An Analysis of Working Sea States and Operational Ranges for the Gangway Equipped Offshore Wind Turbine Maintenance Vessels

During offshore wind turbine maintenance operations, maintenance vessels typically rely on transfer gangways to achieve safe transfer of personnel from the vessel to the wind turbine. With the development of offshore wind farms toward far sea areas, working sea state conditions have become increasingly complex. In rece...

DQN-Based Operational Path Planning for Autonomous Fishing Vessel Safety in Waves

Developing autonomous navigation systems for small fishing vessels is required to improve path-tracking robustness and mitigate severe wave-induced roll motions. This study proposes a Deep Q-Network (DQN)-based operational path planning methodology that explicitly incorporates roll motion reduction into the reward func...

Design And Development Of An Autonomous Maritime Rescue Vehicle Using Point-To-Point Navigation Method

Man Overboard (MOB) incidents require rapid rescue operations because delayed response significantly reduces the probability of victim survival. Conventional life buoys provide flotation assistance but cannot autonomously approach the victim, resulting in rescue operations that rely heavily on manual intervention by th...
