Corrosion Resistant Heavy Duty Marine Transfer Hose with 10-21 Bar Pressure for

STS Hose is a heavy duty marine transfer hose engineered for ship-to-ship petroleum transfer, offshore bunkering operations, and large scale crude oil handling systems. The hose features a multi-layer reinforced architecture with high tensile synthetic fiber cord, steel wire helix reinforcement, and oil resistant nitrile rubber inner tube.

Designed to operate under high pressure conditions while maintaining structural stability in harsh offshore environments, the outer layer provides resistance against seawater corrosion, UV radiation, abrasion, and mechanical stress caused by vessel movement.

This hose delivers high performance fluid transfer capability, ensuring stable flow rate, pressure balance, and long service life. It is widely used in offshore energy logistics, port terminals, and marine engineering systems where safety and durability are critical.

A European offshore oil logistics company operating 100,000-150,000 DWT tanker fleets faced serious operational risks during ship-to-ship crude oil transfer in the North Sea. The previous hose system suffered from pressure fluctuation, cold weather cracking, and frequent leakage during high sea state operations.

Hongruntong Marine provided a customized STS Hose system with enhanced low temperature flexibility and reinforced pressure stability design. After installation, transfer efficiency increased by 29% due to stable internal flow control, emergency maintenance frequency reduced by 42%, cold weather cracking issues were completely eliminated, and offshore safety compliance significantly improved under marine inspection standards.

The client reported that the system performed consistently under sub-zero temperature conditions and high wave impact environments, proving long-term reliability in harsh offshore logistics operations.

Note: Various sizes can be customized according to the requirements.

• High-Pressure Multi-Layer Reinforcement Structure
  Constructed with textile cord reinforcement combined with steel wire helix layers. This structure distributes mechanical stress evenly, preventing localized deformation under pressure surges and ensuring stable operation during offshore pumping cycles with frequent hydraulic shocks.
• Hydrocarbon-Resistant Inner Tube System
  Engineered for compatibility with crude oil, diesel, gasoline, and aromatic hydrocarbons. Prevents swelling, cracking, and chemical degradation during long-term exposure, ensuring stable flow performance and reducing contamination risks.
• Marine Environmental Protection Outer Cover
  Designed to withstand seawater exposure, UV radiation, ozone aging, oil contamination, and mechanical abrasion. Ensures long-term durability in harsh offshore environments and prevents premature surface aging.
• Dynamic Fatigue Resistance Engineering Design
  Structure optimized for repeated bending cycles caused by vessel motion and wave impact. Reinforcement geometry reduces stress concentration, extending service life under continuous offshore dynamic loading conditions.

• Offshore Ship-to-Ship Crude Oil Transfer Operations
  Widely used in crude oil transfer between VLCC, Suezmax, and Aframax tankers in offshore anchorage zones. Ensures safe and stable operation under wave motion and vessel drift conditions.
