IFO 380 is a type of marine fuel oil commonly used in large ships and vessels. It is a heavy fuel oil that is derived from the distillation of crude oil and is characterized by its high viscosity and density. Due to its lower cost compared to lighter fuels, it is widely utilized in the shipping industry, particularly for commercial shipping operations. This fuel is often blended with other oils to meet specific performance and environmental standards. IFO 380 is subject to regulations set by organizations like the International Maritime Organization (IMO), which aims to reduce emissions and promote cleaner shipping practices.
