A submersible well fluid system for operating submerged in a body of water may include an electric machine and a fluid end. The electric machine includes a rotor and a stator residing in a first housing at specified conditions. The fluid end may include an impeller and be coupled to the electric machine. The submersible well fluid system may also include an adjustable speed drive for the electric machine in the housing. The submersible well fluid system may also include a chemical distribution system for supplying treatment chemicals to the submersible well fluid system, a barrier fluid supply system for supplying a barrier fluid to the submersible well fluid system, and a pressure management system.

Submersible well fluid system

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 system for the recirculation of gas in air gaps of rotating machines via an ejector, a motor and a pump, including circulating a gas extracted from a gas-extraction unit which is located in the pump. This gas circulates in the gap between the rotors and the stator of the motor. The rotor of the motor is coupled to the shaft of the pump, and in one or more embodiments the gas from the gas-extraction unit flows from the pump to the ejector in order to be injected into the air gap between the rotor and the stator, thereafter returning to a process line. In one or more embodiments, the gas from the gas-extraction unit flows from the pump, and is injected directly into the air gap, and thereafter passes via the ejector in order to recirculate the gas to the process line.
