SOLUTION
A decade later, our team performed a new erection of the steam turbine and the balance of the plant piping and equipment for the power plant.
The project included the installation of a 125-megawatt Mitsubishi steam turbine and generator, along with associated piping and equipment. The piping scope for the turbine consisted of 400 feet of carbon and stainless lube oil and hydraulic oil piping. In addition, we addressed the fuel gas compressor and related piping.
For the balance of the plant, fabrication and installation was completed including 5,200 feet of critical pipe, 25,000 feet of noncritical small bore pipe, 15,000 feet of noncritical large bore pipe and equipment erection. The critical piping system is made up of high-pressure steam, cold reheat steam and hot reheat steam. The noncritical systems included boiler blowdown, boiler feedwater, aux cooling water, fuel gas and circulating cooling water. In addition to balance of plant piping and equipment, AZCO installed a 70,000-pound compressor.
Furthermore, a fabrication shop was built on-site to more efficiently rebuild and replace pipe for the project, saving costs and time.
