  We extend some convergence results on nonsingular compact Ricci flows in the
papers \cite{Ha:1}, \cite{Se:1} and \cite{FZZ:2} to certain infinite volume
noncompact cases which are "partially" nonsingular. As an application, for a
finite time singularity which is partially type I, it is shown that a blow up
limit is a gradient shrinking soliton.
