Abstract
A method of assembling a turbine casing is provided. The method includes inserting a bolt assembly through a first opening defined generally vertically through a first flange extending from a first casing member, such that a portion of the bolt assembly extends a distance upward from an upper surface of the first casing flange and such that the bolt assembly is retained within the first opening. The method further includes positioning a second casing member including a second flange including a second opening defined therein against the first casing member such that a portion of the bolt assembly extends through the opening defined in the second casing flange.
