A marine hose is a heavy-duty flexible hose specifically designed for marine engineering, offshore projects, and port operations. It is used to safely transfer oil, water, slurry, or other fluids between ships, offshore facilities, and coastal infrastructure under harsh sea conditions.
Unlike standard industrial hoses, marine hoses are engineered to withstand seawater corrosion, wave-induced movement, UV exposure, and high mechanical stress, making them a critical component in offshore construction, dredging projects, and marine logistics systems.
Typical Marine Engineering Applications
Marine hoses are widely used in engineering-driven and procurement-led projects, including:
- Offshore and nearshore oil transfer systems
- Ship-to-ship and ship-to-shore fluid transfer
- Dredging and reclamation projects (sand, mud, slurry)
- Seawater intake and discharge for marine facilities
- Port, jetty, and terminal loading systems
These applications require hoses with stable performance, long service life, and compliance with project specifications.
Marine Hose Structure (Engineering Overview)
A standard marine hose is a multi-layer composite structure, optimized for strength, flexibility, and durability:
1) Inner Lining
-Directly contacts the conveyed medium
-Oil-resistant, abrasion-resistant, or chemical-resistant rubber
-Selected based on fluid type, temperature, and concentration
2) Reinforcement Layer
-High-strength textile cords or steel wire reinforcement
-Provides pressure resistance, tensile strength, and dimensional stability-
-Designed to meet the required working and burst pressures
3) Outer Cover
-Resistant to seawater, UV, abrasion, and weathering
-Protects the hose in harsh offshore and port environments
-Floating marine hoses may include buoyancy layers to maintain stability on the water surface.
Working Conditions in Marine Projects
Marine hoses are designed for continuous operation in demanding marine environments, including:
- Constant exposure to seawater and salt spray
- Dynamic bending caused by waves, tides, and vessel movement
- Axial loads and tension in floating hose strings
- Internal pressure fluctuation during pumping operations
For engineering projects, hoses are typically specified with high safety factors to ensure reliability and reduce operational risk.
Standards & Procurement Considerations
Marine hoses for offshore and port projects are commonly manufactured according to:
— OCIMF guidelines (for oil and offshore transfer)
— ISO / EN rubber hose standards
— Project-specific technical specifications
Key procurement parameters include:
- Hose diameter and length
- Working and burst pressure
- Bending radius and reinforcement type
- End fittings and connection standards
- Service life and maintenance requirements
