Heavy-transport submergence and ballast-control system
중량물운반선 잠수·밸러스트 제어 시스템
The precise ballast control of a semi-submersible heavy-lift ship, which deliberately sinks its deck below the waterline to float a cargo such as a rig on top, then rises again — an operation demanding exact control.

- Family reference-profile markers
- ● 1 Standard · ○ 0 Common · △ 0 Variant · 20 unmarked

- 5 released source-BOM records
- 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.
High-capacity ballast pumps
High-capacity ballast 펌프Very large ballast pumps that flood and empty the tanks fast enough to submerge and raise the deck in useful time.
