Abstract

A method for the emergency limitation of the spread of liquids and gases in bodies of water when leakages occur in underwater pipelines and boreholes describes limiting escaping substances by means of a ready-made, textile composite structure. In a first step, buoys are anchored around a damage site. Thereafter, a collector is placed in position and lowered, with guidance, over the damage site. A hose, which opens out in the process, directs the escaping substances to the water surface. The collector, finally, is fixed on the bed of the body of water and seals the damage site.

Description

Beschreibung  description
Verfahren zur Notfalleingrenzung der Verbreitung von Flüssigkeiten und Gasen in Gewässern bei auftretenden Leckagen in Unterwasserrohrleitungen (Pipeline) und Bohrlöchern.  Procedures for emergency containment of the dispersion of liquids and gases in waters in the event of leaks in underwater pipelines (pipelines) and boreholes.
Leckagen in unterseeischen Rohrleitungen und bei Bohrlöchern sind nie gänzlich auszuschließen. Durch Umwelteinflüsse, technisches Versagen oder terroristische Einwirkungen sind Schäden vorstellbar und auch bereits eingetreten, die erhebliche Auswirkungen auf die Umwelt (Gewässer, Fauna und Flora) und die Wirtschaft (Schadenersatzansprüche und Kosten der Beseitigung von Umweltschäden) haben. In einem derartigen Fall ist es zur Vermeidung größerer Schäden notwendig die aus der Leckage austretende Substanz schnellstmöglich einzugrenzen. Ein einem weiteren Schritt muss die Entsorgung zeitnah eingeleitet werden können. Diese muss so lange aufrecht erhalten werden bis eine dauerhafte Reparatur der Leckage möglich wird.  Leaks in submarine pipelines and boreholes can never be completely ruled out. Due to environmental influences, technical failure or terrorist effects, damage is conceivable and has already occurred, which has significant effects on the environment (water, fauna and flora) and the economy (claims for damages and costs of remedying environmental damage). In such a case, to avoid major damage, it is necessary to confine the substance emerging from the leakage as quickly as possible. A further step, the disposal must be initiated promptly. This must be maintained until a permanent repair of the leakage is possible.
Nach dem Stand der Technik wird bei derartigen Leckagen die ausgetretene Flüssigkeit an der Gewässeroberfläche entweder mit Hilfe von Ölsperren eingegrenzt und abgesaugt und/oder mit Hilfe von chemischen Substanzen entweder gebunden (sinkt auf den Grund des Gewässers) oder gelöst. Diese Verfahren sind nur begrenzt für den Einsatz auf hoher See und in rauhen Gewässern geeignet, da die dort anzutreffenden Bedingungen, Wind, Strömung, Wellengang, etc. den Einsatz erschweren oder gänzlich unmöglich machen. Weiterhin tragen die eingesetzten Chemikalien oft zu einer zusätzlichen Schädigung bei. Die heute zur Verfügung stehenden Verfahren erlauben es nicht innerhalb kurzer Zeit nach dem Eintreten des Schadensfalls direkt an oder über der Leckage die austretenden Substanzen aufzunehmen. Insbesondere bei größeren Tiefen ist die schnelle Eingrenzung der austretenden Substanzen bis heute nicht gelöst.  According to the state of the art, in such leaks, the leaked liquid at the surface of the water is either confined and extracted with the help of oil barriers and / or either bound with the aid of chemical substances (sinks to the bottom of the water body) or dissolved. These methods are only limitedly suitable for use on high seas and in rough waters, as the conditions encountered there, wind, current, waves, etc. make the use difficult or completely impossible. Furthermore, the chemicals used often contribute to additional damage. The methods available today do not allow to absorb the escaping substances directly at or above the leakage within a short time after the occurrence of the damage event. Especially at greater depths, the rapid limitation of the exiting substances is not solved to this day.
Das Erfindungsgemäße Verfahren zur Notfalleingrenzung der Verbreitung von Flüssigkeiten und Gasen in Gewässern bei auftretenden Leckagen in Unterwasserrohrleitungen (Pipeline) und Bohrlöchern ermöglicht es schnell und effektiv austretende Substanzen einzugrenzen und gezielt der Aufnahme bzw. Entsorgung zuzuführen.  The inventive method for emergency containment of the dissemination of liquids and gases in water in case of leaks occurring in underwater pipelines (pipelines) and boreholes allows to quickly and effectively limit escaping substances and selectively supply the intake or disposal.
Das eingesetzte Material ist leicht, flexibel einsetzbar und schnell einsatzfähig. Auf Grund der Möglichkeit diese Notfalleingrenzungen vorzufertigen kann innerhalb weniger Stunden eine Eingrenzung der Schadstelle erreicht werden. Dadurch können sowohl wirtschaftliche wie auch ökologische Schäden signifikant reduziert werden.  The material used is light, flexible and quick to use. Due to the possibility of prefabricating these emergency confinements, a limitation of the damaged area can be achieved within a few hours. As a result, both economic and ecological damage can be significantly reduced.
Das Verfahren ist nicht auf eine bestimmte Gewässertiefe beschränkt und auf Grund der druckunempfindlich eingesetzten Materialien auch in großen Wassertiefen einsetzbar.  The method is not limited to a certain depth of water and due to the pressure-insensitive materials used also in large water depths.
Dabei werden in einem ersten Schritt (Skizze 1) um die Schadensstelle herum Bojen auf dem Gewässergrund verankert. Die Anzahl der Bojen richtet sich dabei nach der Größe der Schadstelle und den an der Schadstelle anzutreffenden Bedingungen (Bodenbeschaffenheit, Strömung, Tiefe, etc.). In einem zweiten Schritt wird eine textile Verbundstoffkonstruktion in Form einer rechteckigen Haube, der Sammler, über der Schadstelle in Position gebracht, diese ist mit den Ankerseilen der Bojen verbunden. In a first step (sketch 1), buoys are anchored around the damaged area on the body of water. The number of buoys depends on the size of the damaged area and the conditions encountered at the damaged area (soil condition, current, depth, etc.). In a second step, a textile composite construction in the form of a rectangular hood, the collector, is placed in position over the damaged area, which is connected to the anchor ropes of the buoys.
In Schritt drei erfolgt die geführte Absenkung des Sammlers, an den Ankerseilen, über die Leckage (Skizze 2). Dabei wird während des Absenkens ein Schlauch entfaltet. Dieser wird direkt mit der Schiffseinheit verbunden die für die Aufnahme der austretenden Substanzen vorgesehen ist. Bereits während der Absenkung beginnt der Sammler die austretenden Substanzen in den Schlauch zu führen. Innerhalb des Schlauches steigen diese nach oben und können aufgenommen werden.  In step three, the collector is guided, at the anchor ropes, over the leakage (sketch 2). During the lowering, a hose is deployed. This is directly connected to the ship unit which is provided for receiving the exiting substances. Already during the lowering of the collector begins to lead the exiting substances in the hose. Within the tube, these rise up and can be absorbed.
In Schritt vier (Skizze 3) wird der Sammler an den Ankern der Bojen fixiert. In die Kanten des Sammlers eingearbeitete Gewichte drücken die Ränder des Sammlers auf den Grund des Gewässers und dichten die Schadstelle ab. Der innerhalb des Sammlers werden die austretenden Substanzen dem an der höchsten Stelle angebrachten Schlauch zugeleitet und über diesen nach oben transportiert. An der Wasseroberfläche können die ausgetretenen Substanzen kontrolliert aufgenommen werden. In step four (sketch 3), the collector is fixed to the anchors of the buoys. Weights placed in the edges of the collector push the edges of the collector to the bottom of the water and seal the damaged area. The inside of the collector, the exiting substances are fed to the mounted at the highest point hose and transported over this upwards. At the water surface, the leaked substances can be recorded in a controlled manner.
