High-Performance Dry Disconnect Couplings


When you are transferring fluids in demanding marine and subsea environments, a simple connection point is not enough. You need an engineered solution that guarantees safety, protects the environment, and maximises your operational uptime.

Secc’s range of dry disconnect couplings provide the definitive solution for critical fluid transfer operations. Our field-proven and patented technologies are trusted by the world’s leading energy operators to deliver robust, safe, and efficient performance without compromise.

Eliminate Spills and Enhance Safety with Zero-Leak Technology

Preventing fluid loss during connection and disconnection is fundamental to safe and responsible operations. Protecting your personnel from hazardous media, avoiding environmental pollution, and eliminating costly clean-ups are critical priorities.

That’s why Secc’s couplings are engineered for proven Zero-Spill and Zero-Leak performance. Through our advanced and patented probe and sleeve sealing technology, we provide true zero-spill connections that safeguard your people, assets, and the environment. With over 20 years of field-proven performance across a wide range of demanding applications, our technology delivers reliability you can depend on.

Hot Make Hot Break (HMHB) QCDC

The Hot Make Hot Break (HMHB) is the ultimate Quick Connect Disconnect Coupling (QCDC). It offers true “plug-and-play” capability, allowing for rapid and repeatable connections that can be operated by ROV or personnel without needing specialist tools or equipment. This significantly reduces downtime and improves your operational efficiency.

Midline Weak Link (MLWL)

The Midline Weak Link (MLWL) is the ideal passive safety solution when protecting flexible hoses. It acts as a safety “fuse” in your line, designed to protect hoses and infrastructure from damage caused by over-tensioning. In the event of a vessel drift-off, it provides a clean, zero-leak breakaway at a pre-set load with the fastest and simplest resetting.

MAXFLOW Midline Weak Link (MFML)

The MAXFLOW Midline (MLWL) is the ideal cost-effective midline passive breakaway coupling when connecting two flexible hoses with negligible pressure drop thanks to the straight uninterrupted full bore. Pressure Balanced allowing high pressure and low break loads. Designed for applications where spill is permitted (non-valved).

HIGHFLOW Emergency Release Couplings (HF-ERC)

Designed for large-bore marine fluid transfer, our HIGHFLOW Emergency Release Couplings (HF-ERC) are the ultimate solution for  high volume and high velocity fluid transfer. The robust, full-bore design ensures maximum flow rates while providing zero-spill and zero-leak protection for high-volume transfers of hydrocarbons, such as Crude Oil, LPG and LNG.

ECOFLOW+ Hot Stabs

For static and low-flow hydraulic applications and temporary, or semi-permanent, subsea connections, the ECOFLOW Hot Stab is the definitive choice. Its patented zero-spill valving is engineered to prevent hydraulic fluid from contaminating the environment or sensitive subsea equipment during connection and disconnection.  ECOFLOW+ is fully serviceable, with simple maintenance procedures which require no special tooling.

Our Range of Dry Disconnect & Breakaway Couplings

Secc offers a comprehensive portfolio of dry disconnect couplings designed to meet the specific demands of your application. From passive breakaway safety systems to fully operable Quick Connect Disconnect Coupling (QCDC) systems, we have a solution to enhance your fluid transfer operations.

The Secc Advantage: Patented Technology for Unrivalled Performance

Secc is an IP-led engineering company that proactively identifies and solves the inherent weaknesses of conventional connectors. Our patented design features deliver unmatched operational and safety benefits for your critical projects.

  • Pressure-Balanced Design: Unlike other couplings, our technology eliminates the dangerous separation forces caused by internal pressure. This unique design ensures a safe, controlled release at any pressure without the violent piston effect that can damage equipment and endanger personnel.
  • Full-Bore Flow Path: A completely unobstructed flow path means you achieve maximum flow rates with minimal pressure drop. This trim-less design is also ideal for handling dense and abrasive fluids such as crude oil, cement and drilling muds without risking damage to internal components.
  • Integrated Fail-Safe Operation: The valve closure mechanism is mechanically interlocked with the release system. This makes it impossible to activate the coupling with an open valve, a critical fail-safe that simplifies controls and enhances operational safety.
  • Rapid Resetting & Servicing: Downtime is costly. Our couplings are derived from QCDC principles, allowing them to be reset in minutes, not hours or days. This drastically reduces downtime and allows your operations to resume swiftly.

Applications in Demanding Industries

Our advanced dry disconnect couplings are trusted to deliver superior performance and safety across key industrial sectors.

  • Marine Transfer: Ensuring the safe and efficient transfer of hydrocarbons with our robust HIGHFLOW ERCs, protecting your assets and the environment.
  • Subsea Well Intervention: Enabling high-pressure, high-rate fluid transfer for Intervention, well enhancement, workover, and P&A tasks with our field-proven HMHB and MLWL couplings.
  • Decommissioning & P&A: Reliably handling abrasive fluids like cement and providing fail-safe breakaway protection for vessels and critical subsea infrastructure.
  • Industrial & Cryogenic Transfer: Offering versatile, zero-drip, and low-temperature compatible solutions for transferring a wide range of hazardous or sensitive fluids.
