Computer implementation of an orthotropic plate model for quick estimation of the maximum deflection of stiffened plates
Oct 01, 2006; ... Abstract: Stiffened plates form the backbone of most of a ship's structure. They are, by far, the most commonly used structural elements in a ship, appearing in decks, bottoms, bulkheads and side shells. Stiffened plates are widely used because of their simplicity to fabricate and excellent ...

Genetic algorithm based technique for erection sequence generator in shipbuilding
Oct 01, 2006; ... Abstract: In order to attain soaring heights of production targets in stringent constraints, a computer program based on a genetic algorithm (GA) has been developed. The initial block is considered as a seed or parent and related blocks as children or offspring. The parent-child relation, which ...
Design of warship plates against underwater explosions
Oct 01, 2006; ... Abstract: Design of ship plates against underwater explosion is a mandatory requirement of warship construction. While non-contact underwater explosions of small intensity induce dynamic stresses that die with time, moderate intensity causes permanent or inelastic deformation, and severe ...
A proposed method to evaluate hull girder ultimate strength
Oct 01, 2006; ... Abstract: Hull girder ultimate strength on four ISSC benchmark vessels is analyzed by using proposed simplified formulae, where a computer code NEPTUNE is developed. The moment-curvature curve and the ultimate bending moment at ultimate state are calculated with initial imperfections in the form ...
Technical note Studies on the feasibilities of control of ship roll using fins
Oct 01, 2006; ... Abstract: Consequences of roll motions can degrade the effective performance of a ship in a seaway. Roll motion stability becomes more critical when the moving ship encounters beam seas. Such stability is ensured using the actions of extra fins fitted to hull. Roll motion is controlled if the ...
Triple-hull ships with small water-plane area: Towing test results and some full-scale comparisons
Jul 01, 2006; ... Abstract: A small water-plane area (SWA) ship consists of an above-water platform and one or more hulls, which include an underwater gondola and thin strut(s) crossing the free water surface. Applications of the SWA concept ensure very high seaworthiness, but their relatively large wetted areas ...
Peculiarity of interior design materials for accommodation areas of cruise ships: A state-of-the-art review
Jul 01, 2006; ... Abstract: Interior design materials for accommodation areas of cruise ships can be classified into (a) walls, (b) floors, (c) ceilings, (d) doors and windows, (e) furniture, (f) lighting systems, and (g) decorative elements in large, medium, and small categories, which constitute the interior ...
Validated finite element analysis model of blast wall panels under shock pressure loading
Jul 01, 2006; ... Abstract: A series of field tests was carried out at the BakerRisk test site in San Antonio, TX, on ¼ scale stainless steel blast panels. The panel design was based on a deep trough trapezoidal profile with flexible welded angle connections. The loading applied to the test panel was a shocked ...
An experimental study on the maneuvering characteristics of a twin propeller/twin rudder ship during berthing and unberthing
Jul 01, 2006; ... Abstract The major maneuvering features of a twin propeller/twin rudder ship during berthing and unberthing can be summarized as follows. First, the forward speed of the ship is very low or zero. Second, the operative area is restricted in that the ship is operated in either shallow water or the ...
Optimum structural design of tankers using multi-objective optimization technique
Jul 01, 2006; ... Abstract: While designing a ship's structure, the material cost of hull's weight and the overall cost of construction processes should be minimized considering safety and reliability. In the past, the minimum weight design has focused mainly on reducing material cost and increasing dead weight, ...
