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:

In the world of global energy, oil & gas, and chemical projects, a functional container is much more than a simple steel box. It's a critical, high-value platform housing sophisticated electrical, control, and safety systems. For any project, compliance is non-negotiable. It's the essential "entry ticket" that determines whether a platform can be delivered, installed, and smoothly put into operation. When you ship a unit across borders or install it in a hazardous environment, it must carry its "global passport" of certifications. At TLS, we understand that international compliance isn't a cost—it’s the foundation of trust and operational readiness. That's why multi-standard compliance is our first design principle. 1. DNV 2.7-1: The Offshore Safety Baseline For projects in the harsh, dynamic conditions of the sea—including offshore oil, gas, and wind—safety starts with the structure.
2. IECEx & ATEX: Dual Systems for Explosion-Proof Compliance When functional containers are deployed in petrochemical plants or other hazardous gas zones, explosion protection is paramount. You need proof that the systems inside will not become an ignition source.
The TLS Approach: We don't just use compliant components; we ensure the complete system is verified. From cable entries and junction boxes to lighting and fans, we use only certified explosion-proof components and verify their installation as a fully compliant, integrated unit. 3. CSC & ISO: The "Passport" for Global Transport Safety and explosion-proofing aside, your container needs to be shippable. Without the proper transport certifications, a project can be stalled indefinitely at a port.
These two certifications are the "passport" that allows your container to move legally and smoothly through global ports and shipping lanes. The Integrated Compliance Advantage Focusing on a single standard is a narrow approach that limits global deployment. Our integrated compliance strategy ensures the container is ready for any environment and any destination:
This multi-standard, full-process approach means that every functional container we deliver is not just shipped, but is fully validated and ready for safe, reliable operation anywhere in the world. Ready to ensure your next critical system is fully compliant, no matter the destination? TLS Offshore Containers / TLS Energy is a global supplier of standard and customised containerised solutions.

In industries like oil and gas, chemicals, and pharmaceuticals, potential explosive atmospheres from gases or dust are a constant risk. In these high-risk areas, a single spark could lead to catastrophic consequences. Therefore, ensuring the safety of both equipment and personnel is paramount. The key to achieving this lies in choosing the correct explosion-proof certification for your equipment. These certifications aren't just a sign of compliance; they are a guarantee of quality and safety. In this article, we'll dive deep into three major authority certification systems: ATEx, IECEx, and CNEx, helping you understand their differences, functions, and importance. ATEx Certification: The Passport to the European Market ATEx (Appareils destinés à être utilisés en ATmosphères Explosibles) is a certification system used primarily in Europe. It is based on the European Union's ATEX Directive, which defines strict safety requirements for equipment and protective systems intended for use in explosive atmospheres.
IECEx Certification: The Global "Passport" IECEx (International Electrotechnical Commission System for Certification to Standards Relating to Equipment for Use in Explosive Atmospheres) is an international certification system widely recognized by many countries worldwide. It is based on standards developed by the International Electrotechnical Commission (IEC).
CNEx Certification: The Mandatory Requirement for the Chinese Market CNEx (China National Explosion-proof Certification) is a certification system specific to China. It is regulated by the State Administration for Market Regulation (SAMR) and is a mandatory legal requirement in China.
Why These Certifications Matter Investing in equipment with authoritative explosion-proof certification brings long-term benefits to a company far beyond just a piece of paper:
Conclusion: In hazardous environments, safety is not an option—it's a necessity. Choosing equipment with authoritative certifications like ATEx, IECEx, or CNEx is a smart investment in safety, legal compliance, and market success. By understanding and correctly applying these certification systems, you build a solid foundation of safety for your operations.

When customers purchase functional containers, energy storage systems, or explosion-proof equipment, one question comes up again and again: “Will maintenance be difficult later on?” We understand that complicated wiring, cramped service space, and cumbersome upgrade processes can all increase maintenance costs and risks. That’s why we make “easy maintenance” one of our core design principles—right from the start—optimizing everything from structural layout to reserved interfaces. 1. Easier Wiring We use separated wiring zones inside and outside the container—high-voltage vs. low-voltage, power vs. communication—to reduce interference and misconnection risks. All cable interfaces are clearly labeled, and quick-release explosion-proof connectors make on-site wiring faster and less labor-intensive. 2. Smarter Access for Servicing Our internal layout follows an “easy to find, easy to reach” approach—service points are positioned for quick location and direct access. Wide aisles, service doors, and removable panels next to key components mean routine checks and replacements can be done without dismantling large sections, improving efficiency. 3. Flexible Upgrades We plan ahead for the future, reserving expansion interfaces and mounting points during the design stage. Whether adding fans, replacing controllers, or increasing voltage levels, upgrades can be carried out without large-scale modifications—extending the equipment’s service life. 4. Reducing Maintenance Costs from the Start These conveniences are not afterthoughts—they’re built into the design from day one. With modular structures, standardized parts, and clear documentation, we help customers keep maintenance effort low and reliability high. 5. Global Service Support For maintenance needs, we have service hubs in key regions worldwide, equipped with professional teams and spare parts. While coverage is still limited, we are committed to improving response speed to help customers solve problems quickly. Conclusion Maintenance should not be a burden—it should be simple and manageable.

For functional containers working offshore or in coastal environments, the daily challenge isn’t just waves and wind — it’s the constant presence of salt spray in the air. Chloride ions in salt spray can penetrate coatings and even reach the steel itself, causing corrosion that weakens structural strength and shortens service life. To combat this, TLS has optimized every stage of welding, coating, and corrosion protection so that containers can last longer in harsh marine conditions. 1. Welding – The First Barrier Against Corrosion Before leaving the factory, every weld is inspected to ensure there are no pores, slag inclusions, or other defects. During welding, TLS minimizes excess spatter and residue — not just for appearance, but to reduce tiny gaps where salt spray could start corrosion. For critical structural points, we use full welding rather than spot welding, which improves strength and reduces stress concentration points. 2. Coating – A Durable Protective Layer Steel left unprotected near the sea can start rusting within months. TLS uses a multi-stage coating process: first, surfaces are sandblasted to remove scale and oil while creating a rough texture for better adhesion. Next, we apply a zinc-rich primer for cathodic protection, followed by a highly weather-resistant polyurethane topcoat that maintains color and adhesion under UV light and salt spray. Every coating layer meets strict thickness standards so that protection is not compromised by application variations. 3. Corrosion Protection – From Design to Final Details Corrosion prevention starts at the design stage, not just during painting. TLS adds drainage slopes or holes in areas prone to water collection — such as the container base, door frames, and rainwater channels — to reduce moisture buildup. For bolts, locks, and other fittings, we use stainless steel or hot-dip galvanized materials, and then apply touch-up coatings after installation to avoid weak points. 4. Realistic Service Life Expectations Under normal use and maintenance, TLS containers can maintain their structure and corrosion protection for around 20 years in a C5-M (marine, very high corrosion) environment. This doesn’t mean the container becomes unusable after 20 years — it means corrosion risks remain controlled and the coating still performs during this period. With lower usage or regular maintenance, lifespan can be even longer. TLS Offshore Containers / TLS Special Containers is a global supplier of standard and customised containerised solutions. Wherever you are in the world TLS can help you, please contact us. Conclusion Salt spray corrosion is a fact of life in coastal and offshore environments, but it doesn’t have to shorten your equipment’s life. With precise welding, advanced coating systems, and thoughtful corrosion prevention in design, TLS ensures every container can perform reliably for years, even in the toughest marine conditions.
