 METHOD AND DEVICE FOR FLOWING AND / OR

 GAS PRODUCTION PRODUCTS

The invention relates to the operation of subsea hydrocarbon and other deposits of fluid and / or gaseous products, in particular, subsea production facilities, and can be used to localize, collect and collect gas, oil or oil and other fluid and / or gaseous products, including including the gushing of their powerful stream. It will be most widely used in the selection of hydrocarbons using modular systems designed for the collection, selection, storage and transportation of hydrocarbons, as well as the prevention and elimination of accidents and the localization of leaks from uncontrolled sources and mothballed emergency and other wells during underwater production of fluid and / or gaseous products (hydrocarbons, etc.).

It is known that all existing methods of hydrocarbon production from the bottom of water bodies in one way or another depend on the reliability of the production system and transport system (pipeline) from the source of hydrocarbon production (leakage) to the place of their further use (loading onto other vehicles, etc.) and environmental conditions in the mining zone. Violation of the subsea production system and / or transport system (pipeline) from the source of production (leakage) of hydrocarbons to the place of their further use (loading onto other vehicles, etc.), as a rule, leads to environmental pollution and may be the cause accidents and catastrophes of anthropogenic and environmental nature. Moreover, both floating drilling rigs and stationary ones, in most cases, are dangerous to operate in case of adverse natural, weather conditions or other force majeure circumstances. Storms and storms very often cause great material damage to offshore oil and gas production fields and, in addition, under such conditions they are often forced to stand idle. Therefore, the collection of fluid and / or gaseous production products (hydrocarbons, etc.) directly at the bottom of water bodies and transporting them to the surface without using pipelines is one of the rational and safe options, which at the same time It is also one of the solutions to the problem of preventing and eliminating accidents during subsea hydrocarbon production and minimizing, in the event of an accident, the release of production products into the environment. It should be noted that the solution to this problem is relevant both for hydrocarbon production and for eliminating emergencies at oil and gas pipelines and quickly and safely eliminating accidents in the event of their occurrence and protecting them from pollution by products from the extraction of water in the presence of any uncontrolled sources of leakage. For example, the ecological catastrophe in the Gulf of Mexico, which was caused by the leakage of oil from a subsea well after the explosion and destruction of the platform, was a serious test for the entire deep-sea oil production industry and in fact and convincingly demonstrated the technological unpreparedness of the industry to take effective measures to eliminate it.

 The liquidation of an accident and its consequences at a depth, in the case of failure to take preventive measures to prevent it and the absence of special equipment created in advance and preparing to use it for quick liquidation, requires enormous costs and the use of expensive and complex equipment, which, as practice shows, is being created, as a rule, already directly in the process of eliminating accidents. For example, a gigantic (over 100 tons) metal dome for oil collection, which flowed out of a damaged well, was put down to the bottom of the Gulf of Mexico (the article “a damaged well in the Gulf of Mexico was covered with a funnel” from 05/08/2010. Internet, website http: / /top.rbc.ru/society). It was assumed that oil would be pumped into tankers placed on the surface. However, due to the imperfection of the dome design and its consolidation, oil continued to flow into the Gulf of Mexico with an intensity of approximately 5 thousand barrels per day. Other activities have also been extremely costly and ineffective.

 Due to the current lack of effective methods, devices, constructive and technological solutions that are free from the above drawbacks, the leading world companies set the task of creating a system for eliminating oil leaks, especially when developing deep-sea areas

(lutp: eco.rian.ru nam; v 20! O ^Q 722. 2571 743'AS. htm!). According to their views, the mobility of this system should allow to bring it into effect within a day. It is assumed that it will consist of special underwater equipment for localizing the leak, to which collectors and pipelines for delivering oil on board the tankers will be attached. Special teams will provide regular technical support. maintenance, diagnostics and availability of installations and underwater modules. Companies note the need for such systems to be pre-designed, built, tested and ready for rapid deployment. The system that is supposed to be developed, according to the views of company specialists, should absorb up to 100 thousand barrels per day at depths of up to 3 km.

 Moreover, in all known methods of collecting fluid production products, in particular, petroleum products, from the source of their flow, where pipelines are used in devices that sell them for transporting production products from their source to the destination, in case of violation of the components of the transportation system, the connection problem the output of the source of production products from which an uncontrolled outflow of a substance (matter, particles) occurs without stopping its flow when connected to an object (pipe, etc.) through The further movement (transportation) should be carried out to the body. The same problem occurs with the implementation of known methods and with the installation of any devices above the source of leakage of production products, if necessary, stop their leakage into the environment for the absence of the possibility of stopping the leakage when installing these devices.

From the copyright certificate N ° 1631124 (IPC ^5: ЕВВ 15/04, publ. 02.28.91, Bull. N ° 8), a method for collecting fluid production products, in particular oil products, from the bottom of a reservoir is known. The essence of the known method lies in the fact that an oil gathering device equipped with a bell, which covers the perimeter of the concentration zone of the oil product, through which oil products by gravity move through a flexible pipeline to storage tanks located on the vessel, is lowered over the outflow of oil products using a ship’s boom.

It is also known a device for collecting fluid production products, in particular, petroleum products from the bottom of a reservoir (the above copyright certificate N ° 1631124), which contains a socket equipped with a flexible pipe designed to remove contaminants from the collection site of petroleum products. A flotator is mounted on the bell, made in the form of a distribution air collector by nozzles. The selection of petroleum products is as follows. Through a system of nozzles, air is supplied under pressure to the oil collection zone. As a result of using the flotation effect in the device, heavy oil contaminants that have settled to the bottom are torn off by air bubbles due to the energy obtained by pumping air. Oil-contaminated clots concentrate under the bell, and potential energy ejection provides conditions for the flow of oil products by gravity through a flexible pipe to storage tanks located on the vessel.

 These method and device provide for the collection of oil products spilled at the bottom of the reservoir, but are completely unsuitable for working with a gushing oil stream, which flows under pressure from a well or a damaged pipe. In addition, the method provides a single route for delivering the collected material from the bottom to the surface - through the pipeline directly to the storage tanks located directly on the vessel. Therefore, in the event of accidents and oil spills or their production in difficult conditions (for example, during storms and storms, significant disturbances of the water surface, as well as during the freezing of the water surface, during production at great depths, at significant leakage intensities of the flow of production products, and t .d.) the implementation of this method will be extremely problematic.

A known method and device for year-round underwater collection of fluid production products, in particular petroleum products, using floating underwater tanks (tanks) (RF patent W 2021959 (IPC ^5: B65D 88/78, publ. 10/30/1994). Using these tanks capable of being submerged until favorable conditions exist for their further transportation (for example, melting of surface ice), oil produced under ice conditions is transported.The floating tank has a hull in the form of a ballast tank, which is located in the lower part of the tank is connected to overboard water. Tanks of constant and variable buoyancy are located on top of the hull. To collect oil, the floating tank is anchored to the bottom of the reservoir at a distance from the well. Oil from the well is fed through a special pumping hose. As oil enters the ballast tank with water is displaced last, the buoyancy of the body increases, and, accordingly, the tension of the anchor cable increases - in this position, the tank can be under water for any length of time, after which if necessary, oil is pumped to a transport vessel.

The disadvantage of this method is that in it the oil and water of the ballast tank are not physically separated from each other, underwater tanks are used that cannot be used effectively at great depths, moreover, they are designed to pump oil into them only through a hose and its subsequent pumping from underwater tanks of temporary stay to a transport vessel, and this requires the use of appropriate equipment, which generally complicates and increases the cost of the production process, and can also lead to spillage of products production in the event of damage to the production and / or transportation means (e.g. hoses). In addition, the remoteness of reservoirs for collection and / or transportation from the direct source of oil supplies causes certain inconvenience during their operation and for maintenance personnel and makes it difficult to monitor the progress of work.

A known method of sampling fluid production products, in particular petroleum products, from a source of their leakage, which is under water, which consists in installing a capture module above the leak source, which includes a tank that is filled with water before lowering to the bottom of the reservoir, and the petroleum products are sampled the process of displacing water from the tank by them (RF patent jVs 2247807, IPC ^5: ЕВВ 15/04, publ. March 10, 2005, prototype).

 The method involves the sampling and localization of the flow of oil under pressure under pressure directly above the leak, which avoids its spread in the surrounding aquatic environment.

 A device is also known for collecting fluid production products, in particular petroleum products, from a source of their leakage under water, containing a container with a window for collecting production products and at least one window for selecting collected leakage products, the container being located on a sealed tubular frame (RF patent NQ 2247807, prototype). The frame with the floating chamber is installed in the opening of the floating platform, on which winches are installed, to which the frame is attached by cables, and also a source of compressed air is connected with the cavities of the frame and the floating chamber.

 In the process of collecting oil products using a known device, oil products rise from under the shell of the tank along the corrugated sleeve up to the storage chamber, from where pumps that are located at a distance from the capture module are pumped through a special elastic pipeline (sleeve) to the floating tanker. Thus, the process of transporting oil from the place of the leak to the place of its final concentration is quite complicated, which is a significant disadvantage of the known method and device. Thus, the need to use pumping equipment, an elastic pipeline and the obligatory presence of a tanker to drain the collected oil not only complicate the work process, but also make it economically disadvantageous and substantially hazardous to the environment.

The disadvantages of the known method and device should also include the fact that its implementation requires a catching device of a complicated design construction, but at the same time, the water with which the capacity of the trapping device is filled and the oil products entering it, displacing the water, are not physically separated, and there is no possibility of both controlling the process of filling the tank with production products and production as a whole, and the elastic shell can be easily damaged or even destroyed. A significant disadvantage of the known method and device is the fact that they are almost impossible to realize when flowing a powerful stream of fluid and / or gaseous products.

 The disadvantages of the method include the fact that its implementation requires the fulfillment of two basic conditions: the first is the obligatory presence of a tanker at the time of oil extraction and the second is the absence of factors interfering with production on the surface (for example, adverse weather conditions, ice cover, etc. ) The method causes the transfer of petroleum products in the direction from the storage chamber to the tanker, which in the absence of the latter for one reason or another (the tanker may fail, arrive late, etc.), the situation in the conditions of uncontrolled leakage of the product may become critical as well as in the event of an accident.

 And when selecting oil in ice conditions, difficulties will necessarily arise associated with the need to solve the problem of concentration of the collected oil, because the method does not provide for the use of any separate (autonomous) tanks or reservoirs in which it would be possible to “place” the removed oil and leave these tanks under water until a certain time.

 Thus, there is a problem of both the lack of effective methods and means for underwater platformless production of fluid and / or gaseous production products, and the elimination of accidents during their underwater production in existing fields, as well as the installation of equipment on sources of leakage of fluid and / or gaseous production products (wells) when flowing from them a powerful stream and ensuring the localization of uncontrolled leaks from canned sources.

The basis of the invention is the task in the method of sampling fluid and / or gaseous products of production by changing the sequence of implementation and introducing fundamentally new components of the work process, equipment and optimization of the overall technological operations of the work process, in particular by applying an improved process of sampling fluid and / or gaseous products of production and a new special capture device, achieve increase efficiency and ensure safety in the underwater production of hydrocarbons and other fluid and / or gaseous substances, the ability to quickly eliminate accidents in the event of their occurrence in the production of fluid and / or gaseous products in underwater fields and the effective lifting (lifting, delivery) of fluid and / or gaseous production products (hydrocarbons, etc.) in variable removable tanks and transportation of seized (received) production products (hydrocarbons, etc.) without the need for pumping equipment and auxiliary pipelines, as well as the creation of conditions for the storage of extracted products (hydrocarbons, etc.) in variable removable containers for the required time.

 The problem is solved in that in the method of sampling fluid and / or gaseous production products from a source of their leakage, which is under water, which consists in establishing a container above the source of leakage, which is filled with a working substance, for example water, before being lowered to the bottom of the reservoir, and fluid sampling and / or gaseous products of production are carried out in the process of displacing them from the tank of the working substance, for example, water, according to the invention, a container separated by a movable source is installed over the leak source, controlled m with a piston to chambers of variable volume for a working substance, for example water, and for production products, from which a chamber for a working substance is preliminarily filled with a working substance, for example, water, and fluid or gaseous production products are sent to a chamber for production products, during the filling of which with production products, the piston moves freely, under pressure from the production products, or is controlled in the direction of the chamber for the working substance and displaces the working substance outside this chamber, and then the production is selected Production chambers from the chamber for production products using one or more removable, removable devices, for example, reservoirs for selecting production products, are periodically connected to holes located below the position of the separation piston, and after filling, they are disconnected and stored or transported to their destination. The tank with a chamber for collecting production products from the source of their leakage will be called the main one, since it is installed above the source of leakage of production products.

If necessary, a pipe can be connected to at least one of the openings of this container and subsequently supplying production products to their destination. When installing the tank above the source of leakage, the intensity of the effect of the flow of the substance that is extracted on the tank can be controlled when it is installed and fixed above the source of leakage of the products of extraction, by ensuring that they flow freely from the specified tank in an external relative to the limited chamber for the products of extraction of this capacity space in the range of intensity from free flowing to zero.

 The problem is also solved due to the fact that in the device for collecting fluid and / or gaseous products from the source of their outflow, located under water, containing a container with a chamber for collecting these products, the camera has at least one inlet window for sampling and, at least one exit window for extraction of production products, according to the invention, the container is divided by a controlled dividing piston into a chamber for collecting production products and a chamber for the working substance, in which at least one a hole for input / output of the working substance, and the exit window / windows for the selection of production products are located in the area of the chamber for production products and are equipped with locking and connecting means for connecting one or more removable, removable devices, in particular tanks and / or, if necessary pipes for the selection of mining products.

 As removable, removable devices for selecting production products from the chamber for production products for their further transportation and use, tanks can be installed that can serve as storage tanks.

 A pipe may also be a device for extracting mining products from the chamber for mining products for their further transportation and use.

 One or more devices for sampling production products may be connected to a device for collecting fluid and / or gaseous production products from a source of leakage (leakage).

If necessary, an intermediate element may be installed between the input window for the extraction of production products and the source of their outflow, comprising an enclosure with openings with connecting means for connecting to the outlet of the exhaust source and to the container for production products and with at least one opening equipped with locking means, locking and connecting means can be made with the ability to control the intensity of the flow during the flowing of a powerful stream of fluid and / or gaseous products, which yvayutsya. To install a container for sampling production products above the source of leakage in the absence of funds to which it can be fixed, it can be equipped with a means of covering the zone of leakage of products of extraction and fixing above it, and a supra-base for fixing it, covering the zone of leakage (leakage) .

The invention is illustrated by drawings, which depict:

 Figure 1 is a block diagram of a device for collecting fluid and / or gaseous production products.

 Figure 2 is a block diagram of a device for sampling fluid and / or gaseous production products with a removable removable module and pipe.

 Fig. 3 is a general view of the design of a device for collecting fluid and / or gaseous production products with an intermediate element and a removable removable device and control mechanisms.

The method of sampling fluid and / or gaseous production products from their source is carried out using a device described below.

The device (Fig. 1) for collecting fluid and / or gaseous production products from their source 1, is under water, contains a container 2 with a chamber 3 for collecting fluid and / or gaseous production products, which has (at least one) input 4, and at least one output 5 window selection of products of extraction from the source of leakage in a removable, removable tank 9 (figure 2). The tank 2 also has a chamber 6 for the working substance formed by the piston 7, which is designed to separate (isolate) the extracted substance from the working substance, and to withdraw (push) the working substance outside the working chamber, and, if necessary, to withdraw the substance, which it is extracted and / or pushed into removable removable containers 9. The container 2 in the upper part of the chamber 6 has openings 8 for connecting this chamber to the environment. The piston 7 is installed with the ability to freely or controllably move relative to the walls of the tank 2 and to ensure the separation between the produced product (hydrocarbons, etc.) and the working substance (water or other liquid), which provides resistance to external pressure on the walls of the tank of the environmental fluid when immersed devices to the depth. Shown in figure 2, the piston 7 can be made with the rod 10 and the control means 1 1, and without it. The tank 2 (FIG. 2) also has means 13 installed in its lower part for connecting removable removable containers 9. The means 13 can be made, for example, in the form of couplings with valves 12 to prevent arbitrary leakage of production products. A device for collecting fluid and / or gaseous production products from a source of leakage (leakage) may comprise means 1 1 for controlling the movement of the piston 7. A device with removable containers 9 connected to it form an improved device for collecting fluid and / or gaseous production products. Replaceable containers 9 are built on the same principle as capacity 2, but may not be equipped with additional means for connecting other tanks.

 The dimensions of the chamber for sampling the products of extraction of the main capacity and storage tanks (tanks) are arbitrary and are determined by the requirements of the customer and the possibilities of their physical implementation with the prior art.

 The capacity can be made in the form of a third-order figure (for example, a cylinder (glass) or a cube, etc.).

 The connecting means are provided with shut-off valves, with which you can control the flow rate, which is especially necessary when extracting gaseous substances, to take into account the external pressure of the working fluid. A removable, removable container, as seen in FIG. 2, has a design identical to the main tank.

 A device for selecting production products from the chamber for production products for their further transportation and use may be a pipe 14.

 One or more devices for sampling production products may be connected to a device for collecting fluid and / or gaseous production products from a source of leakage (leakage).

Between the input window 4 for the extraction of production products and the source 1 of leakage of the extracted substance, an intermediate element may be installed containing a body in the form of a bell 15 with holes 17 and with connecting means (not shown conventionally) for connecting to the outlet of the leakage source and in the tank 2 for production products and with at least one hole 17 for their leakage during installation (connection) of the main tank, equipped with locking means 16 of these holes, to compensate for the dynamic high-pressure head of the products custom blowouts at their powerful stream. In this intermediate element, the locking and connecting means can be made with the possibility of control, and the element itself can be one that is assembled from segments.

 The container for collecting production products can be equipped with a means of covering the zone of outflow (outflow) of production products and fixing above it, and, if necessary, a supra-base for fixing it, which covers the area of outflow.

 The method of sampling fluid and / or gaseous production products is as follows.

Before lowering the device for collecting fluid and / or gaseous products of production to the bottom of the reservoir to compensate for the external pressure of the reservoir’s water on it, the container 2 (FIG. 3) is filled with a working substance (for example, reservoir’s water). In this case, the working substance presses on the piston 7, which can be equipped with a rod 10 installed in the container 2 and also in a variable removable container 9 with the possibility of free or forced (controlled) movement relative to its walls. A device for collecting fluid and / or gaseous products of production is installed and fixed on the bottom of the reservoir above the source of their outflow 1 so that the device 2 by means of covering the area of the outflow of production of products and securing above it, for example, the socket 15, completely covered the area of the outflow. The outgoing flow under pressure fills the cavity of the device (main tank) 2, moving the piston up. If the pressure from the flow of the substance that is extracted, and flowing from the source 1, is not enough to move the piston 7 and squeeze the working fluid out of the container 2 into the external environment, the piston is forced to move and thereby squeeze out the working fluid from the container 2 into the external environment, which ensures the required volume chambers 3 for the intake of fluid and / or gaseous products of production. In this case, the working substance, which is located above the piston, is released through special openings 8 located in the upper part of the container 2. Thus, a pressure balance is maintained in the container with respect to the surrounding aqueous medium, and a device for collecting fluid and / or gaseous production products is located in a stable, reliable position. As the tank 2 is filled, a periodic selection of products is carried out in separate removable removable tanks 9, which are attached to the main tank below the level of the separation piston in the part where production products (hydrocarbons, etc.) are accumulated, or through the pipe 14. The control of the movement of the piston can be carried out by known means, for example, a rail drive, but not limited to this.

 To ensure continuous intake of fluid and / or gaseous production products (hydrocarbons, etc.), uncontrollably flowing from the source 1, through couplings and valves 12, which are located in the tank below the level of the separation piston in the part where the products of production are accumulated (hydrocarbons, etc.) attach removable containers 9. After filling removable containers, valve 12 is closed and removable containers are disconnected. In their place, in the same way, new removable removable containers are attached, free for further filling with extracted products (hydrocarbons, etc.). Filled containers are stored or transported to their destination. In the case of using the pipe as a removable variable or stationary device, production products are transported through it.

 The attachment and detachment of removable removable containers can be implemented by various known methods and devices. For example, screw screwing into the connecting element is used, then the mechanical opening of the shutters on the main and removable removable containers is performed, and after filling the removable removable container, the shutters are closed and the filled removable container is turned off, the next removable removable container is ready to be filled with the extracted substance, and the process is repeated . A nipple system, coupler, etc. may also be used. To prevent overfilling of the storage chamber of the main tank with the produced substance, when connecting replaceable modules that are free to fill, by forced movement of the piston towards the source of the extracted substance, excess substance is squeezed into the removable removable tanks, which is extracted if its quantity is in the chamber for mining products of the main tank becomes more than a certain allowable.

Forced control of the movement of the separating piston inside the containers provides, unlike the prototype, the efficient extraction of substances at almost any rate of their leakage flow from the source: from zero to the maximum possible. At the same time, at a zero natural flow rate from the source, the intake of the substance extracted in the tank can be ensured due to both the operation of the piston as a pump and its injection by any known method and device. The forced movement of the piston can be carried out in any known manner, for example, by using a rail or a screw mechanism or other known mechanism that provides movement of the piston along the axis in both, in both forward and reverse directions. Between the container 2 and the leak source 1, if necessary, an intermediate element is installed, which has a housing with holes with connecting means (not shown conventionally) for connection, containing a bell 15 with less than one hole 17 for leakage, if necessary, of products of production into the environment . The specified hole is equipped with a locking means 16. The intermediate element is connected to the outlet of the leak source and to the tank for mining products. The locking and connecting means in the intermediate element are controlled. The intermediate element provides the possibility of adjusting the intensity (control of the intensity) of the flow of matter in the space external to the space connecting the connecting module (into the space surrounding the module) in the range: from the intensity of free flowing to the desired (predetermined) level, even at zero.

 This element is designed in such a way that it makes it possible to install the main tank over the leak source both in the presence and in the absence of means to which it can be fixed, for example, by covering the leak zone of production products by any method known from the prior art, for example, conical bell with a supra base covering the leakage zone.

 Thanks to the proposed method, device and module for concentrating production products (hydrocarbons, etc.) in variable tanks, it is possible to abandon the need to use pumping equipment and auxiliary pipelines, as is the case in the prototype, and therefore, significantly simplify, make it safer and cheaper the process . And the accumulation and storage of the extracted substance (petroleum products, etc.) in separate replaceable tanks (tanks) allows you to dispose of them, focusing on the specific situation: they can be immediately loaded onto transportation means, left under water until the moment that is most suitable for transportation stored on platforms or on the shore, and the like. In any case, the implementation of the method does not depend on weather conditions, nor on the presence or absence of transportation means.

An important advantage of the proposed method and device is that the sampling of production products (hydrocarbons, etc.), their localization and transportation can be carried out at great depths, with their constant flowing from sources and wells, both at zero and significant degrees of intensity of the outgoing flows. This factor makes the method equally acceptable both for the extraction of production products (hydrocarbons, etc.), and for their extraction from an emergency source (well) or an emergency section of the damaged pipeline, as well as to prevent uncontrolled leakage of production products from canned sources (fields).

 The presence of removable removable devices, in which the accumulation of extracted substances occurs, makes it possible to produce substances in practically unlimited volumes, to carry out production and transportation without using platforms and pipelines from the source from which the extraction is carried out, and to the surface.

 An additional distinctive feature is the invariance to the depth at which mining is carried out, in terms of the effect of pressure on all storage tanks.

 The ability to install an intermediate element equipped with a locking means, provides control of the intensity of the impact of the flow of the substance that is extracted on the tank when it is installed and fixed above the source of leakage of production products.

 This element ensures the establishment of the main tank above the source of the leak, both in the presence and in the absence of means to which it can be fixed, and implements the possibility of stopping the leak of production products into the environment.

 The proposed invention provides environmental protection due to the possibility of complete isolation of leakage of production products (hydrocarbons, etc.) to it, including by stopping uncontrolled leakage of production products from canned sources (fields), the absence of the need for a mandatory transport pipeline from the source production products to the place of collection and storage of production products (hydrocarbons, etc.).

The proposed method of sampling fluid and / or gaseous production products (hydrocarbons, etc.) from a source of their leakage, which is under water, has a wide field of application and can be effectively implemented in any deposits of fluid, liquid and gaseous substances. It can provide quick and at minimal cost elimination of accidents during the production of hydrocarbons and other substances, including at great depths, while minimizing the risk of environmental pollution and preventing negative environmental consequences of accidents and environmental disasters. Using the method allows to increase hydrocarbon production in regions where the surface of water bodies is covered with ice and in permafrost.

 The invention, which is proposed, allows to obtain a significant economic effect by reducing the cost of eliminating environmental and technological accidents and disasters, minimizing environmental pollution, the possibility of reducing the strength requirements of materials for the manufacture of containers, regarding their special design features for use at great depths and in general, reducing the cost of equipment in the production of hydrocarbons and other substances under water, including at large bins, and in regions where the surface is covered with ice reservoirs, and in permafrost.
