A subsea boosting module for use with an alternating current (AC) power system includes a housing defining at least one interior chamber. A fluid pump is disposed within the interior chamber. An electric motor is disposed within the interior chamber and drivingly coupled to the fluid pump. A plurality of power components is disposed within the interior chamber to deliver power to the electric motor.

Methods and systems for subsea boosting with direct current and alternating current power systems

A subsea power distribution module includes an outer vessel defining an interior chamber and a plurality of power modules disposed within the interior chamber. The outer vessel is configured to maintain a pressure within the interior chamber substantially the same as an ambient pressure outside the outer vessel. Each power module includes a pressure vessel defining an interior chamber and a power converter disposed within the interior chamber of the pressure vessel. Each pressure vessel is configured to maintain a substantially constant pressure within the interior chamber of the pressure vessel.

Methods and systems for subsea direct current power distribution

A subsea boosting module for use with a direct current (DC) power system includes a housing defining at least one interior chamber. A fluid pump is disposed within the interior chamber. An electric motor is disposed within the interior chamber and drivingly coupled to the fluid pump. A plurality of power components is disposed within the interior chamber to deliver power to the electric motor.

Methods and systems for direct current power system subsea boosting

A method for connecting coupling parts of a subsea coupling arrangement, the coupling parts having at least one sealing surface, in which the coupling parts are connected by displacing the coupling parts towards each other, wherein a watertight seal is formed when the coupling parts are connected, feeding filtered sea water through a channel into a space between the coupling parts during the displacement, flowing the filtered sea water over the sealing surfaces to prevent particles and dirt from being trapped between the sealing surfaces, and discharging the filtered sea water from the space into surroundings of the subsea coupling arrangement.

Method for connecting two coupling parts of a subsea coupling arrangement to each other

An arrangement related to subsea electric power distributing AC-system and adapted for a subsea application. The arrangement is enclosed in a watertight casing. The casing exposes a main power input connection, adapted for watertight co-ordination with a first subsea cable and a main power output connection, adapted for a watertight co-ordination with a second subsea cable. The second subsea cable is adapted for a power supply to an AC-current and AC-voltage adapted device. The arrangement includes interconnected: a voltage regulator connected to the first cable, and a NO-load switching unit connected to the second cable, and a control unit. The control unit is adapted, in a first operative mode, to regulate the output AC-voltage from the voltage regulator towards and to zero, or at least almost to zero, and in a second subsequent operative mode, to bring the NO-load switching unit from an ON-position to an OFF-position or vice versa.
