3. Callosum MT: Service and maintenance with EHM functionality mtu
designed and developed its Callosum MT maintenance and service system specifically for long-term, high seas missions. With its new functions, Callosum MT serves as a high-performance Equipment Health Monitoring System capable of playing a significant role in increasing vessel availability, enhancing reliable operational planning and cutting maintenance and materials costs in order to meet the demands that modern maritime defence forces will face in the future.
Callosum MT bundles all available data on the propulsion and on-board electric power generation systems, employs sophisticated techniques to analyse that data and then makes the results accessible for the crew on all of the displays in the automation system network. Data can also be stored and transmitted for further analysis at a later point.
Callosum MT is based on three mutually complementary modules covering three different maintenance aspects. Corrective Maintenance covers support in concrete fault events whilst Preventive Maintenance covers servicing on the basis of a digitised maintenance schedule. To some extent, the Condition-Based Maintenance module can be seen as the master element as it facilitates supervision of the vessel on the basis of the actual condition of the equipment fitted. The system utilizes the latest analysis techniques to evaluate sensor data and make results available.
3.1 Corrective Maintenance
With the introduction of the Corrective Maintenance module, mtu
set new benchmarks for automation systems. When Callosum MT’s electronic diagnostics program detects irregularities, signs of wear or functional defects, the system does more than simply report them automatically to the vessel’s crew. The report also includes information on the source of the fault. Once the crew has located that source, the system automatically guides it through the appropriate repair process: The components and tools needed (including ID numbers) for repairs are displayed. 3D videos provide precise instructions to staff on how to perform the individual step (Figure 4).
