As the size of modern LNG Gas Carriers evolve beyond the 125,000 m3 capacity, current methods of cargo tank safety valve capacity determination become less verifiable. The present procedures may be inadequate which may put the overpressure protection of the cargo tanks in danger. Present Classification Society rules require additional measures to ensure the Safety Valves protecting the tanks have proper capacity for the worst case accident scenario.

Current generation tank capacities, such as those found on the four tank cargo system carriers, presently cause the most concern for the manufacturer. The valve sizes required for these tanks are extending beyond the capability to accurately verify valve performance and capacity. Analytical determination of specification compliance is rapidly replacing actual valve testing to verify compliance.
