Abstract:
This study discusses the optimization of the reliquefaction system in handling Liquefied
Petroleum Gas (LPG) cargo on board MT. Victoria Lyra. The background of this study
is based on the important role of the reliquefaction system in maintaining the stability of
cargo pressure and temperature during the loading process and throughout the voyage.
The reliquefaction system functions to convert gas vapor back into liquid form in order
to prevent excessive pressure increase inside cargo tanks, maintain cargo temperature
stability, and minimize cargo evaporation. The less optimal operation of the
reliquefaction system may cause an increase in cargo tank pressure and temperature,
which can disrupt LPG cargo handling operations.
This study aims to identify the factors causing the reliquefaction system to operate less
optimally in handling LPG cargo on board MT. Victoria Lyra and to determine the efforts
made to optimize the performance of the system. The Research method used in this study
is a descriptive qualitative method with data collection techniques through observation,
interviews, documentation, and literature study conducted during the author’s sea practice
on board MT. Victoria Lyra.
The results of the study indicate that the less optimal performance of the reliquefaction
system is influenced by several factors, including the less optimal operation of the cargo
compressor, ineffective cooling down process, increased ambient temperature, and
inadequate maintenance of supporting equipment in the reliquefaction system. The
impacts caused by these conditions include increased cargo tank pressure and
temperature, disruption of the LPG loading process, and decreased cargo stability during
operational activities.
Efforts made to overcome these problems include carrying out routine maintenance of the
reliquefaction system, improving monitoring of cargo tank pressure and temperature,
conducting periodic inspections of the cargo compressor and condenser, and enhancing
the coordination and understanding of officers and crew members regarding the operation
of the reliquefaction system. Based on the results of this study, it can be concluded that
the reliquefaction system has a very important role in maintaining the stability of LPG
cargo conditions so that the safety and smoothness of ship operations can be maintained
optimally.
