Naval Architecture

The present publication is the very good course in naval architecture covering the essential theoretical knowledge required to be possessed by the naval architects. The main objective of the author was to acquaint the trainees with the theoretical basics and provide the clear explanation on their interrelation and progressive application in the ship hull design. Note that it should not be looked at as a replacement to any standard reference volume but shall rather be treated as a leading title.

It will be the excellent reference source for the students of the naval architecture. In fact this is a good introduction, as it is clearly stated in the title of the book, and those willing to get a deep understanding and knowledge of the subject, should spend more time and efforts. The readers will go through the entire process of ship hull design, understand how the main hull characteristics shall be chosen so that the requirements advised by the clients, can be satisfied.

The book is recommended to the students and is a perfect supplement to any standard training program. The material is explained in a very simple and understandable way, including all calculations as well as the design matters.

The main objective of the present technical paper was the introduction of the essential principles of the small fishing vessel stability as well as provision of the clear guidance on what shall be done by the crew members of the subject vessels in order to keep the stability maintained adequate. It is mainly aimed at the people engaged in the fishing industry including the mariners, shipbuilders, owners of the fishing vessels and all other parties.

We would also recommend the publication to be used as guidance for the people caring about the safety of their ship. The book opens with a brief introduction followed by the definitions of the terminology used. After that, the main precautions relating to the small ship stability are provided, including securing of the heavy items and free surface effect, icing and catch stowage, quartering and following seas, means of closing etc.

The alterations done to the ship construction are addressed in the next chapter. The stability criteria applied to the small fishing vessels are dealt with in detailed within a separate section, followed by the stability documentation including the hydrostatic and cross curves, operating conditions and other aspects.

Over the past several decades there have been many significant changes in the maritime industry. Vessels of today are much bigger and their speeds are higher, their manning has been reduced; there are now so many types of ships including newly introduced ones, for example hovercrafts; ferries carry much more passengers and vehicles than in the past.

And even taking into account that people may now perform much quicker and much more accurate assessment of the ship stability and strength of the ships' hull together with the maneuvering and powering of the ships and their motions at sea by means of the very complex and specialized computer software, the basic concepts of the naval architecture remain unchanged and are valid as ever.

Some very rapid technical advances have been made in the field of the ship design, ship construction and ship operation, and many of them directly relate to the effectiveness. This is mainly owing to the higher efficiency and lower costs of the computers and proliferation of the available information.

This book of ship's theory consists of two separate volumes providing readers with the coverage of all important aspects, including trim and floatation, ship stability, potential hazards and protection of the ship, hull girder, structural design of the ship and associated analysis, launching of the ships and their docking, powering, seakeeping and maneuverability, major design features and so many others.

The present book is very important and useful because of the approach applied by the author to the problems relating to the loss of ship stability by means of the study of different operational aspects together with the dynamic ship behavior in severe condition of the sea and offering a complete picture of the selected modes of stability failure not currently covered by any criteria or applicable regulation.

The original motivation for the idea that has driven subject approach and the requirement to address the assessment of the ship stability is coming from numerous observations on losses of stability and capsizing of the ships. Though there are several regulations in force that all refer to the stability of the vessels, so many ships continue to loss their stability and capsize.

The subjects elucidated within this volume represent parts of the works relating to the critical importance of the assessment of ship stability and fit into the complex research system relating to the intact stability of the vessels, and particularly to the failure modes and how the proper assessment of the stability might prevent the possible losses. Five chapters of the book provide the general information and provide the historical background and analysis, cover the failure modes including ones in the severe conditions, and shed some light on the possible improvement in the field.

The present title was specifically released to assess the current situation in the field of the CFD, standing for the computational fluid dynamics, applied to the hydrodynamics of vessels; it is also intended to provide all specialists in this area with the required technical guidance to be used to the future developments. The main content of this volume is based on the materials presented during the stability workshop held in 2010 in Gothenburg.

The book is presenting the test cases as well as the data collected during the experiments and various computational methods. The publication also contains detailed analysis of the errors for local and global flow variables, including the standard deviations for the global variables and also propeller modeling for the self-propulsion. The authors of the materials contained in the book have also evaluated the effects of the grid size and also turbulence models and conducted the thorough analysis of the turbulence modeling capabilities to capture the physics of the local flow.

They have used the resistance submissions for evaluation of the errors and uncertainties using the systematic V&V, i.e. verification and validation, study together with the statistical investigations. Moreover, they have also analyzed all related computational and experimental studies...

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.

Here is the second edition of this book which continues to serve as one of the most complete and comprehensive guides to proper understanding of the ship hydrostatics together with the associated design and performance matters, taking readers from the basic principles to the serious and detailed analysis.

   The practical application of the hydrostatics has been illustrated using the real-life examples and calculations conducted in Excel and MATLAB programs. Apart from the traditional content, this release of the book includes the definitions and also indexes presented in four languages in order to make the material accessible to the international readers.

As always, the book is equipping the naval architects with the required theoretical knowledge and context to get the understanding oh the stability through all stages from design to the construction and use, it is covering the pre-requisite basic theory including the dimensions and geometry of the ship's hull, calculation of moments and numerical integration, and it is outlining a clear approach to the modeling of stability and its analysis my means of the contemporary methods of computation, covering the international recognized standards and applicable regulations governing the stability. An excellent publication which have deservedly gained the world popularity and recognition among both students and specialists.

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...
