Abstract

A device includes an upstream section defining a water introduction inlet; an injector for injecting a process fluid into the water introduced into the upstream section; an intermediate section mounted downstream of the injector for receiving the water containing the process fluid; a downstream section for conveying water to the fluid transport pipe being laid. The device also includes a liquid volume compensation reservoir, having a variable receiving volume of water discharged from the fluid transport pipe, a connector to which are connected the intermediate section, the downstream section and the liquid volume compensation reservoir, wherein the inlet cross-section of the compensation reservoir is greater than 40 times the internal cross-section of the intermediate section taken at the connector. This device operates reliably even when the stretch of water is rough.
