Abstract: A valve for maintaining a given level of liquid in a tank, reservoir, or other container having a liquid-gas interface. Said valve being actuated by a float that rises and falls along with the liquid in the container. Said valve float actuates a series of valves in sequence wherein the higher the float rises, the more valve ports are opened allowing a higher flow rate through the valve.

Abstract: A contraflow gas/liquid contactor tower having a gas diffuser to provide uniform gas flow in the tower, a set of partial helical membrane sheets running generally parallel to the tower axis and the gas flow, supported between an upper liquid distributing hub and a lower support hub, and a mist extractor pack with liquid direction control.

Abstract: A method of installing piles for offshore platforms consisting of a rotating clamp attached to the structure through which the pile can slide until driven to a required depth, and then tightened to secure the pile. The pile may be made up and inserted in a vertical position until the pile tip reaches the seabed. The pile is then rotated to its permanent position and driven to a required depth.

Abstract: A mobile offshore platform in which a support structure receives interchangeable barges thereon for carrying out the different functions required in producing an offshore hydrocarbon reservoir. The mobile offshore platform includes a plurality of support legs extending into the water down to the ocean floor. Jacking mechanisms engage each support leg to raise and lower a negatively buoyant, open network platform structure relative to the surface of the water. A barge having a process plant installed on board is docked in position on the platform structure. A heave absorber disposed above the surface level of the platform structure engages the bottom of the barge to dampen vertical motion thereof. The platform structure and the barge are raised above the water to the required height, whereupon the platform structure is secured to the legs and the jacks may be removed for use on another platform.
