Product Description
Marine Grade Floaters For Hoses
Strong Buoyancy Corrosion Resistant Saltwater Safe
Product Overview
Hongruntong Marine Hose Floats are advanced floatation devices designed for demanding offshore oil and gas operations, marine engineering projects, and long-distance floating pipeline systems. These floats are engineered to maintain consistent buoyancy and structural stability under harsh environmental conditions, including high waves, strong currents, and prolonged exposure to saltwater, UV radiation, and chemical contaminants commonly found in offshore applications.
Manufactured with a high-density polyethylene (HDPE) outer shell and reinforced closed-cell polyurethane foam core, Hose Floats provide exceptional load-bearing capacity while remaining corrosion-resistant and impact-tolerant. The modular split-body design enables installation on pipelines and hoses without disassembly, even in offshore locations where vessel access is limited.
Case Study: North Sea Offshore Oil Field
During an offshore oil field development project in the North Sea, an FPSO vessel required continuous transfer of crude oil using a 600 mm diameter flexible hose. Traditional buoyancy devices failed to provide uniform support, resulting in operational interruptions and accelerated hose replacement cycles.
Hongruntong Marine supplied heavy-duty Hose Floats specifically engineered for the offshore conditions. After deployment, the hose remained consistently afloat, aligned, and properly supported during continuous oil transfer operations. Mechanical stress on hose connectors and joints was reduced, significantly lowering the risk of leakage and unplanned downtime.

Key Features
Extreme Load-Bearing and Buoyancy Stability
Hose Floats are designed to support hoses carrying heavy oil, slurry, or chemicals over long distances. The closed-cell foam core provides uniform buoyancy and prevents sagging or partial submersion, ensuring operational stability even under dynamic offshore loads.
Chemical and UV Resistance for Offshore Conditions
The HDPE outer shell is resistant to saltwater corrosion, petroleum products, and UV degradation, ensuring long-term durability in offshore oil and gas environments. The combination of chemical resistance and mechanical toughness extends service life.
Split Body Modular Design for Offshore Installation
The modular split design enables rapid installation on hoses or pipelines without disconnecting the system, minimizing handling risks in offshore conditions. The floats can be easily removed or repositioned for maintenance or hose replacement.
Long Term Reliability and Low Maintenance
Unlike inflatable or metal floatation devices, these Hose Floats maintain consistent buoyancy over time without risk of air leakage or corrosion. Their durable construction ensures minimal maintenance, allowing operators to focus on mission-critical offshore activities.
Applications
- FPSO Crude Oil Transfer Lines: Used to support floating hoses during oil transfer from offshore platforms to shuttle tankers, ensuring hoses remain aligned and elevated while reducing bending stress and abrasion.
- Offshore Construction and Dredging Pipelines: Provides stable floatation for temporary or semi-permanent pipelines used in seabed construction, platform tie-ins, or dredging operations in offshore environments.
- Long Distance Marine Fluid Transfer: Ideal for long floating pipelines transporting water, chemicals, or hydrocarbons between offshore installations, keeping hoses buoyant, aligned, and protected from seabed contact and dynamic loads.

Frequently Asked Questions
Can Hose Floats withstand exposure to hydrocarbons and chemicals used offshore?
Yes. The HDPE shell and closed-cell foam core are resistant to petroleum products, oils, and common offshore chemicals.
Are these floats suitable for long-distance floating pipelines?
Absolutely. They are engineered for stable buoyancy and load distribution over long spans, maintaining hose alignment and reducing stress.
Can Hose Floats be installed in offshore conditions with waves and current?
Yes. The split-body design allows installation directly onto hoses offshore with minimal handling and maximum operational safety.
What hose diameters are typically supported for offshore oil and gas applications?
Hose Floats can be supplied for diameters from 300 mm up to 1,200 mm, with custom sizes available for specialized offshore pipelines.
How often do these floats require maintenance in offshore operations?
Maintenance is minimal. The durable HDPE shell and closed-cell foam maintain buoyancy and structural integrity over long operational periods without regular intervention.
