Available in PDF, EPUB and Kindle. Book excerpt: In the last half-century, high-speed water transportation has developed rapidly. Novel high-performance marine vehicles, such as the air cushion vehicle (ACV), surface effect ship (SES), high-speed monohull craft (MHC), catamaran (CAT), hydrofoil craft (HYC), wave-piercing craft (WPC) and small water area twin hull craft (SWATH) have all developed as concepts, achieving varying degrees of commercial and military success. Prototype ACV and SES have achieved speeds of 100 knots in at calm con- tions; however, the normal cruising speed for commercial operations has remained around 35–50 knots. This is partly due to increased drag in an average coastal s- way where such craft operate services and partly due to limitations of the propulsion systems for such craft. Water jets and water propellers face limitations due to c- itation at high speed, for example. SWATH are designed for reduced motions in a seaway, but the hull form is not a low drag form suitable for high-speed operation. So that seems to lead to a problem – maintain water contact and either water propulsion systems run out of power or craft motions and speed loss are a problem in higher seastates. The only way to higher speed would appear to be to disconnect completely from the water surface. You, the reader, might respond with a question about racing hydroplanes, which manage speeds of above 200 kph. Yes, true, but the power-to-weight ratio is extremely high on such racing machines and not economic if translated into a useful commercial vessel.

Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of shipboard machinery, equipment, and engineering plants are presented in this text prepared for engineering officers. A general description is included of the development of naval ships, ship design and construction, stability and buoyancy, and damage and casualty control. Engineering theories are explained on the background of ship propulsion and steering, lubrication systems, measuring devices, thermodynamics, and energy exchanges. Conventional steam turbine propulsion plants are presented in such units as machinery arrangement, plant layout, piping systems, propulsion boilers and their fittings and controls, steam turbines, and heat transfer apparatus in condensate and feed systems. General principles of diesel, gasoline, and gas turbine engines are also provided. Moreover, nuclear power plants are analyzed in terms of the fission process, reactor control, and naval nuclear power plant. Auxiliary equipment is also described. The text is concluded by a survey of newly developed hull forms, propulsion and steering devices, direct energy conversion systems, combined power plants, central operations systems, and fuel conversion programs. Illustrations for explanation purposes are also given.
