摘要： A long, vertically disposed ocean water upwelling pipe, such as a cold water riser in an ocean thermal energy conversion facility, is fitted at its lower inlet end with a self-cleaning inlet screen. The screen includes a right conical frustum of loose metal netting connected at its larger upper end to the lower end of the pipe. A heavy, negatively buoyant closure is connected across the lower end of the frustum. A weight is suspended below the closure on a line which passes loosely through the closure into the interior of the screen. The line tends to stay stationary as the lower end of the pipe moves, as in response to ocean current vortex shedding and other causes, thus causing the closure to rattle on the line and to shake the netting. The included half-angle of the frustum is about 20.degree. so that, on shaking of the netting, marine life accumulated on the netting becomes loose and falls free of the netting.

摘要： An ocean thermal energy conversion facility includes a long pipe assembly which is supported at its upper end by the hull of the floating facility. Cold water flows to the facility from deep in the ocean. The pipe assembly comprises an elongate pipe construction and a weight connected to the lower end of the construction by a line of selected length. A floatation collar is connected to the construction at its upper end to cause the construction to have positive buoyancy and a center of buoyancy closer to the upper end of the construction than its center of mass. The weight renders the entire pipe assembly negatively buoyant. In the event that support of the pipe assembly should be lost, as by release of the assembly from the facility hull in an emergency, the assembly sinks to the ocean floor where it is moored by the weight. The pipe construction floats submerged above the ocean floor in a substantially vertical attitude which facilitates recovery of the assembly.

摘要： Apparatus for drilling a well at a location submerged below a body of water includes a buoyant foundation structure. The foundation structure is floatable on the surface of the body of water and is subject to vertical motion in response to waves and the like. A riser handling and tensioning mechanism is mounted to the foundation structure and is operable for moving a riser pipe along a substantially vertical line from and to the foundation into and out of connection with the submerged location. The riser handling and tensioning mechanism is also operable for applying tension to a riser pipe connected to the submerged location. The handling and tensioning mechanism includes vertically disposed hydraulic rams mounted to the foundation structure. Holding means are releasably engageable with a riser pipe adjacent its upper end and are connected to the rams for movement along the riser line by the rams. The rams have an active operating mode in which they are operable to lower and raise a riser pipe along the line into and out of connection of the lower end of the riser with the submerged location. The rams also have a passive operating mode in which they are operable to apply a selected upward force to a riser engaged in the holding means and connected to the submerged location during vertical motion of the foundation structure.

摘要： A jackdown tension leg platform is set forth which may be used for processing a commodity liberated from the ocean floor by one or more wells. The platform includes a closed buoyant hull which houses production equipment and at least one connector disposed on the hull for vertical relative movement. The connector has one end secured to the ocean floor and is moved upwardly relative to the hull to submerge the hull to a depth below the majority of the ocean's hydrostatic forces and, at the same time, tension the connector to hold and stabilize the hull over the wells. Conduits are connected between the wells and the submerged hull and between the hull and the surface. A crew module may be provided above the surface atop the connector with a trunk disposed between the module and submerged hull to provide access therebetween. Additionally, where the commodity is combined at a manifold located in a closed ocean floor mounted shell, a descending and ascending capsule may be provided to transport crew members between the shell and submerged hull.

摘要： A large diameter duct structure is adapted for vertical disposition in an ocean. An elongate tensile core assembly is adapted to be supported at one end, as from a floating platform, and to extend downwardly a desired distance. A plurality of duct wall sections, each of selected length, are alignable in serial order to define a tubular assembly having a diameter substantially greater than that of the core. Support means are engageable with the core at selected locations along the core and with the wall sections. The support means support the wall section substantially concentrically about the core and secure the wall sections from movement relatively along the core. Seals are engageable between the ends of adjacent wall sections disposed about and along the core, and define substantially liquid-tight connections between the wall sections. When the several wall sections are serially disposed along the core and are supported on the core with the seals engaged between adjacent wall sections, the result is a fluid flow duct of large diameter in which the weight of the duct is supported by the core which is loaded in tension below its upper end.

摘要： A gravity-type offshore structure, useful as an offshore drilling platform, e.g., is provided for use in ice-covered waters such as offshore of the Alaskan and Canadian North Slope. The structure is composed of a plurality of floatable and controllably ballastable modules, each of which can be fully submerged. The modules are stackable by selective ballasting and deballasting operations in a suitable sequence to define a mobile offshore structure. The structure is assemblable adjacent a site of use and is floatable after assembly to, from and between successive sites of use. At each site of use the assembled structure is ballasted by sea water to be supported by the sea floor and to have sufficient deadweight, in combination with its support by the sea floor, to stand against ice loads urging the structure laterally of the site. Major ones of the modules preferably are constructed of reinforced concrete arranged within the modules in a honeycomb cellular fashion. A reinforced concrete armor belt is removably installed around the structure at its on-site load waterline. The structure is useful in a range of water depths. The armor belt is mountable to the structure at a number of different elevations on the structure to suit differing on-site load waterline locations. Individual modules can be used with other modules of the same or different size in a series of offshore structures individually useful in a characteristic range of water depths.

摘要： A mobile offshore platform has a buoyant and ballastable mat base of substantial horizontal extent. A cylindrical pylon is fixed to and extends upwardly from the center of the base. The pylon has a height greater than the maximum operating water depth of the platform. A positively buoyant deck unit has a central opening through it within which the pylon cooperates. The deck unit is movable vertically along the pylon in response to the operation of jacking mechanisms and cooperating jacking legs located adjacent the corners of the deck unit. The jacking legs are engageable at their lower ends with the base whereby operation of the jacking mechanism causes the deck unit to be moved vertically along the pylon relative to the base. In use, the deck unit is elevated to the top of the pylon after the base is submerged into contact with a sea floor and the jacking legs are thereafter disposed in a retracted position with their lower ends adjacent the deck unit. In use, the deck unit is disposed above the water surface. The platform is especially suited for use in ice-covered waters on the margins of the Arctic Ocean.
