HARLAN GRAF – Senior Consultant
Mr. Graf has a degree in Chemical Engineering from the University of Tulsa. His 33 year career with a major oil company has given him a vast diversity of experience in both the technical and operations/management arenas. He has specific experience as a design engineer, chief process engineer, operations superintendent, operations manager, project manager, tech services manager, and refinery site manager. With two international assignments, he has a better understanding of how cultural differences play a key role in refining management organizations. During his career, Mr. Graf was intimately involved in the implementation of the Central Control Room concept at four different locations. This involvement included initial project development, construction, operations, and maintenance organizational staffing, and final implementation and move-in. In addition, Mr. Graf has a vast working experience with refining safety, operations, optimization and trouble shooting. At one of his international assignments, he was involved with completing construction, operator staffing and training, and starting up a grass roots refinery. This was particularly challenging, since many of the processes and computer aids we take for granted didn’t exist at that location.
HARRY WILLIAMS – Consultant
Mr. Williams has more than 30 years of training experience, with 25 years in the petrochemical industries. He is experienced in every phase of training, including assessment, design, development, implementation, and evaluation. Mr. Williams has also managed multiple operator training material development projects. He recently designed the operator training materials for a new plant start up, assembled a writing team, and completed the project under budget, and within the required timeline. This was particularly demanding since much of the equipment and process documentation was yet-to-be developed.
STEVE MADDOX – Sales Director
Mr. Maddox has an extensive background in Alarm Management Software sales and has helped thousands of customers develop solutions to improve situation awareness through alarm management, HMI design, and control room design. Over the last two years, Steve has participated in solutions development for 39 pipeline companies due to the pipeline industry PHMSA regulations for Control Room Management.
