Authors: Yuriy Dachev, Valentin Zlatev
Abstract: There are actions being taken worldwide continuously to improve the safety of shipping. Nevertheless, sea accidents are not diminishing. According to the IMO SAR Convention, maritime states are required to provide surveillance of the entire coastline under their jurisdiction and to be able to carry out effective rescue operations. The success of the SAR operation depends on the speed of its planning and implementation. The captain of a ship, participating in a SAR operation, must have a clear methodology and criteria, which define the volume of the search. One of the methodologies, offered by the SAR Convention, is ""Expanding Square"". It has weaknesses, one of which is the large area where should be search the object in distress. The article deals with an improved ""Expanding Square"" to locate an object in distress in a minimum area with maximum probability of detection. The proposed methodology provides better opportunities for recalculating and repeating of the search and a high probability of discovering the object.
