Ro-ro ramps & shell doors
로로 램프·현측문
The hinged ramps and hull doors through which vehicles drive on and off a ro-ro ship. Because they are openings in the hull itself, their locking and sealing is safety-critical and their status is shown on the bridge.

- 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.
