​In the demanding world of offshore operations, maintaining the integrity of temperature-sensitive cargo isn't just a requirement—it’s a mission-critical necessity. Whether you are transporting fresh produce, dairy, or essential meat supplies to a remote rig, the equipment you choose must withstand the harshest marine environments while keeping its contents in perfect condition.

TLS, a global leader in containerized solutions with over 30 years of experience, provides high-standard offshore refrigerated (reefer) containers designed specifically to meet these challenges.

Engineered for the Toughest Conditions
Offshore environments are unforgiving, but TLS reefers are built to endure. Every unit is manufactured according to strict DNV 2.7-1 and EN12079 standards, ensuring they are certified for safe lifting and transport in open seas.

To combat the corrosive nature of salt air and ensure a long service life, the outer panels are constructed from muffler-grade stainless steel. This choice of material offers high-grade protection, while the high insulation properties ensure that internal temperatures remain stable regardless of the external weather.

Precision Temperature Control
Precision is at the heart of the TLS refrigerated solution. Equipped with industry-leading refrigeration units from Daikin, Carrier, or Thermo King, these containers can maintain internal temperatures ranging from -20°C to +25°C.

The cooling process is powered by an advanced air duct system that circulates chilled or frozen air throughout the cargo before returning it to the refrigeration unit. To protect "living" products like fruits and vegetables, the units feature adjustable ventilation holes. This fresh air exchange (adjustable from 0-285m³/h) helps exclude warm, toxic air produced by the cargo, effectively preventing spoilage during long-distance transit.

Versatile and User-Friendly Design
TLS understands that deck space and operational efficiency are at a premium offshore. Our reefer containers are designed with several key features to streamline logistics:
  • Size Options: Units are available in 10ft, 20ft, and 40ft configurations, all of which comply with ISO sizes and CSC regulations for seamless intermodal transportation.
  • Ease of Handling: Each unit is fitted with integrated forklift pockets for easy loading and unloading, and all units are fully stackable to save valuable space on ships or in yards.
  • Hygienic and Safe: The interiors are designed to be easy to clean and hygienic. For added safety, customers can opt for specialized additions such as man-trap alarms, door curtains, shelving, and lashing rings.
  • Digital Monitoring: An integrated electronic control panel allows for easy monitoring and adjustment of the container's internal environment.

Global Reach, Local Support
With a head office in Singapore and major hubs in China and the UAE, TLS is positioned to help you wherever you are in the world. Our commitment is to provide the most cost-effective, highest-standard offshore container solutions to the global market.

​In the rapidly evolving sectors of offshore wind, oil and gas, and marine engineering, the "office" isn't just a workspace—it’s a lifeline. Operating in remote, high-sea environments requires infrastructure that goes beyond standard shipping containers.

At TLS, we provide DNV 2.7-1 certified offshore living and office modules engineered to withstand the planet’s most unforgiving conditions. Here is why choosing marine-grade certified modules is the smartest investment for your offshore project.

1. The Gold Standard: Understanding DNV 2.7-1 Certification
Safety is the primary directive in offshore operations. Our modules are built in strict accordance with the DNV 2.7-1 offshore container standard, which is globally recognized for ensuring structural integrity during high-risk maneuvers.
  • Dynamic Lifting Safety: Reinforced steel frames designed to handle the "snatch" loads of marine cranes in heavy swells.
  • Extreme Weather Resistance: Engineered to remain stable against high-velocity winds and aggressive wave impacts.
  • Sealing Integrity: Advanced gaskets and structural welds prevent seawater ingress and protect internal assets.

2. Fighting the Elements: C5-M Corrosion Protection
The salt-rich "C5-M" environment is the natural enemy of steel. Standard paint fails within months, leading to structural decay. TLS modules utilize a high-performance multi-layer coating system:
  • Epoxy Primers & Polyurethane Topcoats: Specifically formulated for long-term immersion in salt spray.
  • UV & Humidity Barriers: Prevents the "chalking" and cracking of paint caused by intense maritime sunlight.
  • Lower Maintenance Costs: Our coating system extends the asset's lifecycle, significantly reducing the frequency of costly on-site repainting.

3. Human-Centric Design: Productivity Through Comfort
Personnel morale is directly linked to operational efficiency. A TLS module is more than a steel box; it is a controlled, ergonomic environment.
  • Acoustic Insulation: Low-noise ventilation systems ensure a quiet space for rest and focus, even amidst the roar of offshore machinery.
  • Thermal Regulation: High-R-value insulation keeps interiors stable regardless of extreme external temperature fluctuations.
  • Smart Layouts: Fully customizable interiors including private sleeping quarters, washrooms, and high-tech office workstations with international-standard electrical fit-outs.

4. Seamless Logistics and Rapid Deployment
Time is money in marine engineering. Our modules are designed for "Plug & Play" deployment:
  • Standardized Footprints: Fully compatible with barges, container vessels, and flatbed trucks.
  • Integrated Lifting Lugs: Certified and tested for immediate use upon arrival at the dock.
  • Shock-Resistance: Internal components are secured to withstand the vibrations and shocks of transit.

In the manufacturing and application of modular containers, offshore containers, and various functional enclosures, watertightness is a critical factor for ensuring the safety of both equipment and personnel. Watertight testing not only verifies a container’s resistance to water but also directly impacts its service life, equipment protection, and operational safety.

1. Purpose of Watertight Testing​
  • Prevent Equipment Damage from Water
Storage containers, control rooms, or laboratory containers often house sensitive electronic devices and high-value equipment. Watertight testing ensures that containers remain protected against rain, seawater splashes, or accidental water ingress, preventing potential damage.
  • Ensure Personnel Safety
For accommodation or office containers, poor watertightness can lead to water leakage inside, increasing risks of slips, falls, or electrical hazards.
  • Verify Design and Construction Quality
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.
