Main Diesel Engine Selection for Ships Based on Life Cycle Costing

Abstract

In order to obtain optimum decision making in selecting main diesel engine for ships, the life cycle cost technology is proposed. The breakdown structure and calculation model of life cycle cost for main diesel engine of ships are established. Taking a specific selection for main diesel engine of one ship as the instance, the purchase cost and life cycle cost for three types of main diesel engine are compared and analyzed. The type of main diesel engine is selected based on the calculation result of life cycle cost. The instance shows that the life cycle cost technology is a powerful decision-making tool, which is worthy of popularization and application in ship design and development stages.
