Title
(EN) MARINE BARRIER SYSTEM FOR HARBOUR PROTECTION
(FR) SYSTÈME DE BARRIÈRE MARINE POUR LA PROTECTION PORTUAIRE
Abstract
(EN) A marine barrier system (10) is provided, comprising a partition (12) configured for being submerged within a body of water to serve as a barrier, the partition comprising a passage section (14), a top portion of the passage section being moveable between a raised barrier position wherein the top portion is at or near a surface of the water, and a lowered passage position wherein the top portion is submerged within the water to a sufficient depth to allow passage therethrough of a marine vessel. The barrier system further comprises a passage opening system (16) having a partition- carrying portion, the passage opening system being configured to maintain the top portion of the passage section in its raised barrier position when the partition- carrying portion is buoyant with respect to the water, and to maintain the top portion in its lowered position when the partition- carrying portion has an overall density greater than that of the water.
(FR) L'invention porte sur un système de barrière marine (10) qui comprend une séparation (12) configurée pour être submergée à l'intérieur d'un corps d'eau afin de servir de barrière, la séparation comprenant une section de passage (14), une partie supérieure de la section de passage étant mobile entre une position de barrière élevée dans laquelle la partie supérieure se trouve au niveau d'une surface de l'eau ou au voisinage de celle-ci, et une position de passage abaissée dans laquelle la partie supérieure est submergée à l'intérieur de l'eau à une profondeur suffisante pour permettre le passage à travers celle-ci d'un vaisseau marin. Le système de barrière comprend de plus un système d'ouverture de passage (16) comportant une partie de support de séparation, le système d'ouverture de passage étant configuré de façon à maintenir la partie supérieure de la section de passage dans sa position de barrière élevée lorsque la partie de support de séparation est flottante par rapport à l'eau, et à maintenir la partie supérieure dans sa position abaissée lorsque la partie de support de séparation a une densité globale supérieure à celle de l'eau.
