Preliminary study of long endurance moorless non-drifting buoy

Abstract

In this paper we propose a novel buoy concept. In order to maintain its station without the use of anchoring hardware, the buoy autonomously patrols a position. In emergency condition such as typhoon, the buoy submerges to a depth for its safety. We examined the possibility of integrating the patrol performance and the depth control abilities. A preliminary analysis on the hybridization process is performed.
