Mainline Submarine Hose without Collars

The Mainline Submarine Hose without Collars is designed for offshore oil transfer operations, connecting floating hose strings to subsea pipelines. Constructed with an oil-resistant inner liner and reinforced with high-tensile fibers, it withstands high pressures and harsh marine conditions. The hose features an abrasion-resistant outer cover for protection against environmental damage and flexible handling. With no collars, it offers greater adaptability in submerged environments, making it ideal for reliable transfer of crude oil and refined products in Single Point Mooring (SPM) and Conventional Buoy Mooring (CBM) applications.

Description

The Mainline Submarine Hose without Collars is a specialized hose used in offshore oil and gas transfer operations, designed for submerged applications. This hose connects floating hose strings to subsea pipelines, providing a flexible and durable solution for transporting crude oil, refined products, and other petrochemicals in deep-sea environments.

1. Construction

  • Inner Liner: Made from oil-resistant synthetic rubber or composite materials that ensure compatibility with crude oil and refined products, maintaining integrity under various conditions.
  • Reinforcement Layers: Constructed with multiple layers of high-tensile synthetic fibres or steel wire, providing the necessary strength and flexibility to handle high-pressure applications while resisting external forces.
  • Outer Cover: Features an abrasion-resistant outer layer made of synthetic rubber, offering protection against seawater, physical wear, and environmental factors commonly found in offshore settings.

2. Design Features

  • No Collars: Unlike collar-equipped hoses, this design allows for greater flexibility and ease of handling. The absence of collars reduces weight and potential stress points, making it suitable for certain applications where buoyancy control is less critical.
  • Buoyancy Control: Designed to achieve neutral buoyancy, the hose can float or remain submerged depending on operational requirements, allowing for adaptability in different offshore conditions.

3. Standard Sizes

  • Inner Diameter: Typically available in diameters ranging from 6 inches (150mm) to 24 inches (600mm), depending on the specific application and system requirements.
  • Length: Standard lengths are generally around 12 meters, with custom lengths available upon request.

4. Working Pressure

  • Rated to handle working pressures typically ranging from 10 to 20 bars (145 to 290 psi), ensuring reliability during oil transfer operations under pressure.

5. Temperature Range

  • Suitable for operation in temperature ranges from -20°C to 80°C, allowing for use in various offshore climates and conditions.

6. End Fittings

  • Equipped with flanged or swivel-type end fittings made from corrosion-resistant materials, such as stainless steel or galvanized metal. These fittings ensure secure connections between hoses and subsea pipelines or floating buoys.
  • Generally compliant with OCIMF (Oil Companies International Marine Forum) standards, ensuring safety and compatibility in marine oil transfer operations.

7. Performance Characteristics

  • Tensile Strength: Built to withstand significant tensile loads encountered during offshore oil transfer, particularly in dynamic underwater conditions.
  • Flexibility: Maintains excellent flexibility, allowing it to adapt to movement caused by waves, currents, and other marine factors.
  • Abrasion Resistance: The robust outer cover protects against damage from seabed contact and other environmental hazards, ensuring longevity in challenging conditions.

8. Applications

  • Primarily used in offshore oil transfer systems, especially in Single Point Mooring (SPM) or Conventional Buoy Mooring (CBM) operations.
  • Ideal for submerged hose strings that connect floating buoys to subsea pipelines for transferring crude oil or refined products.
