The dredging system is a major subsystem of the Production Suction Dredger (KIP) that significantly affects mining operational continuity. This study aims to identify maintenance priority components based on historical failure data and determine component priorities using Pareto analysis as a basis for developing maintenance strategies. A quantitative descriptive method was employed using historical failure data of the KIP 07 dredging system during 2025, including failure frequency and downtime records. The data were analyzed using Pareto analysis based on each component's downtime contribution and subsequently validated through practitioner confirmation. The results revealed 104 failure incidents with a total downtime of 700.5 hours. Six priority components—pump bearing block, pump joint shaft, cutter bearing block, suction pipe, discharge pipe, and ladder—accounted for 80.87% of the total downtime. These findings provide a practical basis for prioritizing inspections and developing more effective maintenance strategies.
