In high-risk industries such as petrochemicals, energy storage, and hazardous operations, positive pressure containers play a critical role in protecting both personnel and equipment. Ensuring their structural reliability is essential. One of the most important validation steps is the lifting test, which verifies the strength and stability of the container under operational conditions. This test is also key for obtaining international certifications like DNV 2.7-1 and EN 12079.

Purpose of the Lifting Test

The lifting test serves several critical functions:

• Verify load capacity: Ensures that lifting points, base frames, and the overall structure can safely handle both rated and overload conditions.
• Check structural stability: Confirms that the container maintains its shape during lifting and that welds and connections remain intact.
• Support certification: Provides third-party testing evidence required for international standard compliance and customer assurance.

Testing Procedure

The lifting test typically follows these steps:

• Applying load: The container is lifted using cranes at specified angles, often around 45°, to simulate real-world lifting scenarios.
• Load levels: The applied load ranges from 100% to 125% of the safe working load to evaluate performance under overload conditions.
• Test duration: The container is held in the lifted position for several minutes to observe any structural shifts.
• Inspection points: Lifting points, base frame, welds, and overall structure are carefully checked for permanent deformation or damage.

Results and Applications

After testing, a third-party inspection report documents:

• Applied loads, lifting angles, and duration
• Any observed structural deformation or damage
• Final pass/fail evaluation

Successful lifting tests allow containers to proceed to type certification, factory acceptance tests (FAT), and customer delivery, ensuring compliance with international standards and customer requirements.

Conclusion

Lifting tests are a critical step in validating the structural safety of positive pressure containers. At TLS, all lifting tests are performed according to international standards, guaranteeing that every container delivered meets stringent safety and reliability requirements for high-risk environments.

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.

Before a TLS special container leaves the facility, it undergoes a meticulous gauntlet of inspections. This rigorous pre-delivery testing isn't just about compliance—it’s about guaranteeing structural integrity, safety, and longevity in the world’s most demanding environments.

Understanding these essential checks is key to knowing you're investing in reliable, high-performance equipment. Here is an in-depth look at the container pre-delivery tests that make TLS containers worthy of your trust.
 
1. The Welding Test: Guaranteeing Core Strength
The foundation of any container's reliability is its structure, and the strength of the welds is non-negotiable. The Welding Test is critical for ensuring the container’s structural stability. It verifies the quality and strength of every joint to prevent catastrophic failures.

Purpose and Method: This test aims to confirm the quality of all welded joints and detect internal defects like porosity or weak connections. We use Visual Inspection for surface flaws like cracks, and Non-Destructive Testing (NDT), which includes advanced techniques like ultrasonic, X-ray, or magnetic particle testing, to find hidden flaws.

When It Happens: Conducted immediately after the welding process is complete. Any defects must be addressed before assembly to save time and cost.
 
2. The Lifting Test: Assessing Load Resilience
A container must be able to handle the extreme forces applied during loading, unloading, and transit. The Lifting Test evaluates the container’s response to these stresses, ensuring its stability and the integrity of the critical lifting points.

Purpose and Method: The goal is to ensure the container can safely handle its designed load and unexpected stress during transportation. We perform a Load Test by applying forces that exceed the rated capacity to simulate worst-case scenarios. Crucially, a Lifting Point Check verifies the strength of the lifting ears against international safety standards.

When It Happens: This check is performed after structural welding and assembly but before applying any surface treatments, as the raw structure needs to prove its strength first.
 
3. The Watertightness Test: Protecting Your Investment
Cargo protection is paramount. The Watertightness Test is essential to confirm the container’s resilience against environmental factors—specifically water intrusion from rain, snow, or humidity.

Purpose and Method: This test checks the sealing capability against external moisture. We use a Rain Test, utilizing high-pressure water jets or simulated heavy rainfall to check for leaks. A focused Seal Check examines critical areas like door seals, welded seams, and joints to ensure they meet stringent water resistance standards.

When It Happens: The test is conducted after door seals are installed and welding is complete, but typically before final surface treatments, which allows easier identification and repair of any leakage points.
 
4. The Paint Test: Durability Meets Presentation
The external coating is more than just aesthetics; it's the container's first line of defense against corrosion and environmental damage. The Paint Test ensures the longevity and visual quality of the surface coating.

Purpose and Method: This test focuses on the coating's durability, adhesion, and appearance. We use an Adhesion Test (such as cross-cut or pull-off methods) to verify the paint’s bond to the container surface, ensuring it won't peel or flake. Film Thickness Measurement is taken with specialized gauges, as proper film thickness is essential for long-term protective quality. Finally, a thorough Visual Inspection checks for uniformity, bubbles, cracks, or peeling.

When It Happens: This test is performed after the painting process is complete to validate the container’s visual and protective qualities.
 
The Rigorous TLS Test Sequence: A Step-by-Step Guarantee
To maximize efficiency and quality assurance, TLS follows a precise, integrated inspection flow:
Welding Test→Watertightness Test (Preliminary)→Lifting Test→Surface Treatment & Painting→Watertightness Test (Final)

Only after successfully passing all these checks is the container accepted and prepared for delivery. This commitment to quality is what guarantees performance you can rely on for your most demanding applications.

In the application of functional containers, transportation is often the most overlooked yet most critical step. Whether it’s intercontinental sea voyages or rough overland journeys, containers are exposed to far more demanding conditions than in daily use. TLS understands that a container can only be considered truly reliable if it can withstand the challenges of transport.

1. Redundant Strength in Structural Design
From the very beginning of the design process, TLS follows international standards such as DNV 2.7-1 and CSC certification for structural modeling and strength calculation. Beyond meeting basic load requirements, we add strength redundancy to critical points such as corner castings, bottom beams, and top beams. This ensures that even under extreme loads, impacts, or stacking pressure, the container structure will remain stable without deformation.

2. Finite Element Analysis (FEA) Verification
Before production, TLS applies finite element analysis (FEA) to simulate stress concentrations, twisting, and vibrations that may occur during transport. This digital approach helps identify weak points that might not be visible through traditional engineering experience, allowing us to optimize the design at the drawing stage.

3. High-Strength Materials and Welding Techniques
Material selection plays a decisive role in load-bearing performance. TLS uses high-strength marine-grade steel in line with international standards, combined with full-penetration welding and multi-layer weld seams. This creates a rigid frame structure that maintains integrity even under sudden impact loads, such as those caused by heavy waves or container lifting.

4. Dynamic Transport Testing and Validation
In addition to theoretical design and digital simulations, TLS conducts dynamic transport testing on finished products. These include lifting, drop, and long-distance vibration simulations, ensuring that containers can endure extreme transport conditions. Only products that pass these tests are delivered to customers.

5. Practical Experience in Real Projects
TLS containers have successfully passed the test of complex real-world transport conditions:

• Offshore projects: Equipment modules shipped with floating platforms across oceans, facing both waves and humid marine climates.
• Onshore projects: Energy storage containers transported over long distances through mountainous terrain, exposed to vibration and altitude differences.

Through these experiences, TLS containers have proven their ability to maintain structural stability during long journeys and provide effective protection for internal equipment, so that systems arrive on site in good working condition.

Conclusion
Transportation is not just a step in delivery—it is the final proof of product quality. With robust design, advanced analysis, strict testing, and proven field experience, TLS ensures that every container can withstand extreme conditions and provide reliable protection for its contents.

In offshore environments, where conditions are harsh and unrelenting, paint is far more than just an aesthetic finish—it is a critical component that ensures structural protection, long service life, and regulatory compliance. A high-performance coating system is essential to safeguard the safety, reliability, and certification standards of offshore containers.

1. Harsh Marine Environment: The Real ChallengeOffshore containers operate under extreme conditions that test the limits of any surface treatment:

• High salinity and humidity: Salt-laden air accelerates metal corrosion.
• Intense UV radiation: Leads to surface degradation and material aging.
• Drastic temperature changes and wave impact: May cause coating cracks or peeling.
• Continuous exposure to rain, oil, and contaminants: Challenges coating adhesion and chemical resistance.

Standard industrial coatings are insufficient—marine-grade protective systems are essential.

2. Key Functions of Offshore Paint Systems(1). Corrosion ProtectionA quality paint system is the first line of defense against steel corrosion. Common marine systems include zinc-rich epoxy primer, epoxy intermediate coat, and polyurethane or acrylic topcoat, meeting the requirements of ISO 12944 C5-M, the highest corrosion category. Such systems can offer protection for 15+ years.

(2). Fire ResistanceSpecialized offshore containers—such as accommodation units and control cabins—often require A60 fire protection. In these cases, fire-retardant coatings certified for high-temperature resistance are used to slow down fire spread, offering critical time for personnel evacuation.

(3). UV Resistance and Aging DurabilityTopcoats formulated with UV-resistant and anti-chalking properties help maintain surface integrity and visual appearance under constant sun exposure, especially on decks and external walls.

(4). Functional Identification and VisibilityColor-coded coatings help distinguish functional zones (e.g., living quarters, power rooms, labs). Reflective and safety markings further improve visibility, especially in low-light offshore environments.

3. Typical Paint System Configuration

• Primer: Zinc-rich epoxy – corrosion and rust prevention
• Intermediate Coat: Epoxy – enhanced adhesion and barrier properties
• Topcoat: Polyurethane or acrylic – weather resistance and aesthetics

These systems typically achieve a dry film thickness (DFT) of 220–300μm, suitable for long-term protection in aggressive marine conditions.

4. Key Certifications and StandardsTo ensure durability, safety, and compliance, offshore container coatings must meet several international standards:

• ISO 12944: Defines corrosion categories and service life expectations of protective systems.
• IMO MSC.215(82) / PSPC: Regulates performance of protective coatings for marine and offshore equipment.
• NORSOK M-501: Norwegian standard for surface preparation and coating in oil & gas sectors.
• Class Society Approvals (DNV, ABS, LR, etc.): Essential for most offshore modules; coatings are reviewed as part of structural integrity.
• IMO A754 (Fire Protection): Ensures fireproof coatings meet A60 insulation and integrity standards.
• Surface Preparation: Steel must be blasted to Sa2.5 to ensure proper coating adhesion and longevity.

5. Final Thoughts

In offshore functional containers, paint is not optional—it’s essential. A professionally designed and certified coating system not only protects against corrosion and fire but also extends the container's service life, reduces long-term maintenance costs, and elevates your brand’s reputation in the marine and offshore industry.

In extreme offshore environments such as oil drilling platforms, offshore wind farms, FPSOs, and floating work zones, functional containers—such as accommodation modules, laboratories, control rooms, and equipment enclosures—serve not only as essential units for work and living but also as dual safeguards for equipment safety and personnel protection. In these scenarios, safely lifting containers onto decks or vessels is a critical and often underestimated process.

To ensure lifting operations are stable, secure, and controllable, offshore containers must undergo rigorous lifting tests and obtain third-party certification. This process is not only a regulatory requirement, but more importantly, a vital safeguard for life and property.

1. What is a Lifting Test?

A lifting test simulates the real-world lifting conditions of a container before it leaves the factory. It thoroughly examines the structural strength, weld integrity, and the robustness of lifting points (pad eyes). The test is carried out according to classification society or industry standards and serves two main purposes:

• To verify that the lifting structure can support the design load.
• To ensure that the structure does not undergo permanent deformation or failure under extreme conditions.

2. Why is Lifting Test Mandatory for Offshore Containers?

(1) Mandatory Compliance with Standards
Offshore containers are governed by stringent industry standards such as:

• DNV 2.7-1: Design, manufacture, and certification of offshore containers
• ISO 10855: Offshore containers used in the oil and gas industry
• EN 12079: European standard covering lifting equipment and structural requirements

All of these standards mandate that containers must undergo lifting tests and obtain valid certification before delivery.

(2) High-Risk Marine Environments Demand Zero Compromise
Lifting operations at sea are exposed to confined spaces, vessel motion, and unpredictable weather. Any failure in the lifting structure or pad eyes can result in equipment damage, loss of life, or catastrophic accidents. A lifting test ensures structural integrity and reliability under such conditions.

(3) Essential for Project Approval and Global Market Access
Oil & gas operators, EPC contractors, and classification societies routinely inspect lifting design and certified test results. Containers without certified lifting tests will be rejected from offshore sites.

3. How is a Lifting Test Performed?

TLS follows a standard process to ensure safe and certified lifting capability:
(1) Pad Eye Inspection & Structural Review

• Pad eyes are manufactured using high-strength steel.
• Welds are subjected to non-destructive testing (NDT) such as UT or MT.
• The integration of lifting points with the frame is examined for structural integrity.

(2) Static Load Test

• Load applied at 2 times the rated lifting capacity, as per DNV 2.7-1.
• Container is suspended for at least 5 minutes.
• Checked for any signs of deformation, cracks, or structural failures.

(3) Dynamic Load Test (if required)

• Simulates lifting operations with movement and sway.
• Monitors structural fatigue and elastic recovery under repeated loading.

(4) Final Certification
Upon successful testing, a certificate is issued by an accredited classification society (e.g., DNV, BV, LR, CCS).
This certificate accompanies the container upon delivery and is recognized by global offshore project stakeholders.

4. TLS Practice in Lifting Test Assurance

As a specialized manufacturer of offshore functional containers, TLS conducts lifting tests on every unit destined for marine environments. Our process includes:

• Full compliance with DNV 2.7-1 or custom project specifications

​In the demanding world of offshore operations, where safety and reliability are non-negotiable, the integrity of every piece of equipment is paramount. This is especially true for offshore containers and their lifting equipment, which face extreme conditions daily. At TLS, we understand these challenges, which is why our containers are not just built to meet, but to exceed, the industry's most stringent standards, including DNV 2.7-1 and EN 12079.

These international standards aren't just guidelines; they're the bedrock of safety in offshore environments. They dictate everything from the design and manufacturing to the rigorous testing and certification processes that ensure an offshore container can withstand the immense stresses of its operational life. For TLS containers, this commitment to excellence is deeply embedded in our DNA.

The Gauntlet of Tests: What Makes TLS Containers Truly Robust
Before any TLS offshore container is deployed, it undergoes a series of intensive tests designed to simulate the harshest real-world conditions. These aren't just checks; they're comprehensive evaluations that prove the container's resilience and reliability.

1. All Point Lifting Test: Proving Structural Integrity Under Pressure
Imagine a container loaded with 2.5 times its rated payload (2.5R−T). During this test, the container is lifted simultaneously from all four corners and held for five minutes. This critical assessment allows us to precisely measure any deformation of the bottom frame, ensuring that the container's core structure can handle maximum loads without compromise.

2. Two-Point Lifting Test: Simulating Real-World Lifting Scenarios
Offshore operations aren't always perfectly balanced. The two-point lifting test simulates less-than-ideal lifting conditions. With the internal weight reduced to 1.5 times the rated payload (1.5R−T), we again meticulously measure the bottom frame deformation. This guarantees the container's stability and integrity even when lifted unevenly.

3. Fork Pocket Lifting Test (When Applicable): Strengthening Critical Interfaces
For containers equipped with fork pockets, this test is vital. With a weight of 1.6 times the rated payload (1.6R−T), the container is lifted via its fork pockets and held for five minutes. Whether by securing the fork arms or using a forklift directly for smaller containers, this test verifies the strength and durability of these crucial lifting points, preventing structural failure.

4. Vertical Impact Test: Designed for the Dynamic Offshore Environment
Perhaps the most telling test for offshore containers is the vertical impact test. This simulates the dynamic forces of being lifted and placed at sea, specifically designed to identify weaknesses from sudden impacts. With the container loaded to its rated payload (R−T), it's lifted with specially installed shackles and wire rope slings. The lift point is adjusted to create a 5-degree tilt in the bottom side beam, ensuring the highest point of the bottom frame is no more than 400mm above the lowest, and the lowest point is at least 5cm from the ground.

Then, the container is free-fallen by quickly releasing the shackle. After this controlled impact, every structural part of the container is thoroughly inspected for any cracks or damage. This stringent evaluation ensures that TLS containers can withstand the inevitable impacts of offshore operations, maintaining their structural integrity and protecting valuable cargo and personnel.

At TLS, our commitment to safety and reliability is unwavering. Through these rigorous testing protocols, we provide offshore containers that offer unmatched durability and peace of mind in the most challenging maritime environments.

5. Function Check: Testing System Operations Under Various Conditions
 
In this phase, the system is put through a series of operational checks under various conditions to ensure it reacts correctly to real-world scenarios:
 

• Normal and Bypass Operations: The system is tested in both normal and bypass modes to confirm that power and fan operations can be toggled appropriately.
• Alarm Tests: Various alarms are simulated, including combustible gas detection, low and high gas concentrations, fire alarms, and H2S gas detection. The system should automatically cut off power and sound alarms when necessary.
• Fan and Flow Rate Testing: The fan system and airflow are monitored, ensuring that the fan responds to changes in pressure or other alarm conditions, and that ventilation is maintained as per system requirements.
• Emergency Shutdown Test: The system’s emergency shutdown mechanism is triggered during simulated emergencies, ensuring that power is safely cut off in the event of a fault.
• Sensor Integrity Test: Sensor disconnections are simulated to ensure that the system responds promptly with alarms and performs an automatic shutdown if necessary.

 
Conclusion:
 
Once all the checks have been completed and all tests have been successfully passed, the equipment is deemed ready for deployment. The FAT report will detail each test's result, any issues encountered, and the corrective actions taken. The successful completion of the FAT ensures that the Pressurized Container will function safely and efficiently in real-world applications, meeting all required standards and regulations.

Welding is a crucial process in the construction and maintenance of offshore containers, ensuring the structural integrity and durability of these containers in harsh marine environments. To ensure the highest level of safety and reliability, welding inspection plays an essential role in identifying any potential flaws that could lead to structural failure. At TLS, we prioritize stringent welding inspection protocols in line with international standards, aiming to deliver top-quality, secure containers for offshore operations.
 
Why Welding Inspection is Critical for Offshore Containers 
Offshore containers endure extreme conditions, including exposure to saltwater, heavy loads, and severe weather, all of which put stress on welded joints. Even minor defects in welds can weaken the container’s structure, leading to potential safety risks. Welding inspection, as part of a comprehensive non-destructive testing (NDT) regimen, helps detect cracks, pores, and other imperfections that could compromise the container’s structural integrity.
 
Common Welding Inspection Methods
To maintain the quality and durability of TLS offshore containers, we employ a range of NDT methods to inspect welds. Here are some of the primary methods used in the industry:

1. Visual Inspection: The most straightforward approach, visual inspection involves examining the weld surface for visible defects such as cracks, undercuts, and improper welding techniques.
2. Ultrasonic Testing: This method utilizes sound waves to penetrate the weld and detect internal flaws that may not be visible on the surface, such as inclusions or porosity.
3. Magnetic Particle Testing: Widely used by TLS, this technique involves applying a magnetic field to the welded area and then coating it with magnetic powder. Any surface or near-surface defect disrupts the magnetic field, causing the powder to accumulate at the defect, making it easy to detect.
4. Radiographic Testing: By using X-rays or gamma rays, radiographic testing can capture images of the weld, revealing internal discontinuities and enabling detailed inspection of the weld’s structure.
5. Eddy Current Testing: This technique is effective for detecting surface cracks in conductive materials. It works by inducing currents that create a magnetic field, revealing flaws as changes in the electrical flow.

TLS's Approach to Welding Inspection
At TLS, we adhere to strict international standards for both production and inspection to ensure our offshore containers meet the highest quality requirements. Magnetic Particle Testing (MPT) is one of the preferred NDT methods we employ due to its reliability in detecting surface and near-surface flaws, crucial for offshore containers. Here’s an overview of our MPT process:

• Surface Preparation: We begin by cleaning the container surface, removing any grease, dirt, or impurities that might interfere with the inspection.
• Applying Magnetic Powder: A fine layer of magnetic powder is evenly applied to the surface, usually consisting of iron and magnetic particles.
• Magnetization: The container is placed in a magnetic field, which may be constant or alternating based on inspection requirements.
• Flaw Detection: A light source or magnetic probe helps visualize the magnetic powder distribution, revealing any cracks or imperfections on the surface.

The TLS Commitment to Quality
By incorporating advanced NDT techniques, TLS ensures that every offshore container meets strict quality control standards. Our dedication to robust welding inspection practices allows us to deliver containers that are both durable and dependable, ready for the toughest offshore conditions.
