Preventive maintenance of marine engines, is maintenance based on the number of operational hours. When preventive maintenance takes place the engine is inspected, spare parts are replaced and oil is changed. All is done preventively, to prevent worn out parts or contaminated oil from causing damages and engine failure.

However, in most cases maintenance isn’t necessary. On top of this, ship down-time and the costs of spare parts are highly cost intensive.

Insight into the actual status of the engine

In the ideal situation, maintenance will only be carried out when necessary. To be able to do this, it is of essential importance to have insight into the actual status of the engine and its parts. Until recently is wasn’t possible to get insight into piston engines (reciprocal machinery) at such a detailed level. There are condition monitoring systems available on the market that measure output indicators like pressure, temperature and gas. The moment these indicators change, the user knows something is breaking down inside the engine.
The disadvantages of this type of cbm systems are: 1) it isn’t clear where the disruption is located. This needs to be investigated first. 2) When the output-indicators change, this means something already is significantly wrong inside the engine. Therefore in most cases it is too late to take action.

REDS Maritime: from preventive to condition based maintenance

As said ‘until recently it wasn’t possible to gain insight into the actual status of the engine’. We developed a revolutionary engine monitoring system that changes maintenance management for good. REDS Maritime detects even the smallest deviation within the engine, weeks or months before they are detectable as pressure, heat or gas. With REDS Maritime preventive maintenance of the marine engine belongs to the past. Condition based maintenance is the new standard.

Predict engine failures weeks or months before they occur

REDS Maritime is an engine monitoring system that 24/7 measures the torsional vibrations within the engine, by placing two sensors on the flywheel of the crankshaft. Based on the measurement information the balance of the engine is determined and monitored. Because REDS Maritime measures so precisely, even the smallest deviations in engine balance are detected. Weeks or months before these deviations are detectable as pressure, heat or gas emission.
Another advantage of REDS Maritime is that it indicates where the deviation is located within the engine and what might be the cause. Because the system signalizes a deviation at such an early stage, the user has enough time to pick the most suitable place and time to carry out maintenance.

Deviations are nipped in the bud and the engine can be brought back back into its optimal efficiency mode. With REDS Maritime maintenance only has to take place when an abnormality has been detected. Therefore costly preventive maintenance activities belong to the past.
