Zusammenfassung:	A method is provided for modifying a turbine casing (404). The method includes providing one or more casing retention pin bores (414) in the turbine casing (404); inserting a retention pin in the one or more casing retention pin bores (414); providing one or more patch ring segments (402) configured to be radially constrained by at least a portion of the turbine casing (404) and further configured to slide circumferentially in cooperation with at least a portion of the turbine casing (404), wherein the one or more patch ring segments (402) comprise at least one retention pin locking bore (510); installing the one or more patch ring segments (402) in the turbine casing (404) to radially constrain the one or more patch ring segments (402); and engaging the retention pin in the at least one retention pin locking bore (410) to circumferentially constrain the one or more patch ring segments (402) to the turbine casing (404).
