Gas bunkering plays a critical role in the global energy transition, but it presents unique challenges. Handling lighter fuels and chemicals such as LNG, Ammonia, and Hydrogen demands the highest standards of safety and performance. Especially when it comes to minimizing the risk of spills during a controlled breakaway.
Secc is a trusted provider of advanced Emergency Release Couplings (ERCs), engineered specifically to meet the demands of modern gas bunkering applications. Our solutions enable operators to conduct bunkering operations with maximum safety, protecting personnel, assets, and the environment.
Secc’s HIGHFLOW Emergency Release Coupling (HF-ERC) serves as a fail-safe breakaway system, engineered for the emergency disconnection of cryogenic and hazardous liquid transfers. It provides instantaneous and controlled separation when it matters most, helping to protect personnel, assets, and the environment.
The HF-ERC features the smallest internal volume between valve closures of any full-bore ERC on the market. Combined with Secc’s patent-pending vent feature, it delivers true zero-spill and zero-leak performance during activation.
This innovative design minimises product loss, reduces environmental impact, and ensures compliance with the most stringent safety and regulatory standards, giving operators complete confidence in every transfer.

Secc’s patented technology is engineered to overcome the specific safety and operational challenges of bunkering next-generation marine fuels.
When transferring volatile liquids like LNG, even a small spill can expand into a large, hazardous gas cloud. The HF-ERC’s zero spill and zero leak design provides the highest level of containment, protecting your crew, assets, and the environment from flammable or toxic vapours.
Our couplings are purpose-built to perform reliably in low-temperature environments. With proven seal technology and robust materials, the HF-ERC ensures operational integrity and safety when transferring fuels like LNG and ammonia.
The full-bore design is completely free of internal obstructions, allowing for the fastest possible transfer rates with minimal pressure drop. This helps you minimise the duration of the bunkering operation, reducing on-site risk and improving vessel turnaround times.
Our unique pressure-balanced design eliminates the dangerous thrust generated by internal pressure during an emergency breakaway. This guarantees a safe, controlled separation, preventing violent ejections that could damage equipment or endanger personnel.
