← ScienceWhich outcome accelerates in an offshore oil pipeline due to seawater?
A)Increased galvanic anode corrosion rate✓
B)Enhanced cathodic protection effectiveness
C)Decreased hydrogen embrittlement
D)Reduced uniform metal loss amount
💡 Explanation
Increased galvanic anode corrosion occurs because chloride ions facilitate electron transfer via electrolytic conduction, promoting oxidation. This amplifies the rate of depletion of sacrificial anodes, therefore reducing the pipeline's lifespan, rather than improving cathodic protection.
