Designed without float collars, the submarine hose is suitable for use in connecting with subsea manifolds, and main submarine pipelines fitted in the hose strings on the single buoy mooring system. Single carcass hose and double carcass hose can be designed and manufactured according to the actual offshore application.

• Primary carcass inner lining:smooth, oil- and fuel-resistant seamless extruded NBR.
• Secondary carcass: specially designed to prevent defects or damage caused by accidental tearing or surface damage to the primary liner
• Reinforcement: multiple layers of high tensile textile cord, with one embedded steel wire helix
• Inner tube cover: smooth black oil-resistant synthetic rubber.
• Outer cover: smooth black synthetic rubber, resistant to abrasion, oil, seawater and sunlight, with a spiral orange stripe
• Floating medium (single/double carcass): closed cell foam
• Flange: ASME B16.5 Class 150 or Class 300 weld neck flange, with flat face (FF) or raised face (RF), depending on the requirements

Features
1. The submarine hose can be connected to a FPSO unit.
2. Rated working pressure: 15, 19 or 21 bar
3. Safety factor: 5:1
4. Electrical continuity: continuous or as requested
5. Leak detection system: the detector responds in the event of primary carcass failure and alerts the operators to remove damaged hose, preventing further damage or pollution.

Standards (All tests are conducted according to GMPHOM 2009 and customer specifications.)
Our submarine hoses are designed and manufactured in accordance with OCIMF standard, and are subject to the manufacturing and testing requirements of ISO 9000:2001.

• Working pressure: the submarine hose is suitable for operation at an internal pressure from -0.85 bar up to the rated working pressure.
• Flow velocity: the submarine hose is suitable for continuous operation at a flow velocity of 21 m/s.
• Applications: transfer of crude oil and liquid petroleum products (working temperature: -20°C to 82°C; aromatic hydrocarbon content not exceeding 50%)
• Electrical continuity: low-resistance connection provided by the copper wire and helical steel wire
