Abstract
According to the Convention for the Safety of Life at Sea and International Convention on Maritime Search and Rescue, saving human lives at sea is the duty of all signatory states. This paper analyzes and gives an overview of previous research activities in search and rescue system at sea and how the use of unmanned aerial vehicles (UAV) can improve search and rescue actions at sea. Research activities include development of the search system and placement of resources that are used in search and rescue actions (ships, planes etc.). Previous research is mainly related to minimizing response time when accidents at sea are detected in relation to search and rescue missions. Implementation of unmanned aerial vehicles into the search and rescue system enables improvement of these actions due to earlier detection and verification of accidents at sea and prevents unnecessary search and rescue units engagement in cases when an accident did not occur. The results of previous research point to the fact that future research should aim to explore the synthesis of unmanned aerial vehicles with the existing search and rescue system at sea in Croatia.
Highlights
According to national and international legislations, giving aid to people in life-threatening danger is the duty of all signatory states of the International Convention on Maritime Search and Rescue, including Croatia
Until present, improving maritime search and rescue (SAR) systems when identifying persons in distress meant increasing the number of marine rescue units (MRU), which meant high financial costs when buying those units as well as engaging the crew that operates them that is in danger while searching the area when confirming the accident or finding persons in distress
Considering the fact that at a sea temperature of 4.5 oC a person can survive in water less than an hour, guidelines for SAR system development are directed to minimizing response time of Search Rescue Units (SRUs)
Summary
According to national and international legislations, giving aid to people in life-threatening danger is the duty of all signatory states of the International Convention on Maritime Search and Rescue, including Croatia. The purpose of this paper is to make an analysis of previous research related to maritime SAR systems, examine the advantages of the use of UAVs in SAR actions at sea as well as trends in future development of the subject area. It can be assumed that the available technical solutions in the form of unmanned aerial vehicles are financially acceptable and enable quick and easy application in SAR actions. It is Promet – Traffic & Transportation, Vol 31, 2019, No 2, 205-212. Assumed that these are the main advantages of using this technology and that it would be beneficial to both SAR and persons in distress
