Hot Make Hot Break


The “HOT MAKE HOT BREAK” (HMHB) is a full-bore, pressure-balanced, zero spill “Quick Connect Disconnect” (QCDC) Coupling.

The HMHB provides a dedicated solution to High Pressure Subsea: Emergency Quick Disconnect (EQD) situations. The HMHB can be used for regular non-emergency operations.

The HMHB protects personnel, the environment and assets, without prolonged downtime.

The HMHB operates once an axial pull force is applied. The valve closure automatously seals and contains both the Fixed receptacle and the Free Probe. Providing zero spill and zero through seat leakage.

The HMHB facilitates the quickest connection (and reconnection) of any QCDC. The autonomous retention system aligns and retains the Coupling once attached and allows operations to re commence without delay.

The pressure balanced design removes any internal forces acting on the retention arms. This allows the connection and disconnection to be quick, safe without residual or full pressure transferring to the bore.

Re connecting the HMHB is “plug and play”. Only requiring the HMHB Probe to be introduced back to the receptacle. The valve closure autonomously opens, allowing operations to continue.

The HMHB is equipped with position indication (PI) to ensure the state of the connection is achieved.

The HMHB is designed to enable efficient pumping/transfer of fluids while providing a reliable safety system in the event of a vessel losing DP (dynamic positioning).

The HMHB can be positioned subsea or topside on non dedicated flanges. The HMHB will passively activate if the vessel it is connected to loses DP, even under full working pressure and with no fluid loss or line contamination, therefore delivering a high level of protection for crew, equipment and the environment.

The connector can be manually operated or overridden by ROV, diver, actuator or winch. It allows operators to dispense with guillotines and other uncontrolled subsea and topside emergency disconnection systems.

The ease with which the HMHB can be connected and disconnected also significantly reduces operational downtime and deferred oil revenues.
