Analisis Teknis dan Ekonomis Hychain Shiplift 1500 Ton Divisi Kapal Perang PT PAL Indonesia

This study examines the technical and economic condition of the 1,500-ton Hychain Shiplift facility at PAL Indonesia Ltd., which has operated for more than 44 years. This research applies qualitative field observation methods, using failure mode and effects analysis (FMEA) in technical studies, as well as life cycle cost (LCC) calculation in its economic analysis. The findings show that lifting cylinder height deviations mainly result from solenoid valve failure, piston seal leakage, and corrosion in the hydraulic pipes. The FMEA highlights the control panel and cooling pump as the most critical compon ents requiring priority attention. From an economic perspective, the facility requires an initial repair cost of IDR 179.58 million, while the total present value of maintenance costs over the next ten years is estimated at IDR 249.6 million. In conclusion, upgrading the conventional control system to a PLC-based system represents a necessary retrofit strategy to ensure the operational reliability of the asset.
