Abstract:
The Fresh Water Generator (FWG) is a critical piece of equipment on a ship that converts
seawater into fresh water to meet the needs of the crew and ship operations. On the MT.
PETROSAMUDRA, a decline in fresh water production was observed, which has the
potential to disrupt operations on board. This study aims to identify the factors causing
the decline in fresh water production and to find solutions to restore the FWG’s
performance to optimal levels. Based on field observations and analysis, the decline in
freshwater production was attributed to insufficient steam pressure from the auxiliary
machinery, suboptimal vacuum conditions, scale buildup on the heat exchanger, and high
salt content in the seawater. Measures that can be taken to restore freshwater production
include routine maintenance such as cleaning heat exchangers, inspecting vacuum
pumps, and properly controlling temperature and pressure so that the ship’s freshwater
needs can be adequately met.
