process control engineering consultant

Control Automation and Process Control are essential for both day-to-day plant operations as well as plant optimisation.  There are often low-cost automation and process control opportunities which can yield significant margin and plant performance gains through debottlenecking, efficiency improvements or a combination of the two. Modern distributed control systems (DCS) and programmable logic controllers (PLC) provide sites the ability to modify controls quickly and effectively and we aim to work with you to maximise these gains.

These improvements may also provide additional added value by mitigating the impact and likelihood of cascading upset or trip events thereby increasing production up-time and system reliability.

The identification of opportunities during project and operational phases, along with a justified benefit analysis; may result in investment in activities which result in real financial and operational returns. The earlier these opportunities can be identified, the more cost-effective they are in terms of overall financial return.

We have supported multiple major process-control equipment systems and can complement your existing staff for control improvements in day-to-day plant operations as well in front end engineering design (FEED) and commissioning and start-up of projects.

We are able to assist you through your project cycle, with the following services and abilities:
