Abstract: A subsea wellhead assembly having a tubing hanger set in a tubing hanger spool and a ring with axial passages set in an upper end of the tubing hanger. The wellhead assembly includes a production tree that lands on the tubing hanger spool. Tubing extends from the axial passages in the ring through axial bores provided in a sidewall of the tubing hanger. When landed, a lower end of the production tree engages an upper surface of the ring causing the ring to rotate and align its axial passages with axial passages in the production tree. The respective lower and upper surfaces of the tree and ring are strategically castellated to orient the passages.

Abstract: A subsea well apparatus has features for controlling and monitoring production fluid flow from a well. A christmas tree lands on a subsea wellhead, the tree having a tubular, open upper end. A first flow passage extends from a lower end of the tree to the upper end for communicating fluid with the well. A second flow passage extends downward from the upper end of the tree and has an outlet on a sidewall of the tree for communicating with a flowline. A production module lands on and is retrievable from the upper end of the tree, the module having a flow loop with one end in communication with the first flow passage and another end in communication with the second flow passage. At least one flow interface device is located in the loop of the production module. The flow interface device may be used to monitor or control the flow and may be a temperature or pressure sensor, a flow or multi-phase flow meter, or a choke.
