Resistance prediction of medium-speed catamarans using free-surface viscous flow simulations
conference contribution

To promote sustainable sea transportation and to meet raising ecological requirements to reduce the environmental impact, a new class of large fuel efficient medium-speed catamaran ferries is under development . Rising fuel prices and the society's increasing awareness in environmental sustainability raise the demand for highly fuel-efficient vessels (Davidson et al., 2011a,b). As shown in earlier work (Haase et al., 2012), medium-speed catamarans will efficiently operate at Foude numbers of Fr = 0.35, but unfortunately resistance prediction tools lack for twin-hull craft in that particular speed range. Therefore, there is a demand for numerical tools to correctly determine the resistance of such craft independent of speed, hull form and scale.
