Cold-Resistant Abrasion Resistant STS Hose for Oil Transfer with 10-21 Bar

STS Hose is a cold-resistant marine Ship-to-Ship transfer hose designed for offshore operations in low-temperature and Arctic-class environments. Engineered with a flexible synthetic rubber inner tube formulated to maintain elasticity under sub-zero conditions, it combines high-tensile textile reinforcement layers and a steel wire helix structure that ensures dimensional stability during both suction and discharge operations.

The outer cover uses weather-resistant marine elastomer compounds to protect against seawater, ice abrasion, UV exposure, and long-term thermal cycling. This hose is specifically developed for cold-region offshore logistics where conventional hoses often fail due to stiffening, cracking, or loss of flexibility.

A North Sea offshore supply operator faced serious operational delays during winter fuel transfer operations between supply vessels and offshore platforms. Standard hoses became rigid at low temperatures, increasing handling difficulty and causing delayed connection times during bunkering operations.

After switching to Hongruntong Marine cold-resistant STS Hose, the operator achieved stable flexibility even under sub-zero conditions. Hose handling time was significantly reduced, and coupling alignment became safer and faster. Over a full winter operational cycle, fuel transfer efficiency improved by 24%, while deck handling incidents related to hose stiffness were eliminated.

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

• Low-Temperature Elasticity Rubber System: The inner tube is formulated with specialized elastomer compounds designed to maintain flexibility at extremely low temperatures, preventing hardening, cracking, and loss of elasticity.
• Anti-Brittle Reinforcement Structure Design: Reinforcement layers are engineered to resist brittleness under thermal stress conditions, maintaining structural integrity without fiber breakage or layer separation.
• Lightweight Offshore Handling Optimization: Optimized structure reduces overall weight while maintaining mechanical strength, improving manual handling efficiency on deck in harsh environments.
• Thermal Cycling and Weather Resistance System: Outer cover withstands repeated temperature changes, ice formation, seawater exposure, and UV radiation, ensuring long-term durability under Arctic conditions.

• Arctic Offshore Oil and Gas Transfer Operations: Widely used in Arctic and sub-Arctic offshore fields where crude oil and fuel transfer must be performed under extreme cold conditions.
• Northern Port Bunkering and Marine Fuel Supply: Applied in northern ports and high-latitude shipping routes where vessels require reliable fuel transfer systems during winter seasons.
• Cold-Region Offshore Support Vessel Operations: Used between supply vessels and offshore platforms operating in cold seas such as the North Sea and Norwegian Sea.
• Seasonal Offshore Exploration and Emergency Operations: Supports seasonal drilling campaigns and emergency offshore fuel supply missions where rapid deployment and low-temperature reliability are critical.

• Extreme Climate Material Engineering Capability: Specializes in developing elastomer systems designed for extreme temperature environments, ensuring flexibility and mechanical strength under severe Arctic conditions.
• Cold-Environment Performance Validation Testing: Each hose is tested under simulated low-temperature conditions to verify flexibility, impact resistance, and fatigue performance.
• Customized Design for Polar Operations: Provides engineering customization for cold-region applications, including enhanced flexibility ratings, insulation options, and coupling systems suitable for ice-prone offshore platforms.
• Reliable Global Supply for Remote Regions: Supports logistics delivery to remote northern offshore regions with stable supply chain management and technical support for installation in extreme environments.
