Download or read book A Rational Strip Theory of Ship Motions written by T. Francis Ogilvie and published by . This book was released on 1969 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The exact ideal-fluid boundary-value problem is formulated for a ship forced to heave and pitch sinusoidally in otherwise calm water. This problem is then simplified by applying three restrictions: (1) the body must be slender; (2) the motions must be small in amplitude compared with ship beam or draft; (3) the frequency of oscillation must be high. The hydrodynamic problem is then recast as a singular perturbation problem which is solved by the method of matched asymptotic expansions. Formulas are derived for the hydrodynamic heave force and pitch moment, from which added-mass and damping coefficients can be easily obtained. The latter are similar but not identical to those used in several other versions of 'strip theory;' in particular, the forward-speed effects have the symmetry required by the theorem of Timman and Newman, a result which has not been realized in previous versions of strip theory. In order to calculate the coefficients by the formulas derived, it is necessary to solve numerically a set of boundary-value problems in two dimensions, namely, the problem of a cylinder oscillating vertically in the free surface. At least two practical procedures are available for this purpose. (Author).

Download or read book The Impulse Response Function and Ship Motions written by W. E. Cummins and published by . This book was released on 1962 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: After a review of the deficiencies of the usual equations of motion for an oscillating ship, two new representations are given. One makes use of the impulse response function and depends only upon the system being linear. The response is given as a convolution integral over th past history of the exciting force with the impulse response funcion appearing as the kernel. The second representation is based upon a hydrodynamic study, and new forms for the equations of motion are exhibited. The equations resemble the usual equations, with the addition of convolution integrals over the past history of the velocity. However, the coefficients in these new equations are independent of frequency, as are the kernel functions in the convolution integrals. Both representations are quite general and apply to transient motions as well as periodic. The relations between the two representations are given. The treatment considers six degrees of freedom, with linear coupling between the various modes. (Author).

Download or read book The Unified Theory of Ship Motions written by J. Nicholas Newman and published by . This book was released on 1980 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: A linear theory is presented for the heave and pitch motions of a slender ship, moving with forward velocity in calm water. The velocity potential includes a particular solution similar to that of the high-frequency strip theory, plus a homogeneous component which accounts for interactions along the length in an analogous manner to the low-frequency 'ordinary' slender body theory. The resulting 'unified' theory is valid more generally for all frequencies of practical importance. Computations are presented for the added-mass and damping coefficients of a floating spheroid, a Series 60 hull, and a frigate. Comparisons with experimental data and with zero-speed exact theories confirm the utility of the unified theory. This theory can be used to analyse the performance of elongated wave-energy absorbers. This application is illustrated for a hinged 'Cockerell' raft.

Download or read book High Speed Catamarans and Multihulls written by Liang Yun and published by Springer. This book was released on 2018-10-29 with total page 783 pages. 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 Risk Based Ship Design written by Apostolos Papanikolaou and published by Springer Science & Business Media. This book was released on 2009-04-09 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: Risk-based ship design is a new scientific and engineering field of growing interest to researchers, engineers and professionals from various disciplines related to ship design, construction, operation and regulation. The main motivation to use risk-based approaches is twofold: implement a novel ship design which is considered safe but - for some formal, regulatory reason - cannot be approved today and/or rationally optimize an existing design with respect to safety, without compromising on efficiency and performance. It is a clear direction that all future technological and regulatory (International Maritime Organisation) developments regarding ship design and operation will go through risk-based procedures, which are known and well established in other industries (e.g. nuclear, aviation). The present book derives from the knowledge gained in the course of the project SAFEDOR (Design, Operation and Regulation for Safety), an Integrated Project under the 6th framework programme of the European Commission (IP 516278). The book aims to provide an understanding of the fundamentals and details of the integration of risk-based approaches into the ship design process. The book facilitates the transfer of knowledge from recent research work to the wider maritime community and advances scientific approaches dealing with risk-based design and ship safety.
