GL Renewables Certification (GL RC) has published its new “Guideline for the Certification of Offshore Wind Turbines.” This guideline was compiled by GL Renewables Certification in cooperation with its Wind and Marine Energy Committee. The new guideline, which will be unveiled at EWEA 2013, provides a fully integrated design and analysis concept for offshore wind turbines. It considers every aspect of development, from blade tip to foundation and power export cable, while also allowing for offshore type and project certification.
“The updated guideline reflects main developments in the offshore wind industry,” says Andreas Schröter, Managing Director of GL RC. “For example, it considers the increased size of turbines and mitigation of loads using advanced and intelligent control systems. As a consequence, the examination and testing of control systems are now part of the guideline. Furthermore, the new version contains a number of novel analysis methods, for example, considering the effects of cyclic loads for piles under compression and tension. In addition, it addresses requirements for floating wind turbines in terms of load stability and mooring safety requirements.”
The offshore wind energy market is developing fast. Sites there are larger than previous and they are more challenging environments. Therefore, says GL, the industry must remain vigilant and work to standards that keep pace with the rapid developments in technology and practices and enable safe deployment and long term operation. Certification also helps attract investors, and satisfy insurers.
GL Renewables Certification’s guidelines and technical notes are discussed in its Wind and Marine Energy Committee before publication. The Wind and Marine Energy Committee represents relevant wind energy groups. Committee members are drawn from public authorities, wind turbine and component manufacturers, engineering consultants, institutes, universities, technical associations and insurance companies. Guidelines and notes have been issued for onshore and offshore turbines, wind farms, marine energy, offshore risk analyses, training systems, maintenance systems and many further aspects.
