ABS completes floating wind turbine study for BSEE

ABS was awarded this study in December 2010 ABS has concluded a study on the technical feasibility of floating wind turbines for the Bureau of Safety and Environmental Enforcement (BSEE).The goal was to determine how floating structures and moorings would be affected by the strong interactions among the wind turbine rotor, control system, floating platform and mooring/cable system and how different loading events could impact these systems.ABS was awarded this study in December 2010 through the BSEE's Technology Assessment and Research (TA&R) Program. The project included a technical feasibility study of existing floating wind turbines. Study results served as a basis for identifying the critical technical challenges to deploying floating wind turbines on the U.S. Outer Continental Shelf (OCS). The final step of the project was the proposal of a draft design guideline for permitting floating wind turbine deployment on the OCS.Extensive case studies were conducted to evaluate the characteristic load conditions and global responses of three representative design concepts, including a spar-type, a TLP-type and a column-stabilized (semisubmersible-type) floating support structure and their associated stationkeeping systems. Operational and extreme environmental conditions of the East, West and Gulf of Mexico coastal regions on the OCS were applied in all of ...
