FIELD: methods or apparatus for filling pressure vessels.
SUBSTANCE: tanks are filled subsequently one after the other. In the first stage, the liquefied gas displaces the vapor under pressure from the tanks. The vapor enters the first and second auxiliary storage tanks. Vapor is released, at least, from one of the tank and enters a means for vapor utilization, such as a device for liquefying, vapor liquefying or engine or turbine for the use of the vapor as a fuel. The fluid flow into the first and second tanks is controlled to guarantee the total flow rate of vapor entering the means of vapor utilization to be constant.
EFFECT: enhanced reliability.
