    It's just how do you treat your fuel, from bunker tank to engine. High Viscosity bit is to tell you it is heavy fuel they are interested (>120cst or so).
    Trust me I'm a Chief.

    Views expressed by me are mine and mine alone.
    Yes I work for the big blue canoe company.
    No I do not report things from here to them as they are quite able to come and read this stuff for themselves.

      How do you transfer it from the storage (bunker) tanks to the settling tanks, what do you have to do before you can transfer it.

      What is the purpose of the settling tank?

      How does it get from the settling tanks to daily service tanks?

      What happens between the service tank and the main engine, what property of the fuel do you have to control to get proper atomisation at the injectors, what else happens between the service tank and the engine to ensure that the fuel quality is correct?
      Go out, do stuff
