• Major benefits of Shell’s ULSFO 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 Shell’s ULSFO can be heated
  • Relative ease of fuel handling with no major increase in crew workload when working with Shell’s ULSFO
  • 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
