Abstract

Shipping company operates ships on the sea and pursues profits by producing and selling maritime transportation services for freight charges. Therefore, in order for a shipping company to survive, realize profits, and keep growing, it must minimize the costs of ships which are its production facilities. In other words, it is very important to decide when to replace the facilities after buying them to minimize the costs on facilities while fulfilling its required functions.

The purpose of this study is to determine the optimum timing for ship replacement by estimating the economic life of ships through the comparison between the increase of operation costs due to aging ships and the capital recovery according to the depreciation of ships.

Accordingly, this study established an analysis procedure for ships' life cycle cost based on the general studies on life cycle cost, established a ship cost breakdown structure, and proposed a life cycle cost evaluation model appropriate for effectively predict and manage a ship’s life cycle cost.

Besides, this study estimated the economic life cycle and life cycle cost of the two training ships which are used for students’ navigation practice in “H” University by predicting the capital recovery costs and annual equivalent operation costs.
