Mono-atmospheric chamber

Access apparatus between a first and second chamber (1, 2) located at greater water depths, which chambers have equal pressure, lower than the water pressure, particularly an access apparatus (4) between an underwater vessel (1) and a chamber (2) at an installation on the seabed. The invention is characterized in that it comprises first and second concentric tubular elements (7, 5) designed for engagement as a telescopic cylinder, a hydraulic system for controlled actuation of the telescopic cylinder and at least on the free end of the first tubular element (7), a spherical mounted mating flange (12).

Apparatus for carrying out operations under water

A device for carrying out works under water includes a twin hull submarine (1,2) which can be combined with a number of specially adapted cargo modules (12), in which the twin hull submarine between its two hulls (1,2) is provided with a cargo holder (15) for carrying cargo modules in the compartment between the two hulls (1,2). This provides a modularized system for subsea operations, whereby a twin hull submarine, in combination with a number of specially adapted cargo modules, forms a device for carrying out various tasks under water.
