A completion system and method for completing a subsea well with angular alignment-free assembly The system includes a series of circumferential channels formed in a well completion device at a boundary between a tubing hanger and the completion device. The circumferential channels provide complete circular fluid paths with respect to the tubing hanger and the completion device. A supply bore and a drain bore are in communication with each circumferential channel and oriented to supply a fluid to and remove fluid from, respectively, the circumferential channel. 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.
