​Overview
TLS Offshore Containers manufactures A60 DNV 2.7-1 certified pressurized cabins designed for hazardous offshore environments (Zone 1/Zone 2). Since 1998, the company has delivered flexible, high-spec modular solutions globally, featuring passive fire protection, integrated gas detection, and customizable layouts like laboratories and ROV cabins.

Key Offshore Safety Questions Answered in This Guide

1. What certification standards must offshore pressurized containers meet?
2. How do hazardous area ratings (Zone 1 vs. Zone 2) affect cabin specifications?
3. What are the standard and custom sizing options available for offshore modules?
4. What critical safety and life-support systems are integrated into a certified technical cabin?

Navigating Offshore Hazard Controls: DNV 2.7-1 & A60 Technical Standards

The Benchmark for Harsh Environments
Operating in the global oil, gas, and renewable energy sectors demands engineering that resists both catastrophic fire events and structural fatigue. Industry performance metrics indicate that standardized certified modules dramatically mitigate risk compared to uncertified alternatives. TLS has engineered these solutions since 1998, ensuring compliance with rigid global baselines.

• Structural Integrity: Certified in accordance with DNV 2.7-1 and EN 12079 structural design codes to guarantee safe dynamic lifting and deployment on offshore platforms.
• Thermal Boundaries: Feature A60 Passive Fire Protection, maintaining legal thermal boundaries against hydrocarbon fires for a minimum of 60 minutes.
• Regulatory Compliance: Designed to align with IEC60079-13 and SOLAS 2009 standards, with third-party approvals from leading maritime authorities like Lloyd’s, DNV, and ABS.

Zone Ratings and Pressurization Economics
Deploying non-rated equipment into explosive atmospheres is one of the most common operational failures in offshore logistics. True structural safety relies on active pressurization to exclude flammable gases from entering the workspace.

• Hazardous Area Ratings: Modules are built explicitly for Zone 1, Zone 2, or Safe Area deployment.
• Integrated Control: A specialized Combined Pressurization Fire & Gas (CPFG) Panel actively manages internal pressure and safety isolation.
• Electrical Safety: All interior elements—including lights, switches, and emergency stops—carry explicit Ex approval (e.g., Zone 2, Ex eb, Gas Group IIC, Temperature Class T3) to neutralize ignition risks.

Operational Constraints: Dimensions and Applications
A frequent oversight in offshore procurement is failing to balance standard transport dimensions with customized internal weight distribution. Modules must be adaptable to space limitations on vessels while maintaining highly specific layouts.

• Flexible Footprints: Available in multiple standard lengths, including 10ft, 15ft, 20ft, 30ft, and 40ft, alongside tailored construction dimensions.
• Diverse Applications: Configurable for highly specialized technical roles, including ROV Cabins, Mud Logging, MWD/LWD, Laboratories, Control Rooms, and Accommodation modules.
• Advanced Lab Infrastructure: Fully customized units can integrate high-risk equipment such as Ex-proof fume hoods, flammable storage cabinets, emergency showers, eye washers, and dedicated extraction arms.

Conclusion

Core Certification Matrix

• Structural Codes: Fully compliant with DNV 2.7-1 and EN 12079.
• Fire Safety: Standardized A60 passive thermal barrier.
• Atmospheric Classification: Rated for Zone 1 and Zone 2 hazardous areas via CPFG pressurization.
• Quality Management: Manufactured under strict ISO 9001 regulations.

Essential Safety Components

• Environmental Control: Automated fail-safe fire dampers and split-system air conditioning.
• Life Safety Systems: Air-lock doors, integrated smoke and gas detectors, emergency lighting, and dedicated escape hatches.
• Infrastructure Protection: Multi-Cable Transit (MCT) frames to seal electrical entries without compromising pressure or fire integrity.
