  We study the two-dimensional disordered topological superconductor with
Hubbard interactions. When the magnitude of the pairing potential is tuned to
special values, this interacting model is exactly solvable even when disorders
are imposed on the potential term or coupling constants. The topology of this
model is investigated in detail by the real space Chern number formula, which
computes the topological index of disordered systems to high precisions. It is
found that the disorders can drive the system from topological trivial phase to
a non-trivial phase, which generalizes the topological Anderson phenomena to
interacting models. The self-consistent Born approximation is also employed to
understand the influence of the disorders on the parameters of the interacting
topological superconductor. It provide an alternative way to understand the
topological transitions at weak disordered region.
