  • Patent number: 11656106
    Abstract: A subsea housing assembly, in particular for a subsea sensor, includes a first housing portion and a second housing portion. The first housing portion includes a first electrical connection for data communication and the second housing portion includes a second electrical connection for data communication. A wall provides separation between the first housing portion and the second housing portion of the subsea housing. An inductive coupler, that includes a first coupling section disposed in the first housing portion and a second coupling section disposed in the second housing portion, is provided. The inductive coupler is configured to provide inductive coupling across the wall for providing at least a data communication between the first and second electrical connections.

  • Publication number: 20230022527
    Abstract: A subsea sensor module includes a sensor housing having a first section, a second section and a third section, each section having an outer profile and a module flange having an inner profile. An outer surface of the flange is substantially perpendicular to an outer surface of the housing in the first section. The housing outer profile and flange inner profile are substantially the same along the second section of the housing. A shoulder is formed in the housing outer profile in the third section by a transition of the diameter of the outer profile from a smaller to a larger diameter. The flange has a corresponding shoulder in the flange inner profile; wherein the flange is shrink fit mounted radially outwardly of the sensor housing second section such that the shoulders are in contact.

  • Patent number: 10578467
    Abstract: A subsea flow meter assembly includes a pipe section extending in an axial direction and providing a flow path for a medium. At least four measuring ports are provided at different locations in the pipe section. A first assembly measures at least a differential pressure between a first and second ports and an absolute pressure at one of the ports. A second assembly measures a differential pressure between a third and a fourth ports, and an absolute pressure at one of the ports. A first measuring unit is used to take measurements of the differential pressure and the absolute pressure via the first sensor assembly. A second measuring unit is used to take measurements of the differential pressure and the absolute pressure via the second sensor assembly. An evaluation unit of each determines a flow rate of a flow of medium through the pipe section based on the measurements.
