The content of this volume was written based on the decades of experience of the author as well as his years of lecturing in the university. Since the subject lectures were left unpublished for so many years, the decision was made by the author to compile this perfect book and provide all information and knowledge needed by and useful to the students, in a single and comprehensive volume.
All of the calculations are duly explained in a way making them understandable to the students at all levels. The content is divided in three parts, the first one dealing with the areas, volume, and center of gravity, giving some very general considerations on the subject. The second part of the book is devoted entirely to the ship calculations. The third part addresses the strength of ships together with all associated calculations.
As you can see, the publication was released more that a century back. However, it is still recommended to the students, due to the fact that the theoretical basics of the ship design and construction have not changed. And, the explanations given by the author in his work are somewhat more clear and easier to follow, understand, and apply than the ones in the books being released today.
This is a quite compact but very informative and useful publication providing clear explanations of the shear forces acting on the ship hull and the bending moments resulting from that. The subject definitions actually form the basis of the ship mechanics and lay in the foundation of any strength related calculations. That is why it is critically important for the ship designers and shipbuilders to have good and thorough understanding of them.
Written by the professional captain, the document will be of great use for the people who are not involved in ship design, but rather for those in need of having general understanding of the topic. As we know, the shear force is the one tending to shear, or break, a beam perpendicular to the major axis of that beam. For the purpose of the relevant calculations, the hull of the vessel is normally considered a beam.
The bending moment, in turn, is a sum of all moments that try to alter the beam’s shape. When the vessel is afloat, resting on the surface of the water, the longitudinal deflections will be experienced by the hull; they are caused by the uneven weight and buoyance distribution along the hull length. The subject stresses are always there regardless of the ship loading, and cannot be avoided.
Over the past decades, the members of the Ship Structure Committee have collected and analyzed extensive service cases of the unsatisfactory vessel designs concerning their structural part. The material contained in the document is intended to help the ship designers, including both naval and commercial ships, to specify the cost effective and technically sound details. The details provided in the pages of the present guide combine the service experience with the costs of fabrication.
There are also many data tables, diagrams, pictures and other supplementary materials intended to help the ship designers when selecting the appropriate details of the structure. First of all, the authors provide a brief overview of the sample failures of the ship structures, structural tolerances and material fatigue, as well as general philosophy of the ship design.
The performance of the details is covered in the separate chapter, followed with the information on the estimated man-hours needed for the fabrication. Several practical recommendations conclude the main part of the guide. There are also three appendices with the additional information making the guide even more useful.
The world famous Titanic was considered by so many people, including the professional ship designers, naval architects, and shipbuilders, to be an absolutely unsinkable vessel. Featuring the efficient and redundant shipboard safety systems based on the very latest technological achievements of that time, the vessel was not even considered to possess a full complement of the lifesaving appliances.
As we know, the sad truth is that her maiden voyage resulted in a collision with the iceberg leading to the loss of thousands of people including passengers and crew members. This catastrophe is deservedly treated as one of the most tragic maritime disasters in the history. The author of this book wanted to analyze the entire project of building this ship, from the design stage and up to the launching, to reveal and show the compromises that were made at the beginning of the project, eventually resulting in the flaws.
One of the features of this publication is that it will be equally interesting to the ship designers and the IT people since the author made every effort to show how the lessons obtained from this catastrophe could be applied to the various IT projects, as it happens that the designers claim and think they have launched a truly perfect solution…
The team of authors of the present book, consisting of four world recognized industry experts, has managed to reach the ultimate declared goal, namely to demonstrate the readers the condensed technical experience in designing the ship hull structures looked from the practical point of view.
The content of the volume is arranged in three separate parts presenting the fundamentals of the design, as well as the design theory and its application to the ship hulls. The topics covered in the publication have been treated very comprehensively with a strong emphasis made on the reliability and efficiency of the ship hull structures.
The authors of the book have introduced their own experiences with the dramatically increased ship hull sizes. In addition to the above, they have introduced the vessel types with a highest possible degree of specialization.
The authors have also performed an analysis of the early failures of those "new" hull structures in order to provide the informative illustrations showing why the design of the structures should be conducted on several levels to ensure that the proper loading has been applied and also to make sure that there is an absolutely clear understanding of the behavior of the local structures. An indispensable training source for the students in ship design and construction as well as the practicing engineers and designers.
The present volume continues the book devoted to the large floating structures available here at our website. It will provide the readers with a truly comprehensive and professional treatment of subject structures analyzed together with their relationship with the sea habitats, coastal waters, current flow, and taking into consideration all aspects involved.
The author has looked into the structural and hydro-elastic analysis of the structures at both cell and overall levels, maintenance system, commonly used anti-corrosion arrangements, breakwater analysis and design matters, wave properties that are considered critically important for the correct estimation of the loading of the very large floating structures; note that it is also covering virtually all latest developments in the field with the primary emphasis made on the Mega-Float.
The content has been very well illustrated with the informative and clear pictures, and supplemented with the numerous detailed drawings; there are also equations included for the math modeling and analysis. The book will be ideal for the design professionals and students of structural engineering.
The risk-based design of vessels is a newly established engineering area attracting more and more interest of the practicing designers, engineers and researchers from the various disciplines connected with the design and construction of ships, their operation and regulation.
There is a twofold motivation to use the risk-based approach - the implementation of a novel design considered safe but not yet approved or rational optimization of the existing design focusing on the safety but bearing the performance and efficiency in mind.
The content of this book derives from the information and technical knowledge obtained during the SAFEDOR project coordinated by GL. It is not the intention of the author to prepare a text-book for the ship design students noting that the contributors to this volume are still evolving. However, the volume is aiming to provide readers interested in the risk-based approaches to the ship design with a good understanding of the basic and details of these approaches and their integration.
The volume will facilitate the transfer of the knowledge gained in the course of the project to the whole maritime community and shall therefore be treated well since such transfer will play a very important role in improvement of the ship design techniques and eventually contribute to the safety of shipping.
This volume is elaborating on combination of the basic theoretical approaches and common practices of the preliminary design of the ship. The intention of the author was to support the introductory training courses of ship design as a textbook. Taking this into account, we may consider this book as so useful one to students of naval architecture as well as of all related disciplines.
We are quite sure that the book would actually serve as an excellent reference source not only for the students but even for the practicing naval architects, ship officers, marine engineers and anyone interested in ship design theory plus practical methodologies applied to the estimation of the ship's basic properties and main dimensions together with the other elements of design.
There are five appendices complementing the main content of the book providing some additional information on the different ships types and their characteristics, historical background, regulatory documentation, description of the relational method, etc. Definitely recommended reading for both professional and future ship designers who will benefit from the thoroughly prepared information provided in the volume.
