Abstract: 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.

Abstract: 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.

Abstract: 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.

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.

Abstract: A connection assembly connects at least two subsea cables to a dual output subsea sensor An embodiment includes an adapter piece mounted to a rear part of the subsea sensor; a sensor port in the adapter piece, through which at least a first sensor connection and a second sensor connection are led to the subsea sensor; a first and second port for respectively providing a connection to a first and second subsea cable; a first penetrator providing a liquid tight seal between an interior space of the adapter piece and a duct connected to the first port; and a second penetrator providing a liquid tight seal between the interior space of the adapter piece and a duct connected to the second port. The sealing provided by the first and second penetrator preventing fluid communication between the respective duct connected to the first and second port, through the adapter piece.
