Heavy Duty Pipeline Floats UV Resistant Long Service Life Weatherproof

Introduction

Hongruntong Marine Hose Floats are professional floatation devices developed for port operations, shipyard activities, and nearshore marine engineering where hoses and temporary pipelines require stable buoyancy, frequent repositioning, and high resistance to mechanical impact. Compared with offshore dredging environments, port and shipyard operations typically involve tighter spaces, higher traffic density, and repeated handling, placing greater emphasis on durability, operational flexibility, and safety.

The Hose Floats are manufactured using a robust HDPE outer shell combined with a closed-cell foam core, ensuring consistent buoyancy and excellent structural integrity. This construction allows the floats to withstand frequent contact with quay walls, vessels, and workboats while maintaining reliable floatation performance. The split-type modular design enables fast installation and removal, making the product particularly suitable for temporary or frequently adjusted hose layouts commonly used in ports and shipyards.

Functionally, Hose Floats keep hoses and pipelines afloat at a controlled elevation, preventing dragging, kinking, and excessive bending during operations such as ship repair, hull cleaning, ballast water transfer, fire-fighting system testing, and temporary fluid pumping. By stabilizing hoses on the water surface, the floats reduce wear, improve operational safety, and help port operators and shipyards maintain efficient workflows with minimal downtime.

Case Study

At a large commercial shipyard serving bulk carriers and container vessels up to 80,000 DWT, temporary floating hoses were routinely used for ballast water discharge, fire pipeline testing, and equipment flushing during vessel repair and maintenance. These hoses, typically ranging from 300 mm to 500 mm in diameter, were frequently repositioned along the quay and exposed to repeated contact with hull surfaces, tugboats, and port infrastructure. The shipyard previously relied on improvised floatation solutions that offered limited impact resistance and inconsistent buoyancy, resulting in hoses partially sinking, increased abrasion, and frequent replacement.

Hongruntong Marine supplied a series of heavy-duty Hose Floats designed specifically for port-side operations, with reinforced HDPE shells and optimized buoyancy to support water-filled hoses under static and dynamic conditions. The split-body floats were installed directly onto existing hoses, allowing the shipyard to rapidly upgrade its floatation system without interrupting ongoing maintenance schedules. Once deployed, the hoses remained consistently afloat and properly aligned alongside vessels, significantly reducing dragging and contact damage. Shipyard operators reported improved safety during operations, easier hose handling by work crews, and a noticeable reduction in hose wear and replacement frequency. The floats were subsequently reused across multiple vessels and maintenance cycles, demonstrating strong durability and cost efficiency, and the shipyard standardized this Hose Float configuration for routine port operations.

Key Features

Optimized Buoyancy for Water Filled and Media Filled Hoses

Port and shipyard hoses are often fully filled with water or other fluids, creating substantial static loads that require precise buoyancy control. Hongruntong Marine Hose Floats are engineered to provide sufficient lift to keep hoses afloat under full-load conditions while maintaining a stable freeboard. This optimized buoyancy prevents partial submersion, which can otherwise lead to increased drag, handling difficulty, and accelerated wear at contact points.

Impact Resistant Structure for High Traffic Areas

Unlike offshore pipelines that operate in relatively open waters, port and shipyard hoses are exposed to frequent mechanical impact from vessels, tugboats, and handling equipment. The thick-walled HDPE outer shell of the Hose Floats offers excellent impact resistance, protecting the internal foam core from damage and ensuring long-term structural stability. This feature is critical in busy port environments where accidental collisions are difficult to avoid.

Split Type Modular Design for Frequent Reconfiguration

Shipyard operations often require hoses to be installed, removed, and repositioned multiple times within short periods. The split-type design of Hongruntong Marine Hose Floats allows fast installation without disconnecting hoses, significantly reducing labor time and improving operational flexibility. Floats can be added, removed, or repositioned as operational requirements change, making them ideal for dynamic port-side workflows.

Corrosion Free and Low Maintenance Performance

All materials used in Hongruntong Marine Hose Floats are corrosion-resistant and suitable for long-term exposure to seawater, oils, and common port-side chemicals. The closed-cell foam core does not absorb water, ensuring stable buoyancy over time and eliminating the need for routine maintenance associated with inflatable or metal floatation devices. This low-maintenance performance is especially valuable for shipyards managing multiple vessels simultaneously.

Applications

Shipyard Repair and Maintenance Operations

Hose Floats are widely used in shipyards to support floating hoses during ballast water discharge, fire system testing, hull cleaning, and machinery flushing. They keep hoses accessible and properly aligned alongside vessels, improving safety and efficiency during maintenance activities.

Port Side Temporary Fluid Transfer

In ports, temporary hoses are often deployed for water transfer, dewatering, or emergency pumping. Hose Floats provide a stable and reusable floatation solution that prevents hoses from sinking or becoming entangled in port infrastructure.

Nearshore Marine Engineering Support

For nearshore construction and maintenance projects conducted within port areas, Hose Floats support temporary pipelines and hoses, ensuring reliable floatation in confined and high-traffic marine environments.
