  • Patent number: 12012833
    Abstract: In a system for producing power and capturing carbon dioxide (CO2) at an offshore site, separator units separate a fluid produced from an offshore vessel in fluid communication with a reservoir into water, oil, and gas. The gas is sent to oxy-firing gas turbine generator units. Air separation units separate an air into nitrogen and oxygen. The oxygen is sent to the oxy-firing gas turbine generator units. Gas compression units compress an exhaust gas from the oxy-firing gas turbine generator units. Dehydration units dehydrate the compressed exhaust gas, and a portion of the dehydrated compressed exhaust gas is recycled back to the oxy-firing gas turbine generator units. Gas pumps inject a remaining portion of the dehydrated compressed exhaust gas into the reservoir. Additionally, the oxy-firing gas turbine generator units generates electricity with the oxygen, the gas, and the portion of the dehydrated compressed exhaust gas.

  • Publication number: 20220316939
    Abstract: A smart wave energy converter may include a reconfigurable floater; a reference wave frequency measurement module; a central control module; a submerged buoyancy element; one or more power take-off devices; and an anchoring system. The reconfigurable floater may be connected to the submerged buoyancy element by the one or more power take-off devices. The submerged buoyance element may be connected to the anchoring system. The reconfigurable floater may include one or more mechanisms to alter a natural heave frequency of the reconfigurable floater. The reference wave frequency measurement module may measure a frequency of a wave state and transmit a measured frequency to the central control module. The central control module may adjust a property of the one or more mechanisms to match the natural heave frequency of the reconfigurable floater to the measured frequency.

  • Publication number: 20220316446
    Abstract: A floating offshore wind turbine assembly unit useful for assembling or maintaining wind turbines at an offshore location is disclosed. The floating offshore wind turbine assembly unit may include a first vessel spaced a distance apart from a second vessel, and an extended deck coupled to the first vessel and the second vessel. The extended deck is positioned in the distance between the first vessel and the second vessel, and the extended deck is configured as a dry dock disposed or movable to a height above a sea level. In some embodiments, the extended deck or a portion thereof is movably coupled to the first vessel and the second vessel. For example, the extended deck or a portion thereof is movable between a submerged or near sea level position and a position above a sea level.
