ClassNK’s CMAXS e-GICSX system uses a sophisticated algorithm to analyse correlations between multiple sensing data

Leading Japanese classification society, ClassNK, has started verification tests of its next-generation condition-based engine monitoring system, the CMAXS e-GICSX, onboard a Mitsui O.S.K. Line (MOL) vessel.

The condition-based monitoring (CBM) system CMAXS e-GICSX has been specially developed for Mitsui’s MAN B&W engines. It is being jointly developed by ClassNK, Mitsui Engineering & Shipbuilding Co Ltd, and MES Technoservice Co Ltd.

Apparently, the ClassNK CMAXS e-GICSX is unlike any other CBM system that has been developed to date. The system can detect machinery abnormalities and, based on abnormality detection results, provide troubleshooting that can be accessed onboard, even without an internet connection.

Machinery abnormalities are picked up by voyage data, including weather and sea condition, and machinery data collected from multiple sensors installed on the engine.

ClassNK CMAXS e-GICSX uses a sophisticated algorithm to analyse correlations between multiple sensing data. Through the use of this algorithm, precise abnormality detection is carried out based on the large amounts of data collected from the electronically controlled diesel engines.

A total of three vessels from shipping companies including MOL Group have been installed with ClassNK CMAXS e-GICSX with the aim of verifying the effectiveness of abnormality detection and making sure that the troubleshooting function can be verified. The verification test will go on until spring 2016.

Following the verification test, ClassNK will provide a system to increase the reliability of machinery and support a reduction in lifecycle costs.

ClassNK will also work together with machinery manufacturers to carry out a streamlined verification of the application of ClassNK CMAXS through vessel engine inspections.
