Describes results of measurements and predictions of ship motions, hull pressure loads, and vertical bending moment loads from sea trials undertaken during various operational conditions in moderate seas. Motion and hull pressure spectra derived from the measurements are compared to predictions computed by combining regular wave transfer functions computed with PRECAL, a three-dimensional linear ship motion and load prediction code, with directional wave spectra collected with a directional wave buoy during a trial. Vertical bending moment spectra calculated in a similar manner are compared to bending moment spectra derived from measured strain spectra and full-ship finite element analysis.

Describes results of sea trials on the ship CFAV QUEST undertaken to evaluate advanced methods of sea load and structural response predictions. Motion and hull pressure spectra derived from measurements recorded on CFAV QUEST during various operational conditions in moderate seas are compared against predictions determined by combining regular wave transfer functions computed using PRECAL (a three dimensional linear ship motion and load prediction code) with directional wave spectra collected with a wave buoy during the trial. Predictions of vertical bending moment spectra calculated in a similar manner are compared to bending moment spectra derived from measured strain spectra and full ship finite element analysis. The results indicate the degree of potential of using PRECAL in combination with structural finite element methods to predict structural response spectra for use in spectral fatigue analysis of ship hull structures.

Practical Ship Hydrodynamics provides a comprehensive overview of hydrodynamic experimental and numerical methods for ship resistance and propulsion, maneuvering, seakeeping and vibration. Beginning with an overview of problems and approaches, including the basics of modeling and full scale testing, expert author Volker Bertram introduces the marine applications of computational fluid dynamics and boundary element methods. Expanded and updated, this new edition includes: Otherwise disparate information on the factors affecting ship hydrodynamics, combined to provide one practical, go-to resource. Full coverage of new developments in computational methods and model testing techniques relating to marine design and development. New chapters on hydrodynamic aspects of ship vibrations and hydrodynamic options for fuel efficiency, and increased coverage of simple design estimates of hydrodynamic quantities such as resistance and wake fraction. With a strong focus on essential background for real-life modeling, this book is an ideal reference for practicing naval architects and graduate students.

Sonar performance modelling (SPM) is concerned with the prediction of quantitative measures of sonar performance, such as probability of detection. It is a multi-disciplinary subject, requiring knowledge and expertise in the disparate fields of underwater acoustics, acoustical oceanography, sonar signal processing and statistical detection theory. No books have been published on this subject, however, since the 3rd edition of Urick’s classic work 25 years ago and so Dr Ainslie’s book will fill a much-needed gap in the market. Currently, up-to-date information can only be found, in different forms and often with conflicting information, in various journals, conference and textbook publications. Dr Michael Ainslie is eminently qualified to write this unique book. He has worked on sonar performance modeling problems since 1983. He has written many peer reviewed research articles and conference papers related to sonar performance modeling, making contributions in the fields of sound propagation and detection theory.

Deals with the prediction of speed and power in ships -- an important part of ship design. Describes the techniques used in ship model experiments as well as different types of experimental facilities. Considers different methods of estimating or determining speed and power. Questions regarding wake, thrust deduction, cavitation, and propeller design are covered. Correlates the interaction between ship, machinery, and propeller. Includes a thorough exposition of shipyards' and shipowners' needs for model testing. Extensive drawings and diagrams highlight the text.
