Integrated Rim-Mounted Foam Dams
For floating roof storage tanks
Engineered foam dam systems designed to support rim-space fire protection by helping contain and direct fire-fighting foam where it is needed most.
Overview
Integrated rim-mounted foam dams are used on floating roof storage tanks to support fire protection within the rim space, where ignition risks can occur around the perimeter of the floating roof.
Installed at the rim of the floating roof, the foam dam creates a defined containment area that helps channel fire-fighting foam towards the source of a rim-space fire. This supports more effective foam application while helping reduce foam loss and improve response efficiency during emergency conditions.
DirecTank integrated rim-mounted foam dams are designed to accommodate roof movement, tank geometry, and operational requirements while providing a durable, corrosion-resistant solution for demanding aboveground storage tank environments.
Design & Construction
DirecTank integrated rim-mounted foam dams are engineered for strength, durability, and practical installation on floating roof tanks.
Key design features include:
- Rim-mounted configuration designed for floating roof applications
- Stainless steel construction for corrosion resistance and long service life
- Designed to channel fire-fighting foam within the annular rim space
- Compatible with new or existing secondary seal arrangements
- All-bolted installation with no hot work required
- Bracing options available to minimise connections to the floating roof deck
- Suitable for retrofit or new-build tank applications
Key Benefits
Supports rim-space fire protection
Helps contain and direct fire-fighting foam within the rim space during emergency response.
Efficient foam containment
Creates a defined foam application area, helping reduce foam loss and improve fire-fighting effectiveness.
Durable stainless steel construction
Corrosion-resistant components support long-term performance in demanding tank environments.
Retrofit compatibility
Can be installed on existing floating roof tanks and adapted to suit previous foam dam configurations.
No hot work required
All-bolted construction supports safer, more efficient installation during planned maintenance or retrofit works.
Designed around seal systems
Can be configured to work with existing or new secondary seal arrangements.
Applications
Integrated rim-mounted foam dams are suitable for floating roof tank applications including:
- Petrochemical storage tanks
- Fuel and hydrocarbon storage tanks
- External floating roof tanks
- Tank farms and terminals
- Retrofit fire protection upgrades
- Applications requiring rim-space foam containment
