Subsea Toroidal Water Separator

A water separation system for use in well operations, the water separator comprising:

• a subsea production tree having a vertical passage with at least one laterally extending production branch;
• first and second upward-facing receptacles connected to the at least one laterally extending branch, the second upward-facing receptacle positioned opposite the first upward-facing receptacle;
• a subsea separation device having a hollow toroidal body, the toroidal body having an inlet on a first side portion thereof for admitting production fluid, and a less dense outlet for discharging less dense fluid and a more dense outlet for discharging more dense fluid located opposite the first side portion;
• an inlet tube extending from the inlet of the toroidal body that stabs into the first upward-facing receptacle to admit fluid therethrough when the separation device is mounted to the tree;
• and
• an outlet tube extending from the less dense outlet of the toroidal body that stabs into the second upward-facing receptacle to discharge fluid therethrough when the separation device is mounted to the tree.

A water separation system for use in well operations, the water separator comprising:

• a subsea production tree having a vertical passage with at least one laterally extending production branch, the tree having a mandrel on its upper end;
• a subsea separation device having a hollow toroidal body and a central mounting ring connected to the body by a central framework, the ring sliding over and being coupled to the mandrel such that the tree supports the entire weight of the subsea separation device, the toroidal body having an inlet on a first side portion thereof for admitting production fluid, and a less dense outlet for discharging less dense fluid and a more dense outlet for discharging more dense fluid located opposite the first side portion;
• first and second upward facing receptacles connected to the at least one laterally extending branch, the second upward-facing receptacle positioned opposite the first upward-facing receptacle;
• an inlet tube extending from the inlet of the toroidal body that stabs into the first upward-facing receptacle to admit fluid therethrough when the separation device is mounted to the tree;
• and
• an outlet tube extending from the less dense outlet of the toroidal body that stabs into the second upward-facing receptacle to discharge fluid therethrough when the separation device is mounted to the tree.
