One of the factors causing the performance of Fresh Water Generator is not optimal, among others, a blockage in the seawater system on Fres Water Generation and Generation maintenance is not carried out immediately. Hence the need for handling the work factor of Fresh Water Generator is not optimal in producing fresh water on board.
With proper maintenance on each component Fresh Water Generator as well as proper operation in accordance with the Instruction Manual Book contained in company does not lose and vessel operations can run on schedule. At the end part of this thesis, author present conclusions and suggestions. To overcome the problems that occur and give suggestions to carry out regular maintenance and periodic according Instruction Manual Book.
