In
January 2002, Integrated Consultants & Engineers (ICE) working
as part of Dynamic Power Technologies was called upon by Siemens
Westinghouse Power Corporation (SWPC) to provide civil engineering
consulting services on an emergency, short-turnaround basis.
During final assembly of the Springs Industries, 50-year old
Unit #1 turbine-generator (T-G), SWPC field engineering personnel
determined that a gross misalignment at the Lower Pressure (LP)
Turbine to Generator coupling was a result of inconsistencies
in elevation between the various turbine supports. ICE personnel
provided immediate on-site assistance and determined that the
grout under the south-side LP support foot was deteriorated
and cracked to the extent that it permitted the support to settle
(change elevation). ICE then worked with SWPC and Springs Industries
personnel to optimize a process for lifting / supporting the
T-G, by combining the use of the overhead crane and power jacks
under the condenser feet, in order to provide the necessary
clearance for re-work of the grout pocket. ICE also then developed
a step-by-step procedure for removal of the existing grout and
placement of new grout. In the procedure, ICE dictated a change
to the grout pocket details and shimming to avoid future similar
problems. All grouting work was then carried out by the site
construction staff, the T-G coupling mated and the unit placed
back into service without further problems.
