The revised Guides incorporate lessons learned from a number of European and North American projects. Furthermore, it contains the latest advancements in International Electrotechnical Commission (IEC) specifications for offshore wind turbines, as well as up-to - date industry best practices and customer feedback.
The revised ABS Guide for the Building and Classing of Floating Offshore Wind Turbines (FOWT Guide) and the ABS Guide for the Building and Classing of Bottom-Founded Offshore Wind Turbines (BOWT Guide) both provide additional notations.
The BOWT Guide includes new notations describing the installation's fatigue-life nature.
“As the global market for offshore wind energy continues to grow, ABS has been involved in a range of industry-leading projects. These updated guides bring together all that experience to better support projects at a range of maturity stages, including concept design, prototype demonstration, pre-commercial wind farms and large utility-scale commercial wind farms,” said Matt Tremblay, ABS Senior Vice President, Global Offshore.
The revised FOWT Guide provides new notations that discuss construction fatigue life, site-specific strength requirements, and life extension. Furthermore, new specific requirements are introduced regarding concrete hull structure, design load cases, and survey. Appendices are also added to provide information on the roles of wind spectra and coherence as well as the aspects of tropical cyclone climate.
ABS has also updated its guidance notes on Global Performance Analysis for Floating Offshore Wind Turbines which support the FOWT Guide with performance analysis methodologies, modeling strategies and numerical simulation approaches.
