🔍 Key Concepts

• Impressed current cathodic protection (ICCP): how it works and what parts of the ship it affects • Difference between hull/underwater metal protection and protection of machinery exposed to air • Whether ICCP has anything to do with electrical load management or magnetic fields

💭 Think About

• Think about which parts of the ship are actually in the seawater and are part of the same electrical path as the hull. • Consider whether cathodic protection systems interact with navigation equipment like radar or magnetic fields at all. • Ask yourself which options describe corrosion or oxidation in seawater versus functions that are unrelated to corrosion protection.

✅ Before You Answer

• Which answer choices mention underwater metal components that are electrically connected to the hull? • Which options talk about radar, magnetic fields, or electrical loads—do those have any real link to cathodic protection systems? • Confirm that the purpose of ICCP is still about corrosion control in seawater, not about air oxidation or power-plant operating conditions.
