Containers used in offshore oil and gas operations, as well as other extreme environments, must meet specific certifications and standards to ensure structural safety, electrical safety, and explosion-proof performance. These certifications vary depending on the region and project requirements. This article provides a brief overview of several common container certifications and their applicable standards.

1. Structural Certification

Structural certification ensures the strength and stability of containers in extreme environments. Common structural certification standards include:
  • DNV 2.7-1: Developed by the Norwegian classification society (DNV), this is the primary structural certification standard for offshore containers. It specifies the design, manufacturing, testing, and inspection requirements for containers, primarily used in offshore oil and gas platforms, FPSOs, etc.
  • EN 12079: A European standard widely applied in the European and international markets. Similar to DNV 2.7-1, it focuses on the strength, lifting capacity, and corrosion resistance of containers.
These structural certifications ensure the reliability of containers during lifting, transport, and operation in extreme environments.

2. Explosion-Proof Certification

Offshore environments are often hazardous due to the presence of flammable and explosive gases, so containers need to have explosion-proof capabilities. Explosion-proof certifications ensure that containers do not produce sparks or explosions when used in hazardous areas. Common explosion-proof certification standards include:
  • ATEX (Europe): Applicable to the European market, especially for environments with potential explosion risks. The ATEX certification ensures that equipment can operate safely in explosive gas or dust environments.
  • IECEx (International Certification): IECEx is a global certification system based on the International Electrotechnical Commission (IEC) standards, widely applied worldwide. IECEx certification ensures that containers meet electrical explosion-proof requirements and can be safely used in hazardous areas.
  • IEC 60079-13 is a related standard, specifically regulating equipment with positive pressure protection, such as positive pressure containers. This design keeps the internal air pressure of the container higher than the external environment, preventing combustible gases from entering and ensuring the safety of the equipment.

3. Regional Certifications

Different regions and countries have different certification requirements for containers:
  • China: For domestic use, containers may be certified according to CCS (China Classification Society). While similar to international standards, CCS certification is not as widely recognized globally as DNV or other international certifications.
  • Europe: The European market typically requires containers to comply with EN 12079 and ATEX certifications. ATEX specifies explosion-proof requirements, while EN 12079 focuses on structural design.
  • United States: The U.S. market often uses API (American Petroleum Institute) standards, especially for containers used in offshore oil and gas exploration.
While some regional standards overlap, there are differences in certification requirements. Customers should select the appropriate certification based on the specific needs of the project and regional regulations.

4. Other Common Standards
  • ISO 9001: This is a quality management system standard. While not directly related to structural or explosion-proof requirements, it ensures quality control during the manufacturing process.
  • A60 Fire Rating: The A60 fire rating standard applies to containers designed to protect personnel and equipment in high-temperature environments. Such containers are typically used in high-risk areas like oil platforms and FPSOs.

Conclusion

Container certification standards include structural, explosion-proof, and regional certifications. The specific choice should be based on project requirements, local regulations, and environmental conditions. Common certification standards include DNV 2.7-1 (structural), ATEX and IECEx (explosion-proof), and regional certifications like CCS (China) and EN 12079 (Europe).

​In industries such as oil and gas, chemical processing, and renewable energy, the working environment is often fraught with extreme threats such as high pressure and explosive or flammable gases. TLS's Positive Pressure Explosion-Proof Container is a comprehensive safety solution that integrates physical isolation with intelligent monitoring. The core of the system lies in advanced positive pressure protection technology, which creates a safe "isolated zone" for critical equipment and personnel.

1. Core Defense Mechanism: Positive Pressure Protection Technology

The safety logic of the TLS system is based on the principle of pressure differential. The system continuously injects clean air through explosion-proof fans, maintaining an internal air pressure higher than the external atmospheric pressure.
  • Physical Barrier: The positive pressure environment forms an invisible air wall, effectively preventing the infiltration of flammable, explosive, or toxic gases.
  • Dilution Effect: Even in extreme conditions, any minor leaks are rapidly diluted by the continuous flow of clean air, completely eliminating the potential for combustion.

2. Intelligent Management: From Passive Defense to Active Monitoring

TLS’s system is not only a robust physical container but also an intelligent terminal integrated with precise sensors.
  • Automatic Pressure Control: The system automatically adjusts internal pressure based on environmental changes, ensuring that the pressure differential remains within a safe range.
  • Real-time Warnings: The monitoring system responds to pressure drops and abnormal gas compositions, triggering linked alarms for immediate action.
  • Data Traceability: The system records operational parameters in real-time, providing a reliable digital foundation for safety management.

3. Global Certifications and Engineering Applicability

To meet the stringent requirements of offshore drilling platforms, chemical parks, and other demanding environments, TLS’s system adheres to top international standards in its design and manufacturing:
  • International Standards: Complies with IEC 60079-13 (standard for positive pressure protected buildings) and DNV 2.7-1 (offshore container certification), ensuring structural integrity even in highly corrosive and vibrating environments.
  • Modular Deployment: The modular design supports rapid configuration, transport, and assembly based on project scale, significantly reducing on-site commissioning time.

Conclusion

TLS Explosion-Proof Pressurization Container System balances operational efficiency with environmental risk through three key aspects: positive pressure protection, intelligent monitoring, and modular customization. It serves not only as a compliance tool for high-risk industries but also as a core infrastructure to safeguard lives and protect assets.
