Engineered for the Field: The Versatility of HYSF Split-Series Subsea Connectors

Split-series subsea connectors are specialized underwater interfaces featuring a two-piece clamping sleeve design. They are used to facilitate quick assembly and disassembly without specialized tools, making them ideal for field maintenance. These connectors offer superior vibration resistance and 360-degree locking strength compared to standard threaded versions. HYSF Split-Series connectors are pressure-rated up to 60MPa and are available in 316SS and Titanium for ROV, AUV, and sensor applications.

In the demanding world of subsea exploration and offshore energy, time is more than just a metric—it is the most significant cost factor. When critical equipment requires maintenance on a moving vessel or reconfiguration in a confined subsea workshop, the limitations of standard threaded connectors become apparent. Struggling with specialized tools or seized threads can lead to hours of expensive downtime. To address these challenges, HYSF SUBSEA has engineered the Split-Series Connector, a modular solution designed for rapid deployment and ultimate mechanical reliability.

The defining feature of the Split-Series is its unique two-piece clamping sleeve mechanism. Unlike traditional connectors that rely on a single rotating nut, the split-series utilizes a precision-machined collar that “sandwiches” the connection. This design provides several transformative advantages for ROV (Remotely Operated Vehicle) operators and marine engineers.

1. Tool-Free Efficiency and Rapid Maintenance The primary engineering goal of the Split-Series is the elimination of complex assembly procedures. The clamping design allows technicians to assemble or disassemble the connection manually or with basic hand tools. This “Quick-Swap” capability is vital for modular subsea systems where sensors, cameras, or thrusters need to be replaced frequently in the field.

2. Superior Locking Under High Vibration Standard threaded connectors can occasionally suffer from “backing out” due to the constant vibrations of ROV thrusters or heavy current flow. HYSF’s split-clamping sleeve provides 360-degree uniform compression across the mating surface. This high-friction engagement ensures that the connector remains securely locked even under extreme mechanical stress or cable tension, providing peace of mind during long-term deployments.

3. Material Excellence and Deep-Sea Integrity Despite its focus on ease of use, the Split-Series does not compromise on environmental resistance. HYSF offers these connectors in Нержавеющая сталь 316L for standard maritime use, and Grade 5 Titanium for deep-ocean missions where weight reduction and absolute corrosion immunity are required. Combined with our high-performance O-ring seals, the series is rated for pressures up to 60MPa (6000 meters depth).

4. Bespoke Internal Configurations The Split-Series housing is designed to be versatile. We can customize the internal inserts to handle high-speed Ethernet, high-voltage power, or hybrid fiber-optic configurations. By combining the “Mixed Pin & Socket” customization with the split-sleeve exterior, HYSF provides a connection that is both electrically sophisticated and mechanically robust.

Whether you are managing an offshore fleet or developing a bespoke autonomous underwater vehicle (AUV), the HYSF Split-Series represents the next evolution in subsea interconnect technology—where speed meets security.


Question: What are split-series subsea connectors and why are they used?

Answer: Split-series subsea connectors are specialized underwater interfaces featuring a two-piece clamping sleeve design. They are used to facilitate quick assembly and disassembly without specialized tools, making them ideal for field maintenance. These connectors offer superior vibration resistance and 360-degree locking strength compared to standard threaded versions. HYSF Split-Series connectors are pressure-rated up to 60 МПа and are available in 316SS and Titanium for ROV, AUV, and sensor applications.


Frequently Asked Questions (FAQ)

Q1: How does the split-sleeve prevent accidental disconnection? Answer: The split-sleeve is designed to provide uniform radial pressure around the connector body. Once the outer locking ring is secured, the mechanical friction across the large surface area prevents the connector from loosening, even when subjected to the high-frequency vibrations common in work-class ROVs.

Q2: Can the Split-Series be used for hybrid data and power links? Answer: Yes. The internal architecture of our split-series housings can be customized to accommodate various core counts and types, including 8-pin Ethernet, high-current power pins, or high-bandwidth fiber optics.

Q3: Is this series compatible with existing M10/M14/M16 bulkhead holes? Answer: Absolutely. HYSF can customize the thread size and mounting interface of the split-series bulkhead to ensure a “drop-in” fit for your existing pressure vessels, allowing you to upgrade to the split-series system without redesigning your hardware.
