Offshore Mooring Buoys

Product catalog summary

Introduction
Foam mooring buoys are increasingly used in inland waterways and offshore environments as an alternative to traditional steel buoys. These buoys are available in various configurations, including chain-through types and those equipped with pad-eye, crucifix, quick release hooks, and navigation equipment. They are designed to resist seawater corrosion with galvanized or painted steel fittings.

Key Features

Un-skinable closed cell rigid foam core
Polyurethane elastomer outer skin
Polyester reinforced skin
Self-fendering with high impact absorption
Various end fitting options
Robust construction with low collision risk
Customizable colors, sizes, and shapes

Applications

Offshore and remote mooring
Temporary mooring in ports, docks, or harbors
Additional mooring for large vessels
Long-term mooring for infrequently used vessels
Inland waterways and navigation channels

Specifications
The document provides a table of specifications for different buoy models, detailing dimensions, weight, and net buoyancy. For example, the CMB1 model has a diameter of 700 mm, a height of 1500 mm, and a net buoyancy of 1000 kg.

Materials

Foam Core: Made from cross-linked poly or polyethylene foam, these cores are flexible, resilient, and closed-cell to prevent water absorption.
Polyurethane Elastomer: Used as a coating material, providing high load-bearing capacity and resistance to fatigue, abrasion, hydrolysis, and UV.
Reinforcement Layer: Nylon reinforcement adds strength and extends lifespan in extreme conditions.
Steel Frame: High-quality steel treated with painting or galvanization for durability.

Production Process
The production process involves creating a steel frame, forming the foam core, applying the coating, and attaching end fittings.

Mooring Buoys Specification The large mooring tube with 82.5mm ID will accept mooring chain of up to 20mm in diameter. The mooring tube is not moulded into the buoy but slides into a tubular section that runs down the center of the buoy enabling the tube to be replaced at any stage during the product’s service life. The mooring buoys can be installed with various fittings on the top. And the mooring buoys can be designed to meet different request. It has same design with common mooring buoys. Customized size are available upon request. www.doowinmarine.com - [email protected]
