Subsea Workover, Completion, Intervention & Abandonment Support Equipment

InterAct’s subsea support equipment provides operators with the ability to control seafloor wells from the back of a boat or the surface of a jack-up rig. The InterAct Intervention / Workover Control System (IWOCS) includes a surface control unit, hydraulic power unit, hose sheave, subsea connectors and subsea control pod.

How It Works

Pressurized hydraulic fluid from the pumps is sent through the surface control unit control valves. The pressurized fluid then goes through the hose bundle and is directed to the subsea control pod. The pilot valves in the subsea control pod direct the fluid to the tree valve actuators. These systems can be adapted to any fluid type requested by our customers. The system hoses are installed by a team of divers.

  • Hydraulic Power Unit capable operating at low pressure 3,000 psi (207 Bar) and high pressure 10,000 psi (690 Bar), with 13 function control panel and 5,000 psi and 10,000 psi accumulators
  • 13 function control panel 500’ of umbilical with 12 lines rated at 3,000 psig working pressure (WP) and one line rated at 10,000 psig WP
