MARVS Safety Margin (IGC 8.2)

Maximum Allowable Relief Valve Setting check - tank operating pressure must not exceed MARVS.

IGC
Margin below MARVS
0.13bar
Status
Healthy margin 0.13 bar
Formula, assumptions, and limits

IGC Ch.8 requires MARVS respected under all expected operations. Running close to MARVS → relief valve vent → cargo loss + environmental risk. BOG compressors + reliquefaction + main-engine gas consumption work to keep margin.
