Problems solved by technology
Such empty space is not always available, which complicates finding a suitable mounting site for the equipment and thus makes installation more difficult
Since the valve device of this known device is fastened with a plurality of DTB parts located on the circumferential outside of the valve device, the valve device requires a large mounting surface

Embodiment Construction
[0021] figure 1 A submerged container 5 is shown to which is attached the device 1 of the invention for recovering a liquid, such as oil, from the container 5 . The device 1 is connected by a hose 27 to a remote control 28 of a boat 29 . A power source 31 for driving the basic functions of the device 1 is located on board the ship 29 . Typically, the power source 31 sends power to the device 1 via the hose 27 . Hydraulic power and / or pneumatic power may also be included in the power source 31 .
[0022] Equipment for recovering liquids 1 in Figures 2 to 4 shown in more detail.
[0023] The device 1 comprises a frame 20 for supporting the different components of the device.
[0024] In order to prevent water from entering components that could be damaged by water, the device includes a protective enclosure 24 . This enclosure 24 also prevents liquid from escaping from the container 5 to water outside the container 5 after the through-hole 8 has been machined into the con...

The invention relates to an apparatus for recovering liquid from a submerged container (5), said apparatus comprising a tool assembly comprising a processing tool for making a through hole in the submerged container (5), and a fixing arrangement (6) for fixing a valve arrangement (7) liquid tight at the site of the hole processed to the submerged container (5). To enable easy and fast mounting of the valve arrangement (7), the apparatus comprises sealing means comprising an elastic flexible member surrounding the processing tool, transfer means for transferring the processing tool two-dimensionally in a X-Y plane for processing a hole having anon-circular shape, the fixing arrangement (6) comprises a cylindrical part (18) having one or more stop surfaces to be placed beyond the hole against the inner surface of the submerged container, the cylindrical part (18) further having one or more stoppers (12a, 2c) to be positioned against a wall portion of the hole, a threaded (22) flange part (15) being associated with the valve arrangement (7), the cylindrical part (18) being attached to the flange part (15); and an actuator for rotating the flange part (15) relative to the cylindrical part (18) to position the wall of the submerged container (5) in compression between the stop surfaces and the flange part (15).
Description
technical field [0001] The present invention relates to a device for recovering liquid from an underwater container, more particularly to a device according to the preambles of the appended independent device claims. Such equipment is often used to recover liquids such as oil from the containers of sunken ships to reduce environmental damage caused by liquids leaking from the containers into the surrounding ocean. [0002] The invention also relates to a method for recovering liquid from an underwater container, more particularly to a method according to the preambles of the appended independent method claims. Background technique [0003] Such an apparatus and method for recovering liquids is known from US Patent No. 7377226B2. A disadvantage of this known device is that it is practically difficult to attach to an underwater vessel. This is due to the fact that the fixing means used to fix the valve means of the device at the site of the bore of the submerged vessel compr...
