In an impressed current cathodic hull protection system, what statement is true concerning the composition and arrangement of the anodes?

🔍 Key Concepts

• Difference between sacrificial anode systems and impressed current systems (ICCP) • Typical anode materials used in impressed current systems (think inert vs. consumable metals) • Whether ICCP anodes should be electrically bonded or insulated from the hull

💭 Think About

• Ask yourself: in an impressed current system, is the hull protected mainly by the anode metal wasting away, or by an external power source pushing current? • Which metals (zinc vs. lead/platinized titanium) are more likely to be used as long‑lasting, almost non‑consuming electrodes? • If the hull itself is the structure you’re trying to protect, should the current return path be through a direct electrical bond to the hull, or controlled via insulation and wiring?

✅ Before You Answer

• Verify which metals are commonly listed as sacrificial anode materials (for simple galvanic systems) versus as inert anodes (for ICCP). • Check whether impressed current anodes are designed to consume rapidly or to last a long time with minimal loss of material. • Confirm if standard ICCP diagrams show the anodes wired and insulated from the hull or bolted/bonded directly to it.
