Abstract: The Navy seeks to develop an insert for Navy ship chocks that will decrease the wearing and fowling of the current mooring lines and rigging equipment. Nelson Engineering Company proposes an innovative solution by developing a chock insert fabricated from Nylatronr NSM. This proposal discusses the requirements that a viable chock insert material must meet and how Nylatronr NSM either meets or exceeds these requirements. It also sets forth a detailed testing methodology and statistical result analysis that will be used to determine the degree of certainty to which the insert is likely to satisfy the requirements when installed in the field. Lastly, the proposal includes a discussion of the geometry and installation method that has been selected and will be optimized through the testing of a full scale prototype (fabricated in Phase I) in a future Phase II engagement.
Benefits: being secured to port. This insert will also be durable enough to withstand the corrosive marine environment and strong enough the force of the line under maximum allowable tension. These inserts will greatly increase the service life of mooring lines. Since the wearing of mooring lines is an industry wide problem and Nylatronr NSM can be easily molded to any shape, cast nylon inserts can be fabricated for all classes of Navy ships as well as all commercial and recreational vessels.
