Independent buoyancy compartments, deep-draft stability and integrated mooring control

2600 mm Diameter | 4 Buoyancy Compartments | 4042 mm Draft | 3000 mm Ballast Tail Tube

Project Value at a Glance

Four-Compartment Buoyancy

Independent buoyancy sections provide additional flotation security if localized hull damage occurs.

Deep-Draft Stability

The long underwater structure places significant mass below the float body to support a stable upright operating condition.

Integrated Mooring Control

Ballast, mooring chain and sinker are considered together as part of the final deployment configuration.

Buoyancy Protection Beyond a Single Hull Space

For long-term navigation marks, localized hull damage should not immediately affect the entire flotation volume.

The DX-ST2600 divides the main hull into four independent buoyancy compartments, helping isolate individual sections and preserve reserve buoyancy across the remaining compartments.

Stability Built into the Underwater Structure

The DX-ST2600 uses a 3000 mm ballast tail tube, approximately 2000 kg cast-iron ballast and an integrated adjustable ballast arrangement.

Together with the 4042 mm draft, this creates a distinctly deep vertical mass distribution for projects where upright stability and controlled buoy behaviour are important.

Mooring and Ballast Planned as One System

Defined Construction for Long-Term Marine Deployment

The structural protection system includes:

• CCS Grade B marine steel main hull
• 8 mm main hull plate
• 10 mm ballast tail tube plate
• Q235 galvanized steel upper structure
• International Paint protective coating
• ≥360 μm total dry film thickness

Best Fit Projects

The DX-ST2600 is particularly relevant when the project requires:

• Independent buoyancy compartments for added flotation security
• A deep-draft navigation buoy configuration
• Ballast adjustment around site conditions
• Mooring chain and sinker integration
• A tall navigation mark with controlled vertical stability

When to Choose the DX-ST2600

Choose the DX-ST2600 when the project needs:

• Compartmentalized buoyancy rather than one single flotation space
• A deep underwater mass arrangement
• Site-adjustable ballast
• Mooring chain and sinker integration
• A tall steel navigation mark for long-term deployment

Frequently Asked Questions

Why use multiple independent buoyancy compartments?

Compartmentalization helps limit the effect of localized hull damage by separating the main flotation volume into independent sections.

How is the final ballast arrangement determined?

The final ballast should be reviewed together with buoy configuration, installed equipment, mooring arrangement and site conditions.

Is the mooring system considered separately from the buoy?

For this model, the ballast, mooring chain and sinker should be evaluated together with the buoy's operating condition to form the final deployment arrangement.

What project information should be confirmed before production?

Deployment water depth, required navigation function, installed equipment, mooring conditions and site-specific operating requirements should be confirmed before final configuration.
