Turret / spread-mooring and swivel-transfer system
터릿·스프레드 계류 및 스위블 이송 시스템
The permanent mooring of a floating production unit: either a turret the ship weathervanes around — with a swivel passing oil, gas and power across the rotation — or a spread of anchor lines holding a fixed heading.

- Relationship meaning
- 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.
RELEASED SOURCE-BOM LISTING
Released Component records.
Coverage is partial and Family-independent: selecting a Family does not alter the Component records linked to this System.
Turret structure and bearing
터릿 구조물·베어링The structure and large bearing about which the whole vessel weathervanes while staying moored.
