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.

Subsea sensor module, system and method

A subsea assembly includes a housing having a flange interface for interfacing with a flange of a process fluid carrying component, wherein the housing is configured such that boltheads or nuts exerting a fastening force on the subsea assembly when mounted to the process fluid carrying component are spaced from the flange interface so that the dimensions of the housing of the subsea assembly at the flange interface are not affected by a space required for a bolthead or nut fastening tool.

Subsea assembly

A connection assembly includes an adapter to be mounted to a rear part of a subsea sensor, a sensor port being located in the adapter, through which at least a first and a second sensor connection are led to the subsea sensor; a first port for providing a connection to a first of the subsea cables; and a second port for providing a connection to a second of the subsea cables. A first penetrator is arranged in the first port to provide a liquid tight seal between an interior space of the adapter and a duct connected to the first port leading the first sensor connection through the first port, and a second penetrator is arranged in the second port providing a liquid tight seal between the interior space of the adapter and a duct connected to the second port and leading the second sensor connection through the second port.

Connection assembly, sensor assembly and subsea cable harness

A penetrator assembly, for high pressure and/or subsea applications, includes a body. The body includes a first end surface, in operation subject to a pressure of a high pressure environment; a second end surface distanced from the first end surface, which in operation is subject to a pressure of a low pressure environment; at least one connecting passage connecting the first end surface to the second end surface; at least one groove extending from the first end surface towards the second end surface, being distanced from second end surface and surrounding the connecting passage and including an annular opening on the first end surface; and annular lips between a first portion of connecting passage adjacent to the first end surface and the groove, the annular lips in operation being subject to the pressure of the high pressure environment and providing a pressure balance around the first portion of connecting passage.

Penetrator device for high pressure application

A method of manufacturing a differential pressure sensor is provided. The method includes providing a housing of a differential pressure sensor and a cover. The cover is mounted to the housing so as to form a pressure chamber. The differential pressure sensor is configured such that in operation, a pressure to be measured is transmitted into the pressure chamber. The method further includes heating a sleeve, placing the heated sleeve around the cover and the housing and allowing the sleeve to cool.
