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

​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.

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.

Container weld inspections are crucial to ensure structural integrity and safety. Among the non-destructive testing methods available, Magnetic Particle Inspection (MPI) stands out. This technique utilizes magnetic powders to reveal defects and discontinuities in ferromagnetic materials without causing any damage.
 
The process of MPI involves magnetizing the ferromagnetic workpiece, which leads to localized distortions in the magnetic field lines when discontinuities are present. This results in a leakage magnetic field that attracts magnetic powders applied to the surface. When appropriately illuminated, these powders form visible indications, allowing for the identification of location, size, shape, and severity of any defects.
 
For effective flaw detection, TLS employs black magnetic paste during MPI. This specific approach boasts high sensitivity in detecting even the smallest surface imperfections. The procedure comprises the following steps:

1. Application of Magnetic Levitation: A slow and controlled application of magnetic levitation over the workpiece prevents the washing away of magnetic imprints.
2. Utilization of Fixed Devices: Implementing fixed devices streamlines the process, ensuring ease of operation and high efficiency.
3. Demagnetization: This step reduces residual magnetism in the inspected workpiece, enabling subsequent processing or normal usage.
4. Removal and Drying: After the magnetic particle inspection, any residual magnetic levitation on the surface is removed and dried.

 
All our Quality Assurance personnel undergo rigorous certification examinations. At TLS, we uphold an unwavering commitment to product quality, delivering only after thorough confirmation that our offerings align with stringent quality inspection standards.
