ANALISIS DAMPAK CLOGGING OLEH SEA BUTTERFLIES TERHADAP EFISIENSI TERMAL SISTEM REGASIFIKASI LNG DI FSRU JAWA SATU

Abstract

This study comprehensively examines the serious impact of clogging caused by sea butterfly (Pteropoda) populations on the thermal efficiency of the LNG regasification system at the Floating Storage Regasification Unit (FSRU) Jawa Satu. Clogging occurring in the sea cheststrainer and heat exchanger significantly reduces the operational efficiency of FSRU by impeding the flow of seawater essential for the glycol heating process. Consequently, the efficiency of the LNG vaporiser decreases, which not only affects the performance of the regasification system but also potentially disrupts the stability of gas supply to power plants and industries. The research method used is descriptive qualitative, with data collected through direct field observations, ship operational documentation, and in-depth analysis of operational data. The results of this study clearly demonstrate that clogging has a significant impact on reducing the efficiency of the regasification system, which not only affects the operational performance of FSRU but also potentially disrupts overall energy supply stability. To address this issue and maintain operational sustainability, this study recommends the implementation of a periodic and comprehensive marine ecology monitoring system, optimization of the existing anti-fouling system, and development of effective marine bioorganism management strategies. These strategies are expected to maintain the operational efficiency of FSRU in a sustainable manner and reduce the risk of energy supply disruptions caused by sea butterflies. This research also highlights the importance of awareness regarding ecological changes affecting marine populations and the need for proactive measures to protect energy infrastructure from biological impacts.
