Claim 7:
8. A method to provide a resid based fuel via blending with an initial compatibility and a longer term stability for marine fuel oil applications, the method comprising:
providing one or more fuel blend components to one or more tanks at a terminal;
determining, via a controller and based on signals from a corresponding sensor, one or more characteristics of the one or more fuel blend components;
determining, via the controller, a combination of the one or more fuel blend components, based on the one or more characteristics, to meet a fuel blend specification;
determining, via the controller, a sequence of addition for the combination of the one or more fuel blend components such that an aromaticity of each successive addition comprises an aromaticity of about 20% by weight of aromaticity of a prior addition or a mixture of prior additions;
transferring the one or more fuel blend components in the sequence of addition to a blend tank via a corresponding pipeline and one or more of a corresponding pump or corresponding valve, the corresponding pump and corresponding valve operated by the controller;
mixing, after each addition of the one or more fuel blend components, the added fuel blend components for a specified length of time; and
transferring the blended resid based fuel for use as a marine fuel oil.
