Abstract
A system and methods for barrier testing of a X-mas tree production system. The X-mas tree comprises a fluid line between a set of two barrier valves, one of the barrier valves of the set of two barrier valves being an upstream barrier valve closer to a reservoir and the other barrier valve being a downstream barrier valve closer to an environment. The system provides fluid at different test pressures to the fluid line between the downstream barrier valve and the upstream barrier valve. The system comprises a first fluid connection line from a fluid source to a pressure increasing unit; a second fluid connection line from the pressure increasing unit to a first connection point on the fluid; and a third fluid connection line from a fluid receiving unit to a second connection point on the second fluid connection line.
