Fuel changeover system
연료 전환 장치
Valves and controls that switch the engines between fuels — for example heavy fuel to low-sulphur gas oil before an emission control area — gradually, so thermal shock does not damage the injection equipment.

- Family markers describe reference applicability. Component links are released source-BOM listings and do not assert complete engineering containment.
FAMILY REFERENCE APPLICABILITY
Family profiles carrying a source marker.
Unmarked Families are not listed; an unmarked cell means “not normally fitted” in the source Family profile, not confirmed absence from a vessel.
