Submarine motions at a near-surface depth under irregular ocean waves

This research aims to study the seakeeping behavior of a submarine close to the sea water surface. At the depths close to the sea level, the submarine experiences the effect of ocean waves. Due to these dynamic effects, small and medium submarines cannot perform the snorting operation in rough and stormy sea properly. This study is based on the numerical method. For verification of the results, some experiments are carried out in the towing tank of the Admiral Makarov National University of Shipbuilding. As a result of this study enabling the small and medium submarines to navigate and snort in rough ocean waves, the unique innovative system “Moon-Korol” is presented as a new patent.
