High Frequency Non-Abrasive Propeller Cleaning System Navy SBIR FY2011.2 Sol No.: Navy SBIR FY2011.2 Topic No.: N112-157 Topic Title: High Frequency Non-Abrasive Propeller Cleaning System Proposal No.: N112-157-1251 Firm: Scientific Applications & Research Assoc., Inc. 6300 Gateway Dr. Cypress, California 90630-4844 Contact: Greg Raith Phone: (714) 224-4410 Web Site: www.sara.com Abstract: An efficient use of one's time benefits the whole. The U.S. Military's current method of cleaning their naval fleet's propellers is a laborious task; often requiring a multitude of hand tools, as power tools are often prohibited due to the risk of abrading the propeller's unique surface. This not only puts the fleet out of service during this time, but the cost associated with it trickles down to the taxpayer. Inefficiency is the issue. However, the inefficiency of the current method, and the associated costs that go with it, can be significantly reduced by the use of a High-Frequency Non-Abrasive Propeller Cleaning System. This system utilizes high-frequency oscillations that cut thru, parallel to the propeller's surface, and removes the ocean fouling without damaging the propeller itself. The result is reduced time: an increase in operator efficiency, a reduction in cost and the fleet going back into service faster. Benefits: Benefits of a High-Frequency Non-Abrasive Propeller Cleaning System are vast for a number of reasons. First, the automation of removing ocean fouling reduces the work load placed on the operator. Minimizing fatigue in an underwater environment is a significant improvement in operator safety. Secondly, the increased cleaning efficiency of such a system reduces the amount of time a ship or submarine remains out of service. Additionally, the reduction in cleaning time reduces the associated labor costs. Lastly, the overall cleaning process is simplified by reducing the number of tools required to obtain a properly cleaned propeller. The commercial applications of a High-Frequency Non-Abrasive Propeller Cleaning System are significant since such a device does not currently exist on the market. A device like this will revolutionize the current methods employed by the Navy for propeller cleaning of their fleets. Similarly, the private and commercial industries, ranging from personal water craft to cruise ships and commercial fishing fleets will benefit from the increased efficiency in cleaning propellers - reducing cleaning times, reducing labor costs and increasing fuel efficiency. And with the flexibility of this device being able to adapt to various surface contours, it can easily transition into an efficient hull cleaning tool. Return
