The present invention generally relates to containment and control of an oil spill caused by a damaged or broken riser in deepwater. More specifically, the present invention relates to a reusable unit that will contain oil spills to a specific location and will also allow oil to be harvested as it flows to the top of the unit while minimizing or even eliminating any environmental clean-up cost. The unit of the present invention is dropped over a damaged or broken riser in a closed position, the unit is released and stabilized in sections until the surface is reached and the containment unit is completely erected.

A bio-friendly water flow control system can include a portable structure adapted to contain organic waste material. The water flow control system can be configured for deployment outdoors to guide water flow to limit erosion. A portable structure of such a system can include a sheath that is configured to contain waste material within an interior of the sheath. The portable structure may be configured to allow a flow of water into the interior of the sheath. The portable structure may include a waste material that includes processed palm frond particles. The portable structure may be configured to absorb a weight of water at least 50% greater than a dry weight of the portable structure.

The disclosed technology includes temporary support structures for use in the repair of a transmission tower. A typical transmission tower includes a tripod that receive the load of the tower and distributes it to piles embedded in the ground. A temporary support structure may temporarily remove the load of the transmission tower from the tripod to allow the tripod to be removed and replaced with a new tripod. A temporary support system may include a pile temporary support system, a beam support structure supported by the pile temporary support system, and a flower pot adapter lifting assembly configured to attach to a portion of the transmission tower to transfer a load of the transmission tower to the beam support structure.

A stack of crane mats can be lifted by a sling which engages two or more lifting portions mounted to recessed walls. The lifting portions are configured such that a sling can lift a stack of mats. Each lifting portion includes an arm having a proximal end attached to a recessed wall of the mat and a distal end attached to a plate. A protrusion is mounted on each arm such that when the mats are stacked, the protrusions over lower mats are nested within recessed cutouts of upper mats. After a stack is landed, the sling may retain one or more upper crane mats and lift them away from a lower crane mat.

An edge protection safety bund system (10) for use in connection with a rock bund made of rock fill. The edge protection safety bund system (10) comprises a bund module (12) having a barrier wall (14) and a base plate (16). The bund module (12) is preferably one of a plurality of bund modules (12) arranged side by side to form an extended barrier wall (14). The barrier wall (14) of each module (12) extends substantially perpendicularly upwards from the base plate (16), and a support web (18) extends at an angle from a rear face of the barrier wall (14) to an upper surface of the base plate (16). In use, when rock fill is dumped onto the rear of the bund modules (12), and allowed to flow back to its natural angle of repose behind the barrier walls (14), it creates a rock bund (20) with a front face formed by the extended barrier wall (14).

Presented herein are systems, methods, and apparatus related to relocatable tower technologies that facilitate on-site deployment and provide improved stiffness in order to minimize motion at a tower top in a manner that existing approaches, which focus on survivability, do not contemplate. In particular, relocatable tower technologies described herein can be deployed rapidly and at low cost, at outdoor sites, to, e.g., provide a vertical mast upon which equipment can be mounted. In certain embodiments, features of relocatable towers described herein allow the vertical mast to survive and remain rigid while being exposed to outdoor elements, such as wind gusts (e.g., up to 110 Mph). Advantages of relocatable tower technologies described herein are particularly well suited where (e.g., scanning based) imaging and/or detection equipment is mounted at a top of the tower, and/or where towers are deployed at sensitive sites such as hydrocarbon production, storage and processing facilities.

A stack of crane mats can be lifted by a sling which engages two or more lifting portions mounted to recessed walls. The lifting portions are configured such that a sling can lift a stack of mats. Each lifting portion includes an arm having a proximal end attached to a recessed wall of the mat and a distal end attached to a plate. A protrusion is mounted on each arm such that when the mats are stacked, the protrusions over lower mats are nested within recessed cutouts of upper mats. After a stack is landed, the sling may retain one or more upper crane mats and lift them away from a lower crane mat.

A fully recoverable modular steel footing and beam system that allows installation of the rapidly deployable prefabricated folding building system on a wide variety of substrates, including bare earth, existing asphalt, and existing concrete. The substrate may show deviation from level and still be accommodated. The invention also includes three-part folding haunch and ridge braces allowing braces to ship attached to building panels resulting in minimal handling, reduced weights, and ability to install roof and walls separately. Roof weight is reduced and so can be handled with a forklift or telehandler, as the only heavy equipment needed to erect the building. Flashings are insulated, factory cut, and drilled for bolts, in alignable pattern to bolt-receiving rivets installed in the corrugated siding and roofing. Bolts and bolt installation locations are color coded.
