This study employs the Faddeev formalism in configuration space to investigate the Ω3cNN cluster containing a triply charmed Omega baryon (Ω3c). Using the recently reported HAL QCD S-wave Ω3cN potentials in the 3S1 and 5S2 channels, together with the MT-I--III nucleon--nucleon potential and neglecting the Coulomb force, we find no bound state for the Ω3cnp system. We predict near-threshold resonances in the Jπ=5/2+ (maximal total spin) and Jπ=1/2+ (minimal total spin) states, with resonance energies of 1.1~MeV below and 0.0~MeV at the three-body breakup threshold, respectively, at Euclidean time t/a = 16. A similar analysis of the Ω3cΩ3cN system likewise reveals no bound states, though a possible resonance is indicated. The short-distance behavior of the HAL QCD Ω3cN potential is also discussed.
