The device comprises: - an upstream portion (34) defining an inlet (48) for introducing water; - injection equipment (36) for injecting a treatment fluid into the water introduced into the upstream portion (34), - an intermediate portion (38) mounted downstream of the injection equipment (36) to receive the water containing the treatment fluid; - a downstream portion (40) for conveying water toward the fluid transporting pipe (12) in the process of laying. It comprises: - a reservoir compensating for the volume of liquid (42), having a variable volume (44) for receiving water displaced from the fluid transport pipe (12), - a coupling (46) to which the intermediate portion (38), the downstream portion (40) and the liquid volume compensation reservoir (42) are connected, the inlet cross section (S3) of the liquid volume compensation reservoir (42), considered at the level of the coupling (46), being greater than 40 times the internal cross section (S1) of the intermediate portion (38), considered at the level of the coupling (46). This device operates reliably even when the stretch of water is disturbed. |
