TLS news & blogs

​In the high-stakes world of offshore research and chemical analysis, laboratory safety isn't just a protocol—it’s a lifeline. As industries move toward more complex experimentation in remote environments, the demand for controlled, secure, and mobile workspaces has never been higher.

TLS Offshore Containers is leading this shift with its advanced Negative Pressure Laboratory Containers. In this guide, we explore why negative pressure is the gold standard for containment and how TLS is setting new industry benchmarks.

What is a Negative Pressure Laboratory?
A negative-pressure environment is a containment strategy where the air pressure inside the container is lower than the pressure outside. This creates a "vacuum effect" ensuring that air flows into the lab but cannot escape unless it passes through a specialized filtration system.

For laboratories handling volatile chemicals, hazardous biological agents, or offshore mud logging, this is essential to prevent the accidental release of contaminants into the surrounding environment or living quarters.

Key Features of TLS Offshore Negative Pressure Solutions
1. Advanced HEPA and Carbon Filtration
Safety starts with what you can’t see. TLS containers integrate medical-grade HEPA (High-Efficiency Particulate Air) and activated carbon filters. These systems capture 99.97% of airborne particles and neutralize toxic vapors, ensuring that exhaust air is clean and compliant with environmental standards.

2. DNV 2.7-1 Certified Robust Construction
Offshore environments are unforgiving. TLS builds its labs to meet DNV 2.7-1 and EN 12079 standards for offshore lifting and transport. These containers are:

• Fire-Rated (A60): Protecting personnel from external fire hazards.
• Corrosion Resistant: Specialized coatings for high-salinity maritime air.
• Blast-Resistant: Options available for high-risk zones.

3. Precision Control & Monitoring Systems
Maintaining a precise pressure differential requires constant vigilance. TLS units feature Integrated PLC Control Panels that allow researchers to:

• Monitor real-time pressure levels (typically between -30 Pa and -50 Pa).
• Receive instant alerts if pressure integrity is compromised.
• Adjust airflow based on specific experiment requirements.

4. Bespoke Customization
No two labs are the same. Whether you require a BSL-2 biosafety setup, a petrochemical analysis lab, or a clean room environment, TLS offers modular configurations tailored to your equipment and workflow.

​In the high-stakes environments of oil and gas, chemical processing, and mining, safety isn't just a priority—it’s a regulatory mandate. When operating in areas where flammable gases or dust are present, the IEC 60079-13 certificate stands as a critical benchmark for safety and operational integrity.

But what exactly is IEC 60079-13, and why is it essential for your facility?

What is the IEC 60079-13 Standard?
The IEC 60079-13 is a specialized international standard within the IEC 60079 series. While other parts of the series focus on individual components (like sensors or motors), Part 13 specifically governs equipment protection by pressurized rooms ("p") and artificially ventilated rooms ("v").

Essentially, this standard provides the framework for creating a "safe zone" within a hazardous area by using overpressure or ventilation to prevent explosive atmospheres from reaching non-certified electrical equipment.

Why the IEC 60079-13 Certificate is Crucial for Your Business
1. Risk Mitigation and Personnel Safety
The primary objective of IEC 60079-13 is to prevent catastrophic ignitions. By maintaining a pressurized environment, you ensure that even if a gas leak occurs nearby, the flammable vapors cannot enter the control room or E-House, where electrical sparking might occur.

2. Legal and Regulatory Compliance
Adhering to IEC standards is often mandatory for global operations. Obtaining an IEC 60079-13 certificate ensures you meet:

• ATEX requirements (in Europe).
• IECEx international certification schemes.
• Local occupational health and safety (OSHA) standards.

3. Cost-Effective Protection for Large Equipment
Rather than purchasing expensive, individually explosion-proofed (Ex d or Ex e) components, IEC 60079-13 allows you to house standard industrial equipment inside a certified pressurized room. This significantly reduces capital expenditure (CAPEX) for large-scale installations.

4. Global Market Access
Because IEC standards are internationally recognized, a certificate in IEC 60079-13 acts as a "technical passport," allowing your equipment or modular buildings to be deployed across borders with minimal regulatory friction.

Key Requirements for IEC 60079-13 Compliance
To achieve and maintain certification, a facility must demonstrate rigorous control over its pressurized environments. Key technical factors include:

• Purge Cycles: The system must be able to flush out any potentially hazardous air before the equipment is energized.
• Pressure Monitoring: Maintaining a minimum overpressure (typically ≥50Pa) is mandatory.
• Safety Interlocks: If pressure is lost, the system must trigger an alarm or an automatic power-off sequence to prevent hazards.
• Air Source Integrity: The air used for pressurization must be drawn from a guaranteed non-hazardous location.

How to Obtain IEC 60079-13 Certification
The path to compliance involves four critical stages:

• Engineering & Design: Integrating pressure sensors, fire dampers, and airtight seals into the room’s design.
• Rigorous Testing: Performance testing to ensure the room can maintain pressure under operational stress.
• Third-Party Auditing: Verification by a notified body to confirm the installation meets all IEC 60079-13 criteria.
• Lifecycle Maintenance: Periodic inspections to ensure seals haven't degraded and safety systems remain functional.

Conclusion
The IEC 60079-13 certificate is more than just a piece of paper; it is a vital safeguard for modern industrial operations. Whether you are managing a remote offshore platform or a complex pharmaceutical plant, understanding and implementing this standard is key to protecting your assets, your people, and your reputation.

MCC (Motor Control Center) shelters are the heart of power distribution and equipment control in industrial facilities. They manage critical operations but also face high safety risks. Electrical faults, short circuits, overheating, or the intrusion of flammable gases can quickly escalate into fires or explosions. That’s why designing MCC shelters requires a complete safety approach, combining fire protection, explosion prevention, and intelligent monitoring.

1. Fire Safety: Reducing Risks at the Source

TLS MCC shelters are built to minimize fire hazards from the ground up:

• Fire-resistant materials and structure: Steel structures with clear fire ratings, optional fireproof coatings, and A60-rated fireproof insulation panels (resistant to moisture and corrosion) provide durable protection.
• Cable and wall protection: Specialized fire seals around cable entries prevent flames from spreading.
• Functional separation: MCC cabinets, cable areas, and control zones are clearly divided. Fire-resistant partitions or compartments can further isolate potential incidents, reducing the impact of a single fire.

Other precautions, like optimized cable layout, proper ventilation paths, grounding systems, and short-circuit protection per international standards, help control risks at the earliest stage and buy valuable time for personnel and equipment.

2. Explosion Safety: Protecting Hazardous Areas

For industrial zones with flammable gases (Zone 1/Zone 2), TLS MCC shelters take additional measures:

• Optional positive pressure systems: Clean air maintains internal positive pressure, keeping flammable gases out. Pressure, flow, and gas monitoring can automatically trigger interlocks if conditions change.
• Explosion-proof electrical components: Critical devices, lighting, outlets, and junction boxes are selected based on hazardous area requirements.
• Sealing and airtightness: Doors, windows, and cable penetrations use industrial-grade seals, verified with gas-tight and sometimes water-tight testing, ensuring reliable protection in harsh environments.

These measures ensure the MCC room remains secure even under extreme conditions, preventing accidents before they escalate.

3. Smart Monitoring and Automation

TLS MCC shelters combine passive safety with active monitoring:

• Temperature, smoke, and gas detection systems operate in real time.
• Automated linkage with ventilation, positive pressure, and explosion prevention systems triggers alarms when abnormalities are detected.
• Power can be cut or emergency modes activated automatically.
• Interfaces allow seamless integration with plant DCS/SCADA systems for centralized monitoring.

This system-level approach reduces reliance on human intervention, creating fast, visible, and automated protection.

4. Conclusion: Safety as a Complete System

Fire and explosion protection is never about a single device or standard—it’s a full-system approach. TLS MCC shelters integrate structural protection, electrical safety, explosion-proof design, and intelligent monitoring to provide a stable, reliable control hub for high-risk industrial sites.
In demanding environments, true safety comes from careful planning, attention to detail, and long-term validation—not luck.

In offshore oil & gas platforms, offshore wind farms, and remote engineering projects, accommodation facilities are often a critical constraint during project mobilization. Delays in personnel deployment, incomplete on-site infrastructure, or repeated adjustments to temporary housing can directly affect construction schedules, cost control, and workforce stability.

Compared with traditional camps or permanent buildings—which typically involve long construction periods and limited flexibility—offshore accommodation containers offer an engineered and standardized solution that addresses the key requirements of speed, safety, and cost control. As a result, they have become a proven accommodation option for remote and offshore operations.

1. Engineered Structural Design for High-Risk Environments
Offshore accommodation containers are commonly designed and manufactured in accordance with recognized offshore standards such as DNV 2.7-1 and EN 12079. These standards are intended to address several typical challenges in remote and offshore environments, including:

• Structural fatigue caused by frequent lifting and repeated transportation
• Long-term corrosion exposure in high-humidity and high-salinity conditions
• Reliability requirements in locations with limited maintenance resources

By using high-strength steel structures combined with proven corrosion protection systems and structural redundancy, these containers maintain predictable structural performance throughout transportation, installation, and long-term operation. This helps reduce unplanned downtime and safety risks, providing a stable foundation for continuous project execution.

2. Modular Configuration for Flexible Project Requirements
Once traditional camps are constructed, modifications or relocation often involve high costs and complex logistics. In contrast, remote projects frequently face uncertainties such as changes in workforce size, schedule adjustments, or site relocation.
Through modular design, accommodation containers allow:

• Flexible combinations of single or double cabins, sanitary units, and common areas
• Adjustment of accommodation capacity according to different project phases
• Relocation and reuse after project completion, reducing stranded assets

This scalable, movable, and reusable approach is well suited to multi-project and cross-regional operations where flexibility is essential.

3. Factory Prefabrication to Shorten Project Lead Time
In remote areas, on-site construction is often constrained by limited labor availability, material supply challenges, and unpredictable site conditions. Accommodation containers address these issues through factory-based prefabrication, including:

• Structural fabrication
• Interior outfitting
• Basic functional testing

Once delivered to site, the units can be installed through lifting and simple utility connections, allowing accommodation facilities to be operational within a very short timeframe. This significantly reduces the preparation period during early project stages.

4. Predictable Lifecycle Cost Control
Unlike on-site construction, where scope changes often lead to cost overruns, modular accommodation containers allow configurations, schedules, and budgets to be clearly defined at the design stage.
In addition, the ability to redeploy containers across multiple projects lowers the effective cost per project over time. This makes them particularly attractive for energy and engineering companies operating long-term, multi-site developments.

Conclusion
In remote and offshore projects, accommodation facilities are not merely supporting infrastructure—they directly influence personnel safety, construction efficiency, and overall project timelines.
Through engineered design, modular configuration, and compliance with established offshore standards, accommodation containers transform housing from a site constraint into a planned, controllable, and reusable technical solution. They have proven to be a reliable and practical choice for remote operations where speed, safety, and cost predictability are critical.

Watertight testing reflects the reliability of seals, doors, windows, interfaces, and overall welding workmanship. It serves as an essential checkpoint to confirm that design and construction meet expected standards.

2. Importance of Testing Timing
The timing of watertight tests directly affects the accuracy of results and overall container quality:

• Mid-Production Testing

Conducting a preliminary watertight check once the container structure is largely assembled allows early detection of welding, seal installation, or interface issues. Adjustments or repairs at this stage are more cost-effective and help ensure a higher final product pass rate.

• Final Pre-Delivery Testing

Performing the final watertight test after the container is fully completed, including installed internal equipment and pipelines, is crucial. This not only serves as a part of the quality assurance before shipment but also simulates real-world conditions the container may face in use.

3. Common Watertight Testing Methods

• Hydrostatic Pressure Testing

Applying a controlled water pressure to check for leaks is suitable for assessing the overall watertight performance of a container.

• Spray/Rain Simulation TestingSimulating natural rainfall or sea spray helps examine the sealing performance of doors, ventilation openings, and interfaces.
• Combination of Visual and Instrumental Inspection

Using visual observation alongside instruments such as humidity sensors or leak detection paper can identify even minor water ingress with higher accuracy.

4. Key Considerations

• Seal Material Inspection: Ensure that seals, flange connections, and welds are intact and undamaged.
• Pre-Test Cleaning: Keep the container interior and exterior clean to avoid false leak detection.
• Stage-by-Stage Documentation: Record each test result to track defect repairs and quality improvements.
• Environmental Control: Water temperature, pressure, and testing duration should comply with design specifications to ensure reliable results.

5. Conclusion
​Watertight testing is a critical part of container quality assurance and an essential measure to protect both equipment and personnel. Proper scheduling of test timing, selecting the right testing methods, and strict adherence to standards can minimize leakage risks and enhance container reliability.

Through staged testing and final verification, manufacturers can ensure that every container delivered maintains reliable watertight performance in real-world conditions.
