What kind of oil does this ship use?

Most ocean-going ships that open water passages between countries in the world are powered by fuel, because fuel is easier to store and transport and cheaper than coal. Residual fuel oil includes marine residual fuel oil RMD80, RME 180, RMG380, etc. Mainly used in low-speed diesel engines, or mixed with distillate fuel for low-speed diesel engines.

Steam turbines use heavy oil to burn boilers, because heavy oil is viscous and conducive to long-term combustion, while light oil (including gasoline). Diesel) is lean and has a high combustion temperature, but it won't last long.

Extended data:

Heavy oil is characterized by large molecular weight and high viscosity. The specific gravity of heavy oil is generally 0.82 ~ 0.95. Besides high viscosity, heavy oil has high sulfur content, metal content, acid content and nitrogen content. Heavy oil resources are huge, and the original geological reserves of heavy oil are about 863 billion tons.

Heavy oil is the residual heavy oil after extracting gasoline and diesel oil from crude oil, which has the characteristics of large molecular weight, high viscosity and non-volatility. The reason why heavy oil is used is because the Liaoning ship uses a steam turbine, which is relatively backward. Compared with other oil products, heavy oil has the characteristics of high temperature resistance, non-volatility, convenient transportation and storage, and is the first choice for cargo ships.
