A Review of Prognostics and Health Monitoring Techniques for Autonomous Ocean Systems

Abstract

Prognostics and health monitoring (PHM) is an important and growing focus in the design and maintenance of complex systems. It is being applied to a wide range of problems, from industrial machines to avionics systems to batteries. In this paper, we review existing work in the context of a novel application: repair and maintenance of autonomous ocean systems, one example being a fleet of ocean turbines. Various approaches to PHM are considered, including model- and data-driven techniques as well as hybrid strategies.
