Trial of monitoring service for auxiliary marine machinery
17/06/2020
Mitsui O.S.K. Lines Ltd (MOL) has announced that it will launch a trial of a new monitoring service for auxiliary marine machinery, jointly developed with Asahi Kasei Engineering Corporation.The service is based on the V-MO, a vessel vibration visualisation monitor that measures vibrations in auxiliary machinery on board a vessel (such as pumps that assist the main engine) and monitors its condition. This leads to earlier detection of potential failure resulting from abnormal vibration.
In a joint research project with Asahi Kasei Engineering on the use of vibration sensors to detect abnormalities in rotary machinery, which started in November 2017, 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. Thus, MOL is determined to start a trial service with an eye towards practical application.
MOL will also conduct trial services on ten other types of vessel (targeting about 80 pieces of auxiliary marine machinery) in addition to the above 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 Fleet Optimal Control Unified System (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.
MOL positions this project as part of the Ishin Next – MOL Smart Ship project and the knowledge and expertise gained through the development of this technology will be fed back to various types of ship. The project also reflects MOL’s proactive stance in the development of vessel-related Internet of Things (IoT) and safe operation technologies.
