  Due to the difficulties present in experimentally preparing genuine
tripartite entanglement, it is important to explore the possibility of multiple
usage of a single genuine entangled state. In the present paper, we present one
such possibility by considering a scenario consisting of three
spin-$\frac{1}{2}$ particles shared between Alice, Bob and multiple Charlies.
Alice performs measurements on the first particle, Bob performs measurements on
the second particle and multiple Charlies perform measurements on the third
particle sequentially and independently. In this scenario, we investigate
whether more than one Charlie can detect genuine tripartite entanglement, and
we answer this question affirmatively. In order to probe genuine entanglement,
we use correlation inequalities whose violations certify genuine tripartite
entanglement in a device-independent way. We extend our investigation by using
appropriate genuine tripartite entanglement witness operators. Using each of
these different tools for detecting genuine tripartite entanglement, we find
out the maximum number of Charlies who can detect genuine entanglement in the
above scenario.
