Flint Subsea Limited have upgraded their Emergency Quick Disconnect (EQD) skid to include a fail-close actuator on the system’s main isolation valve. This new development now provides emergency full system shut down capability in an ‘event’ to isolate the well during direct well pumping operations.
In a drift off or disconnect scenario, the EQD skid will automatically shut off, retaining system pressure and preventing excessive discharge to the marine environment. Used in conjunction with the Flint Subsea Mid-Line EQD Breakaway connectors, full system integrity is assured during a pull-off event.
Utilised for subsea pumping operations the skid has been deployed in the North Sea and West Africa for decommissioning, pipeline testing and well injection projects.
The Flint Subsea EQD skid incorporates a 2” through bore, rated to 10000psi and is suitable for most well bore and stimulation fluids. It also incorporates a clump weight, which can be adjusted between 2 tonnes and 6 tonnes, ensuring that it is not pulled off the seabed during operations. The system is modular, meaning that additional valves and gauges can be added and removed with minimal effort and time.
