The DX-ST2200A is designed for projects that require a strong steel buoy, a clear daymark and sufficient height for a marine lantern. Its four-chamber float body, protected steel structure and removable tail cone support reliable operation, maintenance and transport in demanding marine environments.

Reliable Navigation Marking for Coastal and Offshore Projects

For channel, coastal and offshore marking, the buoy must provide clear identification while supporting the required lantern and daymark configuration.

The DX-ST2200A combines a CCSB main body with a Q235B + CCSB framework, creating a dependable platform for marine navigation equipment. Its 2200 mm float and elevated lantern position support clear daytime and nighttime marking.

The welded float body is divided into four sealed chambers. The buoy is designed to remain afloat even if two chambers are flooded, providing additional flotation protection if part of the structure is damaged.

This internal arrangement is particularly important for projects where access for inspection or recovery may be limited.

Product Structure and Dimension Drawing

Sacrificial zinc anodes help protect the steel structure against corrosion during service. The buoy also uses an HT200 Cast Iron ballast and can be supplied with project-specific paint colours and coating thicknesses.

Lifting lugs are included to support lifting during production, transport and deployment.

The removable tail cone reduces the space required during transportation and allows the main buoy sections to be handled separately when required. This can be useful for international shipping and sites with limited handling space.

The topmark helps identify the buoy’s function during daylight.

Dexonmarine can configure the buoy with the appropriate IALA topmark, colour and light characteristic for lateral, cardinal, special, isolated danger, safe water or emergency wreck marking, according to Region A or Region B and local authority requirements.

Dexonmarine can supply and configure the buoy together with the main AtoN equipment required for the project, including:

• Marine lantern
• AIS AtoN
• RACON
• Solar power and battery system
• Remote monitoring equipment
• Mooring components
• IALA colour, topmark and light character

Before production, the buoy structure, equipment layout, power requirements, mounting interfaces and mooring arrangement can be checked together to ensure the main components are properly matched.

Dexonmarine combines steel buoy manufacturing with marine lantern, AIS AtoN, RACON and monitoring-system expertise.

• Project-specific marking: Colour, coating, topmark and light characteristics can be prepared according to the required navigation mark.
• Equipment matching: Dexonmarine matches the lantern, communication equipment, power system and mounting arrangement to the buoy and project requirements.
• Complete system supply: The buoy and selected AtoN equipment can be supplied as one coordinated system.
• Engineering review: Buoy structure, equipment load and mooring requirements can be checked before production.

It is intended for channel, coastal and offshore navigation marking projects that require a substantial steel buoy and an elevated lantern position.

The float body contains four sealed chambers and is designed to remain afloat even if two chambers are flooded.

Yes. Paint colour and coating thickness can be specified according to the required IALA mark, site conditions and customer requirements.

The steel structure is protected by a marine coating system and sacrificial zinc anodes. The final coating specification can be selected according to the installation environment and maintenance requirements.
