Pagination or Media Count:
This report investigates the feasibility of using impermeable membranes to permit the dual purpose use of cargo tanks in commercial vessels as clean water ballast tanks. Both engineering and economic assessments were made of the membrane method of isolating cargo and ballast in a common tank. The investigation included model tests, membrane material studies, ship structural analysis and a patent search of related membrane applications. Both new and converted existing tankers were considered in the study. Conversion costs and percentage increases i required freight rates are given. Additionally, the cost effectiveness in terms of dollars per cubic meter of operational and accidental pollution prevented are reported.
