Subsea Test Pump

STP – Subsea Test Pump for performing pipeline hydro or leak testing without the use of downlines.



  • The STP can be mounted on an ROV skid or fitted to the Subsea Test Pump Manifold.
  • If the pump is mounted on a skid fitted below, or backpack on the ROV, it can be directly coupled to the main ROV hydraulic system thereby maximising the power available from the ROV, which improves the pump output performance & efficiency. Flow / press characteristics indicated below are for a typical ROV auxiliary pump supply.
  • Different flow rates can be selected via ROV operated pilot valves. Two independent pressure relief valves protect asset from over pressurisation.
