OPTIMALISASI PROSES PURGING PADA MANIFOLD TERHADAP KETEPATAN WAKTU UNLOADING CARGO PADA KAPAL LNG/C ST. EKAPUTRA 1

Abstract

The purging process at the manifold is a critical stage in LNG cargo unloading operations aboard the LNG/C ST. Ekaputra 1. This process aims to remove residual LNG from the pipeline before disconnecting the arms, ensuring both crew safety and operational efficiency. This study was prompted by delays observed during the purging phase, particularly at PGN FSRU Lampung, where operations took longer than at other terminals. The research aims to analyze the factors affecting purging efficiency, including the quality and pressure of nitrogen (N₂) and the skill and coordination of the ship’s crew. A qualitative descriptive approach was applied, utilizing data collection methods such as observation, documentation, and interviews conducted during onboard training. The results revealed that inadequate nitrogen pressure and poor crew communication were the main causes of extended purging duration. To address these issues, the study recommends regular maintenance of the N₂ generator, periodic crew training, and the development of more detailed and clear standard operating procedures (SOP). This research is expected to contribute practically to LNG cargo handling operations, improving both safety and turnaround time during port stays.
