Abstract
Predictive maintenance of ocean turbines requires on-going machine condition monitoring (MCM). As part of a reactive system, each piece and type of equipment exhibits both cyclic and transient behaviors, some of which may indicate faults that presage failures. This paper identifies a number of factors that impact reliability and safety of oceanbourne turbines. Fouling, salinity, and inaccessibility of equipment are but a few such factors that set this MSM problem apart from those encountered by wind turbines, hydroelectric plants, or ship hulls and propellers
