TLS news & blogs

In offshore energy, oil & gas, mining, and industrial field operations, containers are no longer simple transport units. They have evolved into critical engineered spaces that support personnel workstations, mission equipment, and operational safety systems.

Unlike standard containers, these units must perform reliably in harsh, dynamic, and often hazardous environments—where structural integrity, system stability, and regulatory compliance are all essential.

To meet these requirements, TLS Offshore Containers has developed a comprehensive engineering framework covering structural design, system integration, manufacturing control, and validation testing. This ensures each solution is suitable for long-term field deployment under real operational conditions.

1. Structural & Safety Design: Built for Long-Term Reliability
Structural design is the foundation of every TLS container solution. Instead of focusing only on static load capacity, TLS engineering prioritizes real-world structural behavior under dynamic conditions.
In offshore and industrial operations, containers are frequently exposed to multiple handling scenarios, including lifting, transport vibration, stacking, and repeated relocation. These conditions introduce complex dynamic stresses that cannot be fully represented by theoretical calculations alone.
TLS designs focus on:

• Load transfer efficiency across the main frame
• Stress distribution at critical structural nodes
• Reinforcement of lifting points and corner castings
• Long-term fatigue resistance under repeated use

The objective is not only to achieve compliance in testing, but to ensure consistent structural performance throughout the entire service life.

2. Functional System Engineering: Ensuring Stable On-Site Operation
Beyond structure, functional systems determine whether a container can operate effectively in the field.
TLS functional units often integrate ventilation systems, electrical distribution, control systems, and environmental regulation components within a single enclosure.
Key design principles include:

• Balanced electrical load distribution to prevent localized overload
• System-level coordination between ventilation and internal layout
• Stable power supply design for sensitive equipment
• Practical maintainability for field service conditions

Rather than operating as independent components, all systems are designed to function as an integrated operational environment.

3. Hazardous Area Safety Design: Meeting Industry Risk Requirements
In offshore oil & gas and chemical environments, containers may operate in areas where flammable gases or combustible dust may be present. Safety design therefore becomes a critical engineering requirement rather than an optional feature.
Depending on the application, systems may include:

• Pressurization or ventilation control strategies
• Explosion-protected electrical equipment
• Safety interlock and shutdown logic

These designs are implemented to reduce ignition risks and maintain controlled internal conditions under hazardous environments.
TLS solutions are designed in accordance with internationally recognized safety frameworks, including:

• ATEX
• IECEx

These standards ensure compatibility with global offshore and industrial safety requirements.

4. Certification & Testing System: A Controlled Validation Process
Engineering design alone is not sufficient for offshore applications. Every TLS unit undergoes structured verification before delivery to ensure performance under real-world conditions.
Typical validation processes include:

• Structural load testing
• Lifting simulation under multi-point and uneven load conditions
• Transport vibration and handling scenario simulation
• Integrated functional system testing

For offshore applications, containers are also designed and tested in accordance with standards such as: DNV 2.7-1
The purpose of testing is to validate design assumptions and reduce operational uncertainty before field deployment.

Conclusion

The TLS engineering system is built on an integrated approach combining structural engineering, system design, safety compliance, and validation testing.

Rather than optimizing a single performance metric, the focus is on ensuring consistent reliability across the full lifecycle of offshore and industrial use.
​
For demanding environments, this approach provides a predictable and controlled solution—supporting safer operations, stable performance, and long-term field efficiency.

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

​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?

​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.

In the energy, chemical, and industrial sectors, the stable operation of equipment depends not only on design and manufacturing quality but also on how easy it is to maintain. 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. By making wiring easier, servicing smoother, and upgrades more flexible, we help customers feel confident, comfortable, and in control throughout the entire life cycle of their equipment.

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.
