Abstract
Currently, globalization of the world economy has also resulted in a shipping volume increase. However, this growth in maritime traffic has led to increased risk of marine accidents. These accidents have a higher probability of occurring in regions where geographical features such as islands are present. Further, the positioning of rescue ships in a particular ocean region with a high level of maritime activity is critical for rescue operations. This paper proposes a method for determining an optimal set of locations for stationing rescue ships in an ocean region with numerous accident sites, such as in the Wando islands of South Korea. The computational challenge in this problem is identified as the positioning of numerous islands of varying sizes located in the region. Thus, the proposed method combines a clustering-based optimization method and an image processing approach that incorporates flood filling to calculate the shortest pixel value between two points in the ocean that detours around the islands. Experimental results indicate that the proposed method reduces the distance between rescue ships and each accident site by 5.0 km compared to the original rescue ship locations. Thus, rescue time is reduced.
Highlights
90% of the world’s trade is conducted by sea, and the volume of cargo and the number of ships entering and leaving ports continues to increase with economic growth [1].Concomitant with this growth in maritime traffic is the increased risk of marine accidents [2].The occurrence of marine accidents is higher in regions closer to shore, primarily because of the increased ocean traffic and the resulting collisions
With a set of accident site locations clustered into three ships in the Wando islands of South Korea, with a set of 429 accident site locations clustered into groups
This paper proposed a method that uses image processing and the flood-filling algorithm to produce accurate minimum distances from rescue ships to accident sites in the presence of intervening islands

This is affected by geographical features such as islands. There is an issue about search and rescue operations for migrants at sea [4,5,6]
