Device for controlling the filling of a pipe as it is being laid in a stretch of water, and associated assembly and method
First Claim
1. A device configured for controlling the filling of a fluid transport pipe being laid in a stretch of water, comprising:
- An upstream section defining a water introduction inlet;
A process fluid injector configured for injecting a process fluid into the water introduced into the upstream section;
An intermediate section mounted downstream of the process fluid injector configured for receiving the water containing process fluid;
A downstream section configured for conveying water to the fluid transport pipe being laid in the stretch of water;
A liquid volume compensation reservoir, having a variable receiving volume of water discharged from the fluid transport pipe,A connector to which the intermediate section, the downstream section and the liquid volume compensation reservoir are connected, an inlet cross-section of the liquid volume compensation reservoir being greater than 40 times an internal cross-section of the intermediate section, taken at the connector.

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.
