SOME ASPECTS OF THE DESIGN OF DIESEL ELECTRIC ICEBREAKER PROPULSION SYSTEMS

Notes that propulsion systems in present use are subject to inefficient operation and possible failure of propellers, shafting or other system components because of unique loads imposed by the icebreaking process. This process is described and methods for calculating load torques are developed. The speed of advance of the ship through an ice field is taken as a performance index for the propulsion system and is used to derive a number of performance requirements. Methods are discussed which use steady and quasi-steady states and dynamic techniques for synthesizing a propulsion system which meets given performance requirements.
