A subsea variable speed drive apparatus comprising a pressure resistant container () comprising a curved wall section having a curved, internal surface (); and a variable speed drive comprising at least one power electronics module () arranged inside the container and held at a predetermined ambient pressure. The at least one power electronics module is mounted on a heatsink () which is mounted on the internal surface, the heatsink comprising a curved surface () contacting the internal surface and having a radius of curvature corresponding to the radius of curvature of the internal surface. A subsea hydrocarbon fluid pumping system comprising such subsea variable speed drive apparatuses and a related method are also disclosed.

Subsea variable speed drive apparatus

A subsea power distribution device and system. The subsea power distribution device comprises a watertight housing accommodating at least one transformer, the transformer having a primary winding and a plurality of secondary windings; input terminals, electrically connected to the primary winding and arranged to be connected to a remote power supply; output terminals, electrically connected to the secondary windings and arranged to be connected to subsea power consuming devices. The switches are arranged to break the connections between each secondary winding and a corresponding output terminal, and the switches are arranged within the watertight housing.
