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...
The aim of this technical study is provision of the specific and thorough analysis of all opportunities and of the legal/economic feasibility of implementing the safety due of the navigation, considered a transit charge that should be paid as necessary by all vessels that cross the waters of the coastal States, another aim of the compilers of the publication is to perform a professional estimation of the real contribution of such device to improving the capacities of subject countries in the surveillance of marine navigation, following the decisions of the GTMO 5+5 Ministers.
Among the purposes of this document we would definitely highlights the diagnosis of the systems of the navigation aids, analysis of the real needs (particularly funding needs), operational approaches and legal provisions, and also the possible implementations of the due for the vessels and coastal States, elaboration etc. Six major parts of this study are providing industry with virtually all required info relating to the international legal framework and legal feasibility, services required means/costs, characterization of the due, elements of the benchmark, and impacts. The annexes will provide the terms of reference, the questionnaire plus the actual status of the conventions, as adopted by the GTMO 5+5 members.
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.
