Experiments were performed where steel specimens were cathodically polarized in natural sea water by galvanic coupling through an external resistor to an aluminum anode. Temperature was either ambient or 5°C; and pressure was atmospheric or 8.96 +- 0.14 MPa (1,300 +- 20 psi), which is equivalent to a water depth of 899 m (2,950 feet). For some experiments, dissolved oxygen concentration was controlled...
Key words: Cathodic protection, sea water, deep sea water, design criteria, steel, galvanic anode, calcareous deposits.
