Trant has worked in the Petrochemical sector for over four decades, enjoying repeat business from major oil and chemical companies, both in upstream exploration and downstream refining and oil storage. We have continually invested in training and the development of our staff so that they are equipped to operate safely within the potentially volatile conditions found in this sector.

We are proud of the fact that we continue to work for many of the major oil, bio-fuel and chemical companies, including Exxon Mobil, BP, Shell UK, Valero and Perenco.

Our key multi-discipline services within the sector include civil, structural, architectural, mechanical and electrical engineering, involving:
