The SubComm is a modular subsea system designed to support a wide range of subsea pumping operations.

Operational flexibility through modular design

The SubComm system is a modular subsea system designed to support a wide range of subsea pumping operations.

The system is built around a 25ft frame with four module slots, which can be configured with a Power and Control Unit (PCU) and interchangeable reservoir modules. Working together, these components provide the fluids required directly at the work location, providing the shortest possible path between pumping system and injection point.

As well as reducing both fluid demand and response time compared to conventional equipment, the SubComm system reduces deck space demand and may significantly reduce schedule dependencies.

Designed for low pressure/high flow and high pressure/ low flow pumping that delivers reliable performance in demanding subsea environments. The unit is fully ROV-operated via EFL and HFL and eliminates the need for downlines and break-away connectors.

Pump and valve functions are controlled from a laptop through an intuitive graphical user interface. The software provides real-time logging and graphical visualization of key operating parameters, including pressure, flow rate, volume, and chemical dosing.

The system is compatible with a wide range of fluids. Fluid compatibility can be assessed on request.
