Bad bunker fuel is a recurring problem and Houston appears to be the source again:
Is it residue from fracking fluid or are somebody getting rid of troublesome waste the cheap way?
Bunker contamination may be more widespread than commonly known:
In a repeat of the last fuel contamination case,this one has now spread to Singapore:
Bunker metering systems – how do they work and why are they needed?:
I assume the fuel is run thru the centrifuge before it hits the day tank so it must be some serious contamination? maybe it isn’t being run thru the centrifuge??
Is it solids or liquid chemicals?
as usual, for a engineer the article is about as informative as talking to a dinner fork!!
Fuels that comply with routine ISO 8217 testing can still generate operational problems on board, the LR’s Fuel Quality Report revealed.
"Manipulation against the flow
Despite the broadening appeal, and the tamper‑resistant design work that has gone into MFM solutions, there have been instances that show they can still be manipulated through physical or operational interference.
The most well‑known example concerns the bunker tankers Southernpec 6 and Southernpec 7 in Singapore. Between 2016 and 2019, industrial‑strength magnets were placed on the MFM sensors to distort measurement signals, causing the meters to record more fuel than was actually delivered. The fraud resulted in buyers being cheated of over US$300,000 worth of marine fuel oil.
