Our Clients

“We needed some help to specify several high value relief valves for our equipment that met the strict requirements of our end client, providing several rigorous and well written reports with detailed calculation to show the valve specification would meet the demanding process conditions without failure for this low risk high consequence application. Although we have over 200 years of experience within our own team we felt we needed a greater degree of process competence to really show due diligence and so we turned to Flex Process for their specialist help and they not only fulfilled all of our expectations but did so in a timely and efficient manner. They worked with us to obtain the best solution and followed on by providing a full documentation pack and assistance through the purchasing phase. A pleasure to work with, and we look forward to working closely with them in the future.”

“For over 5 years Flexible Process Consultants (FPC) has provided a variety of work for us, ranging from the recent dynamic simulation of the flare system, numerous relief studies on critical areas of the plant, to producing process design packages and supporting detailed engineering on multiple projects at the Refinery.

Whenever I have used FPC I am always confident that I will be receiving quality engineering deliverables, on time, that are also fairly priced. When the occasional “rush job” has been placed on their doorstep, FPC has done all they can do to get the job turned around quickly, demonstrating their flexibility.

Due to its size FPC is able to work with individual customer needs. They understand that our design process can be organic and they patiently offer their expertise during the all stages of design. I particularly like benefits of working with a smaller engineering design firm, in having direct access to the principal, Roger Rayner.”

“Roger Rayner and Flexible Process Engineering is very well known to IDEAS Project Engineering Ltd. IDEAS handles project design for international, household-name clients in the Oil & Gas, Chemical and Petro-Chemical industries and our relationship with Roger of Flexible Process has been fundamentally important in successfully delivering safety-critical, technically challenging, process design to these demanding clients. Roger is very capable, technically knowledgeable and always delivers, good, properly thought through, solutions to process requirements, problems or issues, in a timely and efficient manner.”

– Glenn Baker, IDEAS Project Engineering Ltd.

“I was tasked with supporting Flexible Process Consultants on the client side in doing a flare and relief study for an operating installation where it was necessary to understand the current capacity. The execution of the study proved to be challenging due to the level of detail required, lack of as-built information, and time constraints.

Roger quickly understood the work scope and was invaluable in helping define the key deliverables and milestones. In an operating company where everybody is very busy, the need for the external consultant to work with minimal support is key. Roger demonstrated this by working independently, learning the client systems in order to get the required data, and only requiring direction when information was not obviously available.

As the study progressed, Roger adapted efficiently to changing priorities and growing work scope through effective communication and resource management. He was always happy to help resolve any ad-hoc queries from the client, even when it did not relate directly to the flare study.

The quality of the tools and deliverables developed by Flexible Process Consultants far exceeded similar ones previously developed by other external contractors. They have already proved to be valuable to the client for project development and process trouble shooting.

Roger’s flexibility, ability to work with minimal scope definition and support, is what made Flexible Process Consultants ideal for this type of study. His integrity, friendliness, and willingness to always help, is what gives the personal touch.”

“We encountered a complex problem relating to pressure relief of a number of reactors used in the manufacture of exothermic thermoset resins. The reactor vent capacity was not adequate for a number of scenarios that had been identified and it was necessary to determine the reactor relief capacity for a significant number of products with differing formulations, catalyst systems and fill levels. Flexible Process were very helpful in understanding the issues and determining the capacity of the relief systems under the various conditions which has allowed us to progress with our risk assessment. Further work will be required and we would have no hesitation in utilising Flexible Process”
