DNV containers have become an integral component of offshore logistics, driven by strict safety demands, harsh operating environments, and increasing regulatory compliance across energy, oil, gas, and maritime sectors. As one of the most trusted global standards, DNV 2.7-1 certified containers guarantee superior structural integrity, lifting safety, and environmental durability compared to conventional transport containers.
We supply advanced solutions that meet the diverse requirements of offshore operations. Our focus is on delivering high-strength, high-safety DNV-certified containers, engineered for dependable performance in the most hostile environments.
Understanding DNV Certification for Offshore Containers
The DNV 2.7-1 standard defines strict technical and safety requirements for containers used in offshore environments, including:
- Structural strength and load-bearing capacity
- Lifting and handling performance
- Environmental resistance and material quality
- Documentation and traceability
- Rigorous testing and inspection procedures
Unlike standard ISO containers, DNV offshore containers are designed specifically to withstand dynamic lifting, rough handling, and severe weather conditions commonly found in offshore sites, oil rigs, FPSOs, and marine vessels.
Types of DNV Containers for Offshore Applications
A wide range of DNV container types is available to optimise offshore operations, logistics, and site productivity. Key categories include:
DNV Cargo Carrying Units
These are used for the safe transport of materials, tools, and consumables. Configurations include:
- DNV open-top containers
- DNV half-height containers
- DNV basket containers
- DNV dry cargo containers
They feature enhanced corrosion resistance, secure locking systems, and heavy-duty lifting points.
DNV Workshop Containers
Mobile workspaces designed for offshore maintenance teams, equipped with:
- Reinforced flooring
- Ventilation and insulation
- Tool storage systems
- Optional electrical fit-out
These units function as fully operational offshore workshops, enabling productivity anywhere.
DNV Tanks
Used for transporting hazardous liquids safely offshore. Options include:
- DNV chemical tanks
- DNV fuel tanks
- DNV acid tanks
All tank systems meet strict safety and spill-prevention standards.
DNV Refrigerated Containers (Reefers)
Designed for temperature-controlled storage of food, medical supplies, and sensitive materials. Features include:
- Insulated panels
- Temperature monitoring
- Shock-resistant frame
These units guarantee offshore cold chain continuity.
Structural Safety Features of DNV Containers
All DNV-certified containers incorporate advanced safety innovations that exceed ISO standards, including:
- Certified lifting shackles
- Forklift pockets and pad eyes
- Corner castings and reinforced frames
- Shock and corrosion-resistant steel
- Pressure relief systems for tanks
Their design supports multiple lifting configurations using cranes, slings, or spreaders, ensuring safe deployment from supply vessels to offshore platforms.
Materials and Engineering Specifications
To comply with DNV 2.7-1, containers must be manufactured from high-grade steel with proven resistance to:
- Saltwater corrosion
- Impact forces
- Structural deformation
- Hot and cold temperature variation
Key engineering specifications include:
- Energy-absorbing design
- Structural redundancy to prevent collapse
- Quality weld profiles
- Certified coating systems
This makes DNV containers ideal for long-term use in marine environments.
Inspection, Testing, and Certification
Routine inspections are mandatory to maintain certification. Processes include:
- Visual inspection of welds and structure
- Load testing of lifting components
- Nondestructive testing (NDT)
- Coating and corrosion evaluation
All units must carry:
- Unique identification numbers
- Material certificates
- Load test reports
- Inspection logs
Compliance ensures maximum operational safety and traceability.
Why Offshore Industries Need DNV Containers
Offshore sectors demand equipment that meets the highest levels of safety, performance, and durability. Key benefits include:
- Reduced operational risk
- Enhanced worker safety
- Compliance with international regulations
- Long-term cost efficiency
