dotsHeritage & Timeline

A 50-Year Journey of Engineering Excellence

It all started with a bold idea and a handful of passionate engineers. Five decades later, we've grown into a trusted name in petrochemical engineering—thanks to the people, the partnerships and the projects that shaped our journey. This timeline isn't just about dates and milestones. It's a story of grit, innovation and the moments that made us who we are. Come take a walk through our history—and see how far we've come, together.
