Which Fuel at the Pump?

While both Marine Gas Oil (MGO) and Ultra Low Sulphur Fuel Oil (ULSFO) both meet the 0.1% sulphur limit for Emission Control Areas (ECAs), they are fundamentally different: Marine Gas Oil (MGO) is a pure, "clear and bright" distillate that behaves like high-grade diesel and is generally the most reliable and expensive option, requiring no heating but posing risks of low-viscosity leakage or "dry" injector wear. In contrast, Ultra Low Sulphur Fuel Oil (ULSFO) is typically a "hybrid" blend containing residual oil components, making it cheaper and more lubricious but technically complex, as it requires onboard heating to reach injection viscosity and carries a high risk of chemical instability or "sludging" if mixed with other fuels.Barry discusses a recent act of pilotage that he did where the choice between the two types of fuel may have made the main engine fluctuate and the Master forced to declare that he may have a problem. His hands-on current practice as a pilot allows him to give a unique perspective into the fuelling decisions being made in Northern Europe.Come and Visit our Website https://www.captainbarrysadler.com/At Captain Barry Sadler Maritime Training & Consultancy we deliver industry-leading online courses, oral exam preparation, and professional resources for deck officers, cadets, and maritime professionals.
