This book was written by A. Hermans with the intention to provide readers with a general technical introduction to the various aspects of the water waves playing the important roles in hydrodynamics of ships as well as offshore engineering. Firstly, it derives the equations and linearized boundary conditions that describe the non-viscous free waves with the particular attention being paid to the combination of non-steady and steady flow fields.

After that, the author derives some of the simple types of free wave solutions, for example cylindrical and plane waves. The source singularity function has also been derived for several steady and unsteady situations; subject functions are playing a role in the numerical codes that are used for the description of the ship's motion. The content of the publication is divided into eight major chapters addressing the water waves theory, second-order theory, non-linear and irregular waves, linear wave phenomena and asymptotic formulation, and other important technical aspects of the ship hydrodynamics.

The appendices at the last part of the book are providing such important additional information as the methods of characteristics and of stationary phase, two-dimensional Green's function, singular integral equations and simplification of the relevant algebraic equations. A very useful and practical volume for ship designers.

Suppose for a minute, what if you have been assigned the task to perform the mapping of the general circulation in some completely unfamiliar ocean. The ocean is sub-divided into several basins as well as marginal seas which, in turn, are connected with each others by means of the sea straits. Taking into consideration the possible budget limits for this task, you would most probably choose the sea straits as the starting points for the observation.

To start with, the ocean currents that flow between the basins, over the wide paths that can also be time-varying, are commonly confined to the relatively stable and narrow routes within those straits. Such confinement could result in the profound dynamical consequences, one of them being the choking/hydraulic control; subject process is quite similar to a process by which a dams are regulating the flows from the reservoirs.

Geometry of the funneling may lead to the significantly increased velocities and enhanced tidal modulation, which would in turn lead to the local instabilities, internal bores, plus jumps and mixing, and other events. Shortly, the straits shall be treated as the choke points being dynamically and observationally strategic and containing a broad range of physical processes, all of them being addressed within this book.

Twelve years back the Pacific Area USCG Commander proclaimed the intention of the United Stated to push back their sea borders by about two thousand miles. This step was actually expected by him to eliminate or at least significantly reduce the terror threat faced by America. And his statement actually reflected the new attitude that concerned the policing of the world oceans not only by America but also by some other countries.

The principles of navigation freedom of the traditional Law of the Sea and exclusive jurisdiction of the Flag States is considered a serious obstacle for fighting against terror and it also affects some other security concerns. And this, in turn, has resulted in the interferences on the high seas becoming common. The shipping industry witnessed the similar scenarios when the United Stated made attempts to fight international crimes, such as the piracy and pirate broadcasting, slave trading etc.

The present volume is providing the discussion on the most important issues involved, for example the international organizations and their responsibilities, lawful conduct and associated liability, and others considered important in today's world.

The publication of this book is timely - at the time of writing we are in the midst of very troubled times for the dry-bulk shipping markets. Falling demand for dry commodities, an oversupply of ships and a freeze in credit have seen daily hire rates for bulk carriers drop from all-time highs to near all-time lows within the space of a few months.

From freight rates to bunker prices, credit risk to asset values, the financial risks faced by shipping market participants are significant. The book provides readers with a proper understanding of the measurement process and on how to manage the volatility of the freight rate; the information in the book will also let the reader explore the options that are available to the professionals of the shipping industry.



The authors have made a brilliant compilation of the thorough investigation of the markets conducted y the recognized experts. That is why this volume is a must-have for both practitioners and researchers. Their efforts resulted in a truly unique publication combining both theoretical and practical aspects or the risk management, the readers who have gone through the material included in the book will get some essential knowledge of risk assessment and be enabled to understand all major freight derivatives tools.

The present book was specifically prepared for students, practitioners and researchers in the fields of control engineering and marine technology. Taking into account that the audience would be fairly mixed, so much effort has been made by the author to set the proper level of the topic presentation.

Nevertheless, the readers of this book are required to have at least some basic knowledge in linear systems/state space models, say within the limits of one provided at the standard undergraduate control courses. The publication contains four major sections; the first three of them are dealing with the key components of a successful vessel motion control system, namely appropriate math models, proper understanding of the performance assessment, and knowledge of the basic limitations that may possibly affect the desired performance in a negative way. The last part of the book addresses the design of control systems.

Among the topics that have been included in the book there are ship dynamics, wave simulation and modeling, vessel motion performance, wave filtering, design of the control system for auto-pilots and for integrated rudder-fin stabilizer, rol stabilization devices, various models of actuators etc. The book will be useful to practicing marine engineers as well as the academic persons involved in the related research activities.

This volume is elaborating on combination of the basic theoretical approaches and common practices of the preliminary design of the ship. The intention of the author was to support the introductory training courses of ship design as a textbook. Taking this into account, we may consider this book as so useful one to students of naval architecture as well as of all related disciplines.

We are quite sure that the book would actually serve as an excellent reference source not only for the students but even for the practicing naval architects, ship officers, marine engineers and anyone interested in ship design theory plus practical methodologies applied to the estimation of the ship's basic properties and main dimensions together with the other elements of design.

There are five appendices complementing the main content of the book providing some additional information on the different ships types and their characteristics, historical background, regulatory documentation, description of the relational method, etc. Definitely recommended reading for both professional and future ship designers who will benefit from the thoroughly prepared information provided in the volume.
