Experimental investigation and welding modelling of improved fatigue TMCP steels for Offshore Wind Turbine (OWT) support structures

With offshore wind deployment accelerating, thick-section steel structures must be reliable, weldable, and economically manufactured. Thermo-mechanically controlled processed (TMCP) steels, such as S355ML, are widely adopted for offshore wind turbine (OWT) support structures (e.g., monopiles and transition pieces) because they combine high strength ...
