A Phase 1 study was initiated by the Coast Guard RD Center to determine the feasibility of using composite materials to reduce the weight of the National Strike Force cargo transfer pumps. The Carderock Division of the Naval Surface Warfare Center CDNSWC was tasked to carry out Phase I. Initially all of the pumps in the Coast Guards inventory were investigated. The study eventually focused on one particular pump at the Coast Guards request, the CCN-150. A CCN-150 was obtained and disassembled by CDNSWC. Each of the major components was assessed as to the feasibility of fabricating it out of composite materials. A test plan for strain gaging and running the CNN-150 at a variety of operating conditions was proposed. Actual testing of the CCN-150 would provide an understanding of the operational strain levels in the pump. Three options were presented for a composite CCN-150. The risk and potential weight savings for each option were presented. CDNSWC recommended that a composite CCN-150 be pursued in two separate stages. First, the suction bell and pump bowl would be replaced by a composite version. This pump would then be evaluated. If the performance of the CCN-150 was not degraded by these new composite components and significant weight savings were demonstrated, work on a composite motor housing would be initiated. A CCN-150 with a composite suction bell, pump bowl, and motor housing has the potential for reducing the weight of a state- of- the-art stainless steel CCN-150 by 36.
