FMC Technologies has developed their new Enhanced Vertical Deepwater Tree (EVDT) for global applications. Based upon the widely field proven 10K Vertical tree and 15K HPHT Tree, and in response to a growing worldwide demand for reduced Total Life Cost, FMC has incorprated the latest technological advancements in the EVDT System.
- Allows for up to eleven (11) downhole functions – typically allocated as nine (9) hydraulic, and two (2) electrical or fiber optic lines
- 10,000 psi working pressure, fully rated to 10,000 ft (3,000 m) water depths
- -50 to 250 degree Fahrenheit (-45 to 121 deg C ) temperature range and may also be provided up to 350 degrees Fahrenheit (176 deg C)
- FMC’s proven Flow Module downstream of the wing valve
- Low tree weight of less than 82,000 pounds (37,200 kg) with the flow module in place and below 72,000 pounds (32,660 kg) with the flow module removed, the low weight EVDT is perfectly suited for production from lower cost, less capable rigs
- BOP-on-Tree interface

FMC’s proven Flow Module downstream of the wing valve. The flow module provides maximum flexibility and allows the tree to become standard regardless of application. The flow module can be configured to project specific variances such as production vs. water injection service, potentially eliminating the need for spare tree systems. The flow module can also be configured to include multi-phase flow meters, sensors, gauges, and supplies the tie-in point for future advances in subsea boosting and gas compression technologies. This allows an upgrade subsea without having to pull and re-run the entire tree system.
- Featuring a 13 5/8 inch O.D. slimbore tubing hanger with associated compact installation equipment, the EVDT system makes a perfect candidate for applications where a surface BOP compatible rig is being considered.
- The ability for the tubing hanger to either be installed directly in the subsea wellhead or in a tubing head spool. The in-wellhead completion compliments the new FMC 13 5/8 inch UWD-15 Slimbore Wellhead. The in-wellhead installation coupled with the slimbore tubing hanger and slimbore wellhead permits a well to be drilled and completed without having to pull the subsea BOP back to the surface to install either the tubing spool or horizontal tree spool.

Common and flexible interfaces play a major role in the EVDT system. A BOP-on-Tree interface allows the EVDT to be run either as a traditional vertical tree system with an open water completion riser, or like a horizontal tree system with the subsea BOP and landing string. This flexibility means an open water riser is now an optional piece of equipment which may be purchased or rented for larger projects where economics make it attractive. In conjunction, FMC has also developed a complimentary open water riser system specifically for the EVDT.
These features have not only allowed FMC to hit the mark regarding what the industry needs today, we have also allowed the system to accommodate technologies that will arise in the years to come.
