Motiva Selects AspenTech Operator Training Solution for Major Refinery Project

AspenTech's Virtual Plant Simulator enables refinery to provide a comprehensive training program to support the safe and efficient introduction of a new plant control system

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Feb. 18, 2004-- Aspen Technology, Inc. (Nasdaq: AZPN) today announced that Motiva, a joint venture between Shell Oil Company and Saudi Refining Inc., has selected AspenTech to supply operator training simulators for its Norco refinery in Louisiana. The simulators will help to ensure the safe and efficient operation of the refinery during the transition to a new distributed control system (DCS), which is being installed in all of the plant's main process units.

The Norco refinery has a capacity of 240,000 barrels per day, and produces a range of oil products including gasoline, jet fuel and diesel fuels. The refinery is undergoing a major re-instrumentation project, installing an Emerson DeltaV(TM) DCS system in seven key process units including the catalytic reformers, coker, hydrocrackers, hydrogen plant and hydrotreaters. As each unit changes to the new control system, AspenTech's simulators will be used to provide rigorous training in advance of the cutover.

"The operator training simulators are an integral part of the re-instrumentation project, and will facilitate the successful transition to the new control system," said Mike Wilson, Re-Instrumentation Project Manager of Motiva. "AspenTech's model-based simulators will enable the refinery to realize value not only during the initial training phase, but also continued training including situational training, and by supporting operational improvements once the new systems are in place."

The training systems are based on AspenTech's proven Virtual Plant Simulator (VPS) solution architecture, with HYSYS(R) modeling software used to create dynamic simulation models of the plants incorporating their detailed process characteristics. The use of HYSYS will enable the VPS solution to deliver greater benefits than systems based on dedicated operator training applications. HYSYS is widely used as a modeling platform in the petroleum industry and, in addition to training, the HYSYS models can be used for a range of other functions during the lifecycle of the refinery, such as process troubleshooting and operations analysis. Since many process engineers are already familiar with HYSYS, the models can also be easily maintained and updated.

Motiva selected AspenTech after a detailed competitive evaluation that highlighted the better quality and accuracy of AspenTech's technology, its experience in delivering similar VPS systems, and the greater long-term value of its solutions compared to the operator training systems previously used at the refinery.

"This new project highlights the value that AspenTech's Virtual Plant Simulators can deliver to the refining industry," said David McQuillin, President and CEO of AspenTech. "By combining the HYSYS modeling software with our proven solution architecture for operator training, we can deliver a comprehensive solution that can deliver value throughout the lifecycle of the plant."
