24th Oct 2007Dr. Vis,
Need your advice. Vessel bunkered 200 tons grade RMG380 low sulphur fuel oil at St Petersburg, Russia. Several days into sea voyage, main engine rpm dropped (without knocking sound) and engine was stopped. All six units main engine fuel oil pumps sustained damage (scoring on barrels and plunger, seizure). Aux engine fuel pumps also sustained damage. Subsequently, Chief Engineer rectified and proceeded with other fuel oil onboard. Bunkered fuel oil samples (two) had been sent to DNVPS for analysis and tested parameters (per ISO8217) stated fuel oil complies to ISO8217:2005 RMG380 specification; particularly AL + SI (catfins 7) and sulphur (1.31). C/E reported fuel oil purification system, main engine exhaust temperatures, fuel oil temperature to engine, turbocharger, etc were satisfactory. Can you plse advise what could hve caused the fuel oil pump damage on the M/E and Aux engine.

IP: x.x.171.34PanAm Generating is a power plant located in Panama running with six 18W46 engines.
Since the past July we started having similar problems with our injection pumps and the capacity of our generating units was reduced in 20%. We have checked all the scavening related systems and fuel treatment, and we did not find anything wrong.
We have knowlege that at least four similar power plants in Central America area dealing with the same problem and all of them have requested help to DNV. We have requested also for help to DNV.
We will be able sharing any related information.

The problems you are talking about can and has been eliminated just by using an lubrication improving fuel oil additive. It is very common that the LSFO create such problems.
The additive can be injected into the fuel line 1 liter additive / 1 MT fuel. The additive has several other performance improvements to offer as well.
The cost for using the additive is nothing in comparison to the cost to overcoming your problems. For more information contact me at additive@otenet.gr - Masoud Zakian
