Abstract

Maritime traffic has always played an important economic, strategic and transportation role for a maritime country. Small vessels, considering total maritime traffic in the Adriatic Sea, play an important role, although their numbers are often not considered as a potential security risk. Although small vessel accidents do not have damage potential as the large ones, they still need to be regarded as a significant risk to safety of navigation. The first part of this paper shows, thru analysis of SAR action statistical data, that the total number of all accidents is dominated by accidents involving small vessels. A particular problem in the maritime traffic monitoring is the fact that small vessels, because of their characteristics, have a reduced detection probability by modern monitoring technologies and as such can be used as a non-traditional security threat. With development of electronic and information technologies, sensor systems, remote sensing and detection systems, as well as global satellite systems, and the introduction of a legal requirement of AIS on board ships, maritime traffic control has become easier, more organized and more reliable. Although application of these technologies has brought some progress in maritime traffic monitoring, small and fast vessels that are not equipped with AIS system can still be relatively unnoticed in all increasing maritime traffic. For this reason, a solution is perceived in the integration of radar, satellite and electro-optical technologies. The conclusion of this study represents one maritime traffic monitoring possibility that could be a step towards increasing the detection probability of small vessels.

Summary

Introduction

Maritime transport on the Adriatic Sea records constant growth each year. traffic of ships larger than 300 BT has a major role in a maritime traffic, from the perspective of the Croatian part of the Adriatic Sea, a higher security risk represent small and fast craft in the context of non-traditional security threats. It is necessary to integrate existing technology with new upcoming technology for the purpose of more qualitative and comprehensive maritime traffic surveillance, control and supervision, with the main aim to prevent maritime accidents and minimize security threats. The first part of this paper will focus on current situation in maritime traffic and undertaken SAR operations in recent years with special emphasis on small boats. It should be noted that overall situation presented in this paper is applied to Croatia that is to the eastern coast of the Adriatic Sea. the paper will discuss non-traditional threats and challenges that they bring in the modern maritime transport. The second part of this paper will deal with the contemporary maritime traffic monitoring systems and their integration for better small vessels monitoring and detection capabilities. Komorčec et al / Scientific Journal of Maritime Research 30 (2016) 3-11 are subject to the laws, rules and regulations of international character, yet manage to pass unnoticed by contemporary maritime traffic monitoring system
