Description
Mainline Floating Hoses are used in offshore mooring systems, particularly for transferring crude oil or refined petroleum products between tankers and offshore terminals. These hoses are crucial for ensuring the safe and efficient transfer of materials in marine environments. Below are the typical details of a Mainline Floating Hose for offshore moorings:
1. Construction
- Inner Liner: Synthetic rubber or composite materials resistant to oil and gas, ensuring leak-proof operation.
- Reinforcement: Several layers of high-tensile fabric, including synthetic fiber or steel wire, for durability and pressure resistance.
- Outer Cover: Abrasion-resistant synthetic rubber with added UV protection, ensuring long-term durability in harsh marine environments.
2. Floating Layer
- Made of closed-cell foam or other buoyant materials, providing flotation even in case of damage to the hose.
3. Standard Sizes
- Inner Diameter: Typically ranges from 6 inches (150mm) to 24 inches (600mm), though larger sizes may be available for custom orders.
- Length: Usually around 12 meters per segment, with variations depending on application and system design.
4. Working Pressure
- Varies from 10 to 20 bars (145 to 290 psi), depending on hose specifications and intended use.
- Higher-pressure versions are available for deep-sea and heavy-duty applications.
5. Temperature Range
- Designed to operate in temperatures ranging from -20°C to 80°C, accommodating both warm and cold marine climates.
6. End Fittings
- Equipped with flange-type or swivel-type fittings made from corrosion-resistant materials (e.g., stainless steel) for easy connection to tanker or terminal piping systems.
- Hoses are generally compatible with the OCIMF (Oil Companies International Marine Forum) standards for safe and reliable operation in the oil and gas industry.
7. Performance Characteristics
- Tensile Strength: Capable of handling significant tensile loads during operations, with reinforcement layers designed to prevent rupture or detachment.
- Buoyancy: Engineered to maintain positive buoyancy even in rough sea conditions.
- Abrasion Resistance: Outer cover protects against physical wear from marine environments, ensuring longevity.
- Flexibility: High flexibility allows the hose to withstand constant movement and wave action during offshore mooring.
8. Certifications
The manufacturer of the products supplied by Precision Hoses Pty Ltd is certified under the ISO 9001:2008 Quality Management System, ensuring a consistent commitment to quality. Additionally, the manufacturer’s products have achieved key industry certifications, including the BV Certificate, CE Certificate, ECM Certificate, and CCS Certificate, awarded in 2010. These certifications highlight the exceptional standards of the products we resell, providing our customers with confidence in their reliability and performance.
These hoses are essential for facilitating reliable offshore oil transfer operations, reducing the risk of spills and ensuring the durability needed for harsh offshore environments.
