Description

The invention relates to a lifeboat for the crew of a ScMffes or a working platform located away from the coast, the device for carrying out diving activities having.

After diving work Ia at great depths, divers have to stay under increased pressure for up to a few days. These are located on the ship or the working platform, carried out from where or from where the work and be monitored else or more pressure chambers for ä @ n stay the diver after completion of the work.

If in an emergency the crew of the ship or the platform must go overboard, those people who are in the pressure chamber must be able to be rescued without the decompression is affected.

The task of the invention is, in the event of an emergency, to be able to rescue people who are vulnerable in a Tanefakaraiisr without interrupting the decompression. - 9Q9828 / 0858

ii O j H ι t I

This object is achieved in that the lifeboat as a buoyant vehicle has a pressure chamber for staying and / or for decompressing divers who have started or finished their diving work, and that the pressure chamber Has access openings that are gas-tight to other pressure chamber systems can be connected to the ship or the work platform.

With the lifeboat according to the invention, not only the crew can of a ship or a work platform, insofar as it works under normal atmospheric conditions people can also be rescued who are under increased pressure in the pressure chamber.

Further features of the invention emerge from the subclaims.

In the following an embodiment of the invention shown in the drawing is explainedj it shows the single figure schematically and partially in section a side view of a Lifeboat.

The lifeboat 1 shown in the figure is a closed one Lifeboat with its own propulsion system. The lifeboat can be arranged on a ship or on a work platform 2 be. Ss is. hung on davits 3 in a manner known per se or arranged so that it can be easily lowered into the water can. In the lifeboat 1 there is a pressure chamber 4 which, at one end 5, is connected to a pressure chamber housed in the lifeboat Device is connected to maintain and monitor a suitable atmosphere in the pressure chamber 4 is determined and therein the pressure, the breathing gas composition, adjusts or monitors the carbon dioxide content, the temperature and the humidity. The other IMe β of the pressure chamber 4

is connected to a gas-tight lock 7. One end of this extends through the outer skin of the lifeboat Components 10 or 13 and is connected with this end to a pressure chamber system on the ship or the work platform. This pressure chamber system has an antechamber 8 and a pressure chamber 9. The lock 7 is detachable and gas-tight with the Pressure chamber system 8, 9 connected, e.g. via a connection 10, and also has a gas-tight closure 11.

The other end 13 of the lock 7 is detachably and gas-tightly connected to a movable transport or decompression pressure chamber 12 and has a gas-tight closure 14.

The lifeboat preferably has the necessary equipment to maintain a suitable climate, a system for Generation of electrical energy, a supply of breathing gas, oxygen, carbon dioxide and moisture-absorbing material. The entire equipment is expediently housed in watertight compartments of the outer skin, so that the pressure chamber 4 also is functional when the lifeboat is partially full of water.

The pressure chamber can advantageously be connected to the lifeboat via an inner bottom and thereby together with the Form the outer skin of the lifeboat in a sandwich structure.

In order to distribute the load on the pressure chamber over a larger part of the outer skin of the lifeboat, the pressure chamber be connected to frames or side members of the lifeboat.
