Who are OTECSA Consulting?
OTECSA Consulting Ltd. is a process safety consultancy with offices in Glasgow, Aberdeen, Dundee and Cornwall. We provide engineering and technical safety expertise to clients in the process industries; specialising in HAZOP, HAZID, LOPA, DSEAR and Hazardous Area Classification. This includes chemicals, pharmaceuticals, distilled spirits, petrochemicals, energy from waste and manufacturing. With over a decade of experience we can bring new ideas to help you solve your engineering and safety challenges. This adds significant value and energy to your projects through our dynamic, accommodating and enthusiastic approach to engineering design, design assurance and risk assessments.
In addition to our Process Safety expertise, our background in Process Engineering and Project Engineering means we can assist clients through what can sometimes be the daunting prospect of outsourcing specialist technical, compliance and design assurance studies. We pride ourselves in a flexible, adaptable approach to our work, to fit with clients needs, and we constantly strive to build strong relationships with our diverse client base.
We were formed in 2018 by Owen Llanwarne after more than 10 years in chemical operations and projects, equipment manufacturing, process engineering design and process safety consulting. Over the years Owen has worked directly for operating companies, manufacturers, design consultancies and been trained in technical, management and agile scrum methods.
The vision is to build OTECSA into an approachable, networked consultancy, with key partnerships in related design disciplines and specialist areas so that we can provide flexible and innovative solutions to our clients complex problems. Get in touch with Owen directly here.
