In order for you to operate your vessels crude oil wash system, the cargo tanks to be washed must be which of the following?

🔍 Key Concepts

• Crude Oil Washing (COW) requirements under SOLAS and MARPOL • Purpose of an inert gas system (IGS) on tankers • Why controlling flammable vapor in cargo tanks is critical during washing

💭 Think About

• When you spray crude oil inside a cargo tank, what happens to the amount of vapor and the chance of ignition? • Which tank condition best keeps the oxygen concentration low enough to prevent combustion during crude oil washing? • Think about whether you would ever want people entering or tanks open to air while using a COW system, and why.

✅ Before You Answer

• Verify which condition keeps oxygen content below the flammable range in cargo tanks. • Confirm which option is specifically required by SOLAS/MARPOL when crude oil washing is carried out on oil tankers. • Eliminate any options that would increase ventilation with fresh air into the cargo tank during washing.
