Patent number: 10690476Abstract: Integrated penetrator and proximity sensor probe assemblies are provided for monitoring a position of a rotating target within a subsea rotating device such as subsea motors and pumps. The integrated penetrator and proximity sensor probe assemblies are configured to communicate information related to the position of the rotating target through a wall of the device housing, and can be inserted through an opening in the wall of the device housing and mounted to the wall of the device to position a proximity sensor tip assembly adjacent the rotating target. The proximity sensor probe assemblies are pressure-compensated and configured to withstand subsea pressures and conditions.Type: GrantFiled: June 20, 2018Date of Patent: June 23, 2020Assignee: General Electric CompanyInventors: Lam Arthur Campbell, Dan Tho Lu, Svein Arild Haugen, Jens Abrahamsen

Patent number: 10451760Abstract: Systems and methods for monitoring subsea equipment are described herein. In one embodiment, such a system can include a plurality of acoustic sensor arrays that each include at least two acoustic sensors, wherein at least a first acoustic sensor array is mounted on an outer surface of subsea equipment being monitored and at least a second acoustic sensor array is positioned remote from the subsea equipment. The system can also include a digital data processor in communication with the plurality of acoustic sensor arrays, the digital data processor can be configured to process data from selected sensors of the plurality of acoustic sensor arrays to both selectively focus on a portion of the subsea equipment and to determine a point of origin of an acoustic signal. The system can be particularly useful in detecting leaks and other events in subsea drilling equipment.Type: GrantFiled: June 23, 2017Date of Patent: October 22, 2019Assignee: General Electric CompanyInventors: Svein Arild Haugen, Jens Abrahamsen, Geir Kjetil Nilsen

Patent number: 10024645Abstract: Sensor assemblies, electrical penetrator assemblies and associated methods are provided for monitoring operational characteristics of subsea rotating devices such as subsea motors and pumps. Pressure-compensated proximity sensors configured to withstand subsea pressures are disposed adjacent a subsea rotating shaft for directly monitoring a position of the rotating shaft during dynamic operation thereof. A sensor tip assembly includes a sensor cap and a sensing element therein configured to produce a signal indicative of a distance between the sensor cap and the rotating shaft. A substantially incompressible fluid is disposed within a fluid reservoir within a sensor housing, and fluidly communicates with the sensor cap such that at least a portion of an internal pressure within the sensor housing is applied to interior portions of the sensor cap. The sensor housing is configured such that the internal pressure increases in response to an increase in an external pressure of the sensor housing.Type: GrantFiled: April 28, 2017Date of Patent: July 17, 2018Inventors: Lam Arthur Campbell, Dan Tho Lu, Svein Arild Haugen, Jens Abrahamsen
