The stationary multipartite entanglement between three interacting harmonic oscillators subjected to decoherence is analyzed in the largely unexplored non-equilibrium strong dissipation regime. We compute the exact asymptotic Gaussian state of the system and elucidate its separability properties, qualitatively assessing the regions of the space of parameters in which fully inseparable states are generated. Interestingly, the sharing structure of bipartite entanglement in the ground state is seen to critically depend on the dissipation strength. We also find that establishing stationary energy currents across the system does not correspond with the build-up of biseparable steady states, which relates instead just to the relative intensity of thermal fluctuations.
