Delivering Value by Dynamic Simulation
Director Profile

Director / Chief Engineer - Stuart Williamson

Profile Summary:

An accomplished technical consultant with extensive experience (20 years) & highly successful career in all aspects dynamic simulation (using HYSYS / UniSim and OTISS) relating to engineering studies for process design, process control and operation, rotating equipment performance and control (for both oil & gas and petrochemical processes). A clear thinking team player committed to running professional well-organised projects with both technical and project management skills. Experience summary also includes leading / managing Operator Training Simulator (OTS) projects, and writing OTS bid specification documents (during FEED and EPC phase projects). Experience includes dynamic simulation software development for tactical technology developments, project technical support, and software performance improvements.

Key Technical Skills:

Dynamic Modelling and Simulation: Extensive experience (20 years) in dynamic modelling (HYSYS / UniSim / OTISS) and analysis of processes and their associated control systems, mainly focussing on the process industries, including process design and control, machinery and control systems (for oil & gas, chemicals, LNG, GTL, and refinery related projects). Specialist areas include oil & gas installations, LNG plants, Ethylene plants, and GTL plant modelling.

Process Design & Process Control: Good practical knowledge of process and control systems design. Experience in engineering design on FEED studies and EPC phase projects. Specialist interest in conceptual process design, control system design, operability and controllability, and rotating equipment controls.

Technical Management: Experienced in project management, technical management, and resource management (leading and motivating teams of simulation consultants).

Operator Training Systems: Technical manager and lead on numerous OTS projects while working for OTS vendor / EPC contractor. Production of project OTS specification documents for vendor bids, and experience as project management consultant (PMC) acting for clients on OTS projects. Experinced user of UniSim Operations software.

Simulation & Design tools: Experienced user in HYSYS (and UniSim) and OTISS for model development, dynamic simulation, and operator training. Working knowledge of PROII, AspenPlus, and DynSim. Practical knowledge of VB in EXCEL for the creation of off-line simulation tools such as trending tools, steady state reporting tools, data management / reporting tools.

Software Development & Maintenance: Excellent practical knowledge in the field of software development and maintenance. Developed cross project complex technical solutions such as reactor systems and dephlegmator models. Responsible for engineering software releases (both internal and external) and project technical support for a UK based simulation consultancy. Development of engineering blocks / algorithms for general release and project requirement, bug fixing, debugging and software performance enhancements. Experience of custom block creation (dynamic extensibility) within HYSYS / UniSim environment.
