The Use of Controllable Pitch Propeller Systems by the Point Judith Fishing Fleet--A Feasibility/Cost Effectiveness Study.
Abstract
An analysis of three selected fishing vessels of the Point Judith fleet was conducted to determine the feasibility and cost effectiveness of replacing the current fixed pitch propeller systems with controllable pitch propeller systems The optimum amount of fuel saved through conversion to a controllable pitch system was approximately 17.4 to 19 per cent for the three vessels, and the cost of the systems could be paid back through these savings in periods of less than five years. Generally, the fishing vessel owners were interested in such systems and would like to see an actual retrofit on a fleet vessel. The current propulsion systems in use of three vessels of the fishing fleet (ranging in length from 64 to 87 feet) were examined. Then, a numerical and cost effectiveness analysis was accomplished based on a conversion of these vessels to a controllable pitch propeller system. Additionally, pay-back periods were computed based on installation of controllable pitch systems on comparable newly built vessels. Interviews were conducted with representatives of the controllable pitch manufacturers so that the marketing and sales philosophies could be examined. Finally, the owners of the three subject vessels were given exit interviews where the results of the study were discussed with each to determine their acceptance of such a system. (Author)
