This issue of Alert Human Element Bulletin is devoted to the fatigue, offering some good thought related to the safe manning of the vessels as well as mitigating the most frequently occurring fatigue effects together with the other important risk factors. The content of this issue is expanding the topic addressed within the previously released issue also dealing with the fatigue, and associated video.

The booklet starts with the short guide used for proper interpretation of the main safe manning principles. Human errors have been implicated in most of the maritime casualties. The play major role in grounding and collision cases. This has prompted to EU to conduct thorough investigation of the human factors directly relating to the working conditions and workloads contributing to the shipping accidents.

You will find some results of the subject investigation in this document and this information may help in prevention of such accidents in the future through avoiding the situations that may lead to the fatigue of the personnel and eventually to the serious consequences such as casualties. Since this directly affecting safety of the vessel's crew we recommend you to have a close look in the study.

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.

Suppose for a minute, what if you have been assigned the task to perform the mapping of the general circulation in some completely unfamiliar ocean. The ocean is sub-divided into several basins as well as marginal seas which, in turn, are connected with each others by means of the sea straits. Taking into consideration the possible budget limits for this task, you would most probably choose the sea straits as the starting points for the observation.

To start with, the ocean currents that flow between the basins, over the wide paths that can also be time-varying, are commonly confined to the relatively stable and narrow routes within those straits. Such confinement could result in the profound dynamical consequences, one of them being the choking/hydraulic control; subject process is quite similar to a process by which a dams are regulating the flows from the reservoirs.

Geometry of the funneling may lead to the significantly increased velocities and enhanced tidal modulation, which would in turn lead to the local instabilities, internal bores, plus jumps and mixing, and other events. Shortly, the straits shall be treated as the choke points being dynamically and observationally strategic and containing a broad range of physical processes, all of them being addressed within this book.

The publication of this book is timely - at the time of writing we are in the midst of very troubled times for the dry-bulk shipping markets. Falling demand for dry commodities, an oversupply of ships and a freeze in credit have seen daily hire rates for bulk carriers drop from all-time highs to near all-time lows within the space of a few months.

From freight rates to bunker prices, credit risk to asset values, the financial risks faced by shipping market participants are significant. The book provides readers with a proper understanding of the measurement process and on how to manage the volatility of the freight rate; the information in the book will also let the reader explore the options that are available to the professionals of the shipping industry.



The authors have made a brilliant compilation of the thorough investigation of the markets conducted y the recognized experts. That is why this volume is a must-have for both practitioners and researchers. Their efforts resulted in a truly unique publication combining both theoretical and practical aspects or the risk management, the readers who have gone through the material included in the book will get some essential knowledge of risk assessment and be enabled to understand all major freight derivatives tools.

The present book was specifically prepared for students, practitioners and researchers in the fields of control engineering and marine technology. Taking into account that the audience would be fairly mixed, so much effort has been made by the author to set the proper level of the topic presentation.

Nevertheless, the readers of this book are required to have at least some basic knowledge in linear systems/state space models, say within the limits of one provided at the standard undergraduate control courses. The publication contains four major sections; the first three of them are dealing with the key components of a successful vessel motion control system, namely appropriate math models, proper understanding of the performance assessment, and knowledge of the basic limitations that may possibly affect the desired performance in a negative way. The last part of the book addresses the design of control systems.

Among the topics that have been included in the book there are ship dynamics, wave simulation and modeling, vessel motion performance, wave filtering, design of the control system for auto-pilots and for integrated rudder-fin stabilizer, rol stabilization devices, various models of actuators etc. The book will be useful to practicing marine engineers as well as the academic persons involved in the related research activities.

This publication was written by Tingting Yang and Sherman Shen who made an attempt to cover the constantly emerging networks of maritime wideband communications. The authors are trying to describe to the readers how such networks facilitate the applications like general communications, urgency, maritime distress etc. This book was initially intended to provide a good insight to the scheduling of the maritime data transmission and to the protocol design for the network that has been mentioned above.

The book starts with some brief intro to the networks including their principal architecture, framework and operation principles, and it also includes a survey on current developments in this area. The next part of the book will present the resource allocation as well as the scheduling for the video transmission with the aim to maximize the weights of the video packets being uploaded and transferred. The duet of authors are also proposing an energy and content-aware scheduling scheme for better packet throughput.

Basing on the real vessel route traces received from the navigation programs, the results of the simulations are demonstrating the true viability of the schemes proposed. In addition, the conclusions and valuable suggestions for the future researches have been discussed in this book...

All articles of the International Conference, RINA. One of the ways how the human element makes an impact on a large scale is through inclusion of ergonomic requirements in the Rules published by Classification Societies. This can usually be achieved by either introducing these specific requirements into the Classification Rules or by making the existing Rule requirements with human element implications more explicit.

However, surveyors who assure Rule compliance, often have quite poor or even no any knowledge of the human element... The present pack contains numerous papers presented during the International Conference held in 2011. It starts with the paper describing the human element competency that is required for design appraisal, followed by the documents covering the human factor role in the investigation of marine casualties, human factor design, extended simulation runs and performance of seamen, noise effect on human performance, performance and fatigue issues in bridge and ECR watchkeeping, perception of risk, mapping of work areas, habitability assessment, shock mitigation seat test/evaluation, marine ergonomic design enhancement though digital human modeling, crew innovation on board short-sea vessels etc.
