You are planning to use the crude oil washing system on your tankship. What is required to prevent electrostatic buildup in the tanks?
AI Explanation
The correct answer is B) The source tank for the tank cleaning machines must have least one meter decanted from it.
The key to preventing electrostatic buildup during crude oil washing is to maintain a properly decanted source tank. This allows the suspended solids and water to settle, reducing the chance of creating a charged mixture that could lead to dangerous electrostatic discharge. The other options are incorrect - operating fixed and portable machines simultaneously, setting specific drop rates, or controlling the inert gas oxygen content are not the primary requirements for preventing electrostatic buildup in this case.
