The means mentioned include, for example, a system with additional propellers and an automatic control device assigned to them, by means of which the additional propellers can be controlled in such a way that the ship is held in the desired position. It should be noted that it too
It is possible to use propellers of a special type which not only serve to propel the ship, but which can also be used to automatically hold the ship in the desired position.Furthermore, one can use action motors of the jet type instead of * propellers to hold the ship in the desired position.

in which oil or gas coming from the rock forinations under the Bottom of the water is obtained, is collected. These containers can be located under the bottom of the water, above the bottom of the water, but below the water surface or above the water level be provided. According to Pig. 1 the line 4 is connected e.g. by a line 7 to a separator 5, the. on a frame b made of steel or concrete is arranged, the Scaffolding stands on the bottom 2 of the water. It should be noted that the containers can also be carried on or on other floating non-

The extracted oil or gas is used Separator b is supplied via a line ö. The free end of the Line 4, which is preferably flexible, is at least connected to a float or at least one buoy.

If necessary, it is possible to arrange one or more such additional screws on the ship in such a way that it is possible to remove the or each reed screw from the water, so that the resistance of the ship is not unnecessarily increased during normal operation.

3,211,121 was swept. It should be noted, however, that the invention is not limited to these known automatic means and that other suitable means can also be used could use known means of maintaining the ship's position.

Y / enn of the aforementioned devices to the automatic Maintaining the position of a tanker without using anchors requires a relatively large one Drive power for the additional propellers. Depending on the wind and current conditions, this power requirement can be a significant part of the normal driving operation of the Ship's required performance *

The method according to the invention takes place in the manner described below. Assume that a tanker e.g. to be charged with natural gas. The tanker 15 approaches the buoy 10. As soon as the tanker approaches the buoy has approached, it will almost or completely come to a standstill brought the system to automatic maintenance the position of the tanker without using anchors. The amount of deviation of the tanker from the desired position is used with this system a tensioned rope, so-called reply transmitters or the like determined. Then the free end of the line 4 with Using the harness or winch 18 on board the tank sniff brought, and the line 4 is to the ^ charge line 17 of the Tankers connected. The valves 12 and 14 are now opened. The valve 14 can be opened, for example, by in the line 4 a pressure pulse is generated. The natural gas flows

now via line 4 to the tanks of the tanker, in which the gas is stored under high pressure, for example. When the loading process is complete, the valves 12 and 14 are closed and the end of the line 4 is separated from the loading line 17, whereupon the end of the line 4 is hung again on or under the buoy; this approach is carried out with the aid of the lifting gear 18. The system for automatically maintaining the position of the tank cutter without using anchors and the additional propellers 16 are then put out of operation, whereupon the normal propulsion screw is activated iceit is set so that the tank sniff has its j? ^can arrive at the destination. Instead of putting all additional propellers out of operation, it may be possible to use the additional propellers to propel the ship during the voyage, provided that these propellers are set up accordingly. It is obvious that extinguishing will work of the tanker 15 is played in substantially the same manner as was described above with regard to loading.

Instead of natural gas, it is of course also possible to load or unload other U-ases; This applies, for example ^methane: propane, ethane, ethylene, butane and oxygen. Instead of gases in the gaseous state, liquefied gases, for example methane, propane, ethane, ethylene, butane and oxygen, can also be loaded or unloaded in the liquefied state in the manner described.

Alternatively, it is possible to load Rabbit in the form of so-called phase served ie hihhem pressure and low temperature, or to ent ^{1 Qr} 's ·

It is also possible to add liquid oil products, for example crude oil, gasoline, heating oil and gas oil, in the manner described

It should be noted that it is not absolutely necessary for the buoy to which the free end of the line is attached or suspended to float on the surface of the water. In many cases it is also possible to have one arranged below the surface of the water
Use buoy.

it should also be noted that the means for automatic

Water can be lifted out to improve the propulsion efficiency of the main propellers. For example, you can use screws that are so arranged
