Risk-based multi-objective optimisation of a monopile offshore wind turbine support structure
The present work carries out a multi-objective design optimization of a monopile offshore wind turbine support structure. Three objective functions are created related to the minimization of the total construction cost of the monopile support structure, fatigue damage, and permissible stress ratio....
