RELEVANT PROJECT EXPERIENCE
INDUSTRIAL PROJECTS:
IMPERIUM RENEWABLES BIO-DIESEL FACILITY, ABERDEEN, WA.
The project purpose was to build a bio-diesel facility using petroleum process technologies to create a continuous process facility (not-batch). Essentially, soybean oil and methanol are injected into the system and the end product is ASME certified biofuel. This project was one of the most successful projects Mr. Stokes had ever worked on. Mr. Stokes performed as the lead electrical engineer and conducted his normal duties as Electrical Department Manager. One of the most innovative controls designs of its time, the control systems utilized Foundation Field Bus from all devices in the field to a Yokogawa CS3000 DCS. The unique part of this project was the use of ‘high powered trunk” communications from the DCS to locations outside of the Class 1 Division 1/2 areas and then utilizing the ‘low powered communication drops” (intrinsically safe) to the devices located in the classified areas. This reduced the cabling and wires to the field substantially. There currently are over 2500 devices (valves, motors and instrumentation) communicating over 178 Foundation Field Bus and Ethernet communications to the DCS.
SIMPSON TACOMA KRAFT PULP MILL COGEN FACILITY (NOW WESTROCK), TACOMA, WA.
The project purpose was to install a 60MW co-generation facility within the facility. There were several challenges ranging from limited space for the facility to adding a new electrical switch yard (by Tacoma Power). The project duration was to be 18 months which the engineering team and contractor worked hand in hand to make that milestone. The team came in two weeks late but considering that the asbestos remediation took an extra four weeks, the client willingly added to two weeks to the schedule. Mr. Stokes performed as the lead electrical engineer and conducted his normal duties as Electrical Department Manager. In addition to managing the electrical personnel, Mr. Stokes frequently managed civil and mechanic engineers an acted as a sub-project manage to the client’s project manager. The team worked on-site the entire 18+ months and were praised by the client for engaging with the contractor at all levels. Mr. Stokes also conducted meetings between the client and Tacoma Power. His role was one of assisting the client in understanding the wheeling fees and other regulatory issues when adding 60 MW to the electrical grid. Overall, this project was the most successful project Mr. Stokes has worked on.
SCHNITZER STEEL INDUSTRIAL WAST WATER FACILITY, OAKLAND, CA.
The project purpose was to meet new regulatory requirements for facility discharge to the San Francisco Bay during extreme flooding conditions. The facility had several violations during major rain events and was being influence by the EPA to update their facility to the new standards. The facility needed updating, not only a process standpoint, but also much of the outdated equipment that was originally planned to be reused. Mr. Stokes evaluated the electrical, instrumentation and control and concluded that much of the electrical and instrumentation had to be updated. Additionally, since the facility already had a SCADA/PLC system for another process area of the facility Mr. Stokes made sure the new systems was fully compatible and an extension with the existing Siemens S7 PLC control and SCADA HMI system. It was recommended to hire the previous SCADA/PLC systems integrator to expand the control system which turned out to be to the client’s advantage. The facility now meets regulatory requirements, and the client is satisfied with the project engineering and construction.
SAMSUNG Austin Semiconductor WASTEWATER TREATMENT FACILITY, AUSTIN, TX.
The project purpose was to meet new regulatory requirements for facility discharge to city sewer. With the unusually harsh extremes in pH and heavy metals, this project was one of the most challenging with regards to applying instrumentation correctly. The discharge from the facility typically had chemical extremes outside the range of the available instrumentation on the market. Reducing the extreme samples by ratio mixing with other fluids brought the discharge to a readable values. This project also included detailed engineered control panel designs utilizing Allen Bradley Control Logix PLCs to update the entire discharge portion of the facility. Mr. Stokes worked closely with the project manager and process engineer to come up with instrumentation and innovative ideas to properly test the discharge wastewater. The project was very successful
