Marine Breakaway Couplings (MBC)

Hongruntong Marine provides high-performance Breakaway Couplings designed for offshore oil transfer systems, manufactured in full accordance with OCIMF 2009 standards. These couplings serve as critical safety devices in floating hose assemblies or SPM/STS operations, ensuring immediate shutoff and separation during over-tension or emergency disconnection scenarios.

We offer two main types to suit different operational preferences:

• Petal Type: Features a petal-shaped valve system that provides efficient sealing with minimal pressure drop, ideal for high-flow operations.

• Flip Flap Type: Employs a flap valve design for quick response and compact structure, suitable for space-restricted offshore systems.

Key Features & Benefits

• Automatic Breakaway Activation: Disconnects under dangerous tensile or surge conditions.

• Zero Spill Design: Dual shutoff valves instantly seal the system to prevent leakage.

• Corrosion & Marine-Grade Materials: Ensures durability in harsh offshore environments.

• Mechanical Operation: No external power required, fully fail-safe.

• Low Maintenance & Long Service Life

Applications

Breakaway couplings are widely used in:

• Single Point Mooring (SPM) systems

• Ship-to-ship (STS) oil transfer

• Offshore floating hose strings

• Crude oil and refined product transfer terminals
