摘要:
A conductor arrangement is for a collection of subterranean wells for recovering fluids from an underground structure. A frame is provided with several conductor guides, each forming an inlet opening for a conductor in an upper portion of the frame and an outlet opening for the conductor in a lower portion of the frame. The conductor is arranged to border a portion of a borehole towards a surrounding unconsolidated mass and has been passed through the conductor guide and down into the unconsolidated mass. The conductor guides are arranged in a mutually diverging manner in the direction from the inlet opening, and each conductor is extendable by a bend, the deflection angle of the bends providing mutually parallel center axes in coupling interfaces arranged in upper end portions of the bends.

The present invention relates generally to a modular locking and retaining mechanical design solution to reliably secure immersed, unrestrained and un-powered objects in a fluid environment to a fixed support surface such as a mounting frame or panel, with a quick connect/disconnect engagement method by a diver (i.e. manual mate) or remote-operated vehicles (ROVs) mate, into a fixed mounting frame or panel installed at a subsea deployed platform for oil and gas offshore applications.

Support structures for electrohydraulic apparatuses in particular of electrical and hydraulic apparatuses of irrigation systems are disclosed. The support structure is configured to be applied to a buriable well for housing and protecting such electrohydraulic apparatuses. On predetermined portions of the support structure a plurality of holes are formed, and are adapted for receiving a corresponding plurality of support means configured to hold, preferably in a releasable manner, one or more electrohydraulic apparatuses. Also described is a buriable well for housing and protecting electrohydraulic apparatuses comprising at least one such support structure of electrohydraulic apparatuses.
摘要:
An embedded housing system storing cables below the surface in a protected environment, with a moveable surface lid lying flush with the existing surface and following the crown or slope across the travel path. The cables are readily raised out of the housing structure to obstruct traffic across the travel path, or lowered into the housing system to allow unobstructed traffic passage. Single cables, multiple cables, and utility lines can be enclosed and remain protected within the housing support structure. Once raised, the cables can be attached to an end support. The housing support structure is prefabricated in sections, selectively attached to match the existing crown or slope across the travel path, and then installed below the surface. The flush surface lid of the cable housing structure is only about 8 inches wide, and can be locked while in the closed position. Surface lid sections remain connected while opening simultaneously across the sloping travel path, using an interlocking mechanism. Rain water is inhibited from entering the housing support structure by the surface lid, but if it seeps inside, it will drain away by gravity. Ice and snow is melted by a heating device.

A bundle of cables includes at least two underwater cables and a fastener for fastening the underwater cables together. The fastener is water-soluble, biologically decomposable and/or chemically decomposable. A method of laying at least two underwater cables simultaneously from a vessel and a method of using a water-soluble, biologically decomposable and/or chemically decomposable fastener to fasten at least two underwater cables together to form a bundle of cables are also described.
摘要:
Novel tools and techniques are provided for implementing MediaLink Interconnection Boxes (“MIBs”). In some embodiments, a plurality of MediaLink Interconnection Boxes (“MIBs”) or media interconnection devices, which may be disposed throughout a recreational vehicle (“RV”) park or other bulk service provider application sites, or the like, may serve as demarcation units designed to each provide an accessible indoor or outdoor interface where long-term or temporary/transient customers can directly connect to land line service (e.g., POTS service), video or television service, and/or Ethernet or Internet services provided by one or more service providers. Fiber-to-Drop-Point (“FTDP”) and/or point-to-point fiber insertion within a passive optical network (“PON”) communications system may be implemented using apical conduit systems in conjunction with the MIBs. Alternatively, traditional ground-based or buried line interconnections (or a combination of the apical conduit system and such traditional interconnections) may be implemented in conjunction with the MIBs.

A method of installing an off-shore tidal hydroelectric turbine generator is described. The method provides for a number of safety features, ensuring that all components are safe to handle during the installation operation, and also ensuring that the turbine will not start spinning during the installation operation.

An electrical subsea node for communicating data between at least one sensor at a sea bottom and a topside unit above the sea surface may include: a water tight container; a first electronic module extending in a first area of a first area size in a plane of a maximal spatial extent of the first electronic module; and at least one second electronic module extending in a second area of a second area size in a plane of a maximal spatial extent of the second electronic module, wherein the first and second electronic modules are coupled for data communication and arranged inside the container to form a module arrangement extending in an arrangement area of an arrangement area size in a plane of a maximal spatial extent of the module arrangement, wherein the arrangement area size is smaller than a sum of the first and second area sizes.
摘要:
A method for laying cable from a vessel at a near shore location in shallow water to shore. The cable on the vessel is wrapped around a modified roller quadrant on the vessel. The roller quadrant is moved from the vessel into the water. A pulling device is attached by a line to the roller quadrant. The pulling device is used to pull the roller quadrant and cable toward shore. The pulling device may be positioned in the water and moved to shore as required. The pulling device may also be initially positioned on shore. The roller quadrant may include a skid and buoyancy modules to reduce the pulling force required to move the roller quadrant and lay the cable to shore.
