Water Waves and Ship Hydrodynamics

   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.

Ice Induced Resistance of Ship Hulls

   The global warming and exploration of the hydrocarbons that is carried out in the Arctic region results in the constantly increasing maritime activity in iced waters. Nowadays, it is possible to predict if a ship will be capable of surviving an encounter with the ice of a particular given thickness; however such knowledge will not be enough to accurately predict the associated increase of the fuel costs. In the present thesis the investigation of the validity of the analytical formulations for the ice resistance in the above mentioned geographical region has been performed. Subject formulations have been based on the trials in the Swedish-Finnish waters having lower salinity and relatively warm climate in comparison to the ones of the Arctic waters. This has been conducted by comparing the ship resistance that is estimated on the basis of the information obtained from the onboard measurements of the ship's speed and thickness of the ice as well as the engine power with the estimates received from the analytical formulations. The topic addressed in this book is very challenging and rewarding. The thesis starts with the introduction followed by the description of the characteristics of the sea ice, models used for the calculation of the ice induced hull resistance, open-water resistance, analysis of the relevant statistical data, and many other important aspects.

LOAD AND GLOBAL RESPONSE OF SHIPS
   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...

   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.
