Simulation Analysis of Automatic and Quickened Manual Control during Underway Replenishment.

Abstract

This final report summarizes the final results and conclusions of a program to define and analyze the control parameters affecting the dynamic interactions between two ships during Underway Replenishment (UNREP) and to make recommendations for a prototype ship separation monitoring system. Results of hybrid computer simulations of UNREP by two identical, Mariner class ships, including consideration of nonlinear maneuvering equations, regular waves, severe first- and second-order irregular-wave excitations, time-sampled separation measurements, and low-pass filters, are presented. Contrary to earlier assumptions, first-order irregular-wave excitations were found to dominate the UNREP control problem. Use of either automatic or quickened manual control was found to be feasible, but work is needed to define the capabilities and limitations of quickening in this application. Recommendations for development of a prototype ship separation sensing system are presented. (Author)
