Fresh Water Generator is an aircraft that function change sea water into
fresh water through the process of evaporation and condensation. So hopefully
with this tool installed aboard the ship against dependence can reduce the supply
of fresh water from the land. However the fact the real level of high levels of salt
in the Fresh Water Generator affects freshwater productivity due to the process of
heating and cooling on the evaporator and condensor running slow and caused the
decline in the production of the freshwater.
The research was carried out against Fresh Water Generator, Alfa
Laval type HW HW80 Aqua on the ship MT. Enduro, one of a fleet owned by
PT. Pertamina.This done by the writer in the ship for the past 14 months when the
author implement the practice of sea. The source of the data used in the
preparation of this thesis includes primary data obtained directly from the place
of research, as well as secondary data obtained from the literature relating to the
title of the thesis. While the types of methods that writers use is Analisa SWOT,
which aims to determine the most influential factor in the causes of increased
levels of salt. Source data obtained directly from the boat is interview with the
head of the engine room as well as the documentation related to this research.
From this research, factors cause elevated levels of salts on freshwater
productivity is to adhere crust on the pipe evaporator and salt crust on the plate
evaporator heater and there is dirt in the form of mud on the cooling pipe of
condenser. Its effects on the freshwater production is declining. Efforts are being
made is to do maintenance on a regular basis, periodic and periodic inspections.
Key Word : Fresh Water Generator, Analisa SWOT, Evaporator
