Patent number: 11795776Abstract: This disclosure includes manifolds, subsea valve modules, and related methods. Some manifolds and/or subsea valve modules include one or more inlets, each configured to receive hydraulic fluid from a fluid source, one or more outlets, each in selective fluid communication with at least one of the inlets, and one or more subsea valve assemblies, each configured to selectively control hydraulic fluid communication from at least one of the inlets to at least one of the outlets, where at least one of the outlets is configured to be in fluid communication with an actuation port of the hydraulically actuated device.Type: GrantFiled: April 1, 2021Date of Patent: October 24, 2023Assignee: TRANSOCEAN INNOVATION LABS LTDInventors: Guy Robert Babbitt, James Edward Kersey, Nicholas Paul Echter, Kristina Weyer-Geigel

Publication number: 20220412251Abstract: Typically, an engine-compressor for compressing natural gas for use as a fuel has a single cooling circuit to cool both its combustion unit and compression unit. A single cooling circuit design is not ideal because the optimal temperature for the combustion unit is higher than the compression unit of the engine-compressor. The present invention provides a dual zone cooling system to cool the combustion unit separately from the compression unit.Type: ApplicationFiled: February 11, 2022Publication date: December 29, 2022Inventors: Daniel S. PEDERSEN, Guy R. BABBITT, Kristina WEYER-GEIGEL

Patent number: 11346335Abstract: Most multistage compressors specify a maximum inlet pressure that may be supplied to the compressor to stay within designed limits. If the supply gas to be compressed is at a higher pressure than the specified maximum inlet pressure, then its pressure must be reduced before connecting it to the compressor. This pressure reduction is inefficient. The present invention avoids reducing the inlet pressure by routing the supply gas directly to the appropriate compression stage depending on its inlet pressure such that the compressor loads are still within the specified limits of the equipment.Type: GrantFiled: May 21, 2018Date of Patent: May 31, 2022Assignee: Onboard Dynamics LLCInventors: Nicholas Paul Echter, Kristina Weyer-Geigel

Patent number: 10968867Abstract: When a natural gas compressor completes its compression cycle, residual pressurized natural gas remains in the cylinders, valves, and conduits of the compressor. Gas leaks into the environment increasing greenhouse gas emissions and introducing safety concerns. The systems and methods herein provide ways for substantially reducing or eliminating leakage of natural gas to the atmosphere while the system sits idle between compression cycles.Type: GrantFiled: March 28, 2018Date of Patent: April 6, 2021Assignee: ONBOARD DYNAMICS, INC.Inventors: Nicholas Paul Echter, Kristina Weyer-Geigel

Publication number: 20210095614Abstract: An apparatus includes a valve and an actuator. The valve has a portion movably disposed within a valve pocket defined by a cylinder head of an engine. The valve is configured to move relative to the cylinder head a distance between a closed position and an opened position. The portion of the valve defines a flow opening that is in fluid communication with a cylinder of an engine when the valve is in the opened position. The actuator is configured to selectively vary the distance between the closed position and the opened position.Type: ApplicationFiled: May 4, 2020Publication date: April 1, 2021Applicant: JP Scope, Inc.Inventors: Charles PRICE, Jay MCFARLANE, Stephen John CHARLTON, William ANDERSON, David EVANS, Guy Robert BABBITT, Christopher Wayne TURNER, Daniel S.
