The present report is the first one in a series focusing upon the seafarers training relating to the introduction of the shipboard technologies and universal introduction of the AIS providing an excellent chance to perform the observation of the whole extent to which such training is accompanying the intro to the newly established onboard technologies.

Before the interviews with the seafarers have been conducted related to the training accompanying the AIS introduction, the authors of the preset volume has attempted to duly ascertain the level of the errors commonly identified and concerned with the information that is being transmitted using the AIS and treated this as a sort of the indicator of the seafarers competence.

The whole content of the report has been compiled on the basis of the data collected in the four-year period and it is intended to indicate the level of the errors made when using the AIS. The authors have also considered the extent to which subject system encourages the incorrect use of the VHF radio to avoidance of the collisions plus the implications of the subject factor for the training. The utilization of the VHF radio for negotiating of the collision avoidance between the vessels was considered a serious problem for long time and by numerous agencies dealing with the navigation...

Under the new IMO performance standards relating to the shipboard radar equipment, all of them shall now be capable of displaying the AIS information; the term ARPA, in term, is planned to be replaced with the TTD, standing for the target tracking device. Nowadays, a broad range of such devices is available, and the personnel involved in operation of this equipment, shall be provided with the familiarization training at the time of the boarding, and such training shall be equipment-specific.

The present booklet shall accompany this video training film and is mainly intended to be used by the navigation officers to train the cadets and also to be used by all other people on board to get familiarized with the main issues related to the target tracking as applied to the collision avoidance. Maritime radars enable the vessels to pinpoint other ships and to locate the own position of the vessel relative to the landmarks.

The working principle of the radar consists of sending the beam radio wave pulses and amplification, processing and further displaying of the returning echoes - this allows the radio operator to "see" the ships which would normally not be visible due to the mist of fog, or lack of lighting. It shall be noted that the echoes from some targets may not be strong enough and therefore not display while other objects may be obscured...

Marine radar is considered a must-have piece of shipboard radio equipment necessary for the safe navigation of the vessels; such radars are also carried even by many leisure crafts on voluntary basis, with VTS, standing for the vessel traffic services, and this equipment is truly indispensable to the safe and effective operation of the major marine ports and harbors; in addition, this equipment has some other important maritime applications.

The present volume will tell the readers how marine radars detect the targets. The content starts with quite brief historical overview to explain the way contemporary practice has developed from the original faltering steps of the past times. The authors have described and illustrated the modern marine radars together with both active and passive beacon targets.

As we know and as it has been discussed in this publication by Videotel, operation of the marine radar relies on the ability of various marine objects to return the echoes, and the authors have examined subject ability in theoretical and practical standpoints. The have also included the full technical analysis of numerous real life factors such as the environment and the weather plus the radio operator's ability to set the required controls. All efforts have been made to be comprehensive and to minimize the need for any other references.

The main aim of Ashley Waite, the practicing engineer and author of this excellent and very useful volume, was to provide all other practicing engineers with the source of information that would help them to understand the fundamental working principles of sonars and also to let them develop the formulas and so-called rules of thumb for the design and performance analysis of subject equipment.

Having a remarkably long professional experience in design and operation of sonars, the author has managed to use this knowledge providing a good practical guidance and working solutions to the various problems most commonly encountered by the technicians and engineers involved in design and operation of the sonars as well as in the performance analysis. The content is arranged in three main parts covering the parameters of the equipment, sound propagation through the sea water and practical sonar systems.

The book is covering all important aspects of sonars and contains numerous useful working examples. The readers are not expected to have any serious knowledge of sonars because the way of explanation is very clear and easily understandable even to the beginners, with no math or physics background required. The end-chapter exercises provided with the correct solutions have been included for the self-assessment and tracking of the training process. The book will be an excellent addition to every engineer's library.

The last years have shown significantly increasing attention paid to the MTS, i.e. maritime transportation systems; the industry focused on efficiency and safety of sea transportation, prevention of potential pollution caused to the environment from ships and also response to the cases of pollution.

The AIS, standing for the auto-identification systems, were originally developed to be a response to all above mentioned concerns, and huge work attempting to define the technical/communication requirements applying to such systems. Those efforts have finally resulted in development of the worldwide carriage requirements for the systems aboard all ships as per the SOLAS Convention, as necessary.

The present report addresses the shipboard display of the information. Considering insufficient amount of the recognized standards and requirements applicable to such display, the USCG did request NRC to examine both technical and human factors. The efforts were made to include proper assessment of the current AIS technologies together with the evaluation of the system designs and capabilities. The committee was originally expected to consider the potential impacts of the changes in the technology, economics, security plus various operational considerations plus human factors, operational environments, technical integration, international standards and other relevant matters...

The main content of the present training course was developed under the RoNoMar standing for the "Romanian-Norwegian Maritime Project" and starts with a Glossary of terms/abbreviations used within the publication and industry in general. Radio is considered a basis of all safety and distress systems that are in wide use by the vessels at sea since the initial instance of application of the radio-technology to save the human lives at sea back in 1899.

The radio technology has soon been realized to be very effective and the distress-and-safety system based on the radiotechnology was established in the internationally recognized regulations and rules governing the types of the equipment and frequencies used, together with the established operational procedures.

The book starts with the introduction and theoretical basics of the GMDSS system, followed with the propagation of the radio waves, receivers and transmitters of the waves, safety and distress communications, telex procedures, DSC, radiotelephony and Inmarsat, MSI, terrestrial distress communications, SART, EPIRB, power supplies and general radio-related regulations, traffic charging and antennas, GMDSS frequencies and some additional reference information related to the operators and access codes, antenna positioning etc.
