SHIP STABILITY BY DOKMAR

Ship stability is deservedly considered one of the most difficult concepts to define. The whole technical idea of a stable character is grasped even though it is quite hard to be put in words. Same would apply to the notion of a stable vessel because stability is a very complex entity. It still plays a critically important role in ship navigation. Should the ship be unstable, immediate danger arises to the vessel and people on board as well at to the surrounding environment.

That is the reason why the regulations have been established to govern the stability of the ships. One of the main strength of this volume is that it makes the ship stability visible to the readers and also makes it accessible and easily understandable even for the newcomers because of the approach applied by its author who has supplemented the theoretical part of the publication with numerous informative figures and illustrations as well as detailed drawings. The book is expected to be highly suitable for the professional training in the classroom or for the self-studying.

All required and important topics have been addressed in this volume together with the abbreviations and terminology used in the naval architecture and ship stability, in particular. Note that this book is an excellent supplement to another publication prepared by the same author under title Ship Knowledge so we would recommend you to have a close look into both books.

SHIP RESISTANCE AND PROPULSION

The volume has been fully dedicated to the provision of a modern and comprehensive scientific approach to the evaluation of the resistance and propulsion of ships. The masses of the propulsion engines can be established and fuel consumption and approximate operating costs can be estimated through the study of the propulsive power.

The present publication prepared by the world leading experts includes the recent developments from the applied researches including the researches conducted in CFD and also experimental techniques, providing all required guidance for the estimation of the propulsive power for a broad range of vessels.

The text of this volume includes published data for the resistance of the ship's hull and performance of the ship's propellers n order to enable the practitioners to make proper predictions of the ship's power on the basis of the materials and data contained in it. The authors have also included numerous illustrative worked examples to demonstrate the practical applications of the subject data as well as powering methodologies.

The publication is mainly aimed at a very wide readership including practicing marine engineers and naval architect together with the sea-going officers and craft designers, plus of course under- and post-graduate students of all above listed disciplines.

SHIP COLLISION DAMAGE

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.

VIBRATION

Several quite significant technical developments and achievements have been accomplished in the area of ship hull vibration during past couple of decades allowing for serious improvements in the technologies for design of ships through avoidance of the excessive hull vibration. The present volume has been specifically designed to deal with the most important technical of the vibration of hull.

This book is opening with the intro section that provides designers with the general info and also basic definitions. The second section is dealing with the theory and concepts of vibration, including the continuous and discrete analysis together with the underwater radiated noise and ship propeller exciting forces. The third section of the title mainly covers the analysis and design issues including basic considerations plus design approaches, added mass and excitation of the diesel engine/propellers, stiffness of foundation of the main thrust bearing, approximate evaluations governing the natural frequencies of the superstructure, cavitation noise etc.

The last section of the volume covers the criteria of vibration, its measurement including design verification and corrective investigation, and post-trial corrections including both hydrodynamic and structural modifications, propeller change and determining the model constraints. Very useful title for all ship designers.
