An expert system towards solving ship auxiliary machinery troubleshooting: SHIPAMT_SOLVER

This study proposes an expert system to aid shipboard personnel for solving ship auxiliary machinery troubleshootings. The developed expert system, called as SHIPAMT_SOLVER, is structured based on PROLOG programming language. Principally, the SHIPAMT_SOLVER suggests an optimum action code for the shipboard personnel with respect to the established rules on technical knowledge, system indicators, and previous failure experiences from the auxiliary machinery systems. As an illustrative case application, the SHIPAMT_SOLVER is performed over a probable failure scenario in a ship refrigeration system. Utilization of the SHIPAMT_SOLVER on board merchant ships ensures an effective decision aid on corrective actions while reducing the response time to failures especially in manoeuvring positions and voyages in critical waters.
