1. An apparatus arranged to form a seal between an inner casing and a rotor, the apparatus comprising:
a plurality of seal segments, each seal segment arranged to define a partial arc that extends around a portion of a central axis of the rotor and includes a first hook having an open portion facing the central axis and arranged to engage a second hook coupled to the inner casing;
an alignment tool removably connected to the inner casing, the alignment tool including a partial annular ring that extends in an arc between 190 degrees and 350 degrees;
a plurality of jack bolt pairs movably coupled to the alignment tool, each jack bolt pair arranged to engage one of the seal segments of the plurality of seal segments to position the seal segment in a desired radial position with respect to the rotor; and
a plurality of fasteners arranged to removably connect each seal segment of the plurality of seal segments to the inner casing.
