Development of Onboard Decision Supporting System for Ship Docking Operations
Zhao, Luman; Li, Guoyuan; Knut, Remøy; Wu, Baiheng; Zhang, Houxiang (Chapter, 2020)Maritime operations inevitably influenced by the wind, wave, sea currents, or other perturbations at sea. Providing decision support for these operations based on historical and real-time data of ship status is thus of ... -
Global and Local Awareness: Combine Reinforcement Learning and Model-Based Control for Collision Avoidance
Zhao, Luman; Li, Guoyuan; Zhang, Houxiang (Peer reviewed; Journal article, 2024)In this research, we focus on developing an autonomous system for multiship collision avoidance. The proposed approach combines global path planning based on deep reinforcement learning (DRL) and local motion control to ... -
A human-expertise based statistical method for analysis of log data from a commuter ferry
Wu, Baiheng; Li, Guoyuan; Zhao, Luman; Hildre, Hans Petter; Zhang, Houxiang (Chapter, 2020)The proposed method in this paper aims to better understand the log data from the commuter ferry. By the method, the mechanism of how the human expertise operates the ferry can be found, and thus help to establish ship ... -
MPC-based path planning for ship collision avoidance under COLREGS
Zhu, Mingda; Skulstad, Robert; Zhao, Luman; Zhang, Houxiang; Li, Guoyuan (Chapter, 2022)In recent years, maritime operations have become more technologically demanding due to the more complex working condition and stricter safety requirements. The need to improve the performance of human-machine cooperation ... -
Multi-ship collision avoidance control strategy in close-quarters situations: a case study of Dover Strait ferry maneuvering
Zhao, Luman; Li, Guoyuan; Zhang, Houxiang (Chapter, 2020)Multi-ship collision avoidance is challenging in busy waters like the Dover Strait. Usually, ships follow the rules for avoiding collisions which are given by the Convention on the International Regulations for Preventing ... -
Navigating patterns analysis for on-board guidance support in crossing collision avoidance operations
Wu, Baiheng; Li, Guoyuan; Zhao, Luman; Aandahl, Hans-Ingar Johansen; Hildre, Hans Petter; Zhang, Houxiang (Peer reviewed; Journal article, 2021) -
Path Planning of UnmannedUnderwater Vehicle (UUV ) forShortrange Fishnet Inspection Usingthe Hybrid A* Algorithm
Malisz, Michal Edward (Master thesis, 2021)This thesis present a small protion of the large motion planning domain. It focuses on the use of the Hybrid A* algorithm to generate a transverable path form A to B for underwater vehicles. The benefits is that the algorithm ... -
Toward an online decision support system to improve collision risk assessment at sea
Zhao, Luman; Sunikumar, Sai Rana Thattavelil; Wu, Baiheng; Li, Guoyuan; Zhang, Houxiang (Journal article; Peer reviewed, 2022)
