Multipurpose Positive Displacement Pump

Hydraulically driven, designed to be powered by WROV auxiliary hydraulic power pack

Interface Engineering Solutions has developed and tested this cost efficient and reliable subsea pump to furnish a much needed resource to the pipeline decommissioning tool kit. It has a proven track record and has proven to be a workhorse.

Developed specifically for pipeline flushing operations involving high risk operations such as pumping of hydrocarbons.

It is interfaced, powered and controlled via the suitable work class ROV. All power and controls are transferred between the pump and ROV by subsea pressure balanced hot-stab. The unit may be wet stored on the seabed for extensive period of time.
