Abstract
The need for fresh water on board a ship or offshore structure for passengers, crew, machinery and auxiliary uses has led to the high demand for fresh water. A cruise ship has the highest fresh water requirement compared with other ship types and as such the option of depending on natural source of water (rain) or collection from port is completely not feasible; accordingly, the production of fresh water on the ship is the only possible and convenient source. The fresh water requirement is determined considering the number of passengers, crew and other fresh water dependent machineries and auxiliary systems. The Reverse Osmosis process is chosen to be used for the fresh water production on the cruise ship, with membrane element selection done considering the element specification in relation to the expected fresh water production. The high pressure pump is selected to satisfy the feed flow rate required to produce the expected fresh water. Pre-treatment is carried out before the reverse osmosis process to remove solid particles and impurities, and post-treatment is done after the reverse osmosis process to improve fresh water quality. The membrane performance is calculated and results tabulated and discussed. The effect of changes in some parameters on the membrane performance is discussed and recommendations given.
