A batch of wafer substrates is provided with each wafer substrate having a surface. Each surface is coated with a layer of material applied simultaneously to the surface of each of the batch of wafer substrates. The layer of material is applied to a thickness that varies less than four thickness percent across the surface and exclusive of an edge boundary and having a wafer-to-wafer thickness variation of less than three percent. The layer of material so applied is a silicon oxide, silicon nitride or silicon oxynitride with the layer of material being devoid of carbon and chlorine. Formation of silicon oxide or a silicon oxynitride requires the inclusion of a co-reactant. Silicon nitride is also formed with the inclusion of a nitrification co-reactant. A process for forming such a batch of wafer substrates involves feeding the precursor into a reactor containing a batch of wafer substrates and reacting the precursor at a wafer substrate temperature, total pressure, and precursor flow rate sufficient to create such a layer of material. The delivery of a precursor and co-reactant as needed through vertical tube injectors having multiple orifices with at least one orifice in registry with each of the batch of wafer substrates and exit slits within the reactor to create flow across the surface of each of the wafer substrates in the batch provides the within-wafer and wafer-to-wafer uniformity.

A system for use in petroleum production at sea includes a guide frame for one or more riser pipes, on a semisubmersible production vessel. One or more main buoyancy member are arranged separately on at least one riser to carry the main part of the riser's weight. Each riser separately carries a Christmas tree on its top, near a main deck of the vessel. The guide frame comprises vertical main elements extending vertically downwards from the deck, through the splash zone and through the upper, more wave- and current-influenced zone of the sea. The guide frame also includes horizontal guide plates comprising vertically open cells formed of a horizontally arranged framework of beams. Lateral stabilization devices guide the risers' and the main buoyancy members' vertical movement relative to the vessel and restrict horizontal movement of the risers with respect to the guide frame. The guide plates are arranged in at least two levels on the guide frame. A lower guide plate is arranged at the lower ends of the vertical main elements', and a guide plate is arranged just below or near the splash zone. At least one main buoyancy member is held on the riser in level with, and guided by, lateral stabilization devices arranged in one or more guide plates below the upper, more wave- and current-influenced zone near the sea surface. The risers are without buoyancy elements through the splash zone, and thus are less exposed to the water forces in the upper zone of the sea.

An adjustable riser for adjusting the elevational position of an irrigation sprinkler with respect to the surrounding ground level and / or with respect to the height of surrounding vegetation to be irrigated. The riser includes a movable cartridge within an internal bore of a housing having a plurality of catches outwardly projecting from the exterior wall of the cartridge and adapted to resiliently snap into or out of notches carried on the inner wall surface of the bore movably supporting the cartridge. The sprinkler is carried on a tube for discharging water while the opposite end of the tube includes an impact plate against which water pressure from the supply impinges. Upon impact, the tube with the sprinkler is forced upward within a housing against expansion of a spring, which normally urges the tube and sprinkler into a storage position within the housing. A linear adjustment of the riser, including the sprinkler and its tube, is effective by incorporating the cartridge with the catches movable within a toothed groove formed in the inner wall of the riser housing. The groove includes spaced-apart spiral teeth which are selectively engageable by the catches of the cartridge. Each of the catches are resiliently mounted in the cartridge and are yieldably urged into the notches or grooves for selective engagement with the teeth thereof.

A floated condenser extracts water from the sky. The condenser is part of or supplemental to a typical buoyed wind turbine set, comprising lift element, wind turbine, retention cable, electrical output, and base. The cable is hollow or coextensive with a lumen, the inner diameter thereof is water impermeable. The hollow / lumen stacks water over an accumulator, effecting a static base pressure p=ρgh. This pressure makes the water utilizable. After pressure multiplication—via a hydrostatic piston—or not, a first stream of water electrolyzes into liquid hydrogen and oxygen, one or both stored / sold directly. Another stream of water drives a turbine / motor or series hydroelectric turbines / motors, powering electrolysis and / or grid, the water then stored at moderate pressure for water utilities. Excess power from the wind turbine also supplements electrical output. A conductor runs along the cable. Gasified hydrogen is routed via the cable, lifting the condenser / turbine / kite.

A deck mounted pull riser tensioning system for a floating platform or vessel includes at least two cylinders having a cylinder body supported at an upper or lower end on a deck or tensioner support structure of the platform or vessel in spaced apart relation with the cylinder rods extending downwardly from the cylinder body, or vice versa. A load structure member is connected to lower ends of the cylinder rods or bodies and has an opening therethrough for receiving a portion of a riser extending from the seafloor. A vertically adjustable riser attachment supported on the load structure member over the opening attaches to a portion of the riser extending through the opening and generally centrally between the cylinders. The cylinders pull upwardly on the load structure member to exert an upward tensioning force on the riser at the location of the riser attachment.

A system is described for use at offshore locations of large depth, for mooring a production vessel or floating unit (14) at a location over a hydrocarbon reservoir (26) and for connecting risers (101) that can be carrying hydrocarbons up from the sea floor to a production vessel that stores the hydrocarbons, flowlines for water injection, gas lift, gas export, umbilicals and mooring lines that moor the vessel. Both the mooring lines and the risers are disconnectably connected to the vessel though a connection buoy, or connector (16). The invention concerns a system that allows a connector (16) to be used that is of minimum mass and volume, to ease its handling especially during its connection and disconnection to and from a vessel.

We provide an evaporator technology for treatment of produced water that may be deoiled water. Systems described herein utilize a vertical tube heat exchanger bundle where the brine is distributed in a falling film along the inside of the tube wall. Condensing steam causes a portion of the deoiled water to evaporate; this water vapor travels upward in a counterflow direction relative to the deoiled water. This evaporator technology provides several design advantages over the conventional vertical tube co-current flow evaporators (where the vapor flows downward with the falling film). These advantages include a minimal total installed cost (TIC) as well as offering optimal design features for water chemistry management.

The vibration inhibiting method comprises the following steps: firstly, the air guide sleeve which is enwrapped and fixed on the outer surface of the riser is prepared according to the outside diameter of the riser required to be protected; secondly, one flow disturbing rib or a plurality of flow disturbing ribs which are manufactured are fixed on the outer surface of the air guide sleeve in advance according to the screw pitch or the position of the spiral line which is predefined and marked on the outer surface of the air guide sleeve; and thirdly, the air guide sleeve provided with the flow disturbing rib is arranged on the outer surface of the riser. Therefore, the vibration inhibiting method and the vibration inhibiting device can effectively inhibit the vortex-induced vibration of the riser; the weight of the device can be reduced from 30 percent to 60 percent; and the construction cost can be greatly reduced.
