Direct Deck Skin & Pontoon Aluminum
Internal
Floating Roof Systems
Overview
The Direct Deck Skin & Pontoon Aluminum Internal Floating Roof is designed for use within fixed-roof aboveground storage tanks to reduce vapor space and minimize evaporative losses.
Constructed using lightweight aluminum panels supported by buoyant pontoon chambers, the Direct Deck system floats directly on the stored product surface, supporting effective emissions control while maintaining structural stability across varying operating conditions.
Direct Deck internal floating roof systems are suitable for a wide range of tank diameters, stored products, and service environments. Configurations are available to support new installations, retrofit applications, and project-specific operational requirements.
Designed in accordance with recognized industry standards, Direct Deck supports environmental compliance, operational efficiency, and long-term asset performance.
Design & Construction
The Direct Deck IFR is engineered for durability, flexibility, and compatibility with integrated rim sealing systems.
- Key design considerations include:
- Lightweight aluminum deck panels supported by buoyant pontoon chambers
- Available in 500 and 1000 models based on API 650 structural design requirements
- Options for leg-supported or cable-suspended configurations
- Aluminum, hybrid aluminum-stainless, and all-stainless steel material options
- Modular construction to facilitate efficient installation
- Compatibility with mechanical shoe or wiper primary seals
- Secondary seal and foam dam options available for complete system integration
- Designed to accommodate operational loads and dynamic tank conditions
Systems can be specified to meet project-specific structural and regulatory requirements.
Key Benefits
Reduced vapour emissions
Minimises vapour space within fixed-roof tanks, supporting environmental compliance and emissions control objectives.
Lightweight yet structurally robust
Aluminum construction reduces overall roof weight while maintaining strength and stability.
Installation flexibility
Available in leg-supported and cable-suspended configurations to suit tank geometry and operational requirements.
Compatible with rim seal systems
Designed to operate in conjunction with primary and secondary sealing systems for integrated performance.
Suitable for retrofit applications
Modular construction allows integration into existing fixed-roof tanks.
Durable, low-maintenance design
Corrosion-resistant materials and simplified construction support long service life with minimal intervention.
Applications and Sectors
Direct Deck Skin & Pontoon Aluminum Internal Floating Roof systems are used across:
Petrochemical storage terminals
Fuel and hydrocarbon tank farms
Industrial liquid storage facilities
Tanks requiring emissions reduction and product conservation
Compliance and Standards
Direct Deck internal floating roof systems are specified to align with recognized industry codes and structural design standards governing aboveground storage tanks.
Designed in accordance with API 650 structural requirements, Direct Deck supports regulatory compliance, safe operation, and long-term mechanical performance across diverse operating environments.
Where required, system configuration can support emissions control requirements associated with EPA 40 CFR 60 and relevant local air quality regulations.
