  • Publication number: 20210230975
    Abstract: Disclosed are systems and methods for thermal management of subsea conduits such as jumpers that provide the ability to alternate between cooling and heat retention of production fluids within the conduit as needed depending on the phase of operation. Adjustable insulation elements are provided on the conduits so that convective heat transfer between surrounding seawater and the conduit can be allowed or reduced. A control system can activate an alarm indicating the need to adjust the insulation depending on the temperature and/or flow rate of fluids in the conduit. Conventional conduits can be retrofitted by adding adjustable insulation elements to enable thermal management.

  • Publication number: 20210231249
    Abstract: Disclosed are systems and methods for thermal management of subsea interconnecting conduit such as jumpers that provide cooling and heat retention of production fluids within the jumpers. In a jumper circuit, parallel sections of jumper are provided having differing amounts of heat transfer between surrounding seawater and production fluids flowing within. Valving is provided to control fluid flow between the parallel sections of jumper, thus controlling the amount of heat transfer between the surrounding seawater and the jumper circuit. A control system can be used to generate an alarm based on fluid temperature and/or fluid flow rate within the jumper circuit indicating the need to adjust the valving to manage the temperature of fluids within the jumper circuit. Changes may be needed particularly depending on the phase of production, e.g., early life, normal operation, shut down and late life operation.

  • Publication number: 20210231250
    Abstract: Disclosed are systems and methods for thermal management of subsea conduits. A jumper that carries oil and/or gas produced from a subsea well in a subsea production facility located on a seabed has a first end for connecting to a first subsea component and a second end for connecting to a second subsea component. The jumper includes a jumper segment that is sloped relative to the horizontal, such that gravity assists with drainage of fluid from the second end of the jumper independent from fluid pressure in the jumper. At least a portion of the jumper is uninsulated to allow exchange of heat with seawater surrounding the jumper as produced fluid travels through the jumper. The amount of insulation on the jumper can be varied such that heat transfer from the production fluids to seawater surrounding the jumper circuit is adjusted as desired.

  • Publication number: 20210230976
    Abstract: Disclosed are systems and methods for thermal management of subsea jumpers that provide the ability to cool and/or retain heat in production fluids within the jumpers. The jumpers are provided with an annular pipe section surrounding the jumper circumferentially. The flow of a liquid cooling medium into an inlet and out an outlet of the annular pipe section can be controlled to provide cooling or heat retention as needed. A control system can be used to generate an alarm based on fluid temperature and/or fluid flow rate within the jumper indicating the need to adjust the flow of the cooling medium to manage the temperature of fluids within the jumper. Changes may be needed particularly depending on the phase of production, e.g., early life, normal operation, shut down and late life operation.

  • Publication number: 20200337223
    Abstract: An example agricultural machine comprises a material distribution system that includes a material distribution line configured to convey particulate material to a component. The agricultural machine comprises a sensing system that includes a first sensor configured to generate a first sensor signal indicative of a measure of a flow of the particulate material in the material distribution line, a second sensor configured to generate a second sensor signal indicative of a measure of the flow of the particulate material in the material distribution line, and a correlation generation component configured to receive indications of the first and second sensor signals and to generate a correlation metric that represents a correlation between the first and second sensor signals. In one example, the correlation metric is applied to a sensor signal from a second material distribution line to determine a flow rate in the second material distribution line.

  • Publication number: 20190242762
    Abstract: A handheld apparatus for measuring atmospheric temperature inversions consisting of a battery powered electronic display portion, a folding pole portion, and a temperature sensor protected from sources of heat radiation. An electronic circuit measures air temperatures at multiple heights accurately by automatically determining when readings have stabilized and reads a tilt sensor to assure temperature readings are at the proper height. Affixing said temperature sensor to the end of a pole while the opposite end is held in the user's hand facilitates waving of the temperature sensor end through the air to increase air flow, therefore, assuring quicker response and accurate air temperature readings. An electronic display indicates the presence and intensity of an atmospheric temperature inversion.

  • Patent number: 9114441
    Abstract: A handheld nozzle cleaning device includes a cylinder and piston disposed within the cylinder. The piston is movable between a latched position, in which air is compressed, and an unlatched position, in which air is drawn into the cylinder. The handheld nozzle cleaning device also includes a valve and a nozzle disposed at one end of the cylinder. Manual operation of the piston, defined by linear movement of the piston in a first direction, both releases the piston from the latched position and draws air into the cylinder. The compressed air flows out of the cylinder through the nozzle when the valve is opened. Also, manual operation of the piston in a second direction opposite the first direction both compresses air within the cylinder and secures the piston in the latched position.

  • Publication number: 20100277185
    Abstract: A soil moisture probe includes a capacitance-type probe and a detection circuit. The probe includes two spaced electrodes on the same side of a printed circuit board (PCB). The electrodes are placed on an inner layer of a multi-layer PCB and the detection circuit may be placed on an outer layer. The PCB also includes a ground plane. The detection circuit generates a sawtooth or triangular wave which is converted to a DC voltage representative of the moisture content of a soil sample into which the probe is inserted. The unique circuit uses the capacitance of the probe as part of a low-pass filter that distorts an oscillator-generated square wave into a saw-tooth or triangular wave. A resistance component of the low-pass filter is adjustable, allowing tuning of the probe and the circuit as needed.
