DNV 2.7-1 and EN 12079: How TLS Containers Meet Offshore Engineering Standards

1/9/2026

 
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.
  • 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.

The Global Passport: Why Functional Containers Need Multi-Standard Compliance (DNV, ATEX, IECEx)

9/28/2025

 
​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.
  • What it is: The DNV 2.7-1 standard is the definitive rule for offshore containers.
  • What it covers: It rigorously ensures the container’s strength, lifting safety, stacking ability, and impact resistance.
  • Why it matters: Meeting DNV 2.7-1 guarantees the container will remain stable, safe, and secure under extreme transport scenarios and rough sea conditions.

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.
  • IECEx (International System): This is the global standard for explosion-proof electrical equipment, verifying safe use in Zone 1/Zone 2 environments worldwide. It allows for global trade and acceptance.
  • ATEX (EU Directive): This is the mandatory requirement for the European market, covering everything from the design and manufacturing to the installation of equipment used in potentially explosive atmospheres.

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.
  • CSC (International Convention for Safe Containers): This certification is essential for the safe handling and transport of containers, ensuring they pass critical port inspections and meet shipping requirements.
  • ISO Standards: These standards work alongside CSC to ensure the container is structurally sound, legally compliant, and can pass customs and shipping requirements without issues.

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:
  • Structure: Follows DNV 2.7-1 for ultimate offshore safety.
  • Electrical/Safety: Meets both IECEx/ATEX for global explosion protection.
  • Logistics: Complies with CSC/ISO for seamless global transport.
  • Quality: Manufacturing processes follow ISO 9001 quality management.

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?

ATEX, IECEx, and CNEx Demystified: Your Guide to Global and Regional Safety Certifications

9/12/2025

 
​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.
  • Applicable Region: Primarily EU member states.
  • Certification Features: The ATEX Directive categorizes equipment into two main groups:
  • Group I: For mining environments susceptible to firedamp and combustible dust.
  • Group II: For all other surface industries.
  • Marking: Products with ATEx certification bear the "Ex" marking, indicating their compliance with the ATEX Directive. If your equipment needs to be sold or used in the European market, ATEx certification is mandatory.

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).
  • Applicable Region: Over 30 member countries globally, including the US, Australia, Canada, Japan, and Singapore.
  • Certification Features: The IECEx certification process involves rigorous testing, examination, and assessment of equipment to verify its conformity with IEC standards.
  • Advantage: Due to its international mutual recognition, equipment with IECEx certification can easily enter global markets without undergoing repetitive testing in each country, greatly simplifying international trade and project implementation.

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.
  • Applicable Region: China.
  • Certification Features: The CNEx certification process requires products to undergo strict testing and evaluation to verify their compliance with Chinese explosion-proof standards (which often reference IEC standards but have their own specific differences).
  • Importance: For any electrical equipment intended for use in hazardous environments within China, obtaining CNEx certification is a must to comply with local regulations.

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:
  1. Enhanced Safety: The stringent testing in the certification process ensures equipment reliability in hazardous environments. This minimizes the risk of explosive accidents and protects both valuable lives and assets.
  2. Legal Compliance: Adhering to the regulations and directives of ATEx, IECEx, or CNEx is fundamental for legal operations. Non-compliance can lead to hefty fines, legal consequences, and damage to a company's reputation.
  3. Expanded Market Access: IECEx certification serves as a passport to the global market. ATEx and CNEx certifications, in turn, open doors to the European and Chinese markets, helping you expand your business in specific regions.
  4. Standardization and Quality Assurance: These certifications provide uniform standards for the design, manufacturing, and use of explosion-proof equipment. This not only improves equipment interoperability but also ensures consistent quality and reliability.

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.

Welding, Coating, and Corrosion Protection – Keeping Containers Strong for 20 Years in Salt Spray

8/15/2025

 
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.

​
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.

So, what goes into building a container that can withstand the harshest ocean conditions? It’s a meticulous process, guided by expertise and an unwavering focus on safety and longevity.

The Foundation of Strength: Expert Welding & Structural Integrity
Every TLS offshore container begins with its backbone: the frame. We understand that structural integrity is paramount. That's why every primary weld on our container frames is performed by a certified welder, utilizing full penetration welding techniques. This isn't just about joining metal; it's about creating an unbreakable bond. To further ensure this critical step, third-party inspections meticulously verify the quality of each weld. Only after rigorous approval is the container coated with specialized marine-grade coatings, providing an essential shield against the relentless corrosion of saltwater.

Stability from the Ground Up: Precision Floor Installation
The floor of an offshore container is more than just a surface; it's a vital component of its overall stability and durability. At TLS, we start by laying calcium silicate plates on the lower deck, followed by the integration of fixed steel mesh for superior reinforcement. Careful placement of upper deck and floor dressings ensures a perfectly smooth and even surface. Our quality inspectors then conduct thorough assessments to guarantee the floor meets strict flatness standards, crucial for both safety and optimal functionality.

Comfort & Safety: The Role of Advanced Insulation
Life and work offshore demand comfortable and, more importantly, safe environments. TLS prioritizes this with high-quality insulation materials like rock wool. This insulation isn't just applied; it's carefully layered with adequate overlap and secured using fireproof tape. This meticulous approach ensures optimal temperature control and provides critical protection against fire, a paramount concern in offshore operations.

Seamless Functionality: Integrated Pipe, Air, and Cable Systems
A truly effective offshore container needs to seamlessly support essential utilities. TLS pays extra attention to the installation of water pipes, air pipes, and electrical cables. Pre-laid insulation and precisely positioned supporting booms on the top plate secure and align these systems, ensuring proper connection and optimal functionality. This dedication to detail guarantees the container is not only safe but also fully efficient for its intended offshore use.

The Interior Experience: Aesthetic and Functional Paneling
Beyond the robust exterior, the interior paneling contributes significantly to both the aesthetics and practicality of the container. TLS ensures every trim wall panel is installed with precision, resulting in smooth, flat surfaces. The fixing slots are prepared with meticulous care, and panels are installed with neat, straight splicing gaps, creating a polished and professional internal space that enhances usability.

Ready for Occupancy: Furniture & Appliance Installation
Once the structural elements are complete, the container transforms into a functional living or working space with the installation of furniture and appliances. TLS strictly adheres to preliminary design drawings for accurate furniture placement. Qualified professionals handle all power connections, and every connection undergoes rigorous inspections to guarantee safety and reliability. This ensures that every piece of furniture and every appliance meets the highest standards of quality and function.

Offshore Pressurized Containers: Meeting the Rigorous DNV2.7-1 and IEC60079-13 Standards

9/13/2024

 
​Introduction
Offshore environments demand the highest levels of safety and reliability, especially when it comes to pressurized containers. TLS Offshore Containers ensures its products not only meet but exceed these expectations by complying with two critical standards: DNV2.7-1 and IEC60079-13. This blog post will delve into these standards and how TLS's commitment to them translates to superior offshore pressurized containers.
 
DNV2.7-1 Standard: The Cornerstone of Offshore Container Safety
DNV2.7-1, developed by Det Norske Veritas (DNV), is a globally recognized standard for offshore containers. It covers design, materials, fabrication, testing, and inspection, ensuring containers can withstand the harsh conditions of offshore environments. Some key aspects of the DNV2.7-1 standard include:
  • Structural Integrity: The standard sets strict requirements for the strength and durability of containers, considering factors like pressure, temperature, and external loads.
  • Material Selection: Only materials with proven resistance to corrosion, fatigue, and other forms of degradation are permitted.
  • Fabrication and Welding: The standard outlines stringent procedures for welding and fabrication to ensure the structural integrity of the container.
  • Testing and Inspection: Containers undergo rigorous testing, including pressure testing, leak testing, and non-destructive examination, to verify their compliance with the standard.
 
IEC60079-13 Standard: Ensuring Electrical Safety in Hazardous Areas
IEC60079-13 is an international standard that addresses the design, selection, and installation of electrical equipment in potentially explosive atmospheres, commonly found in offshore environments. Key aspects of the IEC60079-13 standard include:
  • Classification of Hazardous Areas: The standard defines different zones based on the likelihood and duration of the presence of explosive gases or dusts.
  • Equipment Selection: Electrical equipment must be selected and certified based on the specific hazardous area classification.
  • Installation and Maintenance: The standard provides guidelines for the safe installation and maintenance of electrical equipment in hazardous areas.
 
TLS Offshore Containers: Exceeding Expectations
TLS Offshore Containers is committed to manufacturing pressurized containers that not only comply with but exceed the DNV2.7-1 and IEC60079-13 standards. This commitment is evident in several ways:
  1. Rigorous Design and Engineering: TLS employs experienced engineers who meticulously design containers to meet or exceed the structural and safety requirements of the standards.
  2. High-Quality Materials: Only the finest materials with proven track records in offshore environments are used in the construction of TLS containers.
  3. State-of-the-Art Manufacturing: TLS utilizes advanced manufacturing techniques and stringent quality control procedures to ensure every container meets the highest standards.
  4. Comprehensive Testing: Each container undergoes a battery of tests, including pressure testing, leak testing, and non-destructive examination, to verify its compliance with the standards.
  5. Certification: TLS containers are certified by recognized third-party organizations to ensure they meet or exceed the requirements of the DNV2.7-1 and IEC60079-13 standards.
 
Conclusion
TLS Offshore Containers' commitment to complying with and exceeding the DNV2.7-1 and IEC60079-13 standards ensures its pressurized containers offer unparalleled safety and reliability in demanding offshore environments. When you choose TLS, you can be confident that your containers are built to the highest standards, providing peace of mind and ensuring the success of your offshore operations.
