Engine type: S.E.M.T. Pielstick PC 2-5

Intervention type: maintenance

Detection: water

Reference 1: “Some time ago, during the maintenance work of a PC2-5, MFM started an alarm: thanks to it we detected that water was falling into the lube oil sump because of a leakage in way of an exhaust valve seat. If we had not known about it, the consequences would have been very serious for the engine and also costly because we would have had to change all the engine lube oil. Since then, I use MFM for all my projects:  it is a real advantage to guarantee the quality of our work and point it out to our customers.”Frédéric Albessart, Field Service Engineer, MAN PrimeServ

Reference 2: “We took the opportunity of maintenance works on 16PC2-5 emergency engines to install a MFM. We had two objectives in mind: prevent possible damage occurrences and show to our customer how useful this tool is. The facts proves very quickly how right we were: as soon as it was started MFM detected at the end of the running-in phase an increase of the water contents in the lube oil. The cost of this incident was very low compared to the serious damage we then prevented. Proposal for an MFM will be made for the preparation of the second maintenance.” Emma Lechat, Project Manager, MAN PrimeServ

Engine type: MAN 48/60B

Intervention type: major overhaul

Detection: water

Reference: “During an overhaul, our 48/60B engine being in running-in phase for about 5 hours and as all the operating parameters were good, MAN Fluid Monitor detected a sudden increase of the water content in the lube oil. We stopped the engine immediately to carry out an internal inspection – a cylinder head was leaking. Without MFM, the water ingress would have been detected too late to prevent the renewal of all the engine lube oil (approx. 20 m3).” Jean-Saül Séry, Field Service Engineer, MAN PrimeServ

Engine type: MAN 32/44 CR

Intervention type: commissioning

Detection: water

Reference: “After some damage occurred – engine flooded at the end of the commissioning phase – I used a MAN Fluid Monitor to restart the engine after draining, flushing and changing the lube oil. This proved that our work had been efficient, i.e. a real saving in terms of time and troubleshooting! The customer, who had received the MFM just before the damage occurred, was reassured about his choice, sped up its fixed installation and decided to equip each of his four 32/44 CR (GenSet) engines as well in order to monitor them for correct functioning in the long term.” Dylan Lefeuvre, Field Service Engineer, MAN PrimeServ

Engine type: MAN 51/60G

Intervention type: testbed

Detection: ferrous particles

Reference: “At the test bench, during the tests of a 51/60G new engine, the MFM started an alarm: detection of ferrous particles. It was decided to inspect the cylinders: the boroscopic inspection of the first cylinder liner detected severe scuffing. Fortunately, thanks to this early detection, only one liner was damaged. Without this detection the tests would not have stopped; resulting in possible seizing of this cylinder, and maybe a crankcase explosion. The tests were resumed with different liner/piston ring/piston configurations to find out the cause, always under MFM monitoring, which has now become systematic” Mickael Limousin, Test Engineer, MAN PrimeServ
