Biography

Greg Siemon is a chemical/process engineer with over 18 years experience in the downstream petroleum industry. With extensive experience in operations, project, supply chain and business/project economics, I have a strong track record of finding simple and low cost solutions to complex and cross business problems that have delivered sustained long term benefits. I have been leading teams for many years and have consistently received praise for the way that I mentor/develop my people and deliver results.

He is currently working to complete a PhD studying Enterprise-wide Optimisation (EWO) in Steelmaking at The University of Queensland.

“Enterprise-Wide Optimization (EWO) is a new emerging area that lies at the interface of chemical engineering and operations research, and has become a major goal in the process industries due to the increasing pressures for remaining competitive in the global marketplace. EWO involves optimizing the operations of R&D, supply, manufacturing and distribution of a company to reduce costs and inventories. A major focus in EWO is the optimal operation of manufacturing facilities, which often requires the use of nonlinear process models. Major operational items include planning, scheduling, real-time optimization and inventory control. One of the key features in EWO is integration of the information and decision-making among the various functions that comprise the supply chain of the company.” (https://www.cmu.edu/ices/research/ewo/index.html)

While studying at UQ, he has been fortunate to be a member of the teaching team in a number of undergraduate and masters level courses including Unit Operations, Process Modelling & Dynamics, Integrated Safety Design and Management, Advanced Process and System Modelling and Whole of Process Optimisation and Control.

Refinery Scheduling Lead

Shell

Jun 2008 – Jan 2010 Geelong Refinery, Geelong, Australia

Accountabilities

  • Ensuring that the day to day refinery schedule allowed the right products to be made at the right time at the right quality using the monthly plan & daily economic guidance as an anchor. This was the main activity in the Shell S&OP Plan execution activity.
  • Minimised quality giveaway (making the product better than it needed to be) on key products
  • Scheduling Focal Point for Tank Maintenance Activities across the region to ensure that local decisions did not impact on supply chain feasibility.
  • Coordinating and ensuring consistency of schedules with the other two refinery schedulers and the distribution team based in Melbourne.

Achievements

  • Managed the Petrol and Avgas import and pipeline logistics during a 90 day shutdown of the Refinery in 2009. All products were imported during this time and it was the first time the refinery had been completely shutdown for that long. There were zero stockouts, zero product quality incidents and ship demurrage was significantly below plan. I successfully managed supply situation around a 10 day planned Geelong-Melbourne pipeline outage (pipeline normally transferred 10 million litres of product each day) with no impact on our customers.
  • Managed refinery schedules, pipeline and ship logistics for 4 grades of Diesel (specifications changed monthly), 3 grades of Petrol (specifications changed monthly), Jet Fuel, Avgas, 3 grades of Bitumen and 4 grades of Solvents with over 50 different feedstocks that changed every 3-4 days.
  • While acting Economics and Scheduling Manager, lead the team through an two week unplanned plant shutdown that occurred three days before Christmas. Continuously kept the wider business updated with stock projections while continuing to supply a much product as possible from the other production units that continued to operate at reduced capacity.

The implemented project cost was slightly over $1 million. Several previous studies had concluded the only viable options would cost over $100 million.
  • Lead development team that allowed refinery to reduce the amount of Benzene in Avgas by 90%. This was done using a new formulation with less than $50 000 in plant modifications. The first batch of Avgas was produced on spec and on schedule and significantly reduced aircraft refueler’s Benzene exposure.
  • Lead team implementing Product Quality Giveaway system improvements. Substantial reduction in giveaway (making the product better than it needed to be) in 2007 on gasoline grades over previous years.
