The problem of emission of a single normal wave by a vertical discrete linear array in the Pekeris waveguide is studied. The array aperture is less than the waveguide thickness. The sound energy is emitted into the discrete and continuous spectra. © 2010 Pleiades Publishing, Ltd.

FAST 2013 - 12th International Conference on Fast Sea Transportation | Year: 2013

This paper is a continuation of the series of papers that have been presented since 2005 at previous FAST conferences on the development of the hi-speed catamaran hull form employing semi-elliptical sections, the effect of transom area on smooth water resistance and most recently the comparison of the interference resistance with the University of Southampton Catamaran Series published in the Transactions of RINA. In this paper the performance of this hull configuration is now being examined in a seaway and compared with the seakeeping performance of the DELFT-372 presented at FAST'11. The catamaran motions, namely pitch, heave and added resistance, in a seaway have been determined through regular wave tests in the Robinson Model Basin at Webb Institute at five different Froude Numbers ranging from Fn = 0.6 to 0.8. Complimentary to the experimental results, ship motion calculations have been made at the corresponding speeds using the potential flow program Aegir for direct comparison to the experimental results. These same calculations have been made for the DELFT-372 catamaran hull form for comparison with the experimental results presented at FAST'11. Finally the results of the experiments and the calculations on both hull forms will be compared to establish their comparative performance in a seaway.

NS Savannah was the first steam-powered ship to make an ocean voyage. It is a single-screw passenger cargo vessel with an overall length of 595 ft., a beam of 78 ft. and a design draft of 29 ft 6 inches. The machinery plant had a normal output of 20,000 shaft horsepower at 107 propeller revolutions per minute, which propelled the ship at 21 knots Her crew comprised 109 people, and she had cabin space for 60 passengers. Fission rate in the core was controlled by 21 cross-shaped control rods. These rods are made of boron stainless steel. Because the nuclear reactor is aborad the ship, the control rod mechanisms were designed to function normally at inclinations up to 30 degrees and to be held in place even in the event the ship capsized.

The location of trimaran side-hulls (amas) plays an important role in the wave-making resistance of the vessel. This research investigated interference effects for a Naval Surface Warfare Center, Carderock Division (NSWCCD) sealift concept design. The experiments were conducted at Webb Institute's Robinson Model Basin over a two year period. This data is thought to be one of the most comprehensive sets of test data on side-hull placement for a single model. The experimental results have been incorporated into four artificial neural networks (ANN). The end result is a series of matrix equations that continuously predicts residuary resistance, trim and sinkage, over a range of staggers and transverse spacings for the concept hull. While the ANN results are specific to the vessel in question, they shed light on the level of sensitivity of side-hull placement on trimaran calm water resistance. © 2011 American Society of Naval Engineers.

Propulsion of liquefied natural gas (LNG) ships is undergoing significant change. The traditional steam plant is losing favor because of its low cycle efficiency. Medium-speed diesel-electric and slow-speed diesel-mechanical drive ships are in service, and more are being built. Another attractive alternative is combined gas and steam turbine (COGAS) drive. This approach offers significant advantages over steam and diesel propulsion. This paper presents the case for the COGAS cycle. © 2011 Harbin Engineering University and Springer-Verlag Berlin Heidelberg.
