4” Emergency Quick Disconnect for Flint Subsea
Tuesday, Apr 10, 2018


Flint Subsea & Marine have designed and manufactured a unique 4” midline emergency quick disconnect (EQD) system rated for working pressures over 100 bar for its service and vessel operating clients.  The connector is fully pressure balanced with a straight through and unobstructed bore which self seals on disconnect.

The 4” EQD connector is a major break through of technology where Flint Subsea have been able to combine a pressure balanced self sealing EQD with a low weight and size and high flow rate capacity.  The result means there are no pressure separation forces on the device thus simplifying the EQD operation, removing fatigue from the pins and the need to set them according to pressure and depth. Additional features incl remote actuation and tie back capability are built into the design.

Flint Subsea & Marine are specialists in the design and manufacture of EQD connectors and systems for both topside and subsea projects.  Having been operating in the EQD market since 2008 we understand project challenges and the EQD tools necessary to make operations effective and safe.

The addition of the 4” to the EQD family means service companies can reliably pump higher flow rates and increased pressures with a device that can be easily handled by offshore personnel.

Flint Subsea & Marine connectors sit anywhere along the hose string, downline subsea or mounted on the vessel / platform and are designed to breakaway and self seal in an emergency situation. The 4”, having been in operation during 2017, compliments the existing Flint Subsea 2” EQD (340bar and 690bar) versions widely used on global projects.
