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:
  • 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
Successful lifting tests allow containers to proceed to type certification, factory acceptance tests (FAT), and customer delivery, ensuring compliance with international standards and customer requirements.

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.

Designed and manufactured to meet DNV 2.7-1 and EN 12079 offshore standards, and certified with CSC, this laboratory container ensures exceptional structural integrity during offshore transport, lifting, and long-term operation. It is built to withstand marine corrosion, extreme weather, and continuous vibration, offering reliable performance in harsh offshore conditions.

Multi-Layer Safety for Offshore Operations

Safety is a top priority for any offshore lab. The TLS 20ft lab container can achieve A60 fire protection rating, effectively reducing fire risks. It also integrates independent fire, gas, and smoke detection systems, providing immediate alerts to potential hazards and ensuring proactive safety for offshore operations.

The container can be equipped with independent ventilation or HVAC systems and features quick-plug power interfaces, allowing seamless connection to platform power and delivering a stable, controlled environment for laboratory work.

Comprehensive Laboratory Functionality

The container’s internal layout is optimized for practical offshore lab operations:
  • Laboratory benches and standing workstations
  • Stainless steel sink units with large washing areas and drainage
  • Workstations with telephone, computer, and LAN connectivity for data processing and communication
  • Ample storage cabinets above and below benches for consumables and tools
  • Fume hoods to ensure safe laboratory procedures
Additionally, the integrated water supply system can connect directly to the platform’s water source, ensuring continuous and efficient lab operations.

Professional Explosion-Proof Design for Hazardous Areas

For environments with flammable gas risks, the lab container can be designed for Zone 2 hazardous areas, with all electrical systems, lighting, switches, outlets, and cabling meeting explosion-proof requirements. Combined with anti-slip flooring, this ensures both personnel safety and reliable daily operation.

Rapid Deployment and Flexible Offshore Integration

TLS offshore lab containers support fast connection to various vessel or platform utilities, significantly reducing on-site installation and commissioning time. Their structural design also allows for stacking, optimizing limited deck space without compromising operational efficiency.

​In the high-stakes environments of oil and gas, chemical processing, and mining, safety isn't just a priority—it’s a regulatory mandate. When operating in areas where flammable gases or dust are present, the IEC 60079-13 certificate stands as a critical benchmark for safety and operational integrity.

But what exactly is IEC 60079-13, and why is it essential for your facility?

What is the IEC 60079-13 Standard?
The IEC 60079-13 is a specialized international standard within the IEC 60079 series. While other parts of the series focus on individual components (like sensors or motors), Part 13 specifically governs equipment protection by pressurized rooms ("p") and artificially ventilated rooms ("v").

Essentially, this standard provides the framework for creating a "safe zone" within a hazardous area by using overpressure or ventilation to prevent explosive atmospheres from reaching non-certified electrical equipment.

Why the IEC 60079-13 Certificate is Crucial for Your Business
1. Risk Mitigation and Personnel Safety
The primary objective of IEC 60079-13 is to prevent catastrophic ignitions. By maintaining a pressurized environment, you ensure that even if a gas leak occurs nearby, the flammable vapors cannot enter the control room or E-House, where electrical sparking might occur.

2. Legal and Regulatory Compliance
Adhering to IEC standards is often mandatory for global operations. Obtaining an IEC 60079-13 certificate ensures you meet:
  • ATEX requirements (in Europe).
  • IECEx international certification schemes.
  • Local occupational health and safety (OSHA) standards.

3. Cost-Effective Protection for Large Equipment
Rather than purchasing expensive, individually explosion-proofed (Ex d or Ex e) components, IEC 60079-13 allows you to house standard industrial equipment inside a certified pressurized room. This significantly reduces capital expenditure (CAPEX) for large-scale installations.

4. Global Market Access
Because IEC standards are internationally recognized, a certificate in IEC 60079-13 acts as a "technical passport," allowing your equipment or modular buildings to be deployed across borders with minimal regulatory friction.

Key Requirements for IEC 60079-13 Compliance
To achieve and maintain certification, a facility must demonstrate rigorous control over its pressurized environments. Key technical factors include:
  • Purge Cycles: The system must be able to flush out any potentially hazardous air before the equipment is energized.
  • Pressure Monitoring: Maintaining a minimum overpressure (typically ≥50Pa) is mandatory.
  • Safety Interlocks: If pressure is lost, the system must trigger an alarm or an automatic power-off sequence to prevent hazards.
  • Air Source Integrity: The air used for pressurization must be drawn from a guaranteed non-hazardous location.

How to Obtain IEC 60079-13 Certification
The path to compliance involves four critical stages:
  • Engineering & Design: Integrating pressure sensors, fire dampers, and airtight seals into the room’s design.
  • Rigorous Testing: Performance testing to ensure the room can maintain pressure under operational stress.
  • Third-Party Auditing: Verification by a notified body to confirm the installation meets all IEC 60079-13 criteria.
  • Lifecycle Maintenance: Periodic inspections to ensure seals haven't degraded and safety systems remain functional.

Conclusion
The IEC 60079-13 certificate is more than just a piece of paper; it is a vital safeguard for modern industrial operations. Whether you are managing a remote offshore platform or a complex pharmaceutical plant, understanding and implementing this standard is key to protecting your assets, your people, and your reputation.
