Abstract

Field studies have demonstrated that the non-intrusive load monitor (NILM) can effectively evaluate the state of many electromechanical systems by analyzing the electrical power that they draw. This paper discusses NILM applications in the marine environment. Machinery power data collected from USCGC SENECA (WMEC-906), a 270-foot U.S. Coast Guard cutter, indicates that the NILM can successfully diagnose the failure of flexible couplings and the presence of leaks in cycling systems. This paper discusses both of these shipboard problems, and it details the methodology used to develop the metrics that diagnose them.
