Title
(DE) UNTERWASSER- ENERGIE- UND DATENÜBERTRAGUNGSEINRICHTUNG
(EN) UNDERWATER POWER AND DATA RELAY
(FR) RELAIS SUBAQUATIQUE D'ALIMENTATION ET DE DONNEES
Abstract
(EN)
An underwater apparatus for performing subsurface operations adapted to be operated from a remote location (50) above the surface of a body of water (8) is disclosed. The apparatus includes a linelatch system (10) that is made up of a tether management system (12) connected to a flying latch vehicle (20) by a tether (40). The tether management system controls the amount of free tether between itself and the flying latch vehicle. The flying latch vehicle interfaces with various underwater structures (60, 70). Also disclosed are methods of transferring power and/or data between two or more underwater devices using the linelatch system of the invention.

(FR)
L'invention concerne un dispositif subaquatique, pour opérations subaquatiques, exploité depuis un emplacement distant (50) au-dessus de la surface de l'eau (8). Le dispositif comprend un mécanisme d'attache de ligne (10) constitué d'un système de gestion de câble d'attache (12) relié à un véhicule d'attache mobile (20) par un câble d'attache (40). Ce système de gestion contrôle la quantité de câble libre qui le sépare du véhicule, lequel assure l'interface avec différentes structures subaquatiques (60, 70). L'invention concerne également des procédés de transfert d'énergie et/ou de données entre deux ou plus de deux dispositifs subaquatiques, qui reposent sur l'utilisation du mécanisme d'attache de ligne considéré.
