Naval Architecture

The hydrostatic approach applied to the problem of ship stability intends to find a due balance of the idealized weight of the ship and buoyancy forces acting on the hull. The present textbook may be treated as a complete guide book to be used by the students and even professionals willing to get better understanding of the ship hydrostatics in the design and performance of the vessels.

The author of the volume is bringing the readers from the first fundamental principles through both basic and applied theory of hydrostatics and ship stability, and he is also introducing the modern and newly presented mathematical techniques used for hydrostatic modeling and analysis. Numerous real-life examples have been included in the book to show the practical application of the hydrostatics and explain the theory and calculations; they will also help to demonstrate the effects of the shifting weights and displacements of the central gravity on the overall stability of the vessel.

The content of the book addresses all recent developments in naval architecture, for example the Matthieu effect relating to the parametric resonance, influence of the ship lines, effects of nonlinear ship motions on stability, and the international regulations governing the stability of the small vessels with the extensive use contemporary computer techniques...

The present title is intended to provide the required introductory technical background to the naval architecture statistics. Each of the subjects discussed within this volume has been treated in detail, and this approach has been applied starting from the very first principle. The main objective of J. Jensen, the author of this volume, was to derive and present readers all required theoretical information for the prediction of the extreme loads and evaluation of the corresponding stresses in the hull girder of the ship.

Though some part of the book is dedicated to the reliability analysis, this treatment shall be supplemented with the methods for the detailed evaluation of stress and also for the assessment of the structural strength of the ship's hull prior to the commencement of the reliability analysis. The class societies have issued their regulations covering the structural analysis of a vessel and proper selection of its scantlings. In the past, subject regulations gave formulas for the calculation of the hull thickness and size of the stiffening members.

Such empirical regulations must be conservative so that they can be applied to the majority of the vessels. However the regulation have been changed with the advent of the powerful computers. Nowadays, naval architects can perform the structural analysis of the hull using the rational methods that are based on the first principles...

An excellent course to be checked by all students of naval architecture. The book was prepared and published by the Maritime University Constanta. The main content of this publication has been divided into numerous sections. The first section of the book addresses the basic principles and introduces the students to the laws that are commonly governing the flotation and this information will help them understand why the vessels float at all; the information provided in this opening section will help in forming the very basic level of knowledge required to complete subject training program. It is followed by the sections addressing the form coefficients of the ship's hull, TPC, Load Lines, basic introduction to the transverse stability, conditions of stability, effect of the free surface on stability, centre of gravity, list and trim, centre of buoyancy, GZ curves and suspended weights.

The remaining sections of the book are dealing with the stability criteria, wall-sided formula, inclining test, ice acceleration, wind heeling, curves of statical stability etc. Some of the practical problems of ship loading have also been covered, together with the international regulations, e.g. IMO Grain Code. At the very end of the book there is an illustrative example of the Stability Information & Tank Sounding Book that can be used for ready and easy reference.

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 book starts with the five chapters providing readers with the general introduction to the hydrodynamics of the ship's hull. It is assumes that the readers have a solid knowledge of the general fluid dynamics. Though there are numerous books available on the market, it should be underlines that naval architects must concentrate on selected aspects of their field and try to cover the materials exactly suited to their practical needs, and this is a strategy supported by the author of this title.

The first of the chapters gives an introduction to the CFD while the other four chapters are covering the areas of propeller flows, hull resistance and ship propulsion, seakeeping and maneuvering of the ship. This is the recommended sequence of teaching. The aim of these chapters is to find a balance for the practical naval engineers between the facts and minimum of formulas. However,  some formulas are still there included to help people engaged in computations or programming tasks.

People having only practical interest may easily ship these passages. The final two chapters of the book are involving a bit more extensive formula work and are therefore more specialized; they have been reserved mainly for the post-graduates and will assist them in gaining the proper understanding and development of the boundary element codes...

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...

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.
