  • Patent number: 5733066
    Abstract: A hazardous waste containment vessel, and a method for its use, for safe, permanent disposal of hazardous waste in deep ocean pelagic sediment. The hazardous waste containment vessel is dropped into deep ocean water, descends through the water and penetrates the deep ocean pelagic sediment, thus burying the hazardous waste containment vessel in deep ocean pelagic sediment. The hazardous waste containment vessel has an elongated laminar walled container having first and second ends. The first end tapers to an apex having an angle selected to enhance penetration of the deep ocean pelagic sediment by the hazardous waste containment vessel. A dense filler material is carried within the elongated laminar walled container and isolates at least one hazardous waste containing drum member that is suspended within the dense filler material, from the interior layer of the elongated container member and from additional drum members suspended within the dense filler material.

  • Patent number: 5516233
    Abstract: A water safety and survival system that provides a multi-chambered personal flotation device that operates on minimal volume to create a single heads up righting moment that reliably stabilizes an unconscious victim with his airway out of the water. This is accomplished with a minimal amount of lift, less deflated bulk, improved cosmetic appeal and reduced cost. These combined advances result in a safety vest conducive to actually being worn, a key feature for a safety vest. The system also provides for incorporation of a separating second inflatable life ring, rescue board, artificial respiration assist platform and ultimately a raft for removal of the victim from the water to protect him from hypothermia. This sequentially inflated, multi-chambered, multi-faceted inflatable rescue product is incorporated within the body of the safety vest.

  • Patent number: 5498108
    Abstract: An anchoring device comprises an elongated element (1) introduceable into a hole (10) and means for securing the element against withdrawal from the hole. The securing means comprise at least one part (5, 13, 16) movably connected to the elongated element (1) and adapted to project transversely beyond the periphery of the element to be brought into contact with a wall (12) of the hole. The part is adapted to move, on traction of the element (1) introduced into the hole (10) in a direction out of the hole, relative to the element (1) by means of friction generation against the hole wall (12) while increasing the combined transverse dimension of element (1) and part (5, 13, 16) to the corresponding transverse dimension of the hole and to tend to increase this combined transverse dimension further on continued traction in the element.

  • Patent number: 5486070
    Abstract: A method for conducting offshore well operations is disclosed in which a compliant platform is restrained out of its normal position substantially over a well pattern by adjusting a first lateral mooring system connecting the compliant platform to a first array of anchors secured to an ocean floor. An offshore drilling vessel is then positioned over a selected well site of the well pattern at a location at the surface of the water not accessible to the offshore drilling vessel with the compliant platform in its normal position by adjusting a second lateral mooring system connecting the compliant platform to a second array of anchors on the ocean floor. Well operations are then conducted through a substantially vertical riser while maintaining a clearance to prevent direct contact between the compliant platform and the offshore drilling vessel.

  • Patent number: 5480266
    Abstract: A tensioned riser deepwater platform suitable for offshore oil and gas applications is disclosed having a foundation secured to the ocean floor, a topside facility above the ocean surface, and a vertically extending tower jacket secured to the foundation and supporting the topside facility. A plurality of substantially vertically extending risers provide fluid communication between the wells and the topside facility. These risers are connected to riser supports near their upper ends and the riser supports provide the principal load transfer between the risers and the tower jacket. Thus, the conductor guides and attendant horizontal bracing of conventional deepwater design can be substantially eliminated.

  • Patent number: 5479726
    Abstract: A padding machine attachment for a vehicle is provided. When padding of a ditch for a pipeline or cable is required, the padding machine is removably attached in a position at one end of a conventional bucket loader, bulldozer, or other base machine or vehicle, whereby said attachment moves along the path of travel of the vehicle. As the vehicle moves the padding machine attachment along one side of the pipeline ditch, the padding machine attachment picks up at least a portion of a pile of excavated material placed parallel to and along the same side of the ditch and processes the excavated material into padding material for placement into the ditch for padding the pipeline or cable.

  • Patent number: 5479728
    Abstract: A backfiller and tamper unit (10) is disclosed which is a self contained unit that acts to both backfill and compact soil into a trench for complete restoration. The unit includes a tractor (12) which mounts a vibrator and tamping wheel assembly (14) and a backfill auger assembly (16). The vibrator and tamping wheel assembly (14) is mounted on a mast (50) which is pivotally secured to the tractor for limited arcuate motion from vertical. This permits the mast to be tilted so that the compaction force of the vibrator and tamping wheel assembly is most effectively directed to compact the soil in the trench. The vibrator and tamping wheel assembly is free floating on the mast which isolates the tractor from vibration generated by the vibrator and tamping wheel assembly and provides greater compaction efficiency. Further, the vibrator and tamping wheel assembly can be lifted vertically on the mast by a lift mechanism (62) for storage.

  • Patent number: 5480260
    Abstract: A method and system for collecting ground water segregated from storm water are provided in which an existing storm sewer pipe may be retrofitted by forming a ground water channel and a storm water channel therein. The two channels may be formed by disposing a lining within the existing pipe which segregates the pipe into two distinct flow passageways. A new pipe may also be similarly used for collection of ground water.

  • Patent number: 5478167
    Abstract: A streamwise-vortex generating diverter is placed upstream from a structure to protect the structure. The diverter is positioned to induce a vortex, or rotation, in the current flow whose axis is essentially parallel to the streamwise flow. This rotating flow persists downstream of the diverter effectively guiding debris away from the protected structure.
