OUR SERVICES
What can we do
for you?
From 6,000-meter deep-sea exploration to complex offshore energy projects, HYSF engineers high-performance underwater connection solutions tailored to your exact needs. We don’t just manufacture connectors; we provide a full-spectrum OEM/ODM service
Custom Engineering & OEM/ODM Services
HYSF specializes in transforming complex subsea challenges into reliable connection realities. From conceptual sketches to mass production, we offer comprehensive OEM/ODM services to meet the most demanding non-standard specifications for ROV, AUV, and offshore instrumentation.
- Tailored Electrical Parameters: Customize your connection with precise voltage and current ratings (up to 180A/800V) and contact configurations ranging from 2 to 48 cores.
- Flexible Thread & Mounting Styles: Support for a wide array of thread standards including UNF, Metric, and NPT, available in Bulkhead, Flange, or L-shaped orientations.
- Rapid Prototyping & Sampling: Accelerated design-to-prototype cycles to support your R&D phase, ensuring quick validation before large-scale deployment.
- Proprietary Branding (OEM): Private labeling and custom aesthetic designs that integrate seamlessly with your brand’s product line and technical ecosystem.
Specialized Underwater Cable Assemblies
Our cable solutions are engineered for more than just power transmission; they are designed for performance and survivability. We provide specialized cabling that ensures structural integrity and signal stability in the most dynamic marine environments.
- Zero-Buoyancy Innovation: Specialized neutral-buoyancy cables designed specifically for ROVs and AUVs to prevent tether drag and improve underwater maneuverability.
- Dynamic Spring & Coiled Cables: Retractable coiled cable solutions for robotic arms and sensor arrays that require repeated extension and contraction without fatigue.
- Harsh-Environment Jacket Materials: High-performance insulation using PUR, Neoprene, or FEP to resist chemical corrosion, UV exposure, and long-term seawater immersion.
- Custom Lengths & Terminations: Precision-cut cable lengths with factory-molded terminations, ensuring a 100% watertight seal and superior strain relief.
Advanced Material & Deep-Sea Testing
Reliability in the deep ocean is defined by material science. HYSF utilizes premium aerospace-grade and marine-grade materials to ensure your equipment survives the crushing pressures and corrosive nature of the abyss.
- Titanium & 316L Stainless Steel: High-strength housing options including Grade 5 Titanium for weight-sensitive missions and 316L Stainless Steel for rugged durability.
- 6,000M Depth Rating (60MPa): All customized components are engineered and validated to withstand extreme hydrostatic pressures up to 60MPa (6,000 meters depth).
- Enhanced Corrosion Resistance: Advanced surface treatments including hard anodizing for aluminum alloys and specialized coatings for long-term subsea deployment.
- Rigorous Pressure Validation: Every custom project undergoes mandatory simulated deep-sea pressure testing and insulation resistance checks before shipment
Subsea Integrated Systems & Enclosures
HYSF provides higher-level integration services beyond the connector level. We design and build integrated subsea hardware that protects your critical electronics and simplifies complex underwater system architectures.
- Custom Pressure Vessels (Dry Cabins): Bespoke design and fabrication of underwater enclosures to house sensors, batteries, and control circuitries at extreme depths.
- Integrated Junction Boxes: Complete PBOF (Pressure Balanced Oil Filled) systems and distribution boxes to streamline power and data routing for sensor arrays.
- Hybrid Connectivity Solutions: Integration of Ethernet, Coaxial, and Power contacts into a single compact interface to reduce the footprint on your underwater vehicle.
- Full System Assembly: Professional integration of connectors, cables, and penetrators into your existing hardware, providing a "plug-and-play" subsea solution.
