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.

Circulation pump units
순환펌프 유닛Pumps circulating oil through the stern tube bearings, keeping them lubricated and cooled where the shaft leaves the hull.
Needs evidence · Design dependent — pump quantity and capacity split not yet evidencedView Component record →COMP-433 · Tank / VesselForward / aft gravity tanks
전후부 중력탱크Header tanks whose height sets the oil pressure at the seals, deliberately kept above sea pressure so oil leaks outward rather than water inward.

후부 실 공기 제어 유닛The air-pressure control for modern air-type aft seals, which use an air barrier to keep oil out of the sea.
