Enabling design of floating offshore wind energy systems

by Lee, Yong Hoon

Abstract:

Floating offshore wind turbine (FOWT) technologies have been actively developed during past years to harness currently untapped but profound wind energy located at deep water offshore locations. The FOWT systems are complex due to their inherent nature of interacting with various types and levels of environmental effects, including wind, ocean waves, ocean currents, and storms. Designing such a large and complex system involves decision-making activities spanning various interdisciplinary domains and models. Understanding interactions between areas of multiple governing physics enabled by integrated design approaches opens opportunities for unprecedented design innovation via exploring nonobvious design solutions that account for synergetic design couplings. This lecture covers the concept of the FOWT and advanced FOWT design processes based on integrated physical and control system design optimization (also referred to as control co-design, CCD). CCD is an emerging topic in FOWT development primarily to improve both system performance and required cost simultaneously. The lecture will also cover the current challenges in enabling the design of FOWT systems with potential resolutions, including a lack of fully integrated coupled models, high-dimensionality problems, hierarchical computer-human co-design, and formalizing rule-based design practices.
