The original tank design faced safety and stability concerns, with issues related to geometry, insufficient thickness, and lack of structural reinforcement. These shortcomings risked the tank’s integrity under varying conditions.
Key modifications included adjusting the geometry by removing three base-frame channels, optimizing thickness parameters, and adding stiffeners. Inclined stiffeners were extended to the bottom plate, and two horizontal stiffeners were introduced in the taper tank. FE analysis using shell elements guided these changes, and a lifting lug was added to enhance stability during lifting scenarios.
The improved design ensured structural integrity and safety, meeting established standards. The optimized thickness and strategically placed stiffeners enhanced stability, while the lifting lug provided additional support for diverse operational conditions.
