The invention provides a system for subsea pressure booster HV (high voltage), MV (medium voltage) and LV (low voltage) power supply and distribution. The system is distinguished in that the system consists of, essentially consists of or comprises: a supply cable without a connected variable speed drive/variable frequency drive (VSD, VFD); at least one subsea pressure booster, and; one subsea direct online switch (SDOS) for each subsea pressure booster, wherein the supply cable at a source end is coupled to an AC power source at a topside, onshore or subsea location, wherein the supply cable at a pressure booster end is coupled directly or via a distribution device to at least one subsea direct online switch, SDOS, wherein each SDOS is coupled to one subsea pressure booster. Method of operation and use of the system.

System for subsea pressure booster power supply and distribution, method for operation and use thereof

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.
