Filthy, cheap, sulphur laden fuel will be the answer and no boiler can deal with that and not make copious smoke.
She's most unlikely to be using the gas turbines at that speed - and if she were we'd not see their plume as it would be smothered by all that filth from the heavy fuel oil.
Not exactly stealth, is it?
