Lagrangian Analysis and Prediction of Coastal and Ocean Dynamics

   This volume has actually been motivated by the very recent surge in the availability and density of Lagrangian measurements as well as latest math and methodological developments in the field of analysis of the relevant data in order to improve the characteristics of the circulation models and many applications to dispersion of various biological species. One of the main intentions of the present publication was to conduct a proper and thorough review of Lagrangian observations, as well as  the applicable methods of assimilation and analysis in both biological and physical oceanography; it is also intended to present some of the brand new methods of subject analysis and assimilation of the data, plus applications of the stochastic models from the studies of biological dispersion. Some of the chapters of this book have been specifically prepared while others had been presented at various LAPCOD workshops. In fact, this work may be considered a very first of its kind due its core topic being the Lagrangian point of view applied to the studies of the transport phenomena in the oceanic flows. Anther interesting and valuable aspects of this volume is the multi-disciplinary nature plus the contributions provided by the theoreticians and experimentalists and other professionals from very diverse fields, from marine biology up to the mathematics.

Intraseasonal Variability in the Atmosphere-Ocean Climate System

   The process of provision of improvement in the reliability of long-range forecasts of severe weather and floods, droughts and other natural disasters, is critically important to the livelihood of the mankind, especially of millions of humans who can be potentially affected by such events. The proper understanding and correct prediction of the ISV, standing for the intra-seasonal variability, is considered crucial to the improvement of the associated forecasts and also the reliability of the projects related to the climate changes through the corresponding climate models. This second edition of the volume has been significantly updated, numerous original chapters have been re-written while some new chapters have been added covering the new developments in the field of the ISV research. In the introduction to the initial edition of this classic volume, the authors have written about their goal to provide readers with the reference text on ISV with the intention to fill the existing gap between the climate predictions and weather forecasts. And in the present second release of the book the authors, William Lau and Duane Waliser, seek to further this serious goal. Absolutely recommended publication for any professional in meteorology and actually anyone with the interest in this field.

Alert - Issue 18 - Health and Wellbeing

   Another release of the Human Element bulletin, and this one is dedicated to the health and wellbeing of people who are working at sea. Since so many of the systems on board ships are dependant on human involvement to some extent, we need to consider this link as a potential frailty that requires to be under periodic monitoring and management. It is very important to keep the mariners healthy and happy since this will definitely result in the safe and commercially efficient of the vessel. In the fourth article of the MLC Convention it is emphasized that every seafarer is entitled to the right of working in a safe and secure working place complying with the applicable recognized safety standards, as well as to fair employment terms, decent conditions of living and working on board, protection of their health, and other forms of protection. It means that the owners and managers of the ships are obliged to provide their employees with secure and safe working place, and comply with the requirements of all relevant regulatory documents. This can be done through encouraging of the safety culture and security awareness, provision of adequate benefits to the employees, establish and maintain the working policy of openness and good communication, and everything else that is required. The present issue of Alert is supplemented with this short training video.

Alert 18 - Health and Wellbeing

   Suppose the ship was completely automatic - no seafarers required, suppose the engines maintain themselves - no people required, and suppose all the cargo did load and discharge itself - untouched by human hands... Unlikely? Well, of course, it is. Technology may be playing an increasing role in the running of the vessel, but as we all know, how safely and how efficiently the ship is run, is all about people - and so is this issue of Alert. The plight of some seafarers has already been made international headlight. Badly paid, sometimes not paid at all, poor food and accommodation, working on ships managed by people having little or no regard to health, safety and wellbeing. The MLC 2006 is described by many as a milestone for the international maritime industry. Often referred to as the "seafarers' bill of rights", it addresses the significant issues pf minimum working age, maximum working hours, along with accommodation, health protection, food and catering, medical care, welfare and also social security matters. The Convention is also addressing the current health concerns, for example the effects of vibration and noise on seafarers, and is intended to apply worldwide, be easily understandable, and easy to update and enforce. This video supplements the Alert 18 issue.

The Dynamic Method in Oceanography
   More than a century ago, B. Helland-Nanses and I. Snadstrom and proposed a method of computing the ocean currents on the basis of the water density distribution. Later, this method became known as the dynamic method for computing elements of the ocean currents, or hydrological data analysis method. This is the indirect method and fully bases on the theoretical assumption that the coriolis force and horizontal pressure gradient are in equilibrium in the steady state below the mixed layer of the ocean surface. The velocities of the current are calculated by means of the dynamic method. The present volume is the author's attempt to properly justify the method referred to above, theoretically and also to shed some light on the nature of currents calculated/computed using this method. It also examines the importance of the depth of reference surface and the accuracy of the computations. In addition, the book contains the descriptions of the structure of the gradient component of a wind-driven current velocity. However, the author of the title does not attempt to provide a thorough treatise on the method in question, but is rather trying to analyze some of the important aspects of the theoretical principles of the dynamic method together with the possible practical applications, using the ocean currents theory.

Marine Acoustics - Direct and Inverse Problems
   The publication was released to present the ongoing trends in the scientific researches related to the underwater acoustic wave inverse/direct problems. We consider the "ocean-seabed" system an acoustic wave guide, and in fact this volume is the only one treating the inverse problems. The authors of the title treat the acoustic wave propagation for different seabed types and consider the direct/inverse problems in realistic environments of the ocean. They have emphasized the computation of the Green's functions and have added some completely new material relating to the poro-elastic and elastic types of seabed. They have also addressed numerous areas of the practical interest mainly relating to the underwater acoustic imaging, covering the ecological cleanup and surveys, means of protection of the open-water harbours, proper maintenance of the offshore oil-and-gas enterprises, together with other relevant and important areas of concern. It shall be treated as an excellent math treatise. The book will be very useful because of the information contained - note that the waveguide inversion problems are not actually addressed in too many reference books and this book is also intended to fill the gap in the information with this regard, with particular attention paid by the authors to the forward scattering problem.

Wave Energy Conversion
   The energy of ocean waves and of the renewable energy resources provides quite small but still significant proportion of the future energy needs without adding to global warming and also pollution of the environment. The present concise and very practical reference book prepared by John Brook describes several alternative methods of application, and also sheds the light on the technical concepts standing behind the conversion of the waves energy; the author has also investigated the wave power activities all around the world. The volume presents the exploration of the potential of the energy that can be obtained from the ocean waves - historically, this source of energy is well known for its great destructive power and strength. However, as you will see from this book, this source of energy can and shall be converted into useful work. Of course, some of the methods of conversion are still under development but there is some significant progress and subject systems will most probably be introduced soon. The issue is that the cost of energy obtained using these methods, remains relatively high; however, they are expected to come down quite considerably, bearing in mind that the experience is growing. It is anticipated that this type of energy eventually replace or at least supplement significant portion of conventionally generated energy...

Fate and Effects of Oil in Marine Ecosystems
   The publication contains the proceedings of the international conference dedicated to the marine pollution by oil. Man has always influenced the surrounding environment, but at the very beginning the traces of people's activities were almost not noticeable and the effects of those activities to the equilibrium of the eco-system were not serious at all. As soon as the human started to use the tools, people were able ti influence their surroundings in much more drastical way, and that is actually the time when the things started to go wrong. The environment condition we have today is the result of people's activities. The first section of the title is dealing with chemical/physical behavior of oil in marine environment and with the associated biological processes, while the second chapter addresses the effects of oil and its compounds on the eco-systems, populations and species. The third section of the volume provides readers with the results obtained during the monitoring of both biotic and abiotic compartments of marine eco-systems. And the fourth section is dedicated to the several specific cases of the risk management and analysis on the basis on existing scientific technical knowledge. Definitely recommended title for those willing to be up-to-date with all happenings in the field of marine science.

Marine Science - The People Behind The Science
   The world ocean covers more than seventy percent of the Earth's surface, so-called "the blue planet". More than ninety percent of the living space of the Earth is accumulated in the ocean waters and until half-billion years back, literally all forms of life existed there. The global health of our planet together with all its inhabitants seriously depends on the water cycling and nutrients and minerals carried by the water. The oceans of the world have always influenced the weather and climate patterns. The relationship between the sea and the human began in ancient times when lack of technology significantly limited people's ability to explore the ocean waters. There are many economically valuable resources that are acquired from the seas, and the scientists in the field of marine science and oceanography have also revealed the insight into the very origin of life to study the reproduction and development of the organisms and various geological processes. The term "marine biology" covers numerous sciences all relating to the sea, for example marine biology and oceanography, marine chemistry and others. The present title tells the readers about the prominent people who made the marine science, from Sir C. Wyville Thomson to Robert D. Ballard. In addition to the chapters dedicated to these people, there is also a glossary of terms.

The Science of Ocean Waves
   This book written by famous scientist and professional astronomer J. B. Zirker is dedicated to the ocean waves, including tsunamis, stormy ocean waves and ripples, and the book is aimed at any interested persons including surfers and ocean scientists. The book is very hard to put down. It presents a very fascinating reading for them and is considered a great one for the oceanography classes, especially at undergraduate level. The author has provided an up-to-date and quite comprehensive account of the matters whose complexity is commonly very hardly appreciated by non-professionals in the field and non-scientists. The deep insights, comprehensive narratives and historic perspectives included to the publication do not contain any single equation and presence of graphics has been kept to a minimum, making the volume very reader-friendly and being the reason why the title has been recognized as a very remarkable achievement. We would say that this book may already be used as a standard textbook for the ocean as well as weather forecasters, scientists, plus climate modelers and students. The author has applied a very fresh look to the ocean waves and also provided the theory with numerous illustrations to make the content more accessible for everyone.

A Guide to Contingency Planning for the Gas Carrier Alongside and within Port Limits

   The main purpose of the present guide is to provide a thorough reference which might be useful to various port authorities as well as operating management of LNG carriers and terminals in reviewing or developing their planning in order to avoid the accidents or at lease reduce their possibility. The publication would also be quite helpful in controlling the possible consequences of such accidents happening within the port limits. This second (revised) edition takes into account the STCW Convention and SOLAS IX as well as the ISM Code. It covers ships in transit and operation, ships alongside, public relations and periodic review. Note, however, that the present publication shall not be treated as a comprehensive technical manual on contingency planning since the authors have confined this document to the aspect directly relating to the carriage and handling of gases. The circumstances influencing the contingency planning may vary from port to ports in the matters such as nautical/weather considerations, types of cargo being handled, authorities etc. When preparing this document, broader interpretation of the term "contingency planning" was taken, including considerations related to the accident prevention and control of possible consequences.

A Contingency Planning and Crew Response Guide for Gas Carriers Damage at Sea and in Port Approaches

   The present Guide would mostly be applicable to all liquid gas carriers both at sea and approaches to the ports; it has been released by the working group with the assistance from members of OCIMF, ICS, SIGTTO and ISU aiming to provide a thorough reference that would be useful to the operating managements of gas ships in reviewing or developing their contingency planning. The contingency plans supplement the SOPEP required for all ships >400 GT as per the Annex I to MARPOL. Regardless of how the liquefied gas is carried (pressure/temperature being meant), the cargo containment shall not be treated as part of the vessel's structure. Such containments are in all cases located inboard of the vessel's side plus above the bottom. The big portion of this booklet has been taken from the CPD (contingency planning document) that have been formulated by the managing teams of a number of companies within the shipping industry. The present guide is mainly addressed at the ship operating companies  and assumes some general understanding of the cargo characteristics as well as of the design, construction and, of course, operation of the gas carrying ships. Definitely useful publication not only to the managerial stuff but also all personnel.

A Justification into the Use of Insulation Flanges at the Ship-Shore and Ship-Ship Interface

   The purpose of the present SIGTTO publication is to provide a proper explanation of how insulation flanges protect from ignition caused by arcing. It contains information on the inductive circuits, electrical characteristics of the cargo transfer hoses together with the supporting calculations, some examples of the effects of hose inductance and resistance, information on the effect of capacitance, testing of the flanges and multiple loading arms and parallel circuits, all supplemented with the list of definitions and conclusions and recommendations. The insulation flanges have been used for several decades; their effectiveness is sometimes seriously challenged, though there have been no reported fire incidents on the manifolds installed on board of tankers or gas carriers. This shall be taken into consideration by the ship operators having a background of road tanker operations, supplying the LNG as fuel oil. Since this document mainly concentrates on the protection from arcing-caused fires, we would definitely consider it very important and recommended to everyone involved in such sort of operations as the info provided in the booklet might help in improving the operational safety.

Report on the Effects of Fire on LNG Carrier Containment Systems

   Current LNG transportation practice provides for pressure relief systems, designed with credit for the tank's insulation in order to to prevent gas cargo pressurization due to boil-off and fire, as per IMO IGC Code 8.5. However, it is uncertain to what extent any insulation degradation, in a fire situation, is taken into account in the design of PRV systems. As foam plastic insulation materials are subject to possible melting, degradation and/or ignition at temperatures lower than might be achieved during such fire exposure, there is concern that the PRV systems may not be capable of relieving the vapor flows that would result from the increased boil-off due to partial or total insulation failure. This SIGTTO publication covers following matters - the origins of the IGC Code, fire scenarios, LNG carrier pressure relief systems, simplified reapplication of the Code for loss of insulation, heat transfer into the tank; time based heat transfer, response of insulation materials to heat, and others. This is quite useful document providing necessary updates required to be taken into account to organize the transportation, storage and handling of the LNG cargoes in a safe way.

clean seas guide for oil tankers
   The present Guide was prepared and released in accordance with the relevant technical requirements of the MARPOL Conventions and associated interpretations with the intention to be used together with them. Please note however that this paper is not dealing with the requirements related to the construction/equipment. Under the Annex I of the Convention any discharge of oil or oil-containing mixture is prohibited from the oil tankers,  including the mixtures coming from the bilges located in the cargo pump rooms, within a distance of fifty nautical miles from the nearest land. In addition, the flow and concentration, as well as the quantity of the substances discharges anywhere else are also limited. Obviously, the only way to ensure due compliance with these limitations is to adhere to the oil retention procedures. Those procedures would typically involve the collection and separation of any oily waters appearing as a result of tank cleaning/ballasting operations. These mixtures are to be accumulated in a special tanks to be subsequently disposed of somewhere ashore. This volume is mainly concerned with these procedures and their application; the information contained in this document will be of great importance and practical use to the crew members as well as to all other personnel involved in the above stated operations.
