More Capacity for Demanding AtoN Configurations

For larger navigation marks, the challenge is often not simply keeping the buoy afloat. The buoy must retain sufficient capacity after the upper structure, lantern, topmark and other project equipment are installed.

The DX-PE2400-PU is designed around this requirement. Its large flotation platform provides the buoyancy margin needed for equipment-intensive AtoN applications, giving project teams greater flexibility when determining the final onboard configuration.

Foam-Backed Flotation

Additional Buoyancy Support Inside the Float

The float section is internally filled with polyurethane foam, adding buoyancy support throughout the main flotation body.

For navigation marks intended to remain deployed for extended periods, this foam-filled construction provides an additional layer of flotation security within the buoy itself rather than relying solely on the external shell.

Structural Support for Long-Term Deployment

Galvanized Steel Keel for Load-Bearing Areas

The lower structural section uses a hot-dip galvanized Q235 carbon steel keel frame to support the buoy's main load-bearing and marine operating requirements.

This gives the flotation body a dedicated structural foundation for the forces generated during deployment, mooring and long-term operation.

Marine Exposure Protection

Protection Focused on Exposed Metal Components

Metal components operating around seawater require their own corrosion-management measures.

The DX-PE2400-PU combines a hot-dip galvanized keel frame with fitted sacrificial anodes, while the access ladder is manufactured from 316-grade stainless steel.

These material and protection choices are applied to specific exposed structural areas to support long-term marine service.

Practical Access for Inspection

Integrated Access Ladder

Large navigation buoys may require access to the upper tower, lantern or other installed equipment during inspection and maintenance.

The DX-PE2400-PU incorporates a 316 stainless steel access ladder along the buoy structure, providing a defined access route to the upper platform.

Project-Specific Configuration

Configured Around the Final Navigation Mark

The DX-PE2400-PU can be configured according to the actual navigation marking requirement rather than supplied as one fixed setup.

Project-specific items can include:

• Marine lantern
• IALA topmark
• Buoy colour
• Mooring fittings
• Ballast arrangement

This allows the final buoy configuration to match the required navigation mark, equipment arrangement and deployment condition.

Suitable Applications

The DX-PE2400-PU is suitable for navigation marking projects including:

• Major channel and waterway marks
• Port and harbour approach marks
• Coastal navigation marks
• Larger floating AtoN installations
• Navigation marks requiring tall focal-height configurations
• Projects requiring multiple onboard AtoN components

Project Selection Considerations

What Should Be Confirmed Before Configuration?

For a buoy of this size, the final setup should be based on the complete navigation requirement rather than diameter alone.

Before configuration, the project should confirm:

• Required navigation mark type
• Required focal height
• Upper equipment arrangement
• Installed equipment weight
• Mooring requirements
• Required ballast condition
• Deployment environment

These factors determine how the final buoy should be configured before delivery.

FAQ

Can the upper equipment configuration be changed for different projects?

Yes. The lantern, topmark and related navigation equipment can be configured according to the required mark and project arrangement.

Can the ballast configuration be adjusted?

Yes. The ballast arrangement can be determined according to the final equipment setup and required operating condition.

Is the buoy supplied with a mooring system?

Mooring requirements can be reviewed as part of the project configuration. The appropriate fittings and mooring arrangement depend on the deployment conditions.

Which IALA marks can the buoy be configured for?

The buoy colour, topmark and lantern arrangement can be selected according to the required IALA navigation mark and applicable project requirements.
