New certification guideline

GL Renewables Certification (GL RC) has published its new “Guideline for the Certification of Offshore Wind Turbines”. It 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.

GL RC'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.

“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. Also the requirements for floating wind turbines in terms of load stability and mooring safety requirements are addressed.

Slowly but surely the floating offshore wind energy sector is becoming more and more important, particularly because of the fact that the number of locations with shallow waters suitable for fixed-bottom foundations is limited. Floating wind is turning into a highly scalable future energy source because the wind resource in deep waters is extensive and offers a significant potential for marine renewable energy development and growth to many countries.

Luxembourg special fund FP Lux Investments is further expanding its wind power portfolio. With the purchase of the Ratiperä wind farm in southwestern Finland, the portfolio of the Wind Infrastructure I sub-fund has grown to 19 wind farms with 94 turbines and an installed capacity of 269 MW. Of this, a volume of 194 MW was acquired in Germany, 31 MW in France and 44 MW in Finland. The deal was advised by the internationally active M&A advisors and asset manager re:cap global investors ag, which manages the entire evaluation and acquisition process of the special fund.

Siemens Gamesa will supply three onshore wind farms in Norway including 70 units of its Onshore OptimaFlex wind turbines. The SWT-DD-130 turbines will each feature a rated capacity of 4.2 MW and a 130 m diameter rotor. All turbines will be installed on steel towers with 125 meter hub heights. The project sites with 15, 18 and 37 units are located in the Bjerkreim and Ha municipalities – approximately 50 km south-east of Stavanger. A 25-year full service agreement with a yield based availability warranty secures the long term performance of the wind farms.
