Ensuring Peak Performance: Why Rigorous Testing Makes TLS Offshore Containers Stand Out

​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.
