Low Sulphur Fuel Oil (LSFO)
Global compliance, superior performance, and reduced environmental impact for modern marine engines.
Introduction
Low Sulphur Fuel Oil represents a new generation of marine fuels introduced during 2019–2020. To comply with updated regulations aimed at reducing sulphur oxide (SOx) emissions into the atmosphere, this next-generation fuel, commonly referred to as Low Sulphur Fuel Oil (LSFO), is now widely adopted.
Benefits
-
Versatile Operation Designed for operation in both Main and Auxiliary engines.
-
Optimized Viscosity Main engine viscosity is higher than typically expected with DMA.
-
Thermal Safety Lower risk of thermal shock during fuel changeover, as ULSFO can be heated.
-
System Compatibility Performs effectively in segregated systems as well as single settling/service tank configurations.
-
Enhanced Lubricity Enhanced lubricity compared to DMA, reducing the requirement for additives.
-
Reliable Ignition Reliable ignition characteristics for consistent engine performance.
