Cost Effectiveness Study of Wastewater Management Systems for Selected U.S. Coast Guard Vessels. Volume I. Results of Cost and Effectiveness Analyses and Selection of Optimum Candidate Systems
Abstract
A generalized methodology for quantifying the life-cycle cost and effectiveness of candidate system/vessel combinations, as well as optimum candidate selection procedures for choosing the most cost-effective system, have been developed and documented. In order to test this analysis methodology in a realistic environment, 18 candidate wastewater management systems (WMS) concepts in configurations suitable for handling black and gray wastewaters on board six U.S. Coast Guard cutters were developed. The 18 WMS concepts were synthesized as hybrid combinations of commercially available MSDs, namely, Jered, GATX, Chrysler, Grumman, and a CHT (Collection, Holding and Transfer) system. Mission profile data for each vessel were collected and analyzed to determine the mission profile characteristics which affect WMS design and operation. Detailed life-cycle and effectiveness models suitable for analyzing candidate WMS as a function of vessel were developed. Generic MSD cost and effectiveness data were generated. An installation analysis was performed to establish viable candidate system/vessel combinations and to develop required installation related cost and effectiveness data. Each viable candidate system/vessel combination was then subjected to a life-cycle cost and an effectiveness analysis. An optimum candidate system for each vessel as a function of holding time objective was determined. The results of these analyses are presented, together with conclusions and recommendations.
