The trials included numerous switchovers between ULSFO and higher sulphur fuels (LSFO 1%S, HSFO 3.5%S) and involved several engine types and tank/piping systems.
- Major benefits of Shell’s ULSFO n Shell’s ULSFO is designed to run in both Main and Auxiliary engines
- Viscosity at Main engine is higher than would beexpected 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
