Our Mission

At PFS our mission is to serve as a one-stop solution for tower and vessel maintenance with the highest degree of safety, quality and execution. We strive to achieve the maximum level in client satisfaction through our commitment to having zero incidents and zero re-work. Our experienced team members exemplify professionalism through their timely and effective completion of tower and vessel turnaround projects.

Our Team

At Petrochem Field Services, Inc., our management and supervisory teams average over 20 years of experience in tower and vessel maintenance, fabrication, modification and internal installations. Our successful execution of projects for companies such as ExxonMobil, Shell Oil, ConocoPhillips, Valero, Motiva Enterprises and S&B Engineering, along with an OSHA incidence rate well below the industry average, have resulted in continuing repeat business from these and others, both in the United States and internationally. All of this would be impossible without our highly skilled team; it is the people that make PFS what it is.
