In demanding marine, dredging and oil-transfer operations, the right hose makes all the difference. The MONDEA brand offers two highly specialized hose lines: the Floating Dredger Hose and the Floating Oil Hose. These hoses are engineered to deliver outstanding performance in harsh environments—whether transferring abrasive sand and slurry, or safely handling oil and petroleum products on water.

What Are These Hoses?

Floating Dredger Hose

The MONDEA Floating Dredger Hose is built for marine dredging and reclamation operations. According to MONDEA’s distributor:

  • It “has been used on reclamation projects in different parts of Indonesia”.

  • It is “designed for abrasive material transfer applications and is equipped with extra abrasion resistant lining for longer lifetime use for dredging sand & slurry”.

  • Available up to diameter 40″ and standard length up to 11.8 m.

  • Suitable for suction & discharge services.

  • Incorporates a PE foam body to adjust to the specific gravity of pumped material so that the hose stays afloat.

Floating Oil Hose

The MONDEA Floating Oil Hose is designed for oil and petroleum product transfer in marine or offshore/near-shore installations. From the product description:

  • “Provides a means to safely transfer crude oil & liquid petroleum products from fixed offshore installations to shuttle tankers.”

  • The hose range includes submarine and floating type hoses configured for various loading facilities.

  • Built with high-performance oil & weather resistant materials to ensure long lifetime.

  • Up to diameter 34″, maximum length 11.8 m & various pressure ratings.

Key Features & Technical Highlights

Features of Floating Dredger Hose

  • Abrasion-Resistant Lining: Designed to handle abrasive media such as sand and slurry, long service life.

  • Buoyancy Design: The PE foam body ensures the hose floats or maintains buoyancy despite heavy pumped material.

  • Large Diameter Availability: Up to 40″ diameter gives high volume capability.

  • Marine/Harsh Environment Ready: Suitable for dredging applications in seawater, reclamation, etc.

Features of Floating Oil Hose

  • Oil-Resistant Materials: Tube made of black nitrile synthetic rubber, high oil resistance.

  • Reinforcement: High tensile nylon or synthetic textile cords, helix wire where applicable.

  • Weather & Abrasion Resistant Cover: The outer cover resists oil, abrasion, weathering, ozone.

  • Standard Industrial Applications: Tank trucks, in-plant oil transfer, offshore loading/unloading.

Typical Specifications (Indicative)

  • Floating Dredger Hose: diameter up to 40″, length up to 11.8 m.

  • Oil Suction/Discharge Hose: temperature range approx -30 °C to +80 °C; standard pressures ~150 psi for some models.

Applications & Use-Cases

Use-case for Floating Dredger Hose

  • Reclamation projects: transferring sand/slurry from dredging vessel to disposal site.

  • Offshore/near-shore dredging: floating hose ensures minimal seabed drag and simpler installation.

  • Suction & discharge for marine dredgers and barges needing abrasion resistant and buoyant hose.

Use-case for Floating Oil Hose

  • Oil transfer between offshore installations and shuttle tankers.

  • Dockside oil/fuel loading and unloading.

  • Refuelling vessels or barges where a floating hose helps avoid seabed drag and ensures safe transfer in marine environment.

How to Choose the Right MONDEA Hose

When selecting between the MONDEA Floating Dredger Hose and Floating Oil Hose, consider the following factors:

  • Media Type: Are you transferring abrasive slurry/sand or petroleum products? If abrasive media → dredger hose; if oil/petroleum → oil hose.

  • Operating Environment: Marine/sea condition, floating requirement, exposure to UV/salt water.

  • Diameter & Length: Based on volume and the logistics of your vessel or installation.

  • Pressure & Temperature Ratings: Ensure hose meets your system’s working pressure and temperature conditions.

  • Buoyancy & Specific Gravity: For dredger hose, the buoyancy design (PE foam body) matters if the pumped material is heavy.

  • Maintenance & Lifespan: Abrasion resistance and material quality will determine how long the hose lasts and how often downtime occurs.

  • Certifications & Compliance: Check for relevant certifications (e.g., TUV) and standards for your region or industry.

Installation & Maintenance Best Practices

  • Ensure the hose layout supports proper floating clearance—prevent dragging on seabed or entanglement.

  • Periodically inspect the hose outer cover for wear, abrasion, UV damage, or salt‐water degradation.

  • For dredger hoses, check buoyancy performance periodically—if damaged foam or cover, buoyancy may reduce.

  • For oil hoses, check for oil permeation, cover cracking, or abrasion from external equipment.

  • Store the hose properly when not in use: clean, drain, protect from UV and chemicals.

  • Use correct end fittings and ensure good alignment and anchoring on vessels, barges or marine installations.

Benefits & Value Proposition

Using MONDEA’s floating hose solutions delivers:

  • Reduced downtime thanks to abrasion-resistant or oil-resistant design.

  • Operational flexibility via floating design which simplifies marine/sea installation.

  • High throughput capability due to large diameters and lengths (especially dredger hose).

  • Cost savings over lifecycle through better durability and fewer replacements.

  • Enhanced safety and reliability in marine and oil‐transfer environments.

Frequently Asked Questions (FAQ)

Q: What is a floating hose and why is it important?
A: A floating hose includes a buoyancy design (such as a PE foam body) so it can float or maintain correct position on or near water surfaces. This is critical in marine dredging or oil transfer to avoid seabed drag, kinks or damage. For example, MONDEA’s dredger hose uses PE foam body.

Q: Can the MONDEA Floating Dredger Hose be used for heavy slurry and sand?
A: Yes — it is designed for abrasive material transfer applications (sand & slurry) and uses extra abrasion resistant lining.

Q: What kinds of oil products can the MONDEA Floating Oil Hose handle?
A: It is suitable for crude oil & liquid petroleum products from fixed offshore installations to shuttle tankers. Also for tank-truck suction/discharge of gasoline, oil and other petroleum base products up to ~50% aromatic content.

Q: Does MONDEA provide large diameter hoses for these floating applications?
A: For dredger hose the brand lists up to diameter 40″. For oil floating hose up to 34″ is mentioned in one spec sheet.

Conclusion

If you require high-performing floating hose systems for dredging or oil transfer in marine environments, MONDEA’s Floating Dredger Hose and Floating Oil Hose present compelling solutions. Their key strengths—buoyancy design, abrasion or oil resistance, large diameter availability—make them suitable for demanding operations. Assess your project’s media type, environmental conditions, size and pressure requirements, then select the correct MONDEA hose line for best results.
