This book is intended as an introduction to classical water wave theory for the college senior or first year graduate student. The material is self-contained; almost all mathematical and engineering concepts are presented or derived in the text, thus making the book accessible to practicing engineers as well.The book commences with a review of fluid mechanics and basic vector concepts. The formulation and solution of the governing boundary value problem for small amplitude waves are developed and the kinematic and pressure fields for short and long waves are explored. The transformation of waves due to variations in depth and their interactions with structures are derived. Wavemaker theories and the statistics of ocean waves are reviewed. The application of the water particle motions and pressure fields are applied to the calculation of wave forces on small and large objects. Extension of the linear theory results to several nonlinear wave properties is presented. Each chapter concludes with a set of homework problems exercising and sometimes extending the material presented in the chapter. An appendix provides a description of nine experiments which can be performed, with little additional equipment, in most wave tank facilities.

The goals of wind wave research are relatively well defined: to be able to predict the wind wave field and its effect on the environment. That environment could be natural (beaches, the atmosphere etc.) or imposed by human endeavour (ports, harbours, coastal settlements etc.). Although the goals are similar, the specific requirements of these various fields differ considerably.This book attempts to summarise the current state of this knowledge and to place this understanding into a common frame work. It attempts to take a balanced approach between the pragmatic engineering view of requiring a short term result and the scientific quest for detailed understanding. Thus, it attempts to provide a rigorous description of the physical processes involved as well as practical predictive tools.

Load and Global Response of Ships gives an introductory background to naval architecture statistics and strength of materials. Each subject is treated in detail; starting from the first principle. The aim of this title was to derive and present the necessary theoretical framework for predicting the extreme loads and the corresponding hull girder stresses that a ship may be subjected to during its operational lifetime.Although some account is given to reliability analysis, the present treatment has to be supplemented with methods for detailed stress evaluation and for structural strength assessment before a complete structural reliability analysis can be carried out.The classification societies have issued rules and regulations for a proper structural analysis of a ship and selection of the scantlings. Previously, those rules rather explicitly gave formulae for the thickness of the hull plantings, the size of the stiffeners etc. Such empirical rules must necessarily be rather conservative in order to apply to a large variety of ships. With the advent of powerful computers, the rules have changed. Today, the naval architect can perform the structural analysis using mainly rational methods based on first principles. The classification society may then specify proper safety factors against local global failure modes, taking into account the consequences of failure and the analysis procedure used. A cruder method of analysis then necessitates a larger safety factor. Therefore the effort made by the experienced naval architect to perform a detailed structural analysis will be returned not just by a rational structural arrangement but also often in lower weight of the ship and thus a higher payload throughout the operational lifetime of the ship.This analysis has attempted to make explicit one way in which designers limit the design space by creating rules to which they expect users to adhere. It is also an attempt to encourage designers to reconsider the 'rules of use' that they have used in their designs, so as to reconceptualise potential usage. This can help design behaviour where rule use is not blindly followed.By making these rules visible, it is possible to expose the limitations of current technology, and development design solutions that do not restrict use to the 'normal' case of action. Rules are useful to designers because they are simplifications of activity. Rules encode the normal case, and these are simplistic representations of work that are, in many cases, accurate enough for the purpose of design. However, encoding behaviour in rules has dangers in that they do not encompass the whole range of behaviours that can be performed. Using examples, this title shows that being able to break rules means that people are able to engage in a richer more flexible set of actions (and therefore more appropriate to contingency) than when they are constrained to a limited range.

Hurricanes are one of the most adverse aspects of the ocean environment, with the potential to cause a disastrous event for marine systems in the ocean. Hurricane Generated Seas is an invaluable reference for all involved in the field of naval, ocean and coastal engineering. The work clarifies hurricane generated sea conditions necessary for the design and operation of marine systems in a seaway, and provides information for the protection of near shore / onshore structures and the environment at the time of hurricane landing. - Reveals Information vital for avoidance of disastrous events experienced by ships and offshore structures - Includes detailed analysis of hurricane sea wave data obtained by buoys
