  With the improved accuracy of neutron star observational data, it is
necessary to derive new equation of state where the crust and the core are
consistently calculated within a unified approach. For this purpose we describe
non-uniform matter in the crust of neutron stars employing a compressible
liquid-drop model, where the bulk and the neutron fluid terms are given from
the same model as the one describing uniform matter present in the core. We
then generate a set of fifteen unified equations of state for cold catalyzed
neutron stars built on realistic modelings of the nuclear interaction, which
belongs to two main groups: the first one derives from the phenomenological
Skyrme interaction and the second one from $\chi_{EFT}$ Hamiltonians. The
confrontation of these model predictions allows us to investigate the model
dependence for the crust properties, and in particular the effect of neutron
matter at low density. The new set of unified equations of state is available
at the CompOSE repository.
