Abstract:
Exemplary embodiments are disclosed of liners, linings, and liquid containment vessels including the same. Also disclosed are exemplary method of providing liners and linings for liquid containment vessels, such as process tanks, immersion tanks, containment pits, gravity feed conduits for transferring or conveying liquid, etc. In an exemplary embodiment, a liner or lining is anchored to at least one structural component by at least one extrusion weld and at least one mechanical fastener. The mechanical fastener is coupled to the structural component. The extrusion weld is coupled to the mechanical fastener. The liner or lining may be anchored to a wide range of structural components, such as a frame, a framework, a frame member, a tank, a wall, a support member, a reinforcing member, an outer shell, a substrate (e.g., concrete, etc.) or sidewalls defining a pit or a gravity feed conduit, combinations thereof, other structures or components, etc.
Abstract:
A mooring system provides an anchor, imbedded in a sea floor from which arises a line to a mid-line float resisting entanglement by operation of a “worm grip” providing a tortuous path without exceeding permissible working loads nor reducing the tension capacity of the line. A slack region accommodates changing tides, before entering into an upright tube weighted at a lower end and flanged at an upper end thereof to secure a buoy in place. The embedded anchor is driven into the sea bed by hydraulic water jet drilling. From a thimble in the anchor to a thimble in the upright at the buoy, no intervening metal components are needed in the load path. Markings are durably and protectively embedded in recesses below the buoy's outer surface.
Abstract:
A method for handling a hydro sound absorber in the region of an offshore construction site. The method includes, prior to beginning noise-emitting work, positioning a hydro sound absorber in the region of the offshore construction site. The method includes positioning a transport housing receiving the hydro sound absorber close to at least one of a seabed or a surface of the water. The method also includes spreading out the hydro sound absorber from a first functional position out of the transport housing at least one of vertically to the extent of the offshore construction site or horizontally to the geometry of the seabed.
Abstract:
An improved sensor fish with robust design and enhanced measurement capabilities. This sensor fish contains sensors for acceleration, rotation, magnetic field intensity, pressure, and temperature. A low-power microcontroller collects data from the sensors and stores up to 5 minutes of data on a non-volatile flash memory. A rechargeable battery supplies power to the sensor fish. A recovery system helps locating sensor fish. The package, when ready for use is nearly neutrally buoyant and thus mimics the behavior of an actual fish.
Abstract:
A buoy and mooring system provides a robust buoy protective of markings thereon, easily retrieved for inspection and service, weighted and levered for maintaining self-righting, vertical orientation and anchored with a non-corroding system of connectors and links running from surface to sea floor. A mid-line float resists entanglement, and can be installed or uninstalled by operation of various “worm grip” mechanisms. A slack line region accommodates changing tides. An upright tube, weighted at a lower end and flanged at an upper end thereof, secures a buoy in place but pulls up through the buoy for easy retrieval by boat crews. Embedding an anchor is by hydraulic water jet drilling. From a thimble in the anchor to a thimble in the upright at the buoy, no intervening metal components are needed in the load path. Markings are durably and protectively embedded in recesses below the buoy's outer surface.
Abstract:
This invention corresponds to a flotation device comprising a cylindrical body having perimetral flotation cavities; a predetermined quantity of air deposited and enclosed in each of such cavities; and covers to cover said cavities.
Abstract:
A pressure compensator is disclosed for a subsea electric installation, which includes a rigid bottle and a flexible bag placed in the rigid bottle, the pressure compensator including a first opening at a first end of the pressure compensator allowing fluid communication of an insulating medium arranged to intermediate space between the rigid bottle and the flexible bag, a second opening at a second end of the pressure compensator allowing fluid communication of seawater arranged within the flexible bag; and a bypass channel providing fluid communication between two points in the intermediate space of the pressure compensator.
Abstract:
A device (10) for collecting and temporarily storing fluids (16) escaping from an underwater source (12, 64) and having lower density than surrounding water includes a collector (18) placed over the underwater source for collecting the escaping fluids, a riser tube (20) for transferring the collected fluids together towards the surface; and a buoyant buffer reservoir (22) maintained submerged under the surface and having an open-bottom chamber (30) for storage of the fluids. The riser tube has flow restrictors has flow restrictors comprising choke disks (58, 58′) arranged in its interior for restricting the flow of the fluids. The flow restrictors are arranged along the length of the riser tube. The buffer reservoir has arranged in its chamber a separator vessel (32) for separating gas from the fluids. The riser tube opens into the interior of the separator for discharging the fluids.
