- Abstract
This study presents a disassembly-based failure analysis of four high-capacity Sea Water Lift Pumps (SWLPs) and one Fire Water Pump (FWP) operating in long-term offshore service to quantify the synergistic degradation resulting from Cathodic Protection (CP) failure and hydro-abrasive wear. Inspection reports from multiple maintenance work scopes consistently show that severely worn, completely failed, or destroyed sacrificial anodes correlate directly with an accelerated rate of material loss in critical pump components. Quantitative analysis reveals significant impeller weight decreases, such as an average of 20% reported in one unit and substantial stage-to-stage weight differentials (4.7 kg to 6.95 kg). This empirical data demonstrates that the failure of CP initiates or accelerates corrosive attack, which, in turn, compromises the material's surface integrity, rendering it highly susceptible to the subsequent physical removal by hydro-abrasive media. The findings support a proposed data-driven model for mandatory anode renewal frequency, moving from run-time scheduling to a more effective condition-based strategy.
