Aspen HYSYS was used for feed verification studies and to perform utility, hydraulic and safety calculations during detailed engineering phases in Istanbul and on-site at the West Qurna 1 project in Iraq.
Engineers used Aspen HYSYS to prepare process simulations, steady state performance calculations and heat and mass balances, while exporting outputs into PFD and P&ID deliverables, equipment lists, line lists, process and equipment datasheets and bases of design. The implementation supported equipment sizing workflows including vessel, pump, orifice, NPSH, heat exchanger, compressor, separator, instrument air, KO drum, TEG Gas Treatment Unit and MDEA Gas Sweetening Unit calculations.
Operationally Aspen HYSYS was integrated in the engineering toolchain alongside Thermoflow/GT Pro for complementary performance and utility calculations, and its outputs were used to review vendor engineering documents and inform material selection and specifications. The Process Simulation deployment covered Process Engineering and Chemical Engineering functions, and extended to Field Engineering during construction and commissioning activities where engineering representatives conducted equipment walkdowns and supported first start and performance testing.
Governance and workflow changes centered on structured deliverables and site coordination, with engineering teams producing redline and as built documentation and coordinating field changes with employer and vendor stakeholders. Workflows reflected standards alignment, engineers applied API and ASME technical requirements within Aspen HYSYS calculations and in preparation of formal process deliverables.
