1. A method for replacing a sliding pad of a rotational sliding bearing, wherein the bearing comprises a plurality of sliding pads each supporting an annular rotatable part of the bearing on a stationary part of the bearing in an axial direction and/or a radial direction, the method comprising:
removing a load of the annular rotatable part from the sliding pad to be removed by releasing a force applied to the sliding pad and/or by applying a force to the annular rotatable part;
removing the sliding pad in the axial and/or the radial direction;
inserting a replacement sliding pad, and
supporting the annular rotatable part on the replacement sliding pad by applying a force to the replacement sliding pad and/or by removing the force applied to the angular rotatable part;
wherein the stationary part comprises a plurality of axial and/or radial openings arranged circumferentially and/or axially displaced in the circumference of the stationary part, and the plurality of sliding pads are removable and/or insertable through the plurality of axial and/or radial openings;
wherein the stationary part is annular, wherein the annular rotatable part is arranged on an outer circumference of the stationary part, wherein the annular rotatable part is supported on the stationary part by the plurality of sliding pads in the radial and/or the axial direction, wherein the sliding pad is replaced from an interior of the stationary part.
