Casne Engineering provided the electrical and control systems design for automating the existing railroad fueling facility for BNSF in Cicero, Illinois. An Allen-Bradley PLC-5 controls the functions of the diesel fuel oil tank farm, pump house, and fueling platform systems. Remote I/O panels interfaced to the PLC via AB’s ControlNet communication network. A PC-based HMI operator interface allows the site personnel to control, monitor, and trend the entire system. An emergency generator provides back-up power for all processes.

Casne Engineering provided electrical and controls engineering design services for the demolition and installation of four Dye Penetrant Tankline tanks. The control systems were designed, tested, and commissioned by Casne for turnkey operation. The tankline consists of 104-feet long Alkaline Etch, Alkaline Rinse, Desmut Dip, Desmut Rinse, Dye Penetrant, Spray Rinse, Powder Developer, and Dryer tanks. Casne provided construction assistance and process programming with start-up services to meet a stringent two-month deadline for construction implementation and turnkey delivery of the tankline. Casne provided coordination of the construction to minimize tank down time and maintain current production levels.

In order to maximize the efficiency of four hydro generators and still meet Federal Requirements for minimum flow over Snoqualmie Falls, Casne Engineering provided programming modifications to existing Harris RTU’s. A priority-based load trimming scheme was developed that controls load based on the level of the river over the falls. During the day, the flow over the falls is optimized for aesthetics and during the evening the spill over the falls is kept to a minimum in favor of power production.

This project consisted of the automation of an existing waste-rinse water treatment plant at the Boeing Renton Facility in Renton, Washington. The wastewater treatment plant is used to remove chemicals, solvents, and particulates collected from wash-down processes at two separate paint hangars at the site. The system included two 10,000-gallon treatment/storage tanks, two 25,000-gallon treatment/storage tanks, chemical addition systems, a sand filter, and an air-stripping tower. The project was developed to fully automate the batch processing procedure and to improve the system flow capacity. This work was accomplished while maintaining facility operations with a minimum of down time.
