Definitions
- the invention relates to the technical field of watercraft, in particular the associated equipment, and in this respect an arrangement and a procedure for emptying tankers in emergencies, openings and hose connections being provided on the ship's side near the tank containers of the ship, through which the In an emergency, the cargo, the dangerous liquid, in particular crude oil, fuel, chemical, from which tankers in distress are removed.
- the damaged ship must at least be able to maneuver to a limited extent.
- DE OS 30 26 836 AI discloses an arrangement for transferring liquids to and from tankers, which works with flexible hoses and is designed as a stationary system on land.
- Such technical solutions as also described by DE G 78 03 631 Ul, are not suitable for emptying tankers at sea in emergency situations.
- a covering of rigid pipes or movably connected rigid pipe sections is shown in DE OS 37 25 307 AI. However, it affects rigid underwater pipelines and is intended to protect them against leaks.
- the invention has for its object to provide an arrangement and a procedure with which a damaged tanker can be emptied in any position without people entering the average and / or auxiliary tankers, islands or facilities of any kind on the average or in whose immediate vicinity must come.
- each tank container in the ship is equipped with compressed gas cylinders and connected with each other. Valves which can be operated remotely are arranged in the connecting pipelines.
- each tank container preferably below the keel line, has a hatch, which is normally closed watertight with a lid, the lid of which has a radio-controlled unlocking bolt and an eccentrically arranged swivel joint.
- hoses which have been drummed or laid in zigzag positions, one of which is permanently connected to one tank and each with a coupling device, a hose drive device and an airbag at the other end of the hose and a safety line running parallel over the entire length of the hose.
- the lines can be drummed separately.
- All valve drive, hatch unlocking as well as hose and safety line drive devices are connected to external, independently existing energy sources that are always kept fully charged in normal ship operation.
- a separate, coded radio frequency to be used is assigned.
- a parallel wiring with a central receiving station on board is arranged to pass on all radio commands to the individual drives.
- Catapultable dinghies with winches, pumps, compressors as damage and life rafts and inflatable, elastic, firmly anchored and ventilated pontoon tanks or balloons are attached to the tanker.
- the tanks are equipped with heating devices, preferably on an inductive basis, using the known effect of electromagnetic waves in the high-frequency range - microwaves -, which are operated via accumulators or generators. This allows the goods to be transported to be transported easily in a relatively short time.
- the valves of the pipelines for the tank connection and the radio-remote-controlled locking bolts of the hatches are equipped with electro-mechanical, electro-pneumatic, electro-hydraulic and / or pyro-technical drive or blasting devices.
- the hoses are made of elastic material that can be expanded in terms of volume and diameter, are double-walled, provided in the inner hoses with a wire mesh / mesh / mesh for heating the goods to be transported by means of microwaves, thus maintaining their transportability, and approx 300 m long.
- the lines of the hoses are also approx. 300 m long and consist of a high-strength material, preferably nylon, or are designed as a thin steel cable.
- a projectile driven by a gas cartridge and an airbag which can be triggered by radio control are arranged at the ends of the fishing lines.
- the external energy sources for the valve drive and hatch unlocking devices are designed as electric accumulators or gas cartridges and for the hose and suspension line drives as gas cartridges.
- all drive devices themselves and radio signal reception devices at the drive devices are connected via a separate wiring network are connected.
- the object is achieved in that, by means of a radio signal, the hatches, which are in the position which is most favorable for the purpose, are opened by the unlocking bolt being actuated by the hatch unlocking device.
- the hoses are carried with the safety lines or the safety lines alone after the hatch has been opened, also by means of radio signal triggering through their hose drive device or with a gas cartridge into the open sea and thereby unrolled from their drum in the ship.
- the airbags at the end of the hose and / or suspension line are filled with gas by means of renewed radio control, so that the hose ends with their coupling devices or the suspension lines are transported alone to the water surface.
- the hoses are picked up by the rescue teams from the auxiliary tanker, from an auxiliary platform or island or an auxiliary device of any kind by means of their fishing lines and connected to tanks or to intermediate storage facilities, such as pontoon tanks or balloons, if tanks are not immediately available.
- the double-walled hoses are inflated with compressed air in the outer hose chamber by means of compressors located on salvage units and brought to the predetermined diameter.
- valves in the pipelines which enable an optimal emptying of the tank containers connected in accordance with the position of the damaged tanker, are opened by means of their valve drive device.
- compressed air is fed into the tanks through the outer hose chambers of the hoses, alternatively, gas is injected into the tanks by means of the pressure gas bottle attached to the respective tank, which gas, in turn, and in cooperation with three-way valves and pumps of the recovery units, allows the heated tank contents to flow through the inner hose chambers of the hoses into rescue tanks or intermediate storage facilities.
- the hoses are adjusted by adjusting the ratio between the weight of the inner chamber through which the tank contents flow and the buoyancy of the outer hose filled and filled with compressed air, depending on the swell, and their goods are kept at a suitable temperature level by means of microwave radiation.
- the solution according to the invention is distinguished by the advantageous effects listed below.
- the machine and energy supply systems often fail. Due to the energy reservoirs on the blasting and propulsion devices according to the invention and the radio receiving systems, which are kept constantly charged in normal operation, radio-controlled manipulation of the tanker and the connection and transfer systems from the damaged tanker to the auxiliary device are possible, which are easily received, connected and can be used for removal from the tanker, including their stabilization during removal. It is therefore unnecessary for individuals, teams or equipment to be spent on the average person before the salvage, and in particular the dangerous liquid cargo, can begin. The risk reduction for the salvage personnel is accompanied by savings in labor costs.
- FIG. 1 shows the side view of the tanker.
- the arrangement of the hatches with their hatch covers relating to the position of the tanks and the keel line, the position of the connecting pipe lines between the tanks and the position of the valve and hose lines drive devices shown.
- FIG. 2 shows the individual components of the arrangement according to the invention in the top view of the tanker.
- FIG. 3 shows in particular a hatch arranged in the side wall of the tanker and shown in the closed state with the projectile and the airbag as well as with the hose drive device and the hose package.
- Figure 4 shows a side and front view of an open hatch with unlocking in operation.
- a tanker of any tonnage is in distress near the coast and runs into a cliff area near a nature reserve, which has made it unable to maneuver.
- a large part of the crew on the tanker becomes unusable due to the effects of an accident and there is a total machine failure.
- there is a limited fire on deck which cannot be controlled with the ship's own means.
- the ship's personnel are forced to disembark.
- the means according to the invention are used by means of coded radio commands by a still usable and authorized member of the ship's crew as follows:
- One or more hatches 8 are unlocked by means of the bolt 9 and move downward about the eccentric rotary joint 10 due to the intended center of gravity. After flooding the vestibule, the projectile 25 is set in motion and pulls the fishing line 16 into the open sea. Compilation of the reference numerals used
- the projectile's own airbag 26 is activated.
- the fishing line 16 is picked up by the crew.
- the pontoon tanks 23 catapulted overboard are anchored.
- the double-walled hose 12 which may also have its own
- the contents of the tank are transferred via the pipeline system between the individual tanks, likewise by radio remote control, through the tank's own compressed gas bottles into tanks that have already been emptied, and from there are withdrawn from the tanker.
- tanks can be evacuated simultaneously via their own emergency emptying device if the situation permits.
- the tank most at risk from the fire is preferably emptied first. All procedural steps can later be traced by the rescue teams who have arrived at the remaining, not emptied tanks. All necessary radio commands can also be carried out by parallel radio remote controls of helicopters, auxiliary ships or the like. Funds are initiated or carried out.
- the invention thus relates to an arrangement in connection with procedural steps that make it possible to remotely address a previously unsatisfied need of those involved, a damaged tanker, without having to put men, individuals or equipment technology in danger as an emergency measure empty.
- This technical solution can be used as retrofit for existing tankers, in particular older ones, as well as for new tankers to be built as new equipment.
