Abstract
Floating offshore wind turbines (FOWTs) are crucial for achieving net-zero emission targets, particularly in deep-water regions. However, their operation and maintenance (O&M) costs, constituting up to one-third of total costs, present significant challenges. This study evaluates the feasibility of using floating cranes for onsite major component exchange, specifically focusing on turbine generator removal. Using a calibrated Marine Simulator with the FATHOM HYDRO physics engine, we assessed the dynamic responses and operational limits under varying wave conditions using the UMaine VolturnUS-S 15MW platform. The six-stage lifting operation was analysed for different wave periods to determine impacts on nacelle and generator motions and crane tether forces. Results indicate the operation is feasible without major collisions under various wave conditions, though certain periods pose dynamic challenges. This research demonstrates that floating cranes can effectively perform in-situ maintenance for FOWTs, potentially reducing costs and improving offshore wind energy viability
