Indentifikasi penurunan suhu pemanasan air lait di dalam evaporator fresh water generator (FWG) untuk keperluan di kapal lpg/c gas ares

Abstract

This study examines the decrease in seawater heating temperature in the Fresh Water Generator (FWG) evaporator on the LPG/C Gas Ship Ares, which results in decreased freshwater production. The purpose of this study was to identify the causes of the decrease in heating temperature and determine its impact on FWG performance. The research method used was descriptive qualitative, with data collection techniques including observation, interviews, documentation, and literature review. Data analysis was conducted using the Fishbone Diagram method to identify the root cause of the problem. The results showed that the decrease in heating temperature was caused by the formation of scale on the evaporator and leaks in the heating pipes of the Jacket Cooling Fresh Water (JCFW) system. This condition hampered heat transfer, resulting in suboptimal evaporation and decreased freshwater production. Efforts to address this problem included chemical cleaning of the evaporator and replacing leaking heating pipes.
