Abstract:
A technique facilitates control of subsea equipment by providing a modular electro-hydraulic control system which can be used with various types of subsea equipment. The modular system is constructed to accommodate high axial loading while also withstanding high bending forces. Additionally, the components of the modular system are constructed and arranged to enable the modular system to fit through a rotary table of a rig. Depending on the parameters of a given application, the modular control system may be utilized for open water operations and in-riser operations.

Abstract:
A technique facilitates pressure testing of seals along a tubing hanger, such as a tubing hanger used in a subsea application. In some applications, the tubing hanger is sealed along its exterior with an upper tubing hanger seal and a lower tubing hanger seal. A valve assembly is deployed along a fluid passageway which is routed to the tubing hanger seals. The valve assembly may be selectively actuated to a test position, e.g. a closed position, which enables pressure isolation and pressure testing of the tubing hanger seals. The valve assembly may also be selectively utilized to introduce fluids into the formation below the tubing hanger.
