Comments
The maximum function enhanced horizontal tree is desogned to be installed in any of the CNR fields in the central north sea. 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 approriate connectors that interface with tree mounted controls. This system allows the tree design to be standardized and provide the felxibility to be installed in brown and green fileds.
The integral fishing friendly structure (FFS) is the only protective structure approved by the Scottish Fisheries Federation and allows the tree assembly to be iinstalled through a standard moon pool 6 meters x 6 meters eliminating the need for a special installation vessels.
