The increasing desire to develop marginal oil fields located in areas where extreme weather conditions prevail led to the use of high pressure flexible risers and umbilical control lines – hence a need for connection/disconnection devices between subsea well-heads and production platforms. MIB has supplied many custom-designed, high pressure flexible riser coupler systems for production, injection and control umbilical lines on floating systems world-wide. Based on the well-proven MIB integrated coupler and ball valve design, these systems offer minimal spillage, high angular release, extended maintenance-free periods and long service life installed at the deck or turret level, or subsurface on FPV pontoon, shut off and disconnection of the flexible risers is provided under normal or emergency conditions. Reconnection is also a diverless operation.

The key features of the QCDC systems are:

• Fast Hook-up

• Emergency Release

• Integral Ball Valves

• Single/Multiline

• 25 years design life

• High Angular Release

• Field Proven Design

• Pressure up to 10000 psi

• Sweet and Sour Service

• Minimal Maintenance

• ESD Valving
