ABSTRACT:
An installation for and a method for driving a submarine pipeline scraper, wherein one of the ends of the pipeline has a launch device and the other end has a receiving device. The scraper defines an upstream chamber and a downstream chamber. It can be launched inside the pipeline from the launch device in the direction of the receiving device, allowing water to enter through the launch device in order to subject the upstream chamber to hydrostatic pressure. The receiving device is identical to the launch device, such that water can enter through the receiving device in order to balance the pressure of the two chambers, and also enables a fluid to be injected into the downstream chamber to drive the scraper toward the launch device.
