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.
