Optimization of monopile offshore wind structures

Structural optimization with fatigue and ultimate limit constraints of jacket structures for large offshore wind turbines

“…They optimized an onshore monopile subjected to several buckling constraints by varying the average thickness of the shells, the amount of ring-stiffeners, and the dimensions of the ring-stiffeners using a zeroth order search algorithm. [2] used a genetic algorithm to optimize an offshore monopile tower, achieving reduction of mass by increasing the material grade and varying different structural parameters while enforcing both FLS, ULS and frequency constraints. In their fatigue assessment they calculated damage caused by wind and wave loads uncoupled.…”

Multidisciplinary design optimization of offshore wind turbines for minimum levelized cost of energy

“…Mass is optimized using gradient based optimization algorithm. Thiry et al [2011] used a genetic algorithm to minimize the structural weight of a wind turbine support structure for an offshore application. Haghi et al [2012] used a similar approach, but instead of using a genetic algorithm he used gradient-based optimization.…”

Integrated Multidisciplinary Constrained Optimization of Offshore Support Structures

“…Previous studies show the advantages of the integrated design with either limited design constraints or disciplines [4,5,6,7,8,9,10,11]. The work presented herein addresses some of the shortcomings of the previous works by developing an integrated design method with all the relevant disciplines (structure, aerodynamics, hydrodynamics and soil mechanics) and design constraints (buckling, fatigue damage and natural frequency) involved.…”
