The high speed vessels are primarily designed for short distances services as public transport of passengers and vehicles. The range of high speed, according to the Code of high‐speed vessels begins at 20 knots, which depends on the cruise speed you desire for your vessel; you will have to use the most appropriate type of propellant. In general, in the past 20 years, they have been building...

This paper analyzes the partitioned and monolithic strategies to simulate tightly coupled hidroelastic problems. The seakeeping hydrodynamics solver used is based on a first-order linear time-domain FEM model with forward speed double-body linearization. structural dynamics full 3D corotational shell elements accounting for geometric non-linearity. Both solvers are implemented under same progra...

Achieving optimal efficiency, good performance, and cost-effectiveness is the main challenge in ship design. Using a bulbous bow part of attaining an excellent design to reduce drag dynamic load caused by waves slamming. The commonly determined shape geometric based on laboratory testing or computer optimization. This article compares probability slamming into catamaran NPL hull without with bo...

The fishermen's dependence on fossil fuels is still very high at 95.4% and has not decreased until now. increased fuel price reduced availability make fishermen struggle to fish. IMO (International Maritime Organization) noted that around 277 million tonnes of are consumed by ships with fuels. According an emissions study conducted IMO, 961 CO 2 accounted for 2.5% global emissions. This aims re...

Continued interest in improving air quality in the United States along with renewed interest in the expansion of urban passenger ferry service has created concern about air pollution from ferry vessels. This paper presents a methodology for estimating the air pollution emissions from passenger ferries and the costs of emissions control strategies. The methodology is used to estimate the emissio...

The paper illustrates the main theoretical and computational aspects of an automatic computer based procedure for the parametric shape optimization of a particular unconventional hull typology: that for a catamaran S.W.A.T.H. ship. The goal of the integrated computational procedure is to find the best shape of the submerged hulls of a new U.S.V. (Unmanned Surface Vehicle) S.W.A.T.H. (Small Wate...

This paper details the CFD validation studies carried out as a pre-requisite for multi-fidelity CFD-based design optimization of high-speed passenger-only ferries aimed at reducing far-field wake energy that causes beach erosion. A potential flow code (WARP) and a URANS code (CFDShip) were validated using full-scale measurements of resistance, sinkage, trim, and far-field wake train obtained ov...
