A study for composing of the environmental-friendly propulsion system of tugboat.

为了减少拖轮对环境的影响，对混合拖轮系统进行了研究。有必要假设混合动力系统与传统系统相比是如何变化的，以及燃料消耗趋势的变化。然后，将基于系统数据的数据库作为后台，建立拖轮油耗模型。因此，现在可以进行各种系统的拖轮燃油消耗趋势的仿真。通过使用这种仿真，可以创建用于考虑混合系统优化的基础数据。

The system of the hybrid tugboat was examined for the purpose of the reduction in the environmental impact of a tugboat. It is necessary to presume how a hybrid system is compared with the conventional system and a fuel consumption tendency changes. Then, the fuel consumption model of the tugboat was built by making the data base based on system data into a background. Thereby, the simulation of the fuel consumption tendency in the tugboat of various systems can be carried out now. By employing this simulation, the underlying data for considering optimization of a hybrid system can be created.
