🔍 Key Concepts

• CAPAC system purpose on a ship (what is cathodic protection for?) • Relationship between corrosion, fouling, and paint condition on a steel hull • What changes when a steel hull goes from in-port to underway

💭 Think About

• Ask yourself: What is the primary job of a CAPAC (impressed current cathodic protection) system on a steel vessel? • If that system is OFF while the vessel is moving through seawater, which problems could reasonably increase: rusting of steel, marine growth, or damage to the protective paint? • Think about whether only one of those effects would occur, or whether more than one might logically follow from losing cathodic protection.

✅ Before You Answer

• Be clear on the main protection CAPAC provides (what is it actually designed to prevent?). • Consider how loss of cathodic protection might indirectly affect paint and fouling over time, not just immediately. • Before choosing, ask: Is this option consistent with the basic definition of cathodic protection, or is it describing something unrelated?
