    Default Types of cargo

    Can someone please define 'fuel' and 'patent fuel' as cargo; what's the difference and where used?

    If you are referring to tankers carrying fuel as cargo , then my knowledge only stands to jet A1 and 2 and petrol which is self explanatory. Fuel which was usually diesel was passed to oil rigs and such out of the vessels own supplies if compatable to requirements. If carrying helicopter fuel that was usually carried in special containers and passed over by crane to a helicopter landing strip. Oil tankers carry all sorts of different fuels besides crude oil which has to be refined into others.before use. From your heavy oil come all your different types going down to your paraffins and other light oils. JS

    In 1985, The U.S. E.P.A. compiled the following chart. That's just a start of the different classes of fuel ( oil ). It might help a little...

    The word patent as regards cargo had me a bit flummoxed. so taken the dictionary description of the word is...copyright , franchise, obvious, apparent, evident, clear, glaring.
    I assume the answer will come under one of those categories.
    Just out of inquisitiveness is this a quest that is a training question in some sort of pre sea school education agenda. ?

    The term "fuel" most likely refers to a bulk quantity of petrol, diesel etc, whereas "patent fuel" would refer to the same fuel after the various fuel retailers have added their own additives that supposedly would make the fuel burn cleaner or give you more m.p.g. seen it often on tankers where we would be discharging bulk petrol (or diesel) to a shore storage facility and a representative of a fuel retailer , e.g. Esso, B.P. Shell, would turn up and add litres of their additive to a full cargo tank of fuel thus making it destined for that particular company's outlets.

    One of my 2 tankers was on the Kiwi coast running from Whangerie down to Bluff and all ports in between with about 26000 tons of petrol. This was distributed into various road tankers to go to the various garages of whatever title be it shell or bp It was all, the same grade , so the additives supposedly added is new to me, one never stops learning. cheers JS.

    That may have happened then, maybe that’s why they can all charge different prices, I have always done them an injustice then as always said how can they charge different for the same product , sorry BP and Shell hope your profits didn’t suffer through my bad advertising. Cheers JS.
