SOLUTION
In June 2013, Empire selected Burns & McDonnell to make its vision a reality. In collaboration with partner AZCO, we served as EPC contractor and quickly went to work engineering the details of converting an existing Siemens V84.3A combustion gas turbine generator to a combined-cycle unit.
Our team procured a Siemens ST‑700/900 steam turbine generator (STG), a Nooter/Ericksen triple pressure heat recovery steam generator (HRSG), an SPX mechanical draft cooling tower and a range of other materials and equipment needed for the plant upgrade.
To fit the new combined-cycle unit in between the existing combustion turbine and the river that runs along the site, we worked closely with Empire and Riverton to compress the overall footprint of the unit. This strategy required significant crane planning and placement on the site, specifically to not obstruct or interfere with the operating unit and any exhaust emitted from the operating unit. To house the STG indoors, our team transported it from the south side of the site to the north before enclosing the building around it.
Our team collaborated with Empire throughout the entire project to discuss any issues. This allowed everyone to know the progress and situation of the projects, to be involved in the development of any solutions and to keep the project moving forward.
