Definitions

  • the present invention generally relates to a device for collecting fluids lighter than water escaping from an underwater source.
  • the device is particularly useful for collecting fluid pollutants, such as e.g. oil, oil products or chemical products, leaking from sunken tankers.
  • EP 0 550 682 proposes to assign to each tank of a ship a recovery device having an external floating body connected to a transport hose, which is coiled onto a drum.
  • the external floating body is located on the deck of the ship equipped therewith.
  • a first end of the hose is connected to a tank containing the fluid to be collected.
  • the free second end of the hose is connected to the external floating body. The latter is maintained on the ship's deck in such a way that when the deck comes under water, the external floating body will move upwards due to its buoyancy.
  • the coiled hose will be progressively unwound as the first end of the hose sinks deeper and deeper with the ship.
  • This device gives prompt information to the rescue crew on a sunken tanker's position and on type/amount of oil or other chemicals. To recover the oil/chemicals trapped in the tanks, it suffices to connect the rescue boat to the second hose end attached to the external floating body, and pump the oil/chemicals. Unfortunately, this device looses its interest if the tanker sinks down to a depth which is greater than the length of the hose. Moreover this concept has a considerable cost impact, since one such device is required per tank. A further shortcoming of this concept is that it will not permit the recovery of fluids escaping from a burst open tank, which may happen when e.g. a ship breaks into several parts like the "PRESTIGE".
  • US 4,643,612 discloses a floating barge having a concave bottom.
  • the barge is adapted to be anchored at the sea surface over a sub sea well or pipeline that is leaking oil.
  • Flexible roll-up skirts extend to the ocean floor. This prevents currents from shifting the oil outside the channel defined thereby.
  • the oil is trapped under the barge and can be pumped from there via a pipe located at the apex of the concave bottom.
  • Unfortunately, such a barge cannot be used in maritime disaster cases where the wreck lies at great depths.
  • the low flow rate of the gravity driven flux of a viscous fluid, such as heavy oil, towards the surface would require the barge to stay stable in place for months, the whole operation being very dependent on the surface weather conditions.
  • a device for collecting fluids having a specific density lower than that of the surrounding water and escaping from an underwater source comprises collecting means placed over the underwater source for collecting the fluids escaped from the source and rising therefrom due to gravity.
  • a transfer tube has a lower end in communication with the collecting means for transferring the collected fluids towards the surface.
  • a submerged buffer reservoir is maintained at a predetermined depth under the surface, the submerged buffer reservoir being in communication with an upper end of the transfer tube for receiving the collected fluids.
  • the present device is designed in such a way that the collected fluids are transferred from the collecting means to the submerged buffer reservoir, through the transfer tube, due to gravity.
  • Such a transfer requires no external energy.
  • the device of the invention can be comprised of relative simple and non-moving parts. It follows that components like motors, pumps or pressure vessels are not required to transfer the collected fluids to the buffer reservoir, which saves costs and increases the reliability of the device.
  • the collecting means comprises a dome-shaped element so that the collected fluids converge towards its apex.
  • a dome-shaped element may e.g. be formed as an inverted funnel, i.e. a funnel arranged with its small opening above its large opening.
  • the dome-shaped element has about its apex an opening, to which the lower end of the transfer tube is connected.
  • the opening is thus located in the area where the collected fluids converge due to the dome-shape of the collecting means. Again, this allows transferring the collected fluids to the transfer tube through the opening simply by the effect of gravity.
  • the bottom of the dome-shaped element is positioned proximate to the underwater source.
  • the leaking and escaping fluids are thus collected near the source, which avoids that water currents shift the fluids away from the collecting means.
  • the submerged buffer reservoir comprises a chamber with an open bottom.
  • the transfer tube opens into the chamber with its upper end.
  • the collected fluid rises into the tube and penetrates into the chamber, where it accumulates.
  • the flow of fluid into the buffer reservoir may be continuous or not. So, as the fluid accumulates in the chamber, it also gradually replaces the initial, heavier water content of the chamber, which is expelled via the open bottom.
  • the water will separate from the fluid due to the difference in specific weight, so that the submerged buffer reservoir also acts like a separator, which concentrates the fluids in the upper part of the submerged buffer reservoir.
  • the tube penetrates into the chamber through the open bottom.
  • the fluid coming out of the upper end of the transfer tube is not exposed to currents that might shift it outside the catch area of the open bottom. This provides a very easy delivery of the collected fluid from the transfer tube to the submerged buffer reservoir.
  • the submerged buffer reservoir is also preferably designed so as to fulfil the function of a terminal buoy. Through its buoyancy , it keeps the transfer tube under tension.
  • the submerged buffer reservoir advantageously comprises a drainage port, through which the chamber can be emptied.
  • a shuttle ship may e.g. connect to this drainage port using standard equipment and pump the stored fluid from the chamber into its own tanks.
  • the submerged buffer reservoir may be maintained at a depth typically between 30 and 50 m. This is considered sufficient for the submerged buffer reservoir not to be affected by weather-induced sea conditions.
  • the buffer reservoir is also normally sufficiently deep to avoid collision with ships cruising in the area while being still easily accessible for recovering the stored fluid.
  • a plurality of anchoring means for anchoring the collecting means to the ground are distributed at the periphery of the collecting means.
  • the anchoring means allow keeping the collecting means over the underwater source in a predetermined position allowing a good fluid recovery.
  • the anchoring means are advantageously regularly distributed at its periphery.
  • Each of the anchoring means may comprise a suction anchor and an associated cable linking the suction anchor to the collecting means.
  • Suction anchors allow very high anchoring forces and are linked to the collecting means by e.g. steel cables or chains.
  • a plurality of tensioning rings are fixed to the transfer tube and distributed therealong, the tensioning rings having a predetermined buoyancy.
  • the tensioning rings are preferably rigid and fixed at predetermined positions along the transfer tube in order to maintain its shape and cross-section. Due to their buoyancy, the tensioning rings also permit to fine-tune the pre-tensioning of the transfer tube and consequently the collecting means. As a result the transfer tube will stay straight and mainly vertical.
  • the collecting means and/or the transfer tube shall preferably have close to neutral buoyancy, for an increased stability of the device.
  • the tensioning rings may be spaced e.g. by 5 to 20 m, depending on the prevailing currents across the length of the transfer tube.
  • the cables of the anchoring means further link the collecting means to the submerged buffer reservoir, and are preferably guided along the transfer tube in-between the tensioning rings and the transfer tube.
  • the transfer tube preferably has a diameter between 1 and 3 m, more preferably between 1.5 and 2.5 m. Such diameters are preferred for transferring leak rates of large sunken tankers such as the tankers "ERIKA” or "PRESTIGE". In addition, with diameters of about 1.5 to 2 m, problems of clogging due to high oil viscosity should not arise.
  • heating means may be provided in the vicinity of the lower end of the transfer tube. This measure is of particular interest when the fluids have a high viscosity and are susceptible to stick to the inner walls of the transfer tube. The heat provided locally increases the pressure differential along the tube, thereby causing a pumping effect.
  • chemical agents can be used to lower the viscosity of the fluid and/or its specific weight, thereby facilitating its rise in the transfer tube.
  • the inner surface of the transfer tube is made of a material chosen in order to avoid wall sticking and clogging from the fluids. This is another measure in order to deal with very viscous and sticky fluids and to enhance the transfer operation.
  • the buffer reservoir may have a capacity of 500 to 2000 t of oil, preferably between 1000 and 1500 t.
  • the buffer reservoir preferably has an outer hull made of steel.
  • the collecting means and/or the transfer tube is/are made of fabric. They keep their place and shape by being attached to the tensioned cables and the tensioning rings.
  • the present device is particularly suited to collect fluid pollutants such as oil, oil products, or chemical products that are leaking from sunken tankers.
  • the device also proves advantageous to collect fluids originating from a variety of sources, such as sunken ships but also pipelines or wells.
  • the device is thus of very general applicability, as long as the specific weight of the fluids is lower than that of the surrounding water, and if they do generally not dissolve in water. It follows that the device of the invention presents the best chances for eliminating a pollution threat in a fast, reliable, flexible and cost effective way.
  • a method for collecting fluids escaping from an underwater source and having a specific density lower than that of the surrounding water is proposed.
  • the leaking fluids are collected by collecting means placed over the underwater source and transferred towards the surface by a transfer tube in communication with the collecting means.
  • the collected fluids are delivered by the transfer tube to a submerged buffer reservoir.
  • the use of a submerged buffer reservoir permits recovering fluids (such as oil, oil products or other chemical products) leaking from an underwater source, regardless of the prevailing weather condition.
  • Fig.1 shows a preferred embodiment of a device 10 for collecting fluids in accordance with the invention.
  • Reference sign 12 indicates a sunken oil tanker lying on the seabed and having a plurality of holes in its hull and/or tanks.
  • Black trails 14 in Fig.1 represent ascending oil leaking from the wrecked tanker 12.
  • the device 10 comprises a collecting means preferably in the form of a dome-shaped element 16 and a transfer tube 18 having a first, lower end 20 in communication with the collecting means for channelling the leaking oil towards the sea surface 22. It will be appreciated that the device 10 includes a su b-merged buffer reservoir 24 that is maintained at a predetermined depth under the surface and above the collecting means. The submerged buffer reservoir 24 is in communication with the second, upper end 26 of the transfer tube 18 so as to receive the collected oil.
  • the collected oil is not directly channelled to the surface as is conventionally done, but is stored in the submerged buffer reservoir 24 at a given depth, e.g. 30 to 50 m below the sea surface.
  • the recovery of the leaking oil is thus not affected by weather conditions and particularly not affected by rough weather, which would otherwise hinder the oil recovery procedure.
  • the dome-shaped element 16 preferably is like an inverted funnel, i.e. its small opening is arranged above its large opening, so that it covers the wreck like an umbrella.
  • the inverted funnel 16 is anchored to the seabed around the wreck at several points, using anchoring means (described in detail below).
  • the bottom of the inverted funnel 16 is close to the wreck 12, e.g. about 20 m, so as to collect the escaping oil near to the source and thereby avoid oil shifting by water currents away from the collecting means 12.
  • the inverted funnel 16 should preferably be adapted to the size of the wreck 12, and may e.g. have a bottom as large as 50 m in diameter.
  • the inverted funnel 16 is provided with an opening 28, to which the lower end 20 of the transfer tube 18 is connected.
  • the transfer tube 18 is preferably vertically arranged above the apex of the inverted funnel 16, so that the collected oil, after converging toward the apex, will be led into the transfer tube 18 and rise therein, still under the effect of gravity and thus without the need of any additional energy.
  • the buffer reservoir 24 preferably has a central, cylindrical chamber 30 with an open-bottom and a bell-shaped outer hull.
  • the buffer reservoir is also advantageously designed so as to fulfil the function of terminal buoy, in order to control the tension on the transfer tube 18. This is achieved by the annular space 34 between the outer shell and the chamber 30 , which can thus serve as ballast reservoir for regulating the tension of the transfer tube, and shall also permit housing of auxiliary equipment therein if desired.
  • the transfer tube 18 penetrates into the chamber 30 through the open bottom so that its upper end 26 opens in the chamber 30.
  • the collected oil will thus exit the tube 18 and accumulate in the chamber 30, due to gravity, as represented in the drawing.
  • the channelled, leaked oil thus penetrates into the submerged buffer reservoir 24 through its open bottom in a very simple manner without being exposed to side water currents.
  • oil accum u-lates in the chamber 30 it replaces the initial sea water content out of the chamber 30, which is forced out through the open bottom.
  • the oil is separated from water, occupying the upper part of the submerged buffer reservoir.
  • the submerged buffer reservoir 24 not only acts as storage tank but also as separator.
  • the submerged buffer reservoir is advantageously provided in its upper part with a drainage port (not shown) for connection to e.g. a shuttle tanker 44 for emptying the chamber 30.
  • the drainage port may consist of standard equipment through which the shuttle tanker, weather permitting, can recuperate the stored oil rapidly, using standard off-shore loading equipment and methods, typically by pumping. The frequency of emptying operations will depend on the prevailing weather and currents and on the oil leaking rate.
  • the device 10 is normally kept in place until all the tanks of the wreck 12 are empty and the pollution threat eliminated. Once the device 10 is in place and collects the leaking oil without any problems, the whole operation can be accelerated simply by opening more holes at the tanks of the wreck.
  • the dimensions of the transfer tube 18 and the submerged buffer reservoir 24 typically depend on the maximum expected leak rate, the expected weather and sea current patterns.
  • the submerged buffer reservoir is preferably made of steel. It shall have a capacity of between 500 to 2000 t of oil, preferably between 1 000 and 1500 t. This would require a chamber having a volume of about 1500 m 3 .
  • the transfer tube 28 is advantageously externally provided with tensioning rings 40, distributed along its length and preferably regularly spaced (e.g. every 10 m).
  • the tensioning rings are preferably rigid in order to maintain the shape and cross-section of the transfer tube 28. Due to their buoyancy, the tensioning rings 40 allow controlling the tension of the transfer tube 28.
  • the tensioning rings 40 may all have the same buoyancy, but varying their buoyancy in function of their position along the transfer is a way to fine tune the tension of the tube 28 along its length.
  • the transfer tube 28 and the inverted funnel 16 may be made of fabric and preferably have close to neutral buoyancy for reasons of stability.
  • each anchor preferably include a plurality of suction anchors 36 distributed around the inverted funnel 16, each anchor being linked to the funnel by a respective cable 38 (normally steel cable).
  • a suction anchor is a standard anchoring means of the offshore industry, and typically consists in a big inverted bucket pushed deep into the ocean bed by pumping the water out.
  • the cables 38 also link the submerged buffer reservoir 24 to the anchors 36.
  • each cable 38 extends along the inverted funnel 16 and along the transfer tube 18, up to the bottom side of the buffer reservoir 24, to which it is solidly fixed.
  • the tensioning rings 40 also hold the cables 38 in place along the transfer tube 28, preventing thereby any entanglement during deployment and operation.
  • the number and dimensioning of cables 38 as well as the number, and buoyancy of the tensioning rings 40 allow for the regulation of not only the strength but also the rigidity (by pre-tensioning) of the transfer tube 18.
  • the terminal buoy 34 (buffer reservoir) also helps keeping the whole line in tension.
  • the cables may be clamped to the tensioning rings.
  • the device 10 can be anchored at as many additional points as necessary, using e.g. standard techniques and know-how of the offshore industry.
  • the prime factor for specifying the number and strength of the anchors 26, the transfer tube 28 and the cables 34 is the pattern of the expected sea currents and the resulting static and dynamically induced pull.
  • the fluid to be collected may have a high viscosity, which in conventional system often leads to wall sticking and/or clogging.
  • the transfer tube 18 of the present device When implemented to collect highly viscous fluids, such as oil, the transfer tube 18 of the present device preferably has a diameter of about 2 m. Such a diameter should allow to accommodate leaking flows of 1000 t of oil/water mix (e.g. 10% fluids - 90% water) daily without problems.
  • the flow through the transfer tube 28 can advantageously be enhanced by relatively simple means, e.g. by installing a heat source (not shown) in the vicinity of the connection between transfer tube 18 and funnel 16, so as to provoke a pumping effect by rising the pressure differential along the transfer tube.
  • Chemical agents can also be injected at the same point in order to reduce the viscosity and/or the specific weight of the fluid.
  • the inverted funnel 16 and transfer tube 18 are preferably made of a fabric to which adhesion is difficult, such as those commonly used in oil industry.
  • the use of fabric makes the device easily transportable and deployable, as the only solid part of the system is the storage buffer 24.
  • the cables 38 can e.g. be deployed synchronously, each one from its own drum, extending along the transfer tube 18 while the tensioning rings 40 would clamp the cables 38 at regular distances.
  • the transfer tube 18 could also be formed on the spot.
  • the device 10 is thus of simple and handy construction, and can be used for recovering a variety of fluids, in particular oil and chemical products. As has been explained above, the device is particularly well suited for recovering oil from foundered tankers and allows a prompt and cost effective intervention in case of catastrophes similar to the ERIKA or the PRESTIGE. In fact, it is of general applicability as long the pollutant does generally not dissolve and is of lower specific density than seawater.
  • the device 10 presents many significant advantages. Firstly, it is very si m-ple and does not require precise or elaborate manipulations or operations for its manufacturing or on-site deployment. Many of its components can be manufactured and assembled by non-specialised shipyards.
  • the transfer tube configuration can be implemented through a modular design, adding operational flexibility and lowering the cost.
  • the device can be operated entirely by non-specialised personnel. It is entirely passive: the flow of oil is gravity driven. If necessary, it can be enhanced by simple means (i.e. through a heat source or pumping means). Once in place, it does not require regular deep-sea operations or monitoring. The presence the submerged buffer reservoir makes the operations tolerant to the rough surface weather conditions.
  • the device is highly configurable, since both the transfer tube and the buffer reservoir can be optimised (anchoring parameters, tube and buffer reservoir dimensions, tube/wire tensioning, depth of the buffer reservoir, eventual intermediate buoys etc). Last but not least, due to its flexibility of operation the device can rapidly be installed in deep sea or shallower waters, and therefore can advantageously be a main tool in general intervention procedures to prevent major pollutions.
