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.

In the field of special containers—particularly those used on offshore platforms, vessels, and marine engineering facilities—compliance is not just a prerequisite for delivery, but a foundation for operational safety and system reliability. At TLS, we specialize in providing highly customized functional container solutions for global energy, petrochemical, and offshore clients. We understand that every detail must align with stringent international standards.
Core Compliance Framework
All offshore containers must meet the general safety requirements outlined by the International Maritime Organization (IMO) and the SOLAS Convention (International Convention for the Safety of Life at Sea). These regulations cover critical aspects such as lifting, stacking, fire protection, and emergency egress.
The ISO 10855 series provides technical specifications for offshore containers used in lifting and transportation, including structural strength, drop tests, and pad eye configuration. This standard is widely recognized across international offshore projects. In addition, TLS supports classification approvals from major societies such as ABS, LR, BV, and CCS to ensure compliance during sea transport and offshore deployment.
Special Requirements for Pressurized Explosion-Proof Modules
For functional containers used in Zone 1 or Zone 2 hazardous areas—such as electrical control rooms, testing cabins, or equipment enclosures—TLS offers pressurized explosion-proof modules certified to ATEX and IECEx standards. These certifications, accepted across the EU and globally, govern not only electrical components but also wiring systems, explosion-proof lighting, grounding, pressure relief, and alarm systems.
To achieve a higher level of system integrity, TLS incorporates IEC 60079-13:2020 into the design of pressurized rooms. This internationally recognized standard defines technical principles for constructing and operating pressurized enclosures in explosive atmospheres. It addresses overpressure maintenance, air tightness, emergency shutdown logic, and interlock protections. By embedding this standard into our design philosophy, TLS ensures that each module performs reliably even in scenarios such as fan failure, pressure loss, or gas intrusion.
Additional Relevant Standards
Depending on project scope and region, TLS solutions can incorporate a range of other industry-specific or regional standards. These include the EN 60079 series for general explosion-proof design, NORSOK standards commonly adopted in Nordic offshore projects, and the IBC Code for containers storing hazardous chemicals. Fire safety classifications such as A60 or B15 are often required for accommodation units, control rooms, or emergency shelters.
TLS Compliance Integration Capabilities
From lifting and transport containers, to intelligent pressurized systems with gas monitoring and automation, to offshore accommodation modules—TLS delivers with a focus on total compliance. We not only design and manufacture to required standards but also assist with third-party testing, documentation, and certification processes to ensure seamless project approval.
Conclusion
In offshore environments, safety, compliance, and reliability are non-negotiable. TLS remains committed to delivering containerized solutions that meet international certifications and adapt to the most demanding offshore conditions.
