When completing the ballasting operation of a contaminated tank, which of the following problems must be guarded against?

🔍 Key Concepts

• Ballasting contaminated tanks – what happens if dirty water is allowed to move the wrong way in the system • Flow direction and valves during stripping or final ballasting of a tank • Difference between equipment limitations (pressure, suction, overload) and pollution/control hazards

💭 Think About

• Ask yourself: which option could directly lead to spreading or re‑introducing contamination into other parts of the system or outside the vessel? • When you finish ballasting a contaminated tank, what is the most critical thing you must prevent through correct valve line‑up? • Which choices are normal operational issues, and which one is specifically a contamination/pollution control issue?

✅ Before You Answer

• Identify which choice is about flow direction of contaminated water, not just pump performance • Decide which problems would mainly affect efficiency or machinery, versus which could affect contamination or pollution • Before choosing, picture the piping system and valves when finishing a ballast evolution from a dirty tank and what could go wrong if wrongly aligned
