Abstract:
This research aims to analyze the causes of high LNG cargo temperature received from
the terminal and to identify factors contributing to the lack of knowledge and competence
of the crew in managing the cargo handling system on board LNG/C Lady Eva. The
research was conducted during the author's sea training on board LNG/C Lady Eva from
August 2, 2024 to August 6, 2025. The research method applied was descriptive
qualitative approach. Data were collected through direct observation, interviews,
documentation, and literature studies. The findings indicate that the high temperature of
the LNG cargo received was caused by suboptimal execution of the arm cooldown, line
cooldown, and tank cooldown procedures, as well as the high ambient temperature in the
Bontang area averaging ±37°C. These conditions accelerated the vaporization of LNG
cargo inside the tanks, causing pressure to exceed the compressor's capacity and
ultimately resulting in a vent out incident. Furthermore, the limited practical experience
of the newly appointed Cargo Officer and insufficient familiarity with the mosstype-type
vessel's cargo handling system led to delayed decision-making during the emergency.
The selected solutions include halting the loading process and coordinating with the
terminal to transfer LNG at a lower temperature, as well as providing structured and
periodic shore-based training supplemented by an on-the-job training program using the
one-to-one coaching method on board.
