Aspen Technology, Inc. announced that SBM Offshore has signed a multi-year license agreement to expand its use of AspenTech's engineering solutions. The new agreement provides access to applications including Aspen HYSYS and the Aspen HYSYS Upstream option which are key components of the integrated aspenONE for Oil & Gas solutions. SBM will use the applications to support the design and optimization of new and existing oil and gas production facilities. Earlier agreements were signed by several SBM Offshore Group companies - GustoMSC, SBM-Imodco and Single Buoy Moorings - in which they adopted Aspen HYSYS as their standard simulation platform. The new agreement enables SBM to expand its usage of the tools to support a range of other applications including Aspen HYSYS dynamic simulations and the design of heat transfer equipment. The Aspen HYSYS process simulation environment used by SBM combines a user-friendly architecture with industry-leading simulation technology. The Aspen HYSYS Upstream option extends these capabilities by providing industry standard methods and techniques for handling petroleum fluids.
