  • Composite is a material composed of two or more component materials to obtain better properties. 3-phase composite is usually added with reinforced fibers and particles. This report presents an experimental study on the bending of some 3-phase composite plates for Vietnam’s shipbuilding industry. The studied composite is made of polyester matrix, glass fiber and titanium dioxide particle (TiO2). The numerical study, in which the interaction between the matrix and particle is taken into account, shows good agreement with the experiment. ...

  • The shipping industry is both special and fascinating. It is special, above all, because of its truly global nature, the huge discrete investments needed, the highly cyclical markets at play, and the unique competitive structure, with many determined players. It is fascinating, above all, because fortunes are made—and lost—at a fast pace, with some of the most risk-willing owners also serving as decision makers. This book is the result of at least seven forces that have shaped my interest in shipping corporations and their strategies. The first is purely personal.

  • Antiquity Simple machines, such as the club and oar (examples of the lever), are prehistoric. More complex engines using human power, animal power, water power, wind power and even steam power date back to antiquity. Human power was focused by the use of simple engines, such as the capstan, windlass or treadmill, and with ropes, pulleys, and block and tackle arrangements; this power was transmitted usually with the forces multiplied and the speed reduced. These were used in cranes and aboard ships in Ancient Greece, as well as in mines, water pumps and siege engines in Ancient Rome.

  • The natural antimicrobial cationic peptide protegrin-1 displays a broad spectrum of antimicrobial activity and rapidly kills pathogens by interacting with their cell membrane. We investigated the structure–activity relation-ships of three protegrin-1 analogues: IB-367 (RGGLCYCRGRFCVCVGR-NH2), BM-1 (RGLCYCRGRFCVCVG-NH2) and BM-2 (RGLCYRPRFV CVG-NH2). Our antimicrobial and antifungal activity studies of these peptides showed that BM-1 was much more active than IB-367 against Gram-positive bacteria and fungi, whereas BM-2 was inactive. ...

  • Brazilian shipbuilding industry, the main representative of this industry in Latin America, has been very active during the 70s and 80s. Afterwards it has experimented a deep decline. The main preserved construction niche was devoted to supply boats for offshore operations. More recently, due to a political decision from the federal government, most of the orders for offshore platforms and large ocean ships have been placed in the national shipyards.

  • Deck seamanship In general, rigging is a large part of deck seamanship.The ship's standing rigging consists of lines, wires, turnbuckles, and other gear supporting and attached to the stacks, the masts, and the topside structure. Running rigging includes the rigging used in hoisting and lowering heavy weights or in positioning and operating movable deck gear.

  • Main technical issues to be resolved before greater implementation of aluminum alloys in ship structures include weld quality since these alloys are more difficult to weld relative to steel and that shipyards typically have limited experience in these alloys. In terms of mechanical properties, aluminum alloys generally exhibit lower fatigue strength when compared to steel. As-welded fatigue properties can be as low as 6 to 7 ksi (Czyryca et al 2006).

  • The fact that electric arc could operate was known for over a 100 years. The first ever underwater welding was carried out by British Admiralty – Dockyard for sealing leaking ship rivets below the water line. Underwater welding is an important tool for underwater fabrication works. In 1946, special waterproof electrodes were developed in Holland by ‘Van der Willingen’. In recent years the number of offshore structures including oil drilling rigs, pipelines, platforms are being installed significantly.

  • The size and principal characteristics of a new ship are determined primarily by its mission or intended service. In addition to basic functional considerations, there are requirements such as stability, low resistance, high propulsive efficiency, and navigational limitations on draft or beam, all of which influence the choice of dimensions and form. Within these and other basic constraints, the ship’s structure must be designed to sustain all of the loads expected to arise in its seagoing environment.

  • A smidgen of science to go with this model. In a traditional airplane all of the lift, is supplied by the wings, but as speed increases this puts more and more stress on the wings, the answer as was determined years ago is to use a “lifting body”. That is a plane or as in this case a space shuttle that maximizes the strength of structure by using the body of the shuttle itself as the wings. It has not been used heavily in the aviation world, due to politics, but it was the only chance for a ship...
