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:

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.

In the high-stakes world of offshore oil, gas, and renewable energy, the margin for error is zero. Harsh salt-spray environments, explosive gas risks, and extreme weather demand equipment that does more than just "survive"—it must protect.
Enter the TLS A60 Offshore Pressurized Container. As the industry standard for hazardous area operations, these units are revolutionizing how teams manage equipment housing and personnel safety in Zone 1 and Zone 2 environments.
What is an A60 Pressurized Container?
An A60 pressurized container is a specialized offshore module designed to provide a safe, breathable environment within hazardous areas. The "A60" rating signifies that the unit can withstand a standard fire for 60 minutes, preventing the internal temperature from rising beyond safety limits.
By maintaining positive internal pressure, these containers prevent the ingress of flammable gases, making them the gold standard for offshore laboratories, control rooms, and equipment housing.
5 Key Features of TLS A60 Offshore Modules
1. Superior Fire and Blast Resistance
Safety is the foundation of the TLS design. Each unit is built to meet DNV 2.7-1 and EN 12079 standards. The A60-rated insulation provides a critical one-hour window for emergency response, protecting both high-value assets and human life.
2. Advanced Pressurization & Gas Detection (CPFG)
TLS integrates state-of-the-art Combined Pressurization, Fire & Gas (CPFG) systems. If the system detects a loss in pressure or the presence of external toxic gases, it automatically triggers an emergency shutdown (ESD) of all internal non-certified electrical equipment.
3. Marine-Grade Corrosion Protection
4. Fully Customizable Internal Layouts
Every offshore project has a unique footprint. Whether you need an offshore laboratory, a Remote Operated Vehicle (ROV) control center, or a hazardous chemical storage vault, TLS offers modular configurations tailored to your specific spatial and technical needs.
5. Global Compliance and Certification
Navigating international regulations is complex. TLS A60 units are fully certified to meet ATEX, IECEx, and SOLAS requirements, ensuring your project remains compliant regardless of its global location.
Essential Applications in the Offshore Sector
The versatility of the TLS A60 container allows it to serve multiple roles on rigs, FPSOs, and offshore platforms:
The TLS Advantage: Reliability When It Matters Most
Choosing the right offshore container is a balance of engineering excellence and regulatory peace of mind. The TLS A60 Offshore Pressurized Container doesn't just meet industry benchmarks—it sets them. By combining robust construction with intelligent safety automation, TLS helps operators minimize downtime and maximize personnel safety.

In high-safety environments such as laboratories, chemical plants, and new energy facilities, positive and negative pressure test containers are widely used to achieve effective environmental isolation and risk control. Stable and controllable ventilation is the foundation of safe operation. As the core driving equipment of the pressure control system, centrifugal fans play a critical role in maintaining reliable pressure conditions.
At TLS, centrifugal fans are systematically integrated with control systems in both positive and negative pressure test containers, providing stable, efficient, and application-specific pressure management solutions.
Application in Positive Pressure Test Containers
In positive pressure test containers, centrifugal fans continuously supply fresh air into the enclosure, maintaining the internal pressure higher than the surrounding environment. This positive pressure barrier effectively prevents external dust, harmful gases, and contaminants from entering the container, ensuring a clean and safe internal environment.
TLS selects centrifugal fans based on required airflow, pressure levels, and operational modes for different applications. Combined with optimized airflow design and high-performance sealing structures, the system ensures a stable and controllable positive pressure state, supporting safe equipment operation and personnel activities inside the container.
Application in Negative Pressure Test Containers
In negative pressure test containers, centrifugal fans are primarily used for controlled exhaust. By continuously extracting air from the enclosure, the internal pressure is kept lower than the external environment. This design prevents hazardous gases, pollutants, or test media from leaking outside the container, significantly reducing safety risks to personnel and surrounding areas.
TLS negative pressure solutions focus on exhaust stability and pressure consistency. The centrifugal fans are carefully matched with exhaust ducting and flow paths, ensuring uniform and reliable negative pressure conditions for high-risk testing and experimental applications.
System Control and Integrated Safety Design
To maintain long-term pressure stability, TLS integrates centrifugal fans with pressure sensors, pressure controllers, and airflow regulation devices. The control system continuously monitors internal pressure and automatically adjusts fan speed and airflow to achieve precise pressure control.
In addition, the container structure is designed with high airtightness and can be configured with explosion-proof components, interlock systems, and safety alarms based on project requirements. This integrated approach enhances overall system reliability and safety performance.
Conclusion
Through proven system design and strong customization capabilities, TLS effectively combines centrifugal fans with positive and negative pressure control strategies. The result is a stable, safe, and adaptable solution for various test container applications, meeting the demanding requirements of high-risk industrial environments.
