Seakeeping Analysis of Two Medium-speed Twin-hull Models

The use of twin-hull ships for high-speed passenger and car-passenger transportation is widespread, whereas their potential use for high-speed cargo transportation was estimated as limited. The present article discusses the seakeeping performance of two twin-hull models of an innovative medium-speed container ship design. Their hull form was the result of a thorough hydrodynamic optimization performed at the School of Naval Architecture and Marine Engineering of NTUA aiming to minimize the calm water resistance within the EU-funded project “EU-CargoXpress.” The seakeeping analysis was performed by applying numerical tools and also by performing a series of experiments in the towing tank of NTUA and MARINTEK. The obtained results are presented and discussed.
