Definitions
- This invention is a system and method for repairing and reconfiguring an oil containment boom, using end connectors and attached curtain members in various arrangements to form outer booms, inner booms, extending booms, and transverse booms for added safety and protection and for an enhanced ability to contain, collect, and recover spilled oil contaminates.
- Oil spills can be both devastating and disastrous to ecological and marine environments, and can also affect physical resources, as well as a wide range of organisms that are linked in a complex food chain. This food chain also includes human food resources that are essential.
- Oil spills can harm living things because its chemical constituents are poisonous.
- Various types of freshwater and marine habitats that exist in nature have different sensitivities to the harmful effects of oil contamination, as well as different abilities to recuperate. Although some organisms may be seriously injured or killed very soon after contact with the oil in a spill, other effects are subtler and may often be longer lasting. For example, freshwater organisms are at risk of being smothered by oil that is carried by the current, or of being slowly poisoned by long-term exposure to oil trapped in shallow water or stream beds. In addition, oil can potentially have catastrophic effects on birds and mammals.
- Oil spills can happen in open seas, as well in navigable waterways. Damage to even a moderate sized oil tanker can result in the leakage of thousands of barrels of oil into the waters around the tanker. A blow-out in an off-shore oil rig can also result in disastrous damage to the environment, as well as the economy. Moreover, when such oil spills occur close to a shoreline, the danger of damaging fragile environmental ecosystems is considerably higher.
- One method for controlling the damage of an oil spill is with the use of oil-containment systems, where inflatable “booms” surround the spill until the oil can be collected.
- Boom systems prevent the spill from expanding or reaching a protected area, such as a shoreline, until it can be collected by mechanical means.
- a typical boom system employs a plurality of boom sections joined end to end.
- Each boom section includes a plurality of parallel inflatable chambers that are joined with a weighted curtain, and the boom sections are connected by a cable on top and by a weight member (such as a chain) on the bottom.
- a weight member such as a chain
- boom systems To help detect damaged booms, environmental protection agencies require that boom systems be regularly inspected. Thus, if a breach occurs, the boom must be repaired on site. Furthermore, some repairs require removal of an entire boom section, which can span over 100 ft in length. Ideally, once a boom section is removed, another boom section is brought in to replace it. However, the time needed to remove and replace a boom section of such an enormous length can take hours. Further, once the damaged boom section is removed, contaminated water will again be able to flow freely upon the shoreline. As indicated above, such a free flow of contaminated water could be disastrous, as miles of shoreline and wildlife would again be at risk.
- This invention provides a system and method for repairing and reconfiguring an oil containment boom, using end connectors and attached curtain members in various arrangements to form outer booms, inner booms, extending booms, and transverse booms for added safety and protection and for an enhanced ability to contain, collect, and recover spilled oil contaminates.

- An apparatus for boom repair includes at least one end connector and a curtain attached to the end connector.
- the curtain is attached between two end connectors.
- the end connectors are also used to attach the curtain to a damaged, existing boom via an opening slot in the connector.
- the system for repairing of replacing an existing boom includes forming a tight seal between the curtain and existing boom.
- the method for reinforcing a boom includes connecting one end of a curtain to an existing boom, and connecting another end of the same curtain to the same, existing boom. Both connections are secured in place by sliding the end connectors over the existing boom at separate areas that covers the damaged section of the existing boom. Next, the end connectors are locked in place via a lock-pin mechanism. This locking creates a tight seal over the damaged area, creating a “patch” to keep out oil contaminants from the protected area.
- the disclosed invention can accordingly be used to repair, patch, or reinforce an existing oil containment boom.
- FIG. 1 illustrates a marsh environment 102 located along a shoreline that would require protection from contaminated waters 104 .
- the existing boom 108 is attempting to provide protection of the marsh environment 102 .
- the existing boom 108 includes one or more floatation members 110 to provide buoyancy in the water.
- the existing boom 108 also includes a weighted member, such as a chain 112 to connect a boom section 113 to other boom sections or to end anchors 114 .
- the chain 112 also serves the purpose of weighing down the curtain 116 area of the existing boom.
- Anchor points can be created every 50 ft along the length of the existing boom 108 by attaching anchors 114 to the chain 112 in spaced intervals.
- Boom sections 113 can typically be about 100 ft long in length.
- booms 108 can remain in waters for long periods of time, there are incidents where booms 108 become damaged, as illustrated by the damaged area 118 .
- the damaged area 118 can be created or caused by a variety of factors. Also, there can be a number of problems that would be classified as damage. For example, a boom can become torn, which may be caused by random objects in the water, by strong water currents, or so forth. Another common failure that could create a damage area 118 is an excess of contaminated matter that had saturated the boom. A saturated boom losses buoyancy and can begin to sink, and thus a boom damaged due to saturation will not provide the proper protection needed from contaminated waters 104 . Further, a damaged area 118 on a boom can allow contaminated waters 104 to reach the marsh environment 102 and shoreline, causing considerable damage to the vegetation and wild life.
- FIG. 2 illustrates an oil boom repair system 201 attached to an existing boom 202 affected by a damage area 203 .
- the existing boom 202 includes a plurality of buoyant floatation members 204 to provide buoyancy in the water.

- the curtain member 210 is formed from liquid-impermeable materials, such as vinyl. Alternatively, the curtain 210 can be made of any flexible material with relatively high tensile strength and sheer strength that is liquid-impermeable.
- the end connectors 208 are designed and built with a 45-degree plane that helps the curtain 210 of the oil boom repair system 201 to create a tight seal 205 upon the damage area 203 of the existing boom 202 .
- the damage area 203 is shown as a tear in the boom.
- the oil boom repair system 201 can be used to repair other types of damages that would occur. In fact, the oil boom repair system 201 is able to reinforce an existing boom 202 as needed.
- wind and water currents which may have initially caused the damage area 203 , can now be used to help secure placement of the oil boom repair system 201 , as well as help form a tight seal 205 of the curtain 210 of the oil boom repair system 201 upon the existing boom 202 .
- Additional support is also provided via the extra set of weighted chains 211 of the oil boom repair system 201 .

- the opening slot 404 is closed and secured by the lock-and-pin mechanism.
- different embodiments can utilize various locking mechanisms.
- the end connector 208 can be secured and locked into place via a hitch pin (or any variation).
- a hitch pin or any variation.
- These are simple forms of hardware used to temporarily mount or conjoin mating components. Virtually any type of pin requires at least one predrilled hole that is meant to hold and retain the end connector 208 with two mating segments are aligned and then held in position by the pin 604 .
- a 6-inch chain 605 connects the pin 604 to the rigid locking bar member 407 .
- Other embodiments can utilize a different chain length, as needed.
- a hitch pin (as well as a clevis pin) requires an additional cotter pin inserted perpendicularly to lock the pin in position.
- lynch pins, detent pins, snapper pins, safety spring pins, and toggle pins all contain integral locking mechanisms. Like other pins, these mechanisms are meant to resist shear forces, which make them fundamentally different than bolts and screws. These mechanisms may be used as shear pins in mechanical overload situations.
- the oil boom repair system can be applied to existing booms that are already deployed in the open waters.
- the quick application makes it efficient, and avoids exposing shoreline to oil contaminants.
- the quick application also makes it less difficult to deploy during bad weather and stormy seas.
- the oil boom repair system of the present invention makes it easier to improve techniques used to clean up an oil spill, thus cutting down response time.
- This efficient application contributes to the protection of various environments, including open seas, coastal waters, and wetlands. Pollution-control measures, such as containment and removal of the oil (by skimming, filtering, and so forth), are improved with use and availability of the oil boom repair system.
- Oil spill countermeasures to clean up and remove the oil are selected and applied based on many interrelated factors, including ecological protection, socioeconomic effects, and health risk. It is important to have contingency plans in place in order to deploy pollution control personnel and equipment efficiently. The rate of recovery of the environment when an oil spill occurs depends on factors such as oil composition and resource availability. The presented embodiments herein greatly improve the resources available for oil spill clean-up and containment.
- the oil boom repair system for boom repair includes two mirror image end connectors with a portion fabricated at 45-degrees from the plane surface of the other portion.
- the flexible liquid-impermeable curtain member is attached between the two rigid end connectors.
- the end connectors are also used to attach the oil boom repair system to a damaged, existing boom via the end connector's opening slot.
- This presented disclosure is used for repairing of reinforcing an existing boom by forming a tight seal between the curtain and existing boom with the use of the angled end connectors.
- Another embodiment presented introduced a suitable application method.
- This embodiment includes connecting one end connector of the instant oil boom repair system to an existing boom and engaging it to an existing boom connector.
- the second end connector is engaged with the boom on the other side of the damaged section so that the damaged area is covered by the extension of the curtain member, whereby the damaged section become isolated and sealed from the contaminated water.
- Both connections are attached by sliding the connectors over the existing boom.
- the connectors are locked into place via a lock-pin mechanism.
- This embodiment also creates a tight seal over the damaged area, creating a “patch” to keep out oil contaminants from the protected area.
- the disclosed invention can be used to repair, patch, or reinforce an existing boom that could subject to the problems such as tears, saturation, or other damage.
- Another set of embodiments are used to reconfigure and extend existing oil booms 202 so that they can be used more effectively and more safely.
- a pair of end connectors 208 with a curtain member attached can function as an outer boom which protects a temporary opening made in a segment of the oil containment boom.
- Such an outer boom is needed in circumstances when, for example, a rookery area is protected by an oil containment boom, but where biologists or others need access to the rookery to examine or clean the birds. It would be dangerous to just uncouple the oil boom to create a temporary opening. The contamination on one side of the boom might be sufficient to flow through such an opening, and changing winds, waves, and weather might drive contamination through.
- the end connectors 208 are placed on either side of the intended temporary opening, with a curtain member 210 of sufficient length to encompass a boat, forming an outer boom. After the outer boom is put in place, the existing oil boom 202 can be safely uncoupled to form a temporary opening.
- an opening and closing gateway can be formed between two sections of existing boom 202 running very roughly parallel to each other by placing an end connector 208 on each existing boom 202 , with each end connector attached to an end of a curtain member 210 , where that curtain member has a standard butt joint which can be uncoupled to allow the curtain member to be used as an opening and closing gate.
- the illustrated embodiment uses two such gates separated by a significant expanse of water. The two gates provide a fail-safe closure, and the expanse of water between provides both a buffer against any oil that might breach the outer gate, and a decontamination area where any oil that might be clinging to the hull of a boat might be washed away.
- an inner boom can be placed across a portion of the existing boom 202 .
- An embodiment of the invention can be used to form an extension boom extending generally perpendicularly from the existing boom 202 .
- An end connector 208 is attached to the existing boom 202
- a length of curtain member 210 is attached to the end connector 208 .
- the other end of the curtain member 210 can be left free and can be anchored to maintain the extension boom in a useful position.
- transverse extension booms that do not extend across the entire channel.
- Each transverse boom will collect some oil until the amount of collected oil reaches a maximum and spills over the free end of the transverse boom.
- a series of such transverse booms can form a cascade, collecting a significant amount of oil.
- the free ends of the curtain members 210 forming the transverse booms can be anchored in place to maintain proper placement.
- an end connector 208 is attached to an existing oil boom 202 across a channel of flowing water so as to form a chevron or angled boom, which forces oil contaminates toward the sides or shores. In most circumstances, it will be desirable to anchor the end connector 208 in order to preserve the chevron form.

No. 9,551,124 on Jan. 24, 2017, which is a continuation of my application Ser. No. 14/564,757 for a “Patch System and Method for Oil Boom,” filed Dec. 9, 2014 and issued as U.S. Pat. No. 9,410,301 on Aug. 9, 2016, the full disclosures of which are hereby incorporated by reference.
- This invention is a system and method for repairing and reconfiguring an oil containment boom, using end connectors and attached curtain members in various arrangements to form outer booms, inner booms, extending booms, and transverse booms for added safety and protection and for an enhanced ability to contain, collect, and recover spilled oil contaminates.
- Due to an increase in oil production and oil transportation, there is an increase in accidental oil spills. Oil spills can be both devastating and disastrous to ecological and marine environments, and can also affect physical resources, as well as a wide range of organisms that are linked in a complex food chain. This food chain also includes human food resources that are essential.
- Oil spills can harm living things because its chemical constituents are poisonous. Various types of freshwater and marine habitats that exist in nature have different sensitivities to the harmful effects of oil contamination, as well as different abilities to recuperate. Although some organisms may be seriously injured or killed very soon after contact with the oil in a spill, other effects are subtler and may often be longer lasting. For example, freshwater organisms are at risk of being smothered by oil that is carried by the current, or of being slowly poisoned by long-term exposure to oil trapped in shallow water or stream beds. In addition, oil can potentially have catastrophic effects on birds and mammals.
- Oil spills can happen in open seas, as well in navigable waterways. Damage to even a moderate sized oil tanker can result in the leakage of thousands of barrels of oil into the waters around the tanker. A blow-out in an off-shore oil rig can also result in disastrous damage to the environment, as well as the economy. Moreover, when such oil spills occur close to a shoreline, the danger of damaging fragile environmental ecosystems is considerably higher.
- One method for controlling the damage of an oil spill is with the use of oil-containment systems, where inflatable “booms” surround the spill until the oil can be collected. Boom systems prevent the spill from expanding or reaching a protected area, such as a shoreline, until it can be collected by mechanical means.
- A typical boom system employs a plurality of boom sections joined end to end. Each boom section includes a plurality of parallel inflatable chambers that are joined with a weighted curtain, and the boom sections are connected by a cable on top and by a weight member (such as a chain) on the bottom. However, because boom systems can remain in water for long periods of time, there are incidents where boom sections become damaged. This damage can either be caused by objects in the water, or by strong water currents. A damaged boom can be just as disastrous as the original oil spill itself; for example, a tear in a boom can no longer contain the oil, nor can it prevent oil from reaching a shoreline.
- To help detect damaged booms, environmental protection agencies require that boom systems be regularly inspected. Thus, if a breach occurs, the boom must be repaired on site. Furthermore, some repairs require removal of an entire boom section, which can span over 100 ft in length. Ideally, once a boom section is removed, another boom section is brought in to replace it. However, the time needed to remove and replace a boom section of such an enormous length can take hours. Further, once the damaged boom section is removed, contaminated water will again be able to flow freely upon the shoreline. As indicated above, such a free flow of contaminated water could be disastrous, as miles of shoreline and wildlife would again be at risk.
- This invention provides a system and method for repairing and reconfiguring an oil containment boom, using end connectors and attached curtain members in various arrangements to form outer booms, inner booms, extending booms, and transverse booms for added safety and protection and for an enhanced ability to contain, collect, and recover spilled oil contaminates.

FIG. 14 illustrates the use of the oil-boom repair and reconfiguration system to form a chevron shape in an oil boom. - The problems and issues identified in the above Background are at least partly addressed by the apparatus, system, and methods disclosed herein. An apparatus for boom repair includes at least one end connector and a curtain attached to the end connector. The curtain is attached between two end connectors. The end connectors are also used to attach the curtain to a damaged, existing boom via an opening slot in the connector. The system for repairing of replacing an existing boom includes forming a tight seal between the curtain and existing boom.
- The method for reinforcing a boom includes connecting one end of a curtain to an existing boom, and connecting another end of the same curtain to the same, existing boom. Both connections are secured in place by sliding the end connectors over the existing boom at separate areas that covers the damaged section of the existing boom. Next, the end connectors are locked in place via a lock-pin mechanism. This locking creates a tight seal over the damaged area, creating a “patch” to keep out oil contaminants from the protected area. The disclosed invention can accordingly be used to repair, patch, or reinforce an existing oil containment boom.
- The disclosed apparatus, system, and methods are best understood in a suitable usage context. Accordingly,
FIG. 1 illustrates amarsh environment 102 located along a shoreline that would require protection from contaminatedwaters 104. The existingboom 108 is attempting to provide protection of themarsh environment 102. The existingboom 108 includes one ormore floatation members 110 to provide buoyancy in the water. The existingboom 108 also includes a weighted member, such as achain 112 to connect aboom section 113 to other boom sections or to endanchors 114. Thechain 112 also serves the purpose of weighing down thecurtain 116 area of the existing boom. Anchor points can be created every 50 ft along the length of the existingboom 108 by attachinganchors 114 to thechain 112 in spaced intervals.Boom sections 113 can typically be about 100 ft long in length. - Because
booms 108 can remain in waters for long periods of time, there are incidents wherebooms 108 become damaged, as illustrated by the damagedarea 118. The damagedarea 118 can be created or caused by a variety of factors. Also, there can be a number of problems that would be classified as damage. For example, a boom can become torn, which may be caused by random objects in the water, by strong water currents, or so forth. Another common failure that could create adamage area 118 is an excess of contaminated matter that had saturated the boom. A saturated boom losses buoyancy and can begin to sink, and thus a boom damaged due to saturation will not provide the proper protection needed from contaminatedwaters 104. Further, a damagedarea 118 on a boom can allow contaminatedwaters 104 to reach themarsh environment 102 and shoreline, causing considerable damage to the vegetation and wild life. - Conventional repairs normally require removal of an entire
damaged boom section 113, which could be about 100 ft in length. The replacement of an entiredamaged boom section 113 could take hours to complete. During replacement of theboom section 113, contaminatedwaters 104 will be able to flow freely toward themarsh environment 102 and shoreline. Substantial damage may additionally occur to themarsh environment 102 by the contaminatedwaters 104 during replacement of theentire boom section 113. The present invention is accordingly constructed to serve as a repair or “patch” system to the damagedarea 118 of the existingboom 108, thus providing protection of themarsh environment 102 and shoreline from contaminatedwaters 104. -
FIG. 2 illustrates an oilboom repair system 201 attached to an existingboom 202 affected by adamage area 203. The existingboom 202 includes a plurality ofbuoyant floatation members 204 to provide buoyancy in the water. The existingboom 202 also includes a weighted member, such as achain 206, that connects adjacent boom sections to each other. The oilboom repair system 201 is attached to the existingboom 202 byend connectors 208. The oilboom repair system 201 includes acurtain member 210 that is also weighed down bychains 211. Thecurtain 210 also includes aflotation member 213 in its top portion. Thefloatation member 213 is sealed inside the curtain member. In the preferred embodiment, the floatation member can be of cylindrical configuration and formed from closed cell foam. Thecurtain member 210 is part of the oilboom repair system 201, and is securely attached to theend connectors 208. The end connectors are locked in place by the rigid locking bars 215. Thecurtain member 210 is formed from liquid-impermeable materials, such as vinyl. Alternatively, thecurtain 210 can be made of any flexible material with relatively high tensile strength and sheer strength that is liquid-impermeable. - In the preferred embodiment, the
end connectors 208 are designed and built with a 45-degree plane that helps thecurtain 210 of the oilboom repair system 201 to create atight seal 205 upon thedamage area 203 of the existingboom 202. In the embodiment shown inFIG. 2 , thedamage area 203 is shown as a tear in the boom. However, it should be noted that the oilboom repair system 201 can be used to repair other types of damages that would occur. In fact, the oilboom repair system 201 is able to reinforce an existingboom 202 as needed. Moreover, wind and water currents, which may have initially caused thedamage area 203, can now be used to help secure placement of the oilboom repair system 201, as well as help form atight seal 205 of thecurtain 210 of the oilboom repair system 201 upon the existingboom 202. Additional support is also provided via the extra set ofweighted chains 211 of the oilboom repair system 201. Preferred embodiments of the present disclosure can be added over a small area of an existing boom or to a large area over hundreds of feet in length. -
FIG. 3 is a closer view of the oilboom repair system 201, which includes a pair of mirrorimage end connectors 208 supporting acurtain member 210. Thecurtain member 210 includes a top portion with one ormore flotation members 213 secured thereto. The top portion is provided with a small opening for acable 217 to run through, and abottom portion 220 supporting aweighted chain 211. Thecurtain member 210 can be made of vinyl material, which will help block oil, trash, and debris in contaminated waters. If properly maintained, the durable oil boom repair system may provide years of service to oil boom sections. - In the preferred embodiment, the
curtain member 210 hangs below the surface of the water at a little over twelve inches to keep pollutants from creeping under the spill containment boom section. The flotation member(s) 213 in the top area keeps the oilboom repair system 201 float at the water line, and thelower portion 220 is used to support the weighted ballast, such aschain 211 that exerts a downward force on thecurtain member 210 below the surface of the water. In one aspect of the invention, the oilboom repair system 201 utilizes a galvanizedsteel chain 211 to run through the length of thecurtain member 210, thus adding weight and additional rigidity to the boom. - The floatation member(s) 213 is sealed inside the curtain. In one of the embodiments, each floatation member is shaped as a cylinder and formed of closed cell foam. The
curtain member 210 has sufficient longitudinal and vertical dimensions to cover the damaged section when stretched between the first end connector and the second end connector that have been engaged with the boom. Although different colors could be used, one of the embodiments of the oilboom repair system 201 may have ayellow curtain member 210, so that the oilboom repair system 201 system can be easily located in any weather. - Conveniently, the oil
boom repair system 201 can be designed at any length to suit the needs of the damaged area of the existing boom. The adjustable length can be obtained through the use of conventional,universal slide connectors 315.FIG. 3 shows the use of theseuniversal slide connectors 315 at the center of thecurtain member 210, as well as at the ends of the curtain member between thecurtain member 210 and theend connector 208. Theuniversal slide connectors 315 can be made from marine-grade aluminum, and are constructed to hold hydrocarbons or debris from getting through in the areas where boom sections are connected. The oilboom repair system 201 can be deployed by operators 317 by having the operators 317 attach it to the existing oil containment booms from a floating vessel or stationary docks within minutes. The oilboom repair system 201 can be used in marinas, inland waterways, and in harbors. -
FIGS. 4A and 4B show theend connector 208 in more detail. In particular,FIG. 4A illustrates a side view, andFIG. 4B shows a top view of the end connector of the oilboom repair system 201. As can be seen in the drawings, theend connector 208 comprises a pair of integrally unitary connected elongatedplanar portions first portion 402 is inclined in relation to anormal plane 403 of thesecond portion 406; the angle of inclination designated as “a” inFIG. 4B can be 45-degrees. This 45-degree angle on the end connector helps to provide a tight curtain-to-curtain seal and attachment of the oil boom repair system to an existing boom. However, other embodiments or variations may use a different angle. Wind and water currents also facilitate secure placement of the oil boom repair system, as well as help in forming a tight seal of the curtains of the oil boom repair system and of the existing boom. - In one of the exemplary embodiments, each
end connectors 208 is about 30 inches in height, 10 inches in length, and 1 inch in width. Eachend connector 208 can be made of marine grade aluminum. - A T-shaped
slot 404 is formed in thesecond portion 406. Theslot 404 extends from a bottom edge 405 a distance upwardly along the height of theend connector portion 406. Afirst part 409 of theslot 404 extends longitudinally upwardly from thebottom edge 405, and a boom-receivingopening 408 is defined by the bottom of theslot 404. Thefirst part 409 of theslot 404 can be about 0.5-inches in width. - A
second part 410 of theslot 404 is formed transversely to the longitudinal part 409 a distance from anupper edge 412 of the body. Thesecond part 410 has sufficient width to allow an operator 317 to grasp theend connector 208 when positioning or removing theend connector 208 from the oil containment boom. In one exemplary embodiment, thetransverse part 410 of theslot 404 can be 3.5 inches in length to allow easy handling of theend connector 208. - A
rigid locking bar 407 is pivotally secured to a lower part of the portion 406 a distance from theelongated slot 404. This lockingbar 407 is used for locking and securing theend connector 208 to an existing boom by securing therigid locking bar 407 to bottom of theend connector portion 406 to close theslot opening 408 via a lock-pin mechanism after theend connector 208 has been positioned on the damaged oil containment boom. -
FIGS. 5A and 5B illustrate methods of attachment of the oil boom repairsystem end connector 208 to an existingboom 202. As shown, the attachment of the oil boom repairsystem end connector 208 to an existingboom 202 is relatively simple and can be completed in minutes. Anoperator 505 slides theend connector 208 of the oil boom repair system over the existingboom 202 using theslot 404. The existing boom 202 (although damaged or saturated) has acurtain 116 andweighted chain 206, as shown inFIG. 5A . The method for repairing or reinforcing a boom includes connecting oneend connector 208 and a second mirror image end connector to the existingboom 202 on another side of the damaged area of theboom 202. Next, the installation method includes locking theend connectors 208 in place via a lock-and-pin mechanism 407 by anoperator 505, as shown inFIG. 5B . The lock and pin mechanism secures the oil boom repair system in place, and allows the repair to withstand strong wind and water currents. -
FIG. 6 illustrates the compatibility of the end connectors with auniversal boom connector 601. Under this embodiment, theoperator 603 simply slides theend connector 208 into theuniversal boom connector 601 and secures it in place. This feature of the invention makes it easy and suitable for other users in the oil boom containment industry. Thecurtain member 210 of the oil boom repair system includes and is already sewn or securely clamped onto auniversal boom connector 601, similar to a typical, existing boom section. Next, theuniversal boom connector 601 slides onto theend connector 208. Typical connectors can be provided with the various jaw configurations by mating two connectors together. Typical connector/jaw configurations are defined by the American Society for Testing and Materials (ASTM) and also by industrial configurations. The present embodiment is compatible withconnectors 601 that include two flat plates bolted through a fabric member, wherein a connecting jaw or other connecting interface is utilized to mate two connectors at the junction of the two boom sections. The present embodiment supplies a good connection that is secure and strong, and accordingly prevents oil leaks. The connection between the oil boom repairsystem end connector 208 and theuniversal connector 601 is important, because common failure of the oil boom is often at the connector. - The oil boom repair system's
compatible end connector 208 is also constructed to be easy to manipulate. This is particularly important because rough weather make connections very difficult to maintain. In the preferred embodiment, the oil boom repairsystem end connector 208 is compatible with typical oil boom connectors that are extruded from aluminum alloy, and fabricated to standard oil boom connector lengths (12-inch, 18-inch, 24-inch or 36-inch lengths). The oil boom repairsystem end connector 208 is fabricated to connect with standard bolt-hole pattern plates. The present embodiment is compatible withstandard industry connectors 601, which may be either male or female. The oil boom repairsystem end connector 208 is also designed to meet typical ASTM standards, and is designed to be compatible with other connection profiles, including “Z” connectors and light duty mini-slide connectors. -
FIG. 6 also illustrates thepin 604 andchain 605 of the locking mechanism for securing the oil boom repairsystem end connector 208 to an existing boom. Thepin 604 andchain 605 are linked to a pivotal,rigid locking bar 407 that rotates to open and close the T-shapedslot 404 of theend connector 208. Therigid locking bar 407 is pivotally secured to a lower part of the second planar portion 406 a distance from the elongated slot. The lockingbar 407 pivots about apivot pin 609, which extends through the locking bar and is secured to theend connector portion 406. The lockingbar 407 carries a flexible securing member, forinstance chain 605, suspended from the lockingbar 407 and configured for free pivotal movement about thepivot pin 609. As shown inFIG. 6 , a free end of the securing chain carries alocking pin 604. Anaperture 610 is formed in the locking bar 407 a distance from thepivot pin 609, and acorresponding opening 611 is formed in the second planar portion of the rigid body of theend connector 208. Thelocking pin 604 is configured for engagement within theaperture 610 of the locking bar 606 and theopening 611 insecond portion 406 when the lockingbar 407 is pivoted to align theaperture 610 and theopening 611. The lockingbar 407 detachably secures the boom repair member on the portion of the oil containment boom, while preventing disengagement of the end connectors from the oil containment boom. When engaged with the boom, the locking bar extends under the boom. - In alternative embodiments, the attachment or connecting portion of the present invention is made of a material having endurance and strength with respect to a mechanical load such as bending, tensile, compression, and kink, taking use in sea or waterways into consideration. It is desired that the entire oil boom repair system (including the end connectors) has lightweight materials, except the bottom portion of the curtain.
-
FIG. 7 illustrates a lockedend connector 208. Theend connector 702 can be fabricated as any type of lightweight non-corrosive material, such as marine-grade aluminum. The T-shapedslot 404 allows for easy manipulation and installation by an operator. Theslot 404 also allows for a top cable to pivot, and not bind up. In this illustration, bolt-receivingopenings 450 can be seen spaced along avertical edge 452 of thefirst portion 402. Theopenings 450 are designed to match spaced openings on theuniversal boom connector 601, as described above. - The elongated member or locking
bar 407 closes theopening slot 404 of theend connector 208 after it is placed upon an existing boom. Theopening slot 404 is closed and secured by the lock-and-pin mechanism. In the present invention, different embodiments can utilize various locking mechanisms. For example, theend connector 208 can be secured and locked into place via a hitch pin (or any variation). These are simple forms of hardware used to temporarily mount or conjoin mating components. Virtually any type of pin requires at least one predrilled hole that is meant to hold and retain theend connector 208 with two mating segments are aligned and then held in position by thepin 604. In order to help prevent the loss of thepin 604, a 6-inch chain 605 connects thepin 604 to the rigidlocking bar member 407. Other embodiments can utilize a different chain length, as needed. - In one embodiment, a hitch pin (as well as a clevis pin) requires an additional cotter pin inserted perpendicularly to lock the pin in position. In other embodiments, lynch pins, detent pins, snapper pins, safety spring pins, and toggle pins all contain integral locking mechanisms. Like other pins, these mechanisms are meant to resist shear forces, which make them fundamentally different than bolts and screws. These mechanisms may be used as shear pins in mechanical overload situations.
- As discussed via the presented embodiments, the oil boom repair system can be applied to existing booms that are already deployed in the open waters. The quick application makes it efficient, and avoids exposing shoreline to oil contaminants. The quick application also makes it less difficult to deploy during bad weather and stormy seas. Further, the oil boom repair system of the present invention makes it easier to improve techniques used to clean up an oil spill, thus cutting down response time. This efficient application contributes to the protection of various environments, including open seas, coastal waters, and wetlands. Pollution-control measures, such as containment and removal of the oil (by skimming, filtering, and so forth), are improved with use and availability of the oil boom repair system.
- Oil spill countermeasures to clean up and remove the oil are selected and applied based on many interrelated factors, including ecological protection, socioeconomic effects, and health risk. It is important to have contingency plans in place in order to deploy pollution control personnel and equipment efficiently. The rate of recovery of the environment when an oil spill occurs depends on factors such as oil composition and resource availability. The presented embodiments herein greatly improve the resources available for oil spill clean-up and containment.
- Different embodiments for oil boom repair system are presented. In at least one embodiment, the oil boom repair system for boom repair includes two mirror image end connectors with a portion fabricated at 45-degrees from the plane surface of the other portion. The flexible liquid-impermeable curtain member is attached between the two rigid end connectors. The end connectors are also used to attach the oil boom repair system to a damaged, existing boom via the end connector's opening slot. This presented disclosure is used for repairing of reinforcing an existing boom by forming a tight seal between the curtain and existing boom with the use of the angled end connectors.
- Another embodiment presented introduced a suitable application method. This embodiment includes connecting one end connector of the instant oil boom repair system to an existing boom and engaging it to an existing boom connector. The second end connector is engaged with the boom on the other side of the damaged section so that the damaged area is covered by the extension of the curtain member, whereby the damaged section become isolated and sealed from the contaminated water. Both connections are attached by sliding the connectors over the existing boom. Next, the connectors are locked into place via a lock-pin mechanism. This embodiment also creates a tight seal over the damaged area, creating a “patch” to keep out oil contaminants from the protected area. The disclosed invention can be used to repair, patch, or reinforce an existing boom that could subject to the problems such as tears, saturation, or other damage.
- Another set of embodiments are used to reconfigure and extend existing
oil booms 202 so that they can be used more effectively and more safely. - Referring to
FIG. 8 &FIG. 9 , a pair ofend connectors 208 with a curtain member attached can function as an outer boom which protects a temporary opening made in a segment of the oil containment boom. Such an outer boom is needed in circumstances when, for example, a rookery area is protected by an oil containment boom, but where biologists or others need access to the rookery to examine or clean the birds. It would be dangerous to just uncouple the oil boom to create a temporary opening. The contamination on one side of the boom might be sufficient to flow through such an opening, and changing winds, waves, and weather might drive contamination through. The same danger exists in circumstances when an oil spill is contained within a closed boom, but there is a need to move workboats and barges into and out of the loop. In the described embodiment, theend connectors 208 are placed on either side of the intended temporary opening, with acurtain member 210 of sufficient length to encompass a boat, forming an outer boom. After the outer boom is put in place, the existingoil boom 202 can be safely uncoupled to form a temporary opening. - Referring to
FIG. 10 , an opening and closing gateway can be formed between two sections of existingboom 202 running very roughly parallel to each other by placing anend connector 208 on each existingboom 202, with each end connector attached to an end of acurtain member 210, where that curtain member has a standard butt joint which can be uncoupled to allow the curtain member to be used as an opening and closing gate. The illustrated embodiment uses two such gates separated by a significant expanse of water. The two gates provide a fail-safe closure, and the expanse of water between provides both a buffer against any oil that might breach the outer gate, and a decontamination area where any oil that might be clinging to the hull of a boat might be washed away. - Referring to
FIG. 11 , in circumstances of an oil spill being contained within a closed boom, the wind and current will tend to concentrate the oil at downwind portion of an existingoil boom 202. Such a condition is desirable because a thicker, concentrated oil is easier to recover. In order to prevent such a concentration of oil from dispersing with changing wind and current, an inner boom can be placed across a portion of the existingboom 202. A pair ofend connectors 208 with a proper length ofcurtain member 210 between forms such an inner boom. - Referring to
FIG. 12 , while an existingoil boom 202 deployed along a shoreline will protect that shoreline, the oil will still be difficult to collect and recover because wind and current along the shoreline will push the oil ever farther along the shoreline. An embodiment of the invention can be used to form an extension boom extending generally perpendicularly from the existingboom 202. Anend connector 208 is attached to the existingboom 202, and a length ofcurtain member 210 is attached to theend connector 208. The other end of thecurtain member 210 can be left free and can be anchored to maintain the extension boom in a useful position. With this arrangement, wind and current driven oil moving along a shoreline can be contained and recovered. - Referring to
FIG. 13 , in a channel of flowing water having a significant rate of flow, it is not possible to simply place a boom across the whole channel, because either the boom will be broken or dislodged or the oil will be pushed over or under the boom. An embodiment of the invention addresses that problem by providing one or more transverse extension booms that do not extend across the entire channel. Each transverse boom will collect some oil until the amount of collected oil reaches a maximum and spills over the free end of the transverse boom. A series of such transverse booms can form a cascade, collecting a significant amount of oil. As shown, the free ends of thecurtain members 210 forming the transverse booms can be anchored in place to maintain proper placement. - Referring to
FIG. 14 , in another embodiment, anend connector 208 is attached to an existingoil boom 202 across a channel of flowing water so as to form a chevron or angled boom, which forces oil contaminates toward the sides or shores. In most circumstances, it will be desirable to anchor theend connector 208 in order to preserve the chevron form. - Many further changes and modifications can be made in the present invention without departing from the spirit thereof. I therefore pray that my rights to the present invention be limited only by the scope of the appended claims.

5. The apparatus of claim 1 , where at least one said end connector attached to an end of a said curtain member is engaged with an oil containment boom such that said curtain member forms an extension boom extending generally perpendicular to the oil containment boom.
6. The apparatus of claim 1 , further comprising at least one said end connector attached to an end of a said curtain member, leaving the other end of said curtain member free, such that said curtain member forms a boom extending generally perpendicular to the oil containment boom across less than the full width of a channel of flowing water, thereby functioning as a cascade.
7. The apparatus of claim 1 , further comprising one end connector engaged with one oil containment boom anchored across a channel of flowing water such that said oil containment boom is formed into a chevron shape that deflects and concentrates oil contaminates.
8. The apparatus of claim 1 , further comprising one end connector engaged with one oil containment boom anchored across a channel of flowing water, said end connector being anchored in place, such that said oil containment boom is formed into a chevron shape that deflects and concentrates oil contaminates.
9. A method for repairing and reconfiguring an oil containment boom, the method comprising:
(i) providing at least one end connector having an elongated rigid planar body having a pair of planar portions oriented at an acute angle in relation to each other, one of the planar portions of the first end connector being provided with a T-shaped slot having a first part extending from the bottom edge of the body and a second part extending transversely to the first part, the second part being formed a distance below an upper edge of the body, where each said end connector is configured to engage the oil containment boom when lowered onto the oil containment boom;
(ii) providing at least one liquid-impermeable curtain member extending from and engageable with at least one said end connector, the curtain member having sufficient longitudinal and vertical dimensions to function as an extension of the oil containment boom when engaged with the boom;
(iii) engaging at least one said end connector with a said curtain member; and
(iv) engaging at least one said end connector engaged with a said curtain member to the oil containment boom such that the said curtain member functions as an extension of the oil containment boom.
10. The method of claim 9 , further comprising two said end connectors, both attached to an end of one said curtain member of sufficient length to form an outer boom, each said end connector being engaged with the oil containment boom such that the oil containment boom can be safely uncoupled to form a temporary opening in a location encompassed by said curtain member forming an outer boom.
11. The method of claim 9 , further comprising two said end connectors, each engaged with different oil containment booms running generally parallel each to the other, each said end connector attached to an end of a different said curtain member of sufficient length to form an outer boom extending a major portion of the distance between the generally parallel oil containment booms, where said curtain members form booms running generally parallel and in close proximity each to the other, forming a gate between the oil containment booms.
12. The method of claim 9 , further comprising two said end connectors, both attached to an end of one said curtain member of sufficient length to form an inner boom, each said end connector being engaged with the oil containment boom such that the portion of the oil containment boom enclosing a concentration of wind and current driven oil can be segregated by said curtain member forming an inner boom.
13. The method of claim 9 , where at least one said end connector attached to an end of a said curtain member is engaged with an oil containment boom such that said curtain member forms an extension boom extending generally perpendicular to the oil containment boom.
14. The method of claim 9 , further comprising at least one said end connector attached to an end of a said curtain member, leaving the other end of said curtain member free, such that said curtain member forms a boom extending generally perpendicular to the oil containment boom across less than the full width of a channel of flowing water, thereby functioning as a cascade.
15. The method of claim 9 , further comprising one end connector engaged with one oil containment boom anchored across a channel of flowing water such that said oil containment boom is formed into a chevron shape that deflects and concentrates oil contaminates.
16. The method of claim 9 , further comprising one end connector engaged with one oil containment boom anchored across a channel of flowing water, said end connector being anchored in place, such that said oil containment boom is formed into a chevron shape that deflects and concentrates oil contaminates.
