TLS Offshore Containers: Revolutionizing the Oil Tank Container Industry with the T4 Tank Container

In the ever-evolving landscape of offshore and maritime logistics, the importance of reliable, safe, and efficient transportation of liquids, gases, and pressurized dry bulk cannot be overstated. At the forefront of this industry, TLS Offshore Containers is pioneering with its state-of-the-art T4 tank containers. These containers are not just containers; they are a testament to innovation, safety, and environmental stewardship in the transportation of hazardous materials across the seas.

**The Genesis of Excellence: T4 Tank Container Specifications**

The T4 tank container, a product of meticulous engineering and design, adheres to stringent international standards including the International Maritime Dangerous Goods (IMDG) Code, the American Society of Mechanical Engineers (ASME) VIII-1 for the construction of pressure vessels, and various ISO standards such as ISO 668, ISO 830, ISO 1161, and ISO 1496-3. This compliance ensures the T4 tank container meets the global criteria for safety, durability, and reliability.

With an overall dimension of 6058mm in length, 2438mm in width, and 2591mm in height, the T4 tank container boasts a gross weight capacity of 36,000 kg, a tare weight of approximately 4970 kg, and a maximum loading capacity of 31,030 kg. The container's volume is an impressive 30 cubic meters, optimized for the transport of a wide range of liquids and gases under the T code T4, signifying its versatility and capability to handle different types of dangerous goods.

The container operates within a design temperature range of -40°C to 130°C, ensuring it can withstand extreme conditions. Its design and test pressures are 1.77 Bar and 2.65 Bar, respectively, providing an additional layer of safety during transportation.

**Structural Integrity and Innovations**

At the heart of the T4 tank container lies its robust construction, primarily composed of the tank body frame assembly, spillage tray, walkway, bottom outlet valve box, and heating system, among others. The materials used, such as ASTM A240 304 for the cylinder and head plates, Q450NQR1 for the corner posts, and SPA-H for additional structural components, ensure durability and corrosion resistance.

The walkway, made of aluminum alloy, and the collapsible handrails and ladder, made of stainless steel, provide safe and easy access for inspection and maintenance. The innovative inclusion of a baffle with 18 holes of D100mm facilitates the stabilization of the cargo during transport, mitigating the risk of sloshing.

**Safety First: Advanced Features**

Safety is paramount in the design of the T4 tank container. It features two 2.5" BSP pressure-only safety relief valves set at 2.2 bar, with a negative pressure rating of 0.21bar, ensuring the container remains secure under varying pressures. Additionally, the container includes two manholes for easy access, an airline with a 1-1/2" ball valve, and both top and bottom outlet provisions for versatility in loading and unloading procedures.

The heating system deserves special mention; it comprises 12 stainless steel longitudinal steam heating tubes, providing an actual heating area of 7.5m2. This system ensures the contents can be maintained or brought to the required temperature, crucial for certain chemicals or oils that need to be kept fluid during transportation.

**Protecting the Environment and Contents**

Insulation and cladding are critical for maintaining the internal temperature and protecting the tank's contents. The T4 container uses 40mm thick rock wool insulation and is clad with 1.8mm thick glass-reinforced plastic over the barrel and 2.0mm thick over the ends, offering superior insulation and protection.

External surfaces are treated with a shot blast to SA 2½ grade and coated with a multi-layer paint system, including an epoxy zinc-rich primer, epoxy primer, and acrylic top coat, totaling 120 microns in thickness. This not only adds to the aesthetic appeal but also significantly enhances the container's resistance to corrosion and the harsh maritime environment.
