Book Description
This report discusses a digital computer dynamic simulation program for a vessel with a diesel-electric propulsion system. The mathematical formulation of the problem is fully developed and the computer program used to solve the equations is presented. A comparison of the computer simulation predictions of key variables during maneuvers of the USCGC GLACIER and actual oscillograph recordings of these same variables is presented. The correlation between predicted and measured values is good and it is concluded that the simulation program will be an effective tooling in analyzing the performance of new icebreaker designs.

Book Description
This report discusses the simulation of a diesel electric propulsion system for an icebreaker using AC generators and rectified DC for the propulsion motors. A comparison is made between an icebreaker using this system and one using a more conventional electric propulsion system. (Author).

Book Description
A feasible design of the main propulsion system for the M-13 icebreaker is presented in this final report of a four phase study. Procedures are described that were used in meeting given performance specifications covering open water and icebreaking, operations and maneuvers. The automatic controls necessary to meet the performance specifications are developed. Results of the steady-state design analysis and dynamic performance analysis are presented, and an overall evaluation including major conclusions is included. (Author).

Book Description
This program solves numerically the set of simultaneous non-linear differential equations which describe the dynamic behavior of the complete propulsion system (including vessel dynamics) of a diesel-electric icebreaker during maneuvering. The program also contains a means of subjecting the propeller to ice impact loadings of the user's making. At the option of the user, input data can readily be printed for documentation purposes and output data can be plotted. (Author).

Book Description
This phase of the Icebreaker Propulsion System Simulation reports on the results of studies directed at improving the overall in-ice icebreaker performance through improved propulsion system design. A mathematical description of the ice-torque problem for dynamic and quasi-steady state behavior is presented, and additional propulsion system electrical circuit dynamics necessary to more adequately describe propulsion system dynamic behavior during propeller-ice encounters are described. The predicted performance of the USCGC GLACIER when subjected to the ice load torque model is presented. A load control scheme (designed to extend the constant horsepower range of the propulsion system well below bollard propeller speed) is developed and incorporated into the basic system equations. The performance of a system of the same size as the GLACIER incorporating this load control system and subjected to the same ice loads is also presented. It is concluded that the incorporation of a load control system significantly increases the capability of the icebreaker propulsion system when operating in ice. (Author).
