Containment integrity monitoring (IBS/IS N2, cofferdam heating)
격납 무결성 감시
Systems that watch the health of the tank containment itself: nitrogen pressure in the insulation spaces reveals leaks, and heating of surrounding cofferdams protects the ship's steel from the extreme cargo cold.

- Family reference-profile markers
- ● 1 Standard · ○ 0 Common · △ 1 Variant · 19 unmarked
- Component coverage
- 4 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.
IBS / IS N2 pressure control stations
IBS/IS 질소 압력제어Valve stations holding the membrane insulation spaces at set nitrogen pressures — the pressures whose behaviour reveals a leaking barrier.

질소 유량·압력 감시Instruments watching nitrogen consumption and pressure in the insulation spaces; a rising make-up flow is the classic first sign of a leak.
