“I personally inspected the MGO bunker tanks. The tanks were clean.”
Dear Mr. Sari,
Following our yesterday’s teleconference I would like to inform you on my observations regarding the use of “FuelRight” additive in our vessels.
Our fleet consists of three vessels. Two tanker/ro-ro vessels that operate solely on MGO and one chemical tanker that operates primarily on IFO 180 but uses MGO to enter/leave ports. We frequently had a lot of problems with bacterial infections in MGO storage tanks. At the time, we were using Bioguard to treat the MGO tanks and while it was somewhat effective, we actually had to manually clean the MGO tanks every 2,5 years (when the vessels were dry-docked) in order to remove sludge.
In May 2015 we started using FuelRight additive to all our bunker tanks both in MGO and IFO. Immediately we noticed a night and day difference in MGO tanks. There were no problems with microbial infection whatsoever. In fact we have now stopped using the onboard microbial test kits and we can almost strip the tank to its bottom without having problems with filters clogging as we had before using FuelRight. I personally inspected the MGO bunker tanks of one of our vessels that was dry-docked on September 2015. The tanks were clean.
As for the IFO 180, I carried out a lot of tests, with and without FuelRight during these eighteen months over several bunkerings as to ensure that I could attribute any positive results to FuelRight and not to the possible variations in bunker quality. I can now attest that there is less sludge production and the fuel filters’ cleaning intervals increase significantly, about 30% when using FuelRight. Bunker quality of course still remains of great importance.
The vessel has also shown significant fuel economy, about 18% in the last year, but since we have implemented some other good practices regarding fuel economy at the same time that we started using FuelRight, it is difficult to assess how much does the additive result in fuel economy by itself. Overall, ours has been a positive experience. We intend to keep using FuelRight in the future, treating our MGO and IFO bunkers on a continuous basis.
