Improving green fresh water supply in passengers ships using waste energy recovery

Abstract EN

The maritime industry is seeking sustainability solutions, Pressure at an international level has added a line item to the signature coding for each ship to now include their status on “green” criteria.

The ISO 30000 series standards cover ship recycling management systems, Green supply chain management (GSCM) has emerged as a key approach for enterprises seeking to become environmentally sustainable, especially in maritime transport sector which run 90% of the world trade.

Nation’s top freight transportation, the global supply chain management and the major ships designers gathered to provide the research, resources and education necessary to: The first, use less energy, including fuel and electricity, the second use less fresh water, plastic, paper and other consumables and the third reduce emissions that reduce the quality of its air.

The main objective of this paper is to enhance the overall performance of Marine Diesel Engine power plant on board passenger ships through a proposed fresh water generator and combined heat and power system which minimize the fuel emission and improve the maritime supply chain transportation network.

Fresh water produced will be used for drinking, cleaning and washing purposes contributing to the high demand consumption particularly on board passenger ships.

The main idea for proposed fresh water generator is to use the waste heat recovered from scavenging air to provide the heat required to evaporate sea water under vacuum converting it into steam.

Energy conservation system for exhaust gases in container ships has a lot of advantages which include, reducing fuel consumption for ships, increasing the overall efficiency, reducing the pollutant emissions which go out into the atmosphere, and saving lost money.

Which minimize the fresh water supply by 8 tons/day.

This amount will be sufficient for 20 persons per day.

For a number of diesel engines equipped with the proposed fresh water generator the specific fresh water generation was found about 100 gm/hp/h.
