摘要： A system includes a subsea geothermal power system. The subsea geothermal power system includes a separator configured to separate a well fluid from a hydrocarbon well into a first fluid flow and a second fluid flow. The subsea geothermal power system also includes a geothermal power plant coupled to the separator. The geothermal power plant is configured to receive thermal energy from the second fluid flow and convert the thermal energy into at least one of electrical energy and mechanical energy. The separator is at least partially powered by the at least one of electrical energy and mechanical energy produced by the subsea geothermal power system.

摘要： This invention relates to a method and system for the three-dimensional reconstruction of material properties of a target using remotely located physical sensors using deep learning artificial intelligence. Utilizing the special technique disclosed here, the method provides an order of magnitude improvement in computational speed and memory requirements over current state-of-the-art artificial intelligence-based systems. The improvement in accuracy and resolution obtained enables high resolution imaging of buried infrastructure using above ground sensors mounted on drones and other devices. This makes it feasible to perform several first order inspection tasks related to pipeline health, corrosion, integrity, and others that are currently only possible using inline inspection tools such magnetic flux leakage (MFL) and ultrasonic (UT) sensors or via deployment of fiber optic sensors.

摘要： A modular subsea fluid storage unit comprises a variable-volume inner tank having a rigid top panel and a peripheral wall that is flexible by virtue of concertina formations. The peripheral wall is extensible and retractable vertically while the horizontal width of the tank remains substantially unchanged. A side wall of a lower housing part surrounds and is spaced horizontally from the peripheral wall of the inner tank to define a floodable gap between the peripheral wall and the side wall that surrounds the tank. An upper housing part extends over and is vertically spaced from the top panel of the inner tank and overlaps the side wall to enclose the inner tank. The floodable gap and the upper housing part enhance thermal insulation and trap any fluids that may leak from the inner tank.

摘要： Systems and methods for testing downhole power cables wherein such systems and methods utilize a mounting bracket having a PEEK insulator extending from a first face of said bracket and at least one flexible lead extending from a second face of said bracket. Such systems and methods may accommodate three such flexible leads that are configured to interface with power cables. A shunting block may be incorporated in a protective cap configured to fit over the PEEK insulator extension from said first face of said bracket.

摘要： Offshore systems and methods may be configured for offshore power generation and carbon dioxide injection for enhanced gas recovery for gas reservoirs. For example, a method may include: providing an offshore facility including a gas turbine, and a gas separator; producing a produced gas from a gas reservoir to the offshore facility; combusting the produced gas in a gas turbine to produce power and a flue gas; at least partially removing nitrogen from the flue gas in a gas separator to produce a carbon dioxide-enriched flue gas and a nitrogen-enriched flue gas; compressing the carbon dioxide-enriched flue gas in a gas compressor to produce a compressed gas; and injecting the compressed gas from the gas compressor into the gas reservoir, wherein 80 mol % or more of hydrocarbon in the produced gas is combusted and/or injected into the gas reservoir.

摘要： A subsea line clamp assembly (1) has a body (10) having an axis and a clamp member (50), assembled in segments around a subsea line (3), and tethered to a subsea anchor (5). The clamp member (50) is movably located within the body (10). The inner surface of the body (10) and the outer surface of the clamp member (50) have respective tapered portions as part of teeth (32, 72) arranged to inter-engage. Adjacent teeth (32, 72) may be separated by axis-parallel portions. The clamping force on the subsea line (30) can be maintained at a consistent clamping force throughout the service life of the subsea line (3), despite the actions of creep and compression acting to reduce the outer diameter of the line (3).
