GPA’s risk and compliance team delivers rigorous risk identification, practical assessment, and implementation of tangible mitigation measures that are appropriate to the risk and our client’s operations.

GPA’s process engineering team delivers single and multi-discipline engineering projects for Greenfields and Brownfields plants across various industries including: oil and gas, mining, mineral processing, water and chemical, including the developing hydrogen and future fuels industries. Our strength in process design and optimisation is due to our strong affiliation with operations and production, and our ability to work with client operation and maintenance teams, to define problems and identify solutions. We perform facility process modelling to provide: sizing, debottlenecking, optimisation, heat recovery and efficiency improvements for gas, liquids and multiphase systems.
