What is fuel oil blending?
Blending is a process for mixing two or more residual fuel oils and/
or distillate fuel oils to achieve a specific end product defined typically by reference to ISO 8217, IFO and viscosity, sulphur content or
other parameters. In practice, all bunker fuel is blended at one or
more stages of its journey from refinery to ship, occasionally with
material that is not suitable for use as bunker fuel; usually but not
invariably, such contamination is uncovered by laboratory analysis
of delivery samples.
