1. Safety & Compliance First
Safety is critical in marine fuel transfer operations.
Our hoses are designed, tested, and certified according to OCIMF 2009 and EN 1765 standards — ensuring:
Burst resistance > 4× working pressure
Full electrical continuity (anti-static lining)
Leak-proof double reinforcement
Explosion-proof couplings & end fittings
All hoses are tested before shipment with hydrostatic and electrical tests, and test certificates are provided upon request.
2. Low Maintenance, High Reliability
We understand downtime is costly.
Our marine hoses are built for extended service with:
Anti-aging rubber compounds for UV and saltwater resistance
Flexible structure preventing kinking and fatigue cracking
Smooth inner wall reducing friction and pressure drop
Average maintenance cost reduced by up to 30% compared to standard fuel hoses.
3. Compatibility with Marine Systems
Each hose is engineered for seamless integration into shipboard and port systems:
Compatible with all major coupling systems (Camlock, ANSI, DIN, JIS)
Works with floating or fixed installations
Optional flange or nipple ends for customized interfaces
Suitable for crude oil, diesel, gasoline, jet fuel, and other petroleum products
4. Service, Support & Customization
We don’t just sell hoses — we provide complete transfer solutions:
Custom lengths, diameters, and pressure ratings
Engineering support for STS & dock layouts
Fast production lead time (2–4 weeks typical)
Global delivery with pre-inspection and certification
Lifetime technical support and replacement services

Applications & Real Use Cases
Tanker Cargo Transfer — High-pressure hoses for ship-to-shore loading
Bunkering Services — Fuel delivery to ships at anchor or berth
Oil Transfer at Sea (STS) — Floating hoses bridging vessels
Offshore Platforms — Fuel & utility transfer in marine environment
Case Example: Our STS hoses used in offshore oil terminal reduced fuel spillage incidents by 60% over 3 years.
Frequently Asked Questions (FAQ)
Q1: How do I choose between STS, Cargo, and Bunkering hoses?
A: Use Cargo hoses for ship-to-shore oil transfer, Bunkering for dock fueling, and STS hoses for floating ship-to-ship operations.
Q2: How often should marine hoses be inspected?
A: Perform visual checks before each use and full testing every 12 months to meet OCIMF requirements.
Q3: Can the hoses be customized for extreme temperatures?
A: Yes — we can provide EPDM or special compound rubber for –30 °C environments.
Q4: What kind of couplings can be fitted?
A: Flanged, threaded, or camlock types compatible with ANSI, JIS, or DIN standards.
Q5: What’s the expected lifespan of your hoses?
A: 8–12 years depending on operation and maintenance.
Q6: What pressure rating should I choose for cargo oil hose?
A: It depends on your flow rate and safety margin — typically choose a hose rated at least 1.5× expected working pressure.
Q7: Can STS hoses float?
A: Yes — we offer floating designs that maintain buoyancy and minimize drag during transfers.
Q8: Do marine hoses degrade in saltwater / UV?
A: Not if they use marine-grade rubber compounds and protective outer layers — Hongruntong hoses are formulated for such exposure.
Q9: How long is the service life?
A: Typically 8–12 years under normal marine operation, depending on usage and maintenance.
Q10: Are your hoses certified?
A: Yes — compliance with OCIMF, EN 1765 and internal test reports provided.
