GUIDE FOR BUILDING AND CLASSING BOTTOM-FOUNDED OFFSHORE WIND TURBINE INSTALLATIONS


176-2015 发布历史

Foreword This Guide provides criteria for the design@ construction@ installation and survey of Bottom-Founded Offshore Wind Turbine Installations@ which comprise permanently sited support structures and foundations of offshore wind turbines attached on and supported by the sea floor. The criteria applicable to floating offshore wind turbine installations are provided in the ABS Guide for Building and Classing Floating Offshore Wind Turbine Installations (FOWTI Guide). Requirements for ancillary offshore wind farm installations such as meteorological measuring towers@ accommodation units@ and transformer platforms are not addressed in this Guide. For the requirements for such bottom-founded installations@ refer to the ABS Rules for Building and Classing Offshore Installations This revision incorporates the following changes: ? 1-1/3 ?C A new optional class notion for the Rotor-Nacelle Assembly (RNA) is offered. ? 1-2/9 ?C More specific requirements were added regarding the number of turbines subject to commissioning surveys as well as the scope of commissioning survey. These requirements are adapted from the current FOWTI Guide and are in line with IEC 61400-3. ? 3-6/15 ?C Guidance is provided on how the site assessment should be done with regard to electric network conditions. ? 4-2/3 ?C Further clarification for the return period of the design storms in tropical cyclone prone areas is added. ? 4-2/Table 1 ?C Additional requirements are provided for considering the directionality of wind and wave that may cause misaligned wave and wind conditions. A new design load case (new DLC 8.2) is added to account for possible fatigue damage during the temporary phase. ? Appendix 2 ?C A new Appendix is added detailing the tropical cyclone wind model developed based on the measurements of tropcial cyclone wind in the past 20 years. ? Appendix 3 ?C A new Appendix is added that provides guidance on fatigue analysis of support structures. This Guide becomes effective on the first day of the month of publication. Users are advised to check periodically on the ABS website www.eagle.org to verify that this version of this Guide is the most current. We welcome your feedback. Comments or suggestions can be sent electronically by email to rsd@eagle.org.
