Available in PDF, EPUB and Kindle. Book excerpt: To predict motions of SWATH ships in following seas, especially when the encounter frequency is small, unified slender-body theory has been applied. The longitudinal interaction term is computed and added to the results of the strip theory as a correction term. The added mass coefficients are computed to be much larger than those from strip theory, while damping coefficients are slightly less than two-dimensional results. There is improvement for heave motion for a limited range of frequencies, but the pitch motion is generally poor. To improve these results, further, the two-dimensional potential should be solved by the multipole expansion method rather than by the Frank close-fit method. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: High speed catamaran and multihull high speed marine vessel have become very popular in the last two decades. The catamaran has become the vessel of choice for the majority of high speed ferry operators worldwide. There have been significant advances in structural materials, and structural design has been combined with higher power density and fuel efficient engines to deliver ferries of increasing size. The multihull has proven itself to be a suitable configuration for active power projection across oceans as well as for coastal patrol and protection, operating at high speedd for insertion or retrieval with a low energy capability. At present there is no easily accessible material covering the combination of hydrodynamics, aerodynamics, and design issues including structures, powering and propulsion for these vehicles. Coverage in High Speed Catamarans and Multihulls includes an introduction to the history, evolution, and development of catamarans, followed by a theoretical calculation of wave resistance in shallow and deep water, as well as the drag components of the multihull. A discussion of vessel concept design describing design characteristics, empirical regression for determination of principal dimensions in preliminary design, general arrangement, and methods is also included. The book concludes with a discussion of experimental future vehicles currently in development including the small waterplane twin hull vessels, wave piercing catamarans, planing catamarans, tunnel planing catamarans and other multihull vessels.

Download or read book Hydrodynamics of the 190 ton Stable Semisubmerged Platform SSP written by T. G. Lang and published by . This book was released on 1974 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The form, hydrodynamic design, and predicted performance of the 190-ton Stable Semisubmerged Platform (SSP) are described and analyzed. Design criteria are presented for the twin submerged hulls, four surface-piercing struts, bow section of the above-water cross structure, aft stabilizing fin and flaps, forward-mounted canard control surfaces, rudders, and the controllable and reversible propellers. Hydrodynamic loads and motion in waves are analyzed. The overall design is evaluated in light of design experience, model test results, and preliminary operating experience with the 190-ton SSP. The 190-ton SSP is shown to have significantly reduced motion in waves, increased rough-water speed and more deck space and internal volume than conventional monohulls. (Author).

Download or read book Experimental Measurements of the Deformation of Regular Head and Following Seas by a Ship Model written by Paul G. Spens and published by . This book was released on 1963 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes measurements of the changes in amplitude of regular head and following waves as they passed along the length of a ship model for model speeds zero, Froude number 0.1, and Froude number 0.3. In head seas the height of the incident wave diminished by some 20% to 40% as it passed along the length of the fully restrained model from bow to stern. In following seas the wave diminished by some 50%, from stern to bow when the ship speed was less than the wave group velocity, and from bow to stern when the ship speed was greater than the wave group velocity. These experimental results are generally in fair agreement with Grim's theoretical predictions. However, at forward speeds in head seas, there are local variations of wave height near the bow which are not predicted by the theory. (Author).
