The work reviews the state of the art of the use of bonded joints in shipbuilding, and describes motivations, features and results of an experimental research program aimed at characterizing actual performances attainable in bonded joints by use of several adhesives, currently available on the market, applied in realistic conditions. Joints...

The study reports the numerical prediction of a fluid-loaded sandwich panel submitted to a transversal point force excitation

In the present work the calibration is presented of a partial safety factor format for the verification of the hull girder in bending conditions. The calibration is performed by means of a second level reliability model, based on a FORM/SORM procedure. All the steps of the calibration process are described, including: choice of the failure...

The longitudinal strength of the hull girder is traditionally verified by linear superposition of still water (static) loads to wave induced (dynamic) loads. Belonging to the former class, gravitational effects are considered always as directed along the plane of symmetry of the ship, as the static equilibrium position corresponds to the ship...

A second-level reliability analysis is carried out on a realistic case study, represented by a 150,000 DWT double-hull tanker on service on a North Europe – Persian Gulf route. The object of the investigation is the longitudinal strength of the hull girder subject to bending loads. The scope of the analysis is to evaluate different stochastic...

A growing attention has been devoted recently to acoustical problems on board of vessels, particularly in connection with the construction of an increasing number of high standard cruise vessels and pleasure crafts. Severe specifications on maximum noise levels on board, in particular in working, living, and resting areas are now common,...

One of the key points for the success in the construction of cruise ships is the enhancement of high standards for passengers comfort on board, especially in the living and resting areas. For this reason, one of the fields on which research in this sector is focused on is the reduction of airborne and structure-borne noise transmitted inside...

In the present paper a comparison is made between full scale measurements and numerical predictions of the dynamic pressures due to sloshing phenomena in the tank of a ship at sea. The full scale measurements were obtained in the ballast tank of a Bulk-Carrier during a crossocean voyage. The motions of the ship were as well measured by means of...
