What does MDO stand for in maritime terminology?

Marine Diesel Oil (MDO) is a specific type of fuel used in the maritime industry, particularly in large vessels that rely on diesel engines for propulsion. This term encompasses a diverse range of fuel types, generally derived from the distillation of crude oil, and is formulated to meet the operational needs of marine engines.

MDO is designed to have properties that make it suitable for marine applications, including a certain viscosity and sulfur content that conform to international regulations and guidelines for environmental compliance. The use of MDO is important for ensuring efficient combustion and reduced emissions, making it a common choice among ship operators.

While Medium Distillate Oil may seem similar and often overlaps in meaning, the specific industry acknowledgment of Marine Diesel Oil makes it the correct term in this context. The other options, such as Marine Defense Oil and Multi-Duty Oil, do not represent established terminology within the maritime fuel classification systems, further solidifying the appropriateness of Marine Diesel Oil as the definitive answer.
