Human Factors and Ergonomics in Manufacturing &Service Industries, Volume 33, Issue 5, Page 395-429, September 2023., 2023 Abstract Maritime Autonomous Surface Ships (MASS) currently have no formal regulations developed specifically for their operation, as their regulatory framework is still under development. Rasmussen's Risk Management Framework has been used to develop an actor map of the current MASS system in the UK, to show who the actors, decision‐makers, and ...

COLREGs-Informed RRT* for Collision Avoidance of Marine Crafts [PDF]
2021 IEEE International Conference on Robotics and Automation (ICRA), 2021 The paper proposes novel sampling strategies to compute the optimal path alteration of a surface vessel sailing in close quarters. Such strategy directly encodes the rules for safe navigation at sea, by exploiting the concept of minimal ship domain to determine the compliant region where the path deviation is to be generated.

Journal of Advanced Transportation, Volume 2022, Issue 1, 2022., 2022 A novel real‐time collision avoidance method for autonomous ships based on modified velocity obstacle (VO) algorithm and grey cloud model is proposed. A typical VO algorithm is used to judge whether there is a collision risk for ships in the potential collision area (PCA).

VORRT-COLREGs: A Hybrid Velocity Obstacles and RRT Based COLREGs-Compliant Path Planner for Autonomous Surface Vessels [PDF]
OCEANS 2021: San Diego – Porto, 2021 This paper presents VORRT-COLREGs, a hybrid technique that combines velocity obstacles (VO) and rapidly-exploring random trees (RRT) to generate safe trajectories for autonomous surface vessels (ASVs) while following nautical rules of the road. RRT generates a set of way points and the velocity obstacles method ensures safe travel between way points ...
