ABSTRACT
As vessel move from the water point to water point and other water environments, safety of safety controls interacting with vessel becomes a key issue [1, 2]. The vessel system must provide a mechanism to ensure ship safety, given the uncertain environment and untrained sailors. To ensure the safety and intuitiveness of the interaction, the complete system must incorporate (i) safe mechanical design, (ii) safety control friendly interfaces such as natural language interaction and (iii) safe planning and control strategies. Our work focuses on this third item. In particular, the goal is to develop strategies to ensure that unsafe sailing does not occur between any point on an articulated vessel and a safety control in the vessel’s workspace. This paper focuses specifically on the real time safety during safety control of vessel interaction. The concept of e-navigation can be drawn as below figure 1. The process of enavigation will affect whole process of development. The process of practice and operation is affected by user requirement, operational function, and technical equipment and gear.
