Abstract:

Various efforts are being made to achieve carbon neutrality with the aim of achieving net zero greenhouse gas emissions by 2050, and the shipping industry is also required to reduce carbon dioxide emissions. Heavy oil is the main power source for current large ships, which emits a large amount of CO2. Efforts are being made to supply some of the power and power used on ships with solar power. However, in the sea, where there are no tall structures, there is a high risk that lightning will strike the solar panels installed on large ships, making them unable to generate electricity. Thus, in order to protect the solar panels installed on large ships from lightning strikes, the methods and effects of installing lightning rods or overhead ground wires on large ships were investigated. As a result, it was found that installing overhead grounding wires on both sides of a ship is the most effective method, and the details of this study are reported.
