In offshore oil & gas, offshore wind, and other marine engineering projects, containers are not only transportation units but also critical equipment that must withstand lifting operations, deck handling, and long-term offshore service. Compared with standard ISO containers, offshore containers are subject to far more stringent structural, safety, and certification requirements.
Among these, DNV 2.7-1 and EN 12079 are the most widely recognized international and European standards for offshore containers.
As a professional manufacturer of offshore functional containers, TLS integrates these standards into the design, manufacturing, and testing stages to ensure safety, reliability, and full compliance in demanding offshore environments.
DNV 2.7-1 and EN 12079: Understanding the Relationship
DNV 2.7-1, issued by Det Norske Veritas (DNV), is a globally accepted certification standard for offshore containers. It defines requirements for structural strength, lifting safety, testing procedures, marking, and periodic inspection.
In practical offshore projects, containers certified to DNV 2.7-1 are generally recognized as meeting the core requirements of EN 12079, and are widely accepted by European owners, EPC contractors, and classification societies.
Designing for Compliance from the Start
TLS adopts DNV 2.7-1 design principles from the earliest project stage, rather than treating certification as a post-production step:
Design documentation prepared for review by classification societies or approved third-party inspectors
Testing and Verification
In accordance with DNV 2.7-1, TLS offshore containers undergo mandatory testing and inspection, including:
Upon successful completion, a DNV 2.7-1 certificate is issued by DNV or an approved inspection body, typically covering compliance with EN 12079-1 and EN 12079-2 as well.
Marking, Certification, and Traceability
Each TLS offshore container certified to DNV 2.7-1 is clearly marked with:
These markings ensure full traceability and regulatory compliance throughout global offshore operations.
A Compliance Advantage for Global and European Projects
With DNV 2.7-1 certification and EN 12079 compliance, TLS offshore containers:
Certification is not just a formality—it reflects TLS’s commitment to engineering safety, quality control, and long-term reliability in offshore environments.

DNV 2.7-1, issued by Det Norske Veritas (DNV), is a globally accepted certification standard for offshore containers. It defines requirements for structural strength, lifting safety, testing procedures, marking, and periodic inspection.
- EN 12079 is the European standard for offshore containers and lifting equipment, and its technical requirements are largely aligned with DNV 2.7-1:
- EN 12079-1: Design and manufacturing of offshore containers
- EN 12079-2: Lifting sets
In practical offshore projects, containers certified to DNV 2.7-1 are generally recognized as meeting the core requirements of EN 12079, and are widely accepted by European owners, EPC contractors, and classification societies.
Designing for Compliance from the Start
TLS adopts DNV 2.7-1 design principles from the earliest project stage, rather than treating certification as a post-production step:
- Structural design based on offshore lifting conditions, considering dynamic loads, eccentric loading, and impact forces
- Reinforced main load-bearing structures and optimized lifting point arrangements
- Use of compliant steel grades, qualified welding procedures, and offshore-grade corrosion protection systems
- Full structural verification for functional containers such as accommodation units, laboratories, and equipment modules, ensuring internal installations do not compromise structural integrity
Design documentation prepared for review by classification societies or approved third-party inspectors
Testing and Verification
In accordance with DNV 2.7-1, TLS offshore containers undergo mandatory testing and inspection, including:
- Lifting load tests to verify structural safety margins
- Detailed inspection of lifting points and critical structural areas
- Welding quality and manufacturing consistency checks
Upon successful completion, a DNV 2.7-1 certificate is issued by DNV or an approved inspection body, typically covering compliance with EN 12079-1 and EN 12079-2 as well.
Marking, Certification, and Traceability
Each TLS offshore container certified to DNV 2.7-1 is clearly marked with:
- Manufacturer details and a unique serial number
- Maximum Gross Weight (MGW) and tare weight
- Design temperature range
- Certificate number and applicable standards (DNV 2.7-1 / EN 12079)
These markings ensure full traceability and regulatory compliance throughout global offshore operations.
A Compliance Advantage for Global and European Projects
With DNV 2.7-1 certification and EN 12079 compliance, TLS offshore containers:
- Are widely accepted across global offshore projects
- Meet entry requirements for European offshore and energy markets
- Reduce compliance risks and accelerate project approval and delivery
Certification is not just a formality—it reflects TLS’s commitment to engineering safety, quality control, and long-term reliability in offshore environments.

In high-risk industries such as petrochemicals, energy storage, and hazardous operations, positive pressure containers play a critical role in protecting both personnel and equipment. Ensuring their structural reliability is essential. One of the most important validation steps is the lifting test, which verifies the strength and stability of the container under operational conditions. This test is also key for obtaining international certifications like DNV 2.7-1 and EN 12079.
Purpose of the Lifting Test
The lifting test serves several critical functions:
Testing Procedure
The lifting test typically follows these steps:
Results and Applications
After testing, a third-party inspection report documents:
Conclusion
Lifting tests are a critical step in validating the structural safety of positive pressure containers. At TLS, all lifting tests are performed according to international standards, guaranteeing that every container delivered meets stringent safety and reliability requirements for high-risk environments.

Purpose of the Lifting Test
The lifting test serves several critical functions:
- Verify load capacity: Ensures that lifting points, base frames, and the overall structure can safely handle both rated and overload conditions.
- Check structural stability: Confirms that the container maintains its shape during lifting and that welds and connections remain intact.
- Support certification: Provides third-party testing evidence required for international standard compliance and customer assurance.
Testing Procedure
The lifting test typically follows these steps:
- Applying load: The container is lifted using cranes at specified angles, often around 45°, to simulate real-world lifting scenarios.
- Load levels: The applied load ranges from 100% to 125% of the safe working load to evaluate performance under overload conditions.
- Test duration: The container is held in the lifted position for several minutes to observe any structural shifts.
- Inspection points: Lifting points, base frame, welds, and overall structure are carefully checked for permanent deformation or damage.
Results and Applications
After testing, a third-party inspection report documents:
- Applied loads, lifting angles, and duration
- Any observed structural deformation or damage
- Final pass/fail evaluation
Conclusion
Lifting tests are a critical step in validating the structural safety of positive pressure containers. At TLS, all lifting tests are performed according to international standards, guaranteeing that every container delivered meets stringent safety and reliability requirements for high-risk environments.
