And that's because shipping has very tight margins, and they want cheap fuel, so they use something called bunker fuel, which was described to me by someone in the tanker industry as the dregs of the refinery, or just one step up from asphalt.
A to je zato jer brodarstvo ima vrlo malene marže, i žele jeftino gorivo, tako da koriste nešto zvano gorivo iz spremišta, koje mi je opisano od nekog iz industrije tankera kao nataloženi ostaci iz rafinerije, ili samo korak od asfalta.
