摘要

The device has a balloon (1) provided with two pipes (2) for continuous flowing of a product necessary to intervention. The balloon is remotely controlled and maintained in association with ground by cables (4), which are wound and unwound by winches (5) bonded to the ground. The balloon is provided with an envelope to resist high temperature in an intervention zone. A rigid part maintained by the balloon is connected to a flexible part by sealing articulation. The flexible part is connected to a provisioning source of the product for the intervention.
