In contrast to finite time singularities of Ricci flows, it is known that collapsing with bounded sectional curvature may occur as we approach time infinity along immortal Ricci flows. In this talk I will show that along an immortal Ricci flow with uniformly bounded diameter and sectional curvature, an unbounded sequence of time slices sub converges to a Ricci flat orbifold.
