– to minimize a gas amount which it is needed to pump out and recharge after maintenance of any part of equipment.

Every gas compartment must be equipped necessary valves, to provide pumping and gas refuelling without pumping from any other compartment. To reduce possibility of loss, connection pipes between gas compartments is shut out.

Every gas compartment must be equipped a static filter. These filters must be in a position to absorb any aquatic steam which can penetrate into a construction, and must be effective on an extent at least between basic conclusions in repair.
