Optimisation of an Electric Catamaran in the Early Design Stage

The paper presents a design study for a crew transfer vessel undertaken in the early design stage. The vessel is designed as a catamaran with electric propulsion to meet port requirements. Striving for small battery weight, the key design mission was to reduce resistance as far as possible to improve performance and range of the vessel. For this purpose, a parametric modeling and hydrodynamic optimisation campaign was conducted. A parametric model for the hull was set up in CAESES. Resistance predictions and power requirements were calculated using CFD with FINE/Marine using a simplified propulsor model. The optimisation was accelerated using surrogate models for a coarse optimization search, before employing high-fidelity models for the final search. Potential for further improvement in design details is discussed.
