Abstract: A pipe (14) extending between a surface end (20) and a bottom end (22) thereof, and defining an internal passage (24) ending at the bottom end (22) and at the surface end (20). A dynamic closing member (30) at the bottom end (22), which opens above a threshold pressure applied from the exterior towards the interior of the pipe (14), and closing below the threshold pressure. The threshold pressure is defined as a function of at least one parameter representing the heaving of the pipe under the effect of variation in height of the water in which the pipe extends.

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.

Abstract: The disclosure includes a recovery system and method for recovering a deployed vessel having a rotatable support coupled with a stored recovery assembly, including a release unit, line, deployment weight, and drag device on the deployed vessel. A recovery vessel can have a hoist with a coupling element, such as a grapple. For recovery, the recovery assembly can be deployed from the deployed vessel. The drag device can assist in floating and/or maintaining a taut line, especially when the vessel is downwind of the drag device. The coupling element from the recovery vessel can couple with the taut line. Once coupled, the recovery vessel can raise the coupling element with the line, which can rotate the rotatable support to a lifting position above a center of gravity of the deployed vessel. The recovery vessel can then lift the deployed vessel vertically out of the water to a storage position.

Abstract translation: 本公开包括用于恢复部署的容器的恢复系统和方法，所述容器具有与存储的恢复组件相连的可旋转支撑件，所述可回收支撑件包括释放单元，管线，展开重量和拖曳装置。 回收容器可以具有带有耦合元件（例如抓斗）的起重机。 为了恢复，可以从部署的容器部署恢复组件。 牵引装置可以帮助浮动和/或保持拉紧线，特别是当容器是拖拉装置的顺风时。 来自回收容器的耦合元件可以与拉紧线耦合。 一旦联接，回收容器可以用线将联接元件升高，该线可以将可旋转支撑件旋转到在展开的容器的重心上方的提升位置。 然后，回收容器可以将部署的容器垂直地从水中提起到存储位置。
