Bunkering operations, which involve transferring fuel or liquids between ships and storage facilities, demand stringent safety measures to prevent environmental damage. Breakaway Couplings, particularly the Flip-Flap Type, ensure high flow rates and automatically separate during excessive tension, preventing spills.
The Role of Breakaway Couplings in Bunkering
Breakaway couplings prevent hose rupture and fuel spills during emergencies like ship drifts or accidental pulling. The Flip-Flap Type excels in maintaining superior flow rates and ensures safe, spill-free disconnections, enhancing operational safety and environmental compliance. However, breakaway couplings are not always mandated for hose-based ship-to-shore transfers, unlike Emergency Release Couplings (ERCs), which are required for marine loading arms. This disparity creates a gap in safety standards, leaving hose-based operations more vulnerable to risks.
The Consequences of Not Using Breakaway Couplings
In the absence of breakaway couplings, emergencies like fires, storms, or sudden ship movements can lead to catastrophic consequences. A ship pulling away could rupture hoses, cause significant fuel spills, and result in environmental damage, high cleanup costs, and potential harm to personnel. Conversely, if breakaway couplings are installed, they activate when tension is detected, preventing spills and allowing the ship to drift safely. The liquid contained in the hose remains secure, making the operation far safer for both human personnel and the environment.
Typical Breakaway Coupling Arrangement
Typically, breakaway couplings are installed between the jetty manifold and the hose. In normal operations, the coupling acts as part of the manifold. However, in emergencies, it mechanically activates to prevent spillage and damage. This setup ensures a secure connection during normal transfers while providing immediate response capability when needed.
Conclusion
Installing Flip-Flap Type Breakaway Couplings in bunkering operations is crucial for preventing spills, ensuring operational efficiency, and maintaining safety. While ERCs are required for marine loading arms, breakaway couplings should also be adopted for hose transfers to safeguard the environment, reduce operational costs, and enhance overall safety during ship-to-shore fuel transfers. These couplings are an essential component for improving the safety and sustainability of bunkering operations across ports, jetties, and shipping companies.
