A completion system, and a corresponding method, for completing a subsea well, where the well includes a wellhead and a tubing hanger disposed in the wellhead and supports a string of production tubing, allows for angular alignment-free assembly of the subsea well. The completion system includes a series of circumferential channels formed in a well completion device at a boundary between the tubing hanger and the well completion device. The circumferential channels provide complete circular fluid paths with respect to the tubing hanger and the well completion device. At least one supply bore is in communication with each circumferential channel and is and oriented to supply a fluid to the circumferential channel, and at least one drain bore in communication with each circumferential channel and is oriented to remove fluid from the circumferential channel. Finally a circumferential electrical connector couples the tubing hanger and the completion device. The circumferential channels and bores provide fluid services between the completion device and the tubing hanger and the electrical connector provides electrical services to the tubing hanger. The completion system allows the fluid and electrical services to be provided without requiring any angular alignment between the tubing hanger and the completion device.
