Abstract

Oscardi, Hardyansyah. 2025. "The Impact Of The Blockage Of The Main Condenser Cooling Pipe On The Steam Condensation Process On The LNG Ship EkaPutra 1” The main condenser is one of the crucial components in the cooling system of LNG/C Eka Putra1, which functions to condense steam from the steam turbine into condensate water. The efficiency of the condenser is highly influenced by the smooth flow of seawater as a cooling medium. This study aims to analyze the impact of blockage in the main condenser cooling pipes on the steam condensation process.The method used is a descriptive qualitative approach with data collection techniques through direct observation, interviews with the ship’s engineers, as well as literature study and documentation during sea practice. The results show that the drop in seawater pressure and the rise in condenser temperature are caused by blockages due to plastic waste, marine organisms, and scale caused by galvanic corrosion. These blockages disrupt heat transfer and reduce condensation efficiency.Handling efforts are carried out through the condenser backwash procedure and routine cleaning of cooling pipes, as well as optimizing the Marine Growth Prevention System (MGPS) to inhibit marine organism growth. The study concludes the importance of regular maintenance and proper operational procedures to maintain optimal performance of the main condenser and prevent disruptions to the ship’s main propulsion system.
