Non-Abrasive Propeller Cleaning System Navy SBIR FY2011.2 Sol No.: Navy SBIR FY2011.2 Topic No.: N112-157 Topic Title: Non-Abrasive Propeller Cleaning System Proposal No.: N112-157-0847 Firm: Enigmatics, Inc. 9215 51st Avenue Unit No. 7 College Park, Maryland 20740-1949 Contact: Hunter Greene Phone: (301) 486-1725 Web Site: enigmatics.com Abstract: This Small Business Innovation Research Phase I Project focuses on the development of an innovative method biofouling removal from the surface of propellers. The proposed method is non abrasive and will not lead to damage of propeller surface edges. In Phase I Enigmatics will demonstrate feasibility of the proposed cleaning technique. Phase I option will focus on design of cleaning system that will be demonstrated in Phase II, a system scalability study, as well as preparing biofouled samples to be used in Phase II. The proposed technology will be used to provide an environmentally friendly, low cost and effective method for cleaning Navy propellers. The Phase I research will be to gain a full understanding of concept capabilities and limitations in order to accurately assess process economics and system advantages. Benefits: Proposed efficient methods of propeller cleaning, when developed, will have a significant impact on Navy operations. Currently ~$100M a year is attributed to cleaning ships in order to reduce drag caused by fouling. Approximately 50% of the fuel saving that is attributed to cleaning is directly related to the cleaning of propellers and shafts. Thus effective cleaning methods will reduce the cost of cleaning operations, allowing more frequent cleaning and leading to fuel savings from more efficient operation. Return
