Abstract
A fuel feeding system for storing liquefied gas and feeding gaseous fuel to be used in a piston engine, which fuel feeding system includes at least two cryogenic fuel tank arrangements having a first tank arrangement and a second tank arrangement in connection with each other. The fuel feeding system includes a gaseous fuel feed line connected at its first end to at least one piston engine, in which system the first tank arrangement is provided with a pressure build-up system having a first heat exchanger unit. The inlet of the heat exchanger unit is connected to a bottom section of the first tank arrangement the outlet of which is connectable to the top section of the first tank arrangement. The first tank arrangement and the second tank arrangement are both pressure vessels, and the first tank arrangement is selectively connectable to the fuel feed line by a gas line extending from an outlet in the top section of the first tank arrangement.
