Project Profile
Simpson Tacoma Kraft Cogeneration Project Tacoma, WA
 
Simpson Tacoma Kraft has contracted JH Kelly to be the contract lead during the construction of its new Cogeneration Project. The project involves the installation of a new steam turbine generation set, exhaust steam condenser, cooling towers, power distribution switchyard, associated equipment and all steam, feedwater, cooling water and other related piping systems. A new turbine hall will be constructed on a site that was previously occupied by an old power house. As part of JH Kelly's work scope, we have also been contracted to perform miscellaneous engineering assistance, constructability reviews, and provide value engineering options that will decrease costs, minimize paper maching down times and improve existing piping and mechanical existing systems. JH Kelly was hired to perform this project due to our understanding and experience in working in an existing facility. Many of the piping systems require us to work around sensitive machinery and piping with very little access. Piping sizes range from 2" to 30". Project Overview: - 65MW triple extraction, condensing, steam turbine generator
- Boiler modifications for increased pressure and temperature
- 220' circulator hog fuel stacker/reclaimer
- Mill piping modifications to move steam demand to lower pressures
- Conversion of boiler fans from steam turbine drives to electric motors
- Piping work is estimated at 50-60,000 man-hours
- Approximately 20,000 lf of piping
- Estimated completion of April 2009
Special points of interest: - 65MW steam turbine generator
- 50-60,000 piping man-hours
- 20,000 lineal feet of pipe
