A subsea variable speed drive apparatus comprising a pressure resistant container (90) comprising a curved wall section having a curved, internal surface (90a); and a variable speed drive comprising at least one power electronics module (50) arranged inside the container and held at a predetermined ambient pressure. The at least one power electronics module is mounted on a heatsink (40) which is mounted on the internal surface, the heatsink comprising a curved surface (40b) 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.
A subsea variable speed drive apparatus comprising:
A method of producing a subsea variable speed drive apparatus comprising a pressure resistant container configured to hold atmospheric pressure, the 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, the method comprising the steps of:
