Flint Subsea EQD Skid Upgraded

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 sea bed during operations. The system is modular, meaning that additional valves and gauges can be added and removed with minimal effort and time. 2” Hot Stabs (male and female) are also included in the package.

Gareth Black, Flint Subsea Technical Director commented that “this addition to the EQD skid provides our clients with an added layer of protection on top of the EQD connectors and ROV operated valves, which are already incorporated onto the skid. We have responded to market demand to enhance the package for direct well pumping works.  

For more information, please view the EQD data sheet.

Flint Subsea Invest in Fleet

Flint Subsea have demonstrated commitment to their clients by adding additional 2” and 4” EQDs to their fleet. This significant investment is on the back of increased demand for their EQD products to mitigate against excess hose tension and prevent injury to personnel, the environment or infrastructure. These devices can be installed top side or subsea and can be supplied with a range of standard accessories such as remote disconnect capability or hang off collars.

Flint Subsea’s technical director, Gareth Black said, “these devices represent the simplest method to protect the environment without placing personnel into the firing line through the use of hammers or guillotines and without additional infrastructure”. He added, “they are easy to install into hose strings and are available with a range of end connections including flanges, hammer unions and screwed”.

The new EQD units are available immediately to serve clients in global locations. 

Flint Subsea Invest in Fleet

Flint Subsea will be exhibiting at AOG in Perth, Western Australia from March 13th to March 15th 2019. We have our own booth, location B17, conveniently close to Andy's Bratwurst Bar! During the show, we will be showing our range of Emergency Quick Disconnect solutions.

4" Emergency Quick Disconnect

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 operation effective and safe. 

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

Flint Subsea & Marine connectors sit anywhere along the hose string, donline 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 2” EQD (340bar and 690bar) versions widely used on global projects.
