• Abstract:
  Washington State Ferries (WSF) has proposed an alternative of the propulsion engine lubricating oil (lube oil) filtration systems on ; some vessels in their fleet. Currently, WSF uses disposable cartridge filters for oil filtration on most vessels. Self-cleaning oil filters could be ; installed which would eliminate the need for disposable filter cartridge changes and might raise the particle removal efficiency. WSF began with ; a pilot installation on one of two engines on the M/V Chetzemoka in early 2014 and is interested in utilizing a three pronged perspective in their ; decision making on whether to install more of these filters in their fleet, considering operational performance, cost savings, and potential ; environmental benefits. These three perspectives are the focus of this research endeavor, with operational performance considered through lube ; oil analysis of samples taken from the M/V Chetzemoka, potential cost savings through a life cycle cost analysis (LCCA), and potential ; environmental impacts through a life cycle assessment (LCA) methodology. This report covers the first stage of this research effort: a background ; on lube oil analysis, a rough order of magnitude life cycle cost analysis of lube oil and the filtration alternatives, and an overview of environmental ; impacts of lube oil and some disposal methods through life cycle assessment methodologies. The preliminary LCCA shows that for a retrofit ; vessel such as the M/V Chetzemoka, cost savings would likely be achieved by installation of a self-cleaning filtration system, considering a 50 ; year life cycle. These savings would be even greater for installation on a new vessel. The environmental impact data assembled and modeled ; herein gives WSF a simple tool for approximating environmental impacts from an LCA perspective separately for acquisition and disposal by ; distillation. It can be applied directly to the filter problem, or in other capacities when oil use and disposal volume changes are involved. For the ; acquisition of lube oil, the most significant impact category with respect to US daily normalization per capita is Human Health Non-Cancer. For ; disposal through distillation to other products, the benefits gained from offsetting these products are always higher than the impacts of the disposal ; process. Future work is ongoing to gather more information on the oil analyses with the self-cleaning oil filter over extended periods. With this ; additional information, the work herein will be updated. For the environmental analysis, future work might relate the gallon functional unit to ; different functional units relevant to WSF operations such as passenger/vehicle capacity, etc. Additional future research could be to expand the ; analyses to consider other vessels in the fleet.
