1. Speed to Market: From Years to Weeks
In the digital race, time-to-market is everything. Constructing a traditional concrete data center involves lengthy zoning permissions, civil engineering, and complex onsite integration, often taking 12 to 24 months.
- The TLS Solution: Our Containerized Data Centers utilize a modular "plug-and-play" framework. Built and pre-commissioned in our advanced factory environment, these units compress deployment timelines from years into mere weeks. Once delivered to your site, they require minimal infrastructure setup, allowing you to go live and monetize your computing cluster almost instantly.
2. Built for AI High-Density Workloads & Advanced Cooling
Traditional data centers are built for standard CPU racks (typically 5kW to 10kW per rack). However, AI training and inference utilizing heavy GPU clusters demand upwards of 30kW to 100kW+ per rack, generating intense thermal loads that standard air conditioning cannot handle.
- The TLS Solution: TLS containerized environments are specifically engineered to support advanced liquid cooling and high-precision closed-loop ventilation systems. We design customized structural layouts that isolate hot/cold aisles efficiently, ensuring your high-performance AI hardware runs at optimal PUE (Power Usage Effectiveness) without risk of thermal throttling.
3. Flexible Engagement Models: Enclosure vs. Fully Integrated
At TLS, we understand that every engineering project has unique boundary conditions. To accommodate varying project scopes, we offer two flexible engagement models:
- High-Spec Enclosures: Durable, ISO-standard, or bespoke modular shells engineered for supreme structural integrity, ideal for clients who prefer to install their own internal server infrastructure.
- Fully Integrated Systems: Ready-to-deploy turnkey solutions. These feature factory-installed equipment—including IT racks, precision cooling units, fire suppression, security, and smart monitoring—complete with comprehensive onsite commissioning.
4. Supporting the Ancillary Ecosystem: E-Houses & Gensets
A data center is only as reliable as its power and backup infrastructure. True scalability requires the entire ecosystem to be modular.
Beyond the core IT container, TLS designs and manufactures specialized ancillary containerized units:
- Containerized Electrical Rooms (E-Houses): Factory-built, highly secure power distribution hubs featuring complete UPS backups, voltage adaptation, and smart grounding systems.
- Containerized Generator Sets (Gensets): Ruggedized, weather-proof, and sound-attenuated enclosures that provide rapid-response backup power for mission-critical applications.
5. Smart Safety & "Pay-As-You-Grow" CAPEX Efficiency
A modern container from TLS is not just a steel shell; it is a smart safety hub. Integrated with real-time monitoring sensors, our units constantly track temperature, humidity, smoke, and pressure variations, providing automated alerts to eliminate operational risks.
Furthermore, instead of risking massive upfront CAPEX on an oversized concrete facility, containerized solutions enable a "Pay-As-You-Grow" financial model. You expand your infrastructure linearly by adding more TLS modules only when your data or AI workloads demand it.

Summary
An offshore accommodation container is a functional module designed to provide temporary or long-term living space for offshore workers. It is widely used on oil and gas platforms, offshore wind installation vessels, pipe-laying ships, engineering support vessels, and onshore remote sites like mining areas, deserts, and polar regions. Compared to standard ISO containers, offshore living modules must withstand frequent lifting, marine corrosion, harsh weather, and continuous operation, requiring higher standards in structure, safety, and equipment.
Why Must Offshore Accommodation Containers Comply with International Standards?
Offshore living modules are not just living spaces; they are critical facilities to protect personnel safety. International projects usually require containers to meet DNV 2.7-1 and EN 12079 standards to ensure safe sea-land transport, offshore lifting, and long-term service. Meanwhile, CSC certification allows global shipping and multi-modal transport. For project owners, compliance with international standards means higher safety, smoother inspections, and easier project delivery.
What Key Configurations Should a High-Quality Offshore Living Container Have?
1. Extreme Weather Resistance
Offshore equipment is exposed to high salt spray, high humidity, and extreme climates. TLS Offshore Containers designs 20ft living modules to operate in environments from -30°C to 70°C. The exterior uses a C5-grade marine anti-corrosion coating to increase corrosion resistance and extend service life.
2. A60 Fireproof Standard
Offshore living areas require strict fire safety. TLS accommodation containers use an A60 fireproof insulation structure and self-closing A60 fire doors. The ventilation system features active fire dampers, and the bathroom has an independent mechanical exhaust to reduce fire and smoke risks.
3. Marine-Grade Electrical and HVAC Systems
To reduce on-site installation work, the electrical system is fully integrated before leaving the factory, using marine-grade flame-retardant cables. For hot climates, it features a split marine air conditioning system (4P) with two T3-class high-temperature indoor units, perfect for regions like the Middle East.
4. Plug-and-Play Quick Deployment
On-site construction time is highly limited. TLS containers feature a plug-and-play design with pre-installed freshwater inlets, greywater outlets, blackwater outlets, and standard power connections, allowing fast pipeline hookups on site.
5. Comfortable Long-Term Living Space
The standard two-bedroom, one-bathroom layout accommodates two workers. Each room includes a single bed, wardrobe, desk, and office chair, with pre-wired connections for TV, internet, and phone. The bathroom includes a 60L water heater (5000W-6000W) and heater fans for all-weather use.

What Is a CDU, and Why Should You Care?
Think of a CDU — short for Coolant Distribution Unit — as the hydronic control hub of a liquid-cooled server rack. Just as a home radiant heating system uses a manifold to distribute hot water from a boiler to individual room circuits and return it in a continuous loop, a CDU distributes chilled coolant from a facility's external cooling plant to every GPU cold plate inside a rack, then collects the heated fluid on the return path.
The elegance of the CDU lies in what it keeps separate. Inside every CDU is a plate heat exchanger — a compact device made of corrugated metal plates that allows thermal energy to transfer between two fluid streams without the fluids ever mixing. On one side flows the facility's primary coolant loop, circulating between the CDU and an outdoor dry cooler that rejects heat to the ambient air. On the other side flows the secondary loop, which travels directly through the cold plates pressed against the GPUs.
This two-loop architecture is more than an engineering preference. It's a containment strategy. Outdoor water circuits can harbor minerals, biological growth, and contaminants. Keeping that fluid entirely separate from the precision microchannel cold plates protecting million-dollar accelerators is not optional — it's essential.
Precision, Not Just Plumbing
What separates a CDU from a glorified water pump is its ability to manage three interdependent variables simultaneously: flow rate, pressure, and temperature.
Inside a single high-density AI rack, dozens of GPU cold plates may be operating in parallel. Each accelerator has a different thermal profile depending on its workload. The CDU must apportion coolant flow to each branch with enough precision that no chip starves for cooling — while simultaneously avoiding excess flow that wastes pump energy and stresses the plumbing. Hydraulic balancing across dozens of parallel circuits is a genuinely hard fluid dynamics problem, and it's one that cheap or poorly engineered CDUs fail at consistently.
Pressure management is even less forgiving. Modern GPU cold plates use microchannel flow paths just 100 microns wide — roughly the width of a human hair. These structures are extraordinarily efficient at pulling heat out of silicon, but they are also fragile. A pressure spike can crack a flow channel and flood a rack. A sustained pressure drop means insufficient coolant circulation and thermal runaway. The CDU must maintain stability within tolerances of ±0.05 bar across thousands of operating hours.
Temperature control closes the loop. For NVIDIA's Rubin-generation GPU clusters, the secondary side inlet temperature must hold steady at approximately 45°C. The CDU achieves this through a combination of variable-frequency pump control and modulation of the heat exchange rate on the primary side — governed by PID control algorithms that continuously read sensor data and adjust outputs in real time. This isn't thermostat logic. It's feedback-driven thermal management running at the systems level.
The Rubin Challenge: Twice the Power, the Same Space
The demands on CDU engineering have escalated sharply with each GPU generation, but the leap to Rubin-class infrastructure is particularly striking.
Where previous-generation GB-series racks required CDUs with roughly 1.3 MW of cooling capacity, Rubin racks demand 2.3 to 2.6 MW — approximately double — while the physical footprint of the CDU expands by only 200 millimeters in width. Engineers must fit twice the thermal throughput into roughly the same cabinet envelope. This requires fundamentally more efficient plate heat exchangers, higher-performance pump impellers engineered to minimize vibration and noise at elevated power levels, and a control architecture sophisticated enough to manage not just one rack but an entire coordinated tier of AI compute infrastructure.
There is also a reliability tension that the industry has not yet fully resolved. Traditional CDU design specifies redundant pumps so that a single hardware failure does not take down an entire rack. But the space constraints of Rubin-class CDUs have pushed some vendors to eliminate pump redundancy, trading a well-established safety margin for physical feasibility. The consequence — increased single-point-of-failure risk in racks worth tens of millions of dollars — is a trade-off the industry is still actively debating.
Why CDU Expertise Is a Genuine Moat
The precision engineering required to build a reliable CDU at Rubin-class specifications explains why capable suppliers remain scarce. Accurate multi-circuit flow balancing, sustained micron-level pressure stability, closed-loop temperature control, integrated leak detection, automatic fluid replenishment, and predictive fault logic — these are not features that can be bolted on after the fact. They reflect deep, accumulated expertise in fluid mechanics, materials science, embedded control systems, and large-scale thermal simulation.
As GPU power densities continue to climb and liquid cooling transitions from premium option to baseline requirement, the CDU will only grow in strategic importance. Understanding what a CDU actually does — and what distinguishes an exceptional one from an adequate one — is no longer optional knowledge for anyone involved in AI infrastructure planning, data center procurement, or cooling system design.
The GPU gets the headlines. The CDU keeps it alive.
