Offshore crane (AHC)
해양 크레인(AHC)
A crane with active heave compensation (AHC): it senses the ship's motion and pays cable in and out automatically, so the load hangs still relative to the seabed even as the ship rides the swell.

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.
