The design is a sustainable and environmentally friendly system design for ocean-going ships. It is divided into two parts in total: one part is the design of electric power ecology using abundant wind energy and solar energy at sea; the other part is the renewable treatment of sewage and dirty water on ships.

The power source of the power generation system is mainly divided into three parts: wind energy, solar energy and mechanical energy generated by the crew during exercise. The ship has plenty of wind resources during the voyage. If the weather is right, solar energy is also sufficient. In addi- tion, during the investigation, we also learned that the crew has the habit of fitness, so the mechanical energy generated during fitness is also one of the sources of electricity. At the same time, the device has a modular design to adapt to more ocean-going vessels of different sizes.
