A Robust Defense Against Offshore Corrosion: TLS Accommodation Modules Built for Harsh Marine Environments

In offshore platforms, marine wind farms, and nearshore engineering projects, accommodation modules are more than just living quarters—they are on the frontline of exposure to high salinity, humidity, and constant wind erosion. Choosing a truly durable and reliable accommodation container hinges on the professionalism behind its materials and anti-corrosion systems.

At TLS, we specialize in offshore functional modules. From material selection to surface treatment, we have developed a complete structural and protective solution specifically designed to withstand the rigors of marine environments—bringing our clients longer service life and lower maintenance costs.

Weathering Steel Structure: Built for Harsh Conditions

TLS offshore accommodation modules utilize high-strength weathering steel (such as Corten steel) for the main structure. Compared to conventional carbon steel, weathering steel forms a self-protective oxide layer when exposed to salt-laden air and moisture, significantly slowing corrosion and enhancing overall durability.

Key advantages include:

• Superior corrosion resistance, ideal for nearshore and high-salinity environments
• Reduced rust-related maintenance, lowering long-term O&M costs
• Rugged structure with excellent wind resistance and lifting performance
• We also reinforce key load-bearing components with:
• Enhanced bottom beams and corner post structures
• Multi-point welding to improve overall structural integrity
• Whether during frequent hoisting and transportation or in stacked deployments, TLS accommodation containers maintain outstanding load-bearing and anti-deformation performance.

Industrial-Grade Anti-Corrosion Coatings: The Key to Extended Service Life

To address the challenges of high salinity and humidity in offshore settings, TLS offers project-specific, industrial-grade anti-corrosion coating systems. Our coating solutions meet up to C5-M corrosion protection level—the highest classification for marine atmospheric environments.

Our standard three-layer coating system includes:

• Primer: Zinc-rich epoxy for superior adhesion and initial protection
• Intermediate coat: Epoxy thick film for forming a stable barrier layer
• Topcoat: Polyurethane finish for excellent UV resistance and long-term appearance retention

Custom configurations are also available—TLS supports specific thickness, color, or brand requirements to ensure compatibility with project conditions and service life expectations.

For optimal results, we can conduct Sa2.5-grade sandblasting before coating, and perform dry film thickness measurements, adhesion tests, and other quality control procedures throughout the process. Coating systems can be implemented in accordance with DNV and other international standards to meet the stringent requirements of offshore projects.

Proven Performance: Low Maintenance, Greater Peace of Mind

Numerous real-world offshore deployments have proven that TLS accommodation modules maintain structural stability and a clean exterior even after years of use. Clients consistently report “longer maintenance cycles and easier operation.” From wind farms and oil platforms to island camps, TLS containers deliver stable, long-term performance—creating greater value for our clients.
