Combination of design and manufacture abilities along with innovation has historically played a critical role in the shipbuilding industry. Production activities are complex and many linked industries or "cultural district" have frequently emerged in this domain. The crisis, however, is connected to overcapacity and hyper-competition, so the...

The damage stability criteria for both passenger and cargo ships are going to change from 2009, after finalization of a long and engaging harmonization activity at IMO. Especially in the case of passenger ships. the new probabilistic methodology, significantly different from the present deterministic approach, is likely to concur at...

Focus of this paper is the evidence of strong interconnection between safety rules and design process especially for passenger ships. A change in the methodological approach for the safety framework might imply a strong renewal course also of the decision making process during the ship design, keeping in mind its unique peculiarities. After a...

In the field of sailing yacht design, there is a growing interest and application towards solutions for righting moment enhancement, to be exploited when a superior capacity to counter-balance wind effect is required. The typical solution adopted to provide such increase in performance is the use of ballast systems, mainly represented by the...

This paper is concerned about the prediction of vertical motions and added resistance in waves of catamaran and trimaran vehicles by using a three dimensional panel method based on Rankine sources, developed at University of Genoa. The methodology can evaluate...

In the rule making environment it has recently emerged the importance to investigate the ship hull residual strength after damage, besides the residual buoyancy and stability, in order to better appreciate the survivability characteristics of the ship. In fact, the awareness of the actual hull loading condition and the hull residual strength...

The design of warships has always represented the challenging field of naval architecture: compared with the design of cargo ships, it is a demanding task, usually of superior complexity. During the latest decades, the design process has known an intense re-engineering course, characterized by the proposal to embark System Engineering...

In the last decade, in the field of merchant ships, a long harmonization process has taken place at IMO, resulting in the enforcement of the so called probabilistic SOLAS2009 for the residual buoyancy and stability assessment of a ship in a damaged condition. In the warships design process, the probabilistic methodology might represent a...

At an early stage of naval ship acquisition and design process, it is necessary to perform, in a reasonable time, trade-off studies assessing different ship solutions, often identified by very few parameters. A significant topic during this analysis is the dynamic behavior in waves, dependant on both ship features and sea state. Unfortunately...

The SPH (Smoothed Particle Hydrodynamics) technique is a numerical methodology where the fluid is modelled by a number of particles which are followed during their motions from a positional and physical properties point of view. The technique was developed by Gingold and Monaghan (1977) and ndependently by Lucy (1977), initially with...
