Hydrogen cargo boil-off and vacuum-insulation monitoring system
수소화물 BOG·진공단열 감시 시스템
The specialised monitoring for liquid hydrogen at -253 °C: it watches the vacuum in the double-walled tank insulation and manages the unavoidable boil-off of the coldest cargo carried at sea.

- Family reference-profile markers
- ● 0 Standard · ○ 0 Common · △ 1 Variant · 20 unmarked
- Component coverage
- 6 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.
Insulation-vacuum pressure sensors
단열진공 압력센서Sensors watching the vacuum between the tank's double walls — losing the vacuum means losing most of the insulation.
Reference pattern · Per tank / circuitView Component record →COMP-123 · Instrument / SensorInsulation-space temperature sensors
단열공간 온도센서Temperature sensors in the insulation spaces revealing cold spots that betray a developing leak or insulation fault.

수소가스 검지기Detectors tuned to hydrogen around the cargo installation — the smallest molecule escapes where nothing else would.

진공유지 펌프·접속부The vacuum pump or connection used to restore the insulation vacuum when it slowly degrades in service.
Design dependent · As requiredView Component record →COMP-127 · Panel / ElectronicsHydrogen cargo monitoring panel
수소 화물 감시반The panel gathering vacuum, temperature, gas and boil-off readings into one picture of the hydrogen cargo's condition.
