RESISTANCE OF SHIPS AND SCREW PROPULSION

The author of this classical work developed it with the intention to give students a sort of compact yet informative treatise that would cover all the aspects of the ship hull resistance and propulsion and that would contain all necessary formulae, tables and other data for making correct estimates. His efforts eventually resulted in the present title that gained popularity among students of naval architecture.

There are six basic chapters in this volume, starting with the general information about the hull resistance, where the essentials are explained including but not limited to the eddy and skin resistance, Froude’s and Rankine’s methods, phenomena of waves, trochoidal waves, squat and shallow water effects etc. The second chapter deals with the propellers and provides all important definitions and formulae with proper and easily understandable explanations.

After that, the author proceeds with the analysis of the mutual reactions between ship’s hull and propeller, including the thrust deduction; later, the analysis of trials is given together with the average results. Two other chapters of the publication are devoted to the power of ships and design of the ship’s propellers.

THE RESISTANCE AND PROPULSION OF SHIPS

The main body of this classic publication is arranged in six chapters. The first chapter is dealing with the ship resistance itself, including the general ideas on that and stream lines with their geometry, one of the deeply immersed planes, skin-resistance, wave-making resistance, Froud’s experiments, increase of the ship’s hull resistance due to the shallow and/or rogue water, the influence that the shoals, banks, currents and slops have on the resistance, and other relevant items.

The second chapter is devoted to the ship propulsion, and here such important matters as propellers and their propulsive actions, hydraulic propulsion, screw turbines/propellers etc. , are covered in detail. The objective of the third chapter is to address reaction between the ship’s hull and the propeller, with due attention paid to the constitution of the wake, analysis of the power that would be required for the propulsion of particular ship, indicated thrust, mean pitch and mean slip, negative apparent ship etc.

The remaining three chapters tell readers about the design of the ship propeller, powering ships and, of course, trial ships. Although released more than a century back, the content of the book retails its relevance today.

SUBMARINE HYDRODYNAMICS

The author of this publication has successfully adopted a practical approach and has presented all recent researches and also different practical applications in the real-life design and operation of the submarines. The list of topics covered within this volume is including the hydrostatics and maneuvering of the submarines, and their resistance and propulsion problems.

The author has conducted a brief review of the fundamental technical concepts in ship hydrodynamics and then proceeded to the demonstration of how exactly subject concepts could be applied to the submarines, covering the use of the physical model experiments. He has also clearly explained all issues commonly associated with the maneuvering of the submarine in the vertical/horizontal planes allowing readers to discover the suggested stability criteria, together with the effectiveness of the rudder and also hydroplane.

The publication also is including a separate section covering the design of the hull appendages including all technical info relating to the sail design and arrangement of the bow planes plus alternative configurations of the stern part of the submarine. Among the other topics that have been addressed in this volume we would mention the hydro-acoustic performance, different resistance components and hull shape effect. The content reflects a great experience of the author in this field of submarine design.

CONTEMPORARY IDEAS ON SHIP STABILITY

The ship disasters that occurred in the past all serve as reminders to the professionals of the maritime industry of the serious need for the cost effective enhancement of the safety and also as strong indicators of the gaps existing there in the stability safety of the vessels. The latter problem is actually very complex, and practically meaningful solutions to it can be feasible only in case of close international co-operation and combining the efforts made by all members of the maritime community.

A CRP, standing for the Collaborative Research Project, was launched some thirty years ago as a response to the above mentioned problem. The authors of the present publication have included selected and most valuable technical materials obtained from the first four CRP workshops. The book contains nearly fifty documents representing all currently available professional expertise related to the stability of the vessels, spanning seventeen different countries of the world.

All of the papers included in this volume have been arranged in four groups, dealing with the stability of the intact ship, stability of a damaged ship, covering the special problems of ship stability, and addressing the impact that stability has on design and operation of the vessels. Definitely must-have book for all those people who wish to be kept updated with all recent happenings in the field of contemporary naval architecture, and ship stability in particular.

INTRODUCTION TO NAVAL ARCHITECTURE

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.

CREATING SHAPES IN CIVIL AND NAVAL ARCHITECTURE

The content of this volume is mainly based on the results obtained in the course of the international Workshop which took place in Berlin and dedicated to creating of the shapes in both naval and civil architecture. The authors of the paper are presenting the very final version of the fourteen articles that have been presented at that time together with four relevant appendices.

Subject workshop was intentionally held to lay the certain basics in a comparative study of the history of technical knowledge in two above mentioned disciplines. We know that the naval architecture is treating the conception, design and subsequent realization for the maritime structures. The subject of creating shapes was considered a focal interest point for the comparisons carried out between two above mentioned disciplines due to the important role it plays in development of the objects.

The discussions and presentations that took place during that workshop and then included in this volume in the form of results are following such objectives as collection and documenting of the sources of shape creating-related knowledge, classification of the procedural and practical knowledge, enumeration of the important milestones, placing priorities related to the design and construction of the objects, relevant historical changes, comparison of different styles and methodologies of shape design, terminology, real life case studies etc.

SHIP RESISTANCE AND FLOW

One of the most serious problems of contemporary naval architecture is the correct prediction of the resistance of the newly developed designs at the earlier stages of the project. At the time of the ordering of the new vessel, a contract that contains the technical specification is signed between the yard and the future ship owner. Among the most important specifications is the contract speed of the ship, i.e. the speed attained to the particular power consumption during the sea trials carried out straight after the delivery.

Subject trials are supposed to be carried out under the ideal weather conditions. However, in the real life numerous corrections have to be made to the influence of the various environmental factors. In case corrected speed of the vessel appears to be lower than the one specified in the contract, the shipyard will have to pay a penalty to the ship owner, and this penalty will mainly depend on the difference noted between the contract speed and the speed achieved during the trials.

And, should this difference be too large, ship owner may even refuse to accept the newly built ship. This volume covers all aspects of the ship resistance and flow, including the governing equations, resistance decomposition, types and proof of similarity, flow around the ship hull. experimental prediction of the hull resistance and its numerical prediction and others.
