Hamburg/Germany, 25 January 2013 – 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. Every aspect of development from blade tip, to foundation and power export cable is considered, while also allowing for offshore type and project certification.
“The updated guideline reflects the main developments in the offshore wind industry, ” explains Andreas Schröter, Managing Director of GL RC. “For example, it considers the increased size of turbines and mitigation of loads using advanced, 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 taking into consideration the effects of cyclic loads for piles under compression and tension. In addition, the requirements for floating wind turbines in terms of load stability and mooring safety requirements are addressed.”
The offshore wind energy market is developing fast. Turbines, substations and offshore sites are increasing in size and they are being placed in more challenging environments. Therefore, 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 to attract investors, satisfy insurers and can take offshore project development to the next level.
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 the relevant groups in the field of wind energy. The members of the committee 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.
