Turbine systems are provided. In one embodiment, a turbine system includes a transition duct 50 comprising an inlet 52, an outlet 54, and a duct passage 56 extending between the inlet 52 and the outlet 54 and defining a longitudinal axis, a radial axis, and a tangential axis. The outlet 54 of the transition duct 50 is offset from the inlet 52 along the longitudinal axis and the tangential axis. The duct passage 56 includes an upstream portion 140 and a downstream portion 142. The upstream portion 140 extends from the inlet between an inlet end and an aft end. The downstream portion 142 extends from the outlet between an outlet end and a head end. The turbine system further includes a joint 160 coupling the aft end of the upstream portion 140 and the head end of the downstream portion 142 together. The joint 160 is configured to allow movement of the upstream portion 140 and the downstream portion 142 relative to each other about or along at least one axis. |
