  Simulations in which a globular ring polymer with delocalized knots is
separated in two interacting loops by a slipping link, or in two
non-interacting globuli by a wall with a hole, show how the minimal crossing
number of the knots controls the equilibrium statistics. With slipping link the
ring length is divided between the loops according to a simple law, but with
unexpectedly large fluctuations. These are suppressed only for unknotted loops,
whose length distribution shows always a fast power law decay. We also discover
and explain a topological effect interfering with that of surface tension in
the globule translocation through a membrane nanopore.
