine power performance, mechanical loads, and now acoustic noise measurements), our testing group also offers met tower equipment procurement and installation, custom boom design, special turbine measurements, and other measurement and testing services,” explains Robert Poore.

*) ISO/IEC 17025:2005 is the International Standard for “General requirements for the competence of testing and calibration laboratories”. IEC 61400-11 is the ”International Technical Standard for acoustic noise testing of wind turbines”.
