    Search patterns and procedures contained in the International Aeronautical and Maritime Search and Rescue Manual for Mobile Facilities meet the requirements of theoretical assumptions about search and rescue operations. But the individual manoeuvrability characteristics of a search vessel cause real search and rescue operations to differ from theoretical patterns. This article analyses the difference between theoretical and actual search regions in a Diagram of an Expanding Square Search. Different variants of parameters of ship manoeuvrability have been considered. Some solutions modifying the Diagram of Expanding Square Search are proposed by the authors.

    In this article we proposed a probability map that allows for location of the position of survivors. We used a probability model of a survivor drift to create the map. The model is based on the provisions of IAMSAR containing factors like leeway and wind current. Our proposal of utilizing a probability map diff ers from that shown in the IAMSAR by using other probabilistic methods. We performed analysis of a drifting raft using the Monte Carlo method. The map is closer to reality, since it is asymmetrical and generated by the simulation. However, preparing probability maps might be helpful in SAR action planning.

    Research studies have discussed the correct selection and choice of the optimal units for a specific type of search and rescue task. This article has described the characteristics and properties of merchant vessels that determine their potential for SAR (Search and Rescue) operation. An attempt was made to estimate the suitability of a craft according to its effectiveness and risk. This research may have an impact on improving the organization and coordination of search and rescue operations at sea. The authors have proposed criteria for evaluating merchant units during selection for planned SAR actions. A model for evaluating the suitability of a unit has been presented. It is a mathematical model with elements of expert knowledge. The model classifies attributes, taking into account the lower and upper risk limits and introducing a risk sensitivity factor. The article contains tables and graphs.
