May pollute the environment.
When the ship is moored at the quay, current regulations do not allow the use of the ship's own electricity generation system to avoid polluting the coastal environment. It must be connected to a variable frequency shore power supply for electrical supply. Usually, the variable frequency shore power used on the terminal only powers the terminal, so the shore power capacity is generally less than 3000 KVA per unit.
The pier, also known as the ferry, is a long embankment extending from the shore to the water. It can also simply be a row of stairs extending from the shoreline down to the water. -built civil engineering buildings, or they can be formed naturally.
The use of electric propulsion systems for ships is not minimal, but it is difficult to see thatElectric propulsion systems are mainly used in submarines, while surface ships are mainly used in internal combustion engine propulsion systems. The combustion engine generates power and can drive the propeller through the output shaft to directly push the ship forward, while the electric propulsion system also needs to add a set of production equipment. energy between the internal combustion engine and the propeller from the point of view of energy saving. , gain exceeds gain and is inefficient
