Which fitting at the end of a cargo line allows suction to be taken close to the bottom of a tank?

• A. Vacuum valve
• B. Bell-mouth
• C. Strainer
• D. Suction end

Answer: (B)

The bell-mouth fitting is specifically designed to facilitate the suction of liquid from the bottom of a tank, allowing for maximum efficiency during cargo operations. Its distinct shape helps to minimize turbulence and ensure that the liquid is drawn in smoothly, which is crucial for effective pumping and reducing the potential for air ingress that can disrupt fluid flow. In addition to optimizing liquid flow, the bell-mouth fitting helps to reduce sediment resuspension by allowing suction very close to the tank bottom. This is particularly important in tanker operations because it ensures that the cargo being pumped is as clean and free from contaminants as possible, preserving the quality of the cargo. Understanding the role of this fitting is essential for the safe and effective handling of liquid cargoes on tankers, ensuring that unscheduled interruptions, spills, or damage to the cargo due to poor suction practices are avoided.
