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.

One of the main objectives of the present document is to develop a fast and stable plus reasonably accurate method of numerical simulation in order to revisit and predict the flooding scenarios. The author, Henrin Dankowski, has performed a good professional comparison with the results obtained in the course of the standard benchmark tests and repeated investigation of three accidents, namely the Estonia, the Heraklion and the European Gateway, for validation purpose.

The aim of the method presented in this volume was to fill the gap that exists there between relatively simple evaluations of ship stability and more complex and time consuming methods of simulation of the seakeeping. Subject method has been implemented in the software environment E4 specifically developed for ship design. Subject environment is providing users with the direct access to the complete vessel data model and to the computational algorithms that have already been implemented.

Calculations of the damage stability of a vessel at early stages of the design are considered essential indication of the vessel's safety level to withstanding the water ingress. Several accidents that have occurred in the past are demonstrating how important it is to consider the intermediate stages of flooding process and not only looking at the resulting final stage.

A truly timeless textbook on naval architecture providing all interested people, and not necessarily professionals. with a required introduction to this interesting discipline - in fact, the way in which the material has been presented in this book makes it ideal even to the newcomers having limited knowledge of this subject.

Eric Tupper, the author of this brilliant and world popular title, made a remarkable attempt to make a book equally useful to all categories of readers, giving them a very clear yet quite concise introduction. We all understand that the basic characteristics of the design and the way they impact the behavior of the ship at sea are of critical importance to the people.

Of course, the practicing naval engineers must have a very deep and thorough understanding of all technical principles involves; however, the pro's supporting naval architects in design and production of the ships will also need some good grasp of the fundamentals.

Marine engineers should recognize the exact degree to which their everyday working activities are influenced and bounded by the basic principles of naval architecture. The present publication covers the basic of the naval architecture and will therefore present a great practical interest to students and specialists in the fields of ship construction and marine engineering.

The main declared purpose of the author of the present thesis was to develop a procedure for the analysis of the ship collisions that would address all ship types and all possible damage scenarios. Among the main aspects covered within this work are the deterministic analysis and numerical Monte Carlo-based simulation of collisions to estimate the distributions for the damage expected to occur to the struck vessel and released energy, damage statistics analysis, and new proposal for the regulations governing the damage stability applying the probabilistic approach.

Three new programs have been developed and introduced for the deterministic analysis, addressing the damage to the struck vessel, striking vessel and to both of them. The author has conducted a thorough analysis of the information contained in the database of the damage from collisions occurred in the past with respect to the type of collision and relation between vessels plus the parameters of damage and the main particulars.

Chapters of the thesis cover the risk analysis, external dynamics and internal mechanics of ship collisions, deterministic and probabilistic analysis of collisions, damage statistics, comparison of the results obtained in the course of the observations and simulations, stability regulations, input for the collision programs, damage relations and other relevant information.

One of the most popular and classical books on naval architecture, "Principles" is arranged in three volumes. You will find the first of the volumes here (and here are Part 2 and Part 3). The initial edition of this book was released in 1939 and, according to the editors, adequately covered the whole field of naval architecture in a single text. The revision hereby presented to your attention has been conducted in order to duly reflect all recent technical developments and make all necessary improvements to the original content.

This book is actually aimed to bring the subject of naval architecture up-to-date by means of re-writing the areas where the most important advances took place. One of the main objectives of this set of books is to provide all readers having serious interest in naval architecture with a remarkably timely survey of the fundamental principles; the books are expected to be of great use for active professional as well as for the students.

The content of the first volume has been arranged in four big parts covering the geometry of the vessel including the lines drawing, form coefficients, relationship between weight and displacement, hydrostatic curves, capacity etc., elementary principles of intact stability, its evaluation, displacement, trim, draft and other characteristics, subdivision of the hull and damage stability, and, finally, the strength of the ship's hull.

The second part of the set (here are Part 1 and Part 3). This books addresses the ship resistance, ship propulsion and ship vibration. The ship resistance-related chapter provides all necessary theoretical information of the resistance types, surface vessels and submerged objects, dimensional analysis, frictional and wave-making resistance, plus other resistance components, use of the models for determination of the hull resistance, presentation of the model resistance data, HSC and advanced marine vehicles, and relation of the ship hull form to its resistance.

The propulsion-related chapter deals with the powering of vessels, propeller action theory, similitude law, self-propulsion tests, geometry of the screw propellers, interaction between ship's hull and propeller, cavitation, ducted propellers, various design matters, standardization trials and other devices for ship propulsion. Finally, the chapter covering the ship vibration provides the general information on the subject, covering the fundamental theoretical concepts, analysis and design issues including diesel engine and propeller excitation, applicable criteria and associated measurements, and other topics. The separate part of the volume has been dedicated to the nomenclature used throughout the book and in naval architecture, in general.

And this is the third part of volume of the set of Naval Architecture books (Part 1 and Part 2 here), and the present volume is dedicated to the motion of ships in waves and their controllability, i.e. the last two chapters of the course. Taking into account the importance of all recent theoretical and also experimental developments in the subject fields, the authors considered it necessary to fully rewrite the content of both those chapters and to add a great portion of the new material.

The chapter on motion in waves covers such the important aspects as the characteristics ocean waves, their origin and propagation, responses of the vessel to the ocean waves, ships in the seaways, derived responses and ship motion control, assessment of the ship seaway performance, various aspects of design, and relevant nomenclature. The chapter covering the controllability addresses the control loop together with the basic equations of ship motion. stability and associated linear equations, stability and control, turning ability, controls-fixed stability and coursekeeping, hydraulic models, free-running tests, non-linear motion equations, acceleration/stopping/backing, hydrodynamic coefficients, auto-control systems, waterway interactions, performance requirements, design applications, special symbols, control devices and many other critically important topics.

During the past decade considerable changes have been there in the approach of the scientists to the problem of ship stability and particularly to the impact it has on the merchant shipping. The most obvious of those changes were the introduction of the metric system as well as significant increase in the number and content of the examination requirement as well as establishment of the recommendations related to the standard method of presentation and utilizing of the stability information.

The present seventh release of the book has been specifically designed and released with the intention to meet all of those requirements. Most of the fundamental information contained there in the opening chapters of the book has been retained for the benefit of the readers not familiar with this subject. The remaining part of the text has been expanded and re-arranged in order to lead into the newly introduced materials; note that there is also one new chapter dealing with the stability information to demonstrate the standard presentation method.

The theory has been covered according to the standard that is commonly required for a Master's Certificate including all information required by the students. This information has been linked up with the real-life practice. Particular attention was paid by the authors to the matters which might be misunderstood or not appreciated in full...
