ClassNK monitoring system for Makita MAN engines

ClassNK is to extend its condition-based engine monitoring system ClassNK CMAXS eGICSX to Mitsui-Makita MAN B&W main engines.

The system, under development in collaboration with Mitsui Engineering & Shipbuilding, assists in the early detection of abnormalities in electrically controlled diesel engines. The project addresses the growing need for analysis of sensor data from such engines, as the number of vessels employing electronically-controlled diesel engines rises.

ClassNK’s solution incorporates Mitsui’s e-GICS (electronic Global Internet Customer Support) technology and ClassNK’s advanced big data analysis technology to create a support system for preventative maintenance on ships. Data is automatically analysed to provide performance diagnoses, making it possible to conduct early countermeasures to prevent critical, time-consuming repairs and extend the frequency of overhaul intervals.

The system aims to ensure safe operation of the ship and reduce lifecycle costs. Project completion is scheduled for March 2016.

Makita and Mitsui signed a technology collaboration agreement in 1973 before the start of their license agreement with MAN B&W in 1981. MAN B&W diesel large bore engines are manufactured and sold by Mitsui in Japan, with small bore (under 500mm) engines manufactured by Makita.
