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.
This training document was prepared by the Homeland Security Department of USCG, which maybe is the most authoritative regulatory and control organization in the maritime world. The booklet will provide required guidance in the stability of fishing vessels. The basic stability concepts have been introduced in the pages of this volume which will be practically interesting for the crew members and owners of the fishing ships, as well as to any other parties involved in commercial fishing.
The book will tell the readers about stability, providing them with the answers to such question as how does stability of the vessel work and how is the stability determined. They will understand the difference between initial stability and overall stability and get a lot of other useful information covering a widest range of different subjects related to the stability of the fishing vessels. The authors have listed the most important lessons at the beginning of the sections in order to assist readers.
The readers will also know what they can do to let their vessel maintain adequate stability and understand how the operation of the vessel affects stability. The book was written having crew members and not professional naval architects in mind, so the information is presented in a simple and clear language to make it understandable for everyone on board and ashore.
This work by Edward Attwood is an expansion of his Textbook of Theoretical Naval Architecture which was published more than a century ago. The content of this book has been prepared with the intention of the author to provide all readers, including students of naval architecture and professional draughtsmen with a good and useful textbook explaining the calculations they are continually involved in every day.
The book is expected to form a textbook for the different exams held in naval architecture. Since this subject is constantly growing, it is really impossible to confine all relevant information in a single volume; however, the author has tried to demonstrate how exactly the ship calculations could be carried out in the intelligent manner giving students a perfect fundamental knowledge on which the further progress in the field can be achieved easier.
One of the special features of this volume is a huge number of the examples provided in the text as well as at the end-chapters, and this feature has been found to be greatly appreciated by the readers, and students, in particular. The author of this classic and really brilliant textbook hopes that his work would be found practical and useful to that class of readers which is willing to obtain a good working knowledge of the basic principles of naval architecture.
Geometry is the discipline directly dealing with the properties and measurements plus the relationships of the points and their sets. Vessels and other marine structures are really large and usually quite complex objects therefore the final success of their planning and further production mostly depends on proper geometric descriptions of the components they usually consist of, as well as on their positional relationships.
Traditionally, a 3D models of representation are utilized, and particularly at different scales and lesser levels of details in comparison to the actual objects. The process of producing real products commonly consumes large quantities of the material, human and time resources which will of course be considered wasted should the final result of this production process be functioning not in a way it was originally supposed to function.
This volume covers the most important aspects of the ship geometry, such as the geometric modeling as applied to the marine design, coordinate systems, geometry of curves/surfaces, subdivision surfaces and geometry of solid objects, polygon meshes, definition of the hull surface, weight/displacement, form coefficients of the ship hulls, hydrostatic analysis, capacity and arrangement issues including tonnage, subdivision of the compartments, tank and container capacity, decks and bulkheads as well as superstructures and hull appendages...
The author of this publication has successfully adopted a practical approach and has presented all recent researches and also different practical applications in the real-life design and operation of the submarines. The list of topics covered within this volume is including the hydrostatics and maneuvering of the submarines, and their resistance and propulsion problems.
The author has conducted a brief review of the fundamental technical concepts in ship hydrodynamics and then proceeded to the demonstration of how exactly subject concepts could be applied to the submarines, covering the use of the physical model experiments. He has also clearly explained all issues commonly associated with the maneuvering of the submarine in the vertical/horizontal planes allowing readers to discover the suggested stability criteria, together with the effectiveness of the rudder and also hydroplane.
The publication also is including a separate section covering the design of the hull appendages including all technical info relating to the sail design and arrangement of the bow planes plus alternative configurations of the stern part of the submarine. Among the other topics that have been addressed in this volume we would mention the hydro-acoustic performance, different resistance components and hull shape effect. The content reflects a great experience of the author in this field of submarine design.
Here is a re-print of the classic book on the theoretical foundations of naval architecture. This book will be of great interest for the naval architects and other workers of the shipbuilding facilities and drawing offices because it will offer them an excellent text clearly explaining all associated calculations.
The author of this volume is also expecting that his work may serve as a standard textbook covering the whole theoretical portion of the exam in naval architecture. Unfortunately, it was not possible to include literally all subjects, for example such subjects as the advanced stability work, vibration, rolling of the vessels and some others. However, the author has really made his best to cover as many of the important topics of naval architecture as possible, and to provide readers with a huge amount of interesting and understandable theoretical information on the naval architecture basics.
One of the special features of this title is the number of practical examples presented in the text of the book as well as at the end of the chapters. These subject are aimed to help students test their grasps of processes and processes covered within the paper. Most of the examples have been taken from the real calculations of different drawing offices and this makes them practically useful.
All intended readers will definitely find that the present volume is not a sort of books with glossy images of fabulous and glamorous yachts. It is much more scientific and sober than those titles. The main objective of the compilers of the present training course was to provide all interested readers, and yachtsmen in particular with the racing ambitions with a good technical background of the mechanics of sailing, including both hydro- and aeromechanics.
The original intention of the author of the volume was to present all materials in a way that could be justifiable from his own background, while all efforts have been made to keep the content easily accessible for the people without actual academic schooling. The book starts with a list of used notations and symbols followed by the introductory chapter.
Then the main content of the publication comes arranged in several sections covering the geometry of the sailing yacht and mass properties, basic mechanics and fundamental elements of the fluid mechanics, forces acting above the surface of the water, i.e. aerodynamics, and forces acting under the water, i.e. hydrodynamics, sailing hydrodynamics and aerodynamics, retrospection. Several appendices are there at the end of the volume providing some valuable additional information on mathematical notions, Kelvin ship waves, and other important aspects.
A new, revised edition of the book; it's content is based on the revised content of the original edition subjected to serious revision to correct the existing errors and also to update the text part. It comes quite clear from the thorough review of the established international/national practices of stability regulation that the development of the associated standards has been initially commenced by the leading experts working in the field of naval architecture.
The ultimate objection of setting up the technical standards that pertain to the stability of the vessels was to ensure the safe operation of the vessels and eliminate the possibility of their capsizing. The materials presented in this volume are arranged in two big parts addressing the probabilistic approach to the ship stability and also risk assessment and dynamics of ship's capsizing.
While the first part of the volume is mainly dedicated to the philosophy of the probabilistic evaluation of ship stability/safety plus of the loading and environmental conditions, its second part covers the equations for the non-linear motions of the ship, capsizing of the vessels in regular beam, quartering and following seas, different factors commonly affecting capsizing, motions in irregular seas, capsizing probability and other aspects. The appendix at the end of this volume has been fully dedicated to the Nechaev method.
