What are liquid-tight separations between compartments in tanks referred to as?

1. Partitions

2. Barriers

3. Bulkheads

4. Walls

The correct answer is: Bulkheads

In the context of tanker design, liquid-tight separations between compartments are referred to as bulkheads. Bulkheads serve the critical function of preventing the movement of liquids between different compartments within a tank. This is especially important for ensuring stability and controlling the flow of liquids during transport, as well as mitigating the risks associated with spillage and leakage. Each compartment can contain a different type of liquid, and bulkheads help maintain these separations to prevent mixing. In addition to enhancing safety and stability, they can also increase the structural integrity of the tanker by providing additional support against the forces exerted by liquefied materials inside the tank during transportation. The use of bulkheads is a fundamental aspect of tank design in compliance with safety regulations for transporting hazardous materials.
