  • Requesting guidance on marine engine fuel consumption

    I'm trying to formulate an estimate of the amount of MGO utilized by a vessel traveling a set distance and speed, and am looking for some guidance from engineers on this issue. (I'm not an engineer.)

    Here are the parameters:

    Vessel: CMA CGM Melisande
    Engine: 12K98MC
    Travel distance = 1 mile West
    Constant speed = 10 knots
    Water is brackish
    76 degrees Fahrenheit water temperature
    72 degrees Fahrenheit air temperature
    SE wind 5mph or less
    DWT = 101387
    GT = 91498
    NT = 55432
    Carrying 60% of maximum cargo load: 33259 NT

    Engine specs:

    Could only find this engine manual - similar to 12K98MC?

    Comparative data on pg 6 of this white paper:
    https://marine.man-es.com/docs/libra...sn=4f635aa2_20

    Is there a general formula to use to provide an estimate of fuel consumption?

    I've seen this referenced online - is it accurate?
    kW power rating of the engine multiplied by specific fuel consumption in kg/kW.Hr = kg/Hr of fuel used

    Thanks for any info you can provide.
