LNG boil-off is used as fuel in the dual fuel system to produce steam in the boilers to run the turbines. What happens nder slow maneuvering speeds, due to excessive steam being generated?

Correct Answer: Option C — the steam produced in the boiler, due to the dual fuel system, is dumped to the main condenser

During slow maneuvering, excess steam generated in marine boilers from dual-fuel boil-off is safely bypassed and dumped directly into the main condenser to condense the steam back into feedwater, preventing over-pressurization of the boiler.
