Landmark: First FMC Technologies frame agreement in U.K. Sector

The maximum-function EHXT is designed to be installed in any of the U.K. North Sea fields. The tree-mounted direct-hydraulic controls allow the tree to be interfaced with different types and suppliers of control systems based on a "plug and play" system using hydraulic and electrical jumper umbilicals with the appropriate connectors that interface with tree-mounted controls This system allows the tree design to be standardized and provide the flexibility to be installed in brown and green fields. The integral fishing-friendly structure (FFS) is the only protective structure approved by the Scottish Fisheries Federation and allows the tree assembly to be installed through a standard moon pool 361 ft2 (36 m2), eliminating the need for a special installation.
