The invention relates generally to an apparatus for containing, controlling and remediating pollutants floating on a surface of a body of water. In one embodiment, the pollutants may be present on the surface of the body of water as a result of an oil spill or other catastrophic event such as an explosion at an oil drilling facility.
The recent increased demand for fossil fuels, including crude oil, has also increased the danger to man and the environment resulting from oil exploration and shipment. In particular, the new technique for deepwater drilling (such as to depths of 40,000 feet) creates great temperature and pressure strain on equipment. The great depths and strain naturally cause failure and other catastrophic events which result in the accidental release of large amounts of oil into the environment with very harmful consequences. Therefore, a need exists for a device that will contain oil and other pollutants under these conditions.
In some aspects, the invention relates to a pollutant containment can 20, including a cylindrical shaped body with a hollow interior 24; a male end including a bulbous element 120; a female end 40 including an indented receiving element 130 adapted to connect with the bulbous element 120 of the male end 30 of a separate can 20; an internal baffle 60 located in the interior of the body; a float space 80 located in the interior of the body, where the volume of the float space is 1-60% of a total interior volume of the body; and multiple cable connectors 50 located on the exterior of the body for connecting the can 20 with other devices.
In other aspects, the invention relates to a pollutant containment device, including multiple pollutant containment cans 20 arranged in a circle, where each can 20 further includes a male end 30 which includes a bulbous element 120; a female end 40 including indented receiving element 130 adapted to connect with the bulbous element 120 of the male end 30 of a separate can 20, a plurality of float spaces 80 within the interior of the can 20, where the float space 80 is located proximate to the male end 30 and the female end 40 of the can 20, where a total volume of the float spaces is about twenty percent (20%) to percent fifty (50%) of a total volume of the can 20, three (3) internal baffles 60 located within the interior 24 of the can 20; and three (3) cable connectors 50 positioned on the exterior surface of the can 20, where the cable connectors 50 are oriented towards the interior of the circle, and a pollutant resistant fabric 160 located at a junction formed between the male end 30 of one can 20 and the female end 40 of another can 20; multiple connecting cables 180, that connect each can to at least two other cans 20 through the cable connectors 50; and an anchor 200.
Other aspects and advantages of the invention will be apparent from the following description and the appended claims.
To further advantages and features of the present disclosure, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. It is appreciated that these drawings are not to be considered limiting in scope.

A pollutant containment device 10 is provided herein. In one embodiment, the pollutant containment device 10 includes a plurality of cans 20 arranged in a circular pattern around a surfacing pollutant plume 220 or pollutant spill. As will be discussed in detail below, the pollutant containment device 10 of the present disclosure provides a more stable device for use in turbulent waters (such as the ocean during a severe weather event) wherein a first can 20 is free to rotate, bend and slightly separate or position itself slightly higher or lower than, without the use of a mechanical joint, relative to a second can 20 adjacent to the first can 20. The pollutant containment device 10 may also include a plurality of connecting cables 180 attached to all or some of the cans 20 in a deployed/assembled pollutant containment device 10. In one preferred embodiment, the can 20 is attached to three (3) connecting cables 180. In an alternate preferred embodiment, the cans 20 is attached to one (1) connecting cable.
In one embodiment, the pollutant containment device 10 is used to contain a hydrocarbon spill in the ocean. In one preferred embodiment, the hydrocarbon is an oil and in a most preferred embodiment, the oil is entering the ocean from a water well head or a leaking ocean going craft and is either rising to the ocean's surface 250 or is already on the ocean's surface 250. In one embodiment, a plurality of pollutant containment devices 10 may be used to contain a spill, the pollutant containment devices 10 being arranged in a serious of concentric circles around the site of a spill or surfacing pollutant plume 220. In an alternate embodiment, the pollutant containment device 10 may be deployed in a straight line to protect a bay, inlet or harbor.
Can 20
As shown in
One embodiment of the can 20 of the present disclosure is shown in
In one embodiment as shown in
As shown in
In one embodiment, the internal space 24 of the can 20 includes various support or other members. In one embodiment, the internal space 24 includes an internal baffle 60 as shown in
In one embodiment, the can 20 also includes an end plate 70 located in the inner space 34 wherein the end plate 70 partially defines a float space 80. The end plates 70 are similar in size and structure to the internal baffles 60, except that the end plates 70 are solid and are designed not to allow a substantial amount of water, or preferably any water, to pass through. In one embodiment, the end plate 70 is located proximate to the distal ends (the male end 30 and female end 40) of the can 20. In one embodiment, the can 20 includes a plurality of end plates 70 and in one preferred embodiment, the can 20 includes two (2) end plates 70.
The float space 80 is at least partially defined by the end plate 70 and the distal ends (the male end 30 and female end 40) of the can 20. The float space 80 is a substantially watertight space that is filled with air that provides a buoyant force acting on the distal ends of the can 20. In one embodiment, the float space 80 accounts for approximately between 1 to 60 percent of the total internal volume of the can 20. In a more preferred embodiment, the float space 80 accounts for approximately between 10 to 40 percent of the total internal volume of the can 20, in yet a more preferred embodiment, the float space 80 accounts for approximately embodiment, the float space 80 accounts for approximately 20 percent of the internal volume of a can 20.
In an alternate embodiment the can 20 includes an interior dividing wall that is located approximately along the can's 20 latitudinal centerline. This dividing wall essentially bisects the can 20 creating two (2) separate compartments. The separate compartments contain one or more interior baffles 60 as described above. In one embodiment, each separate compartment includes a floatation adjustment device 85 (described below) that functions to maintain the can's 20 position relative to the ocean's surface 250 and the other cans 20. In one embodiment, as needed the floatation adjustment device 85 can pump water into or out of the can 20 to maintain the can's position.
In some embodiments the can 20 also includes a floatation adjustment device 85 (not shown). In one embodiment, the floatation adjustment device 85 is a pump that is preferably sealed and designed to operate in a wet environment that can pump ballast sea water into or out of a can 20 as needed to adjust the can's 20 height in the ocean. For example, if a can 20 is positioned too low in the water (for example due to too much liquid being inside of the can 20) the pump could remove some of the liquid from inside of the can 20 thus raising the height of the can 20 and prevent any pollutant from overlapping the can 20 and escaping the pollutant containment device 10. In one embodiment, the pump is an electric pump that is sealed and specifically designed to operate in a wet environment. In one embodiment, the pump prevents water (or other liquid) from passing through when the pump is in the off position (or configuration). This prevents the cans 20 from becoming flooded and sinking or, vice versa, from can 20 from floating too high in the water if it is undesirable. The electricity for the electric pump be provided from many sources including a pollutant recovery vessel or a solar charger panel located on the can 20. In one embodiment, the electricity for the pump (and the controls for the pump may be housed in a specially designed command can (not shown), wherein the command can is adapted to provide access to the controls and pump for maintenance. Other pumps and methods of implementing the pumps are well known to those of ordinary skill in the art.
In yet another embodiment, the can 20 may include a bladder (not shown) and a source of compressed gas (not shown) either within the internal space 24 or attached to the outside of the can 20. These items may be used in the event of a hurricane or other severe weather event as described herein. If a hurricane or other severe weather event is approaching the location of an assembled/deployed pollutant containment device 10, the flotation adjustment device 85 may be used to “flood” the cans 20 causing them to “sink” below the water's surface, hopefully reaching a level below the water's surface where the pollutant containment device 10 could survive or “ride out” the event. After the event has passed, the bladder could be inflated with the compressed gas and cause the pollutant containment device 10 to rise to the water's surface and resume normal function.
As shown in
As shown in
In one embodiment, the cans 20 and the male end 30 and the female ends 40 are essentially in a straight line. In an alternate embodiment (not shown), especially useful in a circle with a tight radius, the can 20 may be bent (or arced slightly) to facilitate making the circular pollutant containment device 10, in yet another embodiment, the male end 30 or female end 40 may be bent or arced to facilitate making the circular pollutant containment device 10.
In one embodiment, the male end 30 and the female end 40 may be covered with a durable coating 90 to protect the cans 20 and the male end 30 and female end 40 from impact trauma. As will be recognized by one of ordinary skill in the art, as adjacent cans move (in all three axes) it is possible that they will come in contact with one another. The durable coating 90 provides protection from these traumatic impact forces. In one embodiment, the durable coating 90 is a hard rubber compound. In other embodiments, the male end 30 and the female end 40 may have an inflated bladder present to protect them from traumatic impact forces.
In an alternate embodiment, the male end 30 and female end 40 are manufactured from a durable piece of material that can function to absorb (or lessen) the impact trauma acting upon the cans 20 caused by the movement of the ocean waves. In one embodiment, this durable piece of material is a hard rubber or other vulcanized material. Other materials known to those of skill in the art should be considered within the scope of this disclosure.
In one preferred embodiment, the can 20 includes a female end 40 and a male end 30 and the can 20 is approximately fifty (50) feet long and has a diameter of 12 feet. In this embodiment, the can 20 also includes three (3) cable connectors spaced as follows: a first cable connector 50 located at the midpoint of the can 20, a second cable connector 50 located approximately sixteen and ⅓ feet from the first cable connector 50 towards the female end 40 of the can 20 and a third cable connector 50 located approximately sixteen and ⅓ feet from the second cable connector towards the male end 30 of the can 20. In this embodiment, the can 20 also includes three (3) internal baffles 60 located in the internal space 24 opposite the cable connectors 50. Finally, in this preferred embodiment, the can 20 includes two (2) end plates located approximately 10 feet from the distal ends of the can 20 and the float space 80 is approximately twenty percent (20%) of the total volume of the can 20.
Junction
The pollutant containment device 10 includes a plurality of cans 20 connected by a junction between a first can and second can, as shown in
After the bulbous clement 120 is inserted into the receiving element 130, the second can will retain some degree of rotational freedom relative to the first can due, at least in part, to the fact that the receiving element 130 is slightly larger than the bulbous element 120. This degree of rotational freedom allows the pollutant containment device 10 to float on and respond to the motion of waves and other forces on the water's surface without compromising either the structural or operational integrity of the pollutant contaminant device. In one embodiment, as ocean waves fall and crest the first can and the second can rotate or move in all three (3) axes with the waves.
In one embodiment, the junction between the first can and the second can also includes either a pollutant resistant fabric 160 or a woven material 170, or both. In one embodiment, the pollutant resistant fabric 160 and the woven material 170 can be a single material while in other embodiments the woven material 170 is separate and distinct from the pollutant resistant fabric 160. In one embodiment, the pollution resistant fabric 160 needs to be either “loose” when fitted over the junction or “stretchable” to allow the junction to flex or move as detailed herein.
In one embodiment, the pollutant resistant fabric 160 is positioned so that it covers the first surface (as defined above) of the junction, or only 180 degrees of the junction. Generally, the pollutant resistant fabric 160 is positioned so that the pollutant that needs containing or remediating cannot “seep through” or otherwise pass through the junction. In another embodiment, the pollutant resistant fabric 160 is positioned around the entire (or 360 degrees) of the junction. In one embodiment, the pollutant resistant fabric 160 is impermeable to the pollutant to be contained and remediated. As would be recognized by one skilled in the art, the material comprising the pollutant resistant fabric 160 may be selected based upon the pollutant to be contained and remediated.
The pollutant resistant fabric 160 may be held in place by a first band 100 which functions to secure the pollutant resistant fabric 160 in place. In one embodiment the pollutant resistant fabric. 160 may be held in place by an o-ring or other suitable structure as would be recognized by one skilled in the art.
In one embodiment, the junction between the first can 20 and the second can 20 also includes a woven material 170. This woven material 170 functions to keep the first can 20 and the second can 20 from completely separating. In one embodiment, the woven material 170 is cloth or fabric and is a cylindrical, helically wound braid such as a biaxial braid. Pulling the entire braid lengthens and narrows it. The length is gained by reducing the angle between the warp and weft threads at their crossing points, but this reduces the radial distance between opposing sides and hence the overall circumference. The more one pulls, the more the circumference shrinks (i.e., tightens). In one embodiment, the woven material 170 is a woven stainless steel or other corrosion resistant metal. In yet another embodiment, the woven material 170 is woven nylon. However, it should be understood that any suitable material known in the art could be used.
In an alternate embodiment, as shown by
In yet an alternate embodiment (not shown), the male ends 30 do not contain the bulbous element 120 but rather contain a flat (or essentially flat) surface that may be in contact with an adjacent male end 30.
