Mitsui O.S.K. Lines, Ltd. (MOL) have announced that the company will launch a trial of a new monitoring service for auxiliary marine machinery, jointly developed with Asahi Kasei Engineering Corporation.
MOL says that the service is based on the Vessel Vibration Visualization Monitor (V-MO), which measures vibrations in auxiliary machinery onboard a vessel. This includes items such as pumps that assist the main engine and monitor its condition. This leads to earlier detection of potential failure resulting from abnormal vibration.
The roots of this new trial stretch back to a joint research project started in November 2017 with Asahi Kasei Engineering on the use of vibration sensors to detect abnormalities in rotary machinery. The project team monitored different types of essential auxiliary marine machinery on two newbuilding vessels and another in-service vessel (targeting about 20 pieces of auxiliary equipment) over two years. The project showed positive effects in detecting early signs of failure that could result in an engine stoppage and in managing failure tendencies on the three vessels involved. As such, MOL determined to start trial service with an eye toward practical application.
MOL will also conduct trial services on 10 other various types of vessels (targeting about 80 pieces of auxiliary marine machinery) in addition to the three vessels, verify the comprehensiveness of the vibration diagnosis technology, and confirm vessel-specific service content based on MOL’s expertise in vessel operation, maintenance, and ICT. Once the system is in practical use, it will be linked to MOL’s FOCUS project.
MOL aims at practical use by March 2021 after the trial service is completed; at that time, Asahi Kasei Engineering will offer the service to other shipping companies and ship management companies as well as MOL.
