**2.5 Pump to hull**

Although it is necessary to find and compare diesel ships of similar specifications as LNG vessels, it is difficult to obtain information on the number of days of sailing, sailing distance, ship weight (including load weight), fuel consumption, and electricity consumption for a certain period required for calculation. There are three types of marine-fueled vessels that are bulk carriers, oil tankers, and container ships. At the time, GREET only provided specifications of these ships. We average the total energy use and greenhouse gases to calculate data in the operation step. The information related to ships using LNG as fuel is not explained. Therefore, we get data from a company that operates LNG ships in South Korea.
