A riser termination connects a steel riser duct to an I-tube or J-tube connecting interface of a floating unit, and includes an upper hang off portion, lower coupling adapter, steel termination conduit having an upper conduit end connected to the upper hang off portion and a lower conduit end connected to the steel riser duct. The termination conduit extends axially slidable through the coupling adapter. A circular cylindrical bearing seat is formed inside the coupling adapter and defines a bearing seat diameter, a bearing body having a bearing body diameter and protruding outward from the termination conduit inside the bearing seat. The bearing body diameter is smaller than the bearing seat diameter. A gap between the bearing body and the bearing seat allows relative sliding and rotation. The termination conduit includes a variable cross-section conduit portion having a diameter and wall thickness decreasing from the bearing body.
