Japan's NYK Line has developed an innovative sound-based approach to monitoring ship machinery.

Its subsidiary Monohakobi Technology Institute has come up with a diagnostic tool, Kirari MUSE, that detects potential machinery failure by recording and comparing the sound of machinery in operation. The sound, represented in visual graphic form on a tablet, allows remote and shore-based monitoring and analysis.

Kirari MUSE offers an alternative to the mainstream approach to machinery monitoring, which is principally based on the transmission of electronic data from sensors.
