Transporting of LPG vessel require spesific handling so that cargo tank is well
prepared to be loaded. So it is need to know how to handle pressure and
temperature of cargo tank in loading and effort to overcome these obstacle. As for
the basic theory states that LPG in atmospheric pressure will evaporate in very
low temperature, they are -42.30C for propane -0.50C for butane. Therefore
pressure and temperature in cargo tank must be in stable to maintain LPG in
liquid.
In this paper, writer use qualitatif methode, and collecting data by
observing object directly, interviewing a number of respondents and supported by
documentation method. According to the result of research, in handling
temperature dan pressure of cargo tank are carried on by running sloshing system
to prepare cargo tank because high pressure, make cargo tank well prepared to be
loaded, keep attention of temperature and pressure changes in cargo tank in
loading. While constraints of vopour residu from port that have been
contaminated with the other cargo and less optimal performance of sloshing
System due to interfence on cargo compressor. So the efforts to overcome it by
communicating with mother ship officer soon to prepare cargo compressor and
starting sloshing system.
In the end of researching about handling of pressure and temperature in cargo
tank is important to acheive a purpose (to expedite loading of LPG) and may be
taken responsibility then may be taken a conclusion or as evaluation for
refference.
Key word: Sloshing System, temperature and pressure of cargo tanks, loading
