Low Sulphur Fuel Oil
What is it?
This is a new generation of marine fuel oils” (2019-2020). In order to meet new requirements for low sulphur oxide (SOx) emissions to the air, new generation of Low Sulphur Fuel Oil (LSFO) is being used.
Benefits
- Major benefits of LSFO is designed to run in both Main and Auxiliary engines
- Viscosity at Main engine is higher than would be expected with DMA
- Reduced risk of thermal shock during fuel switchover as LSFO can be heated
- Runs successfully in both segregated systems, and single settling/service tank environments
- Better lubricity when compared with DMA, reducing the need for additives
- Good ignition properties
