Since 1992, Onyx Engineering has built a reputation doing one thing: full-discipline refining and petrochemical engineering, delivered along the Gulf Coast. We have all the disciplines in-house to get your project scoped, designed, and built. Just one team that knows refining and petrochemical work because it’s the only work we do.
Onyx Engineering can manage your project from inception through completion, but we also provide support if work needs to be outsourced.
When every discipline sits in the same building, problems get caught before they become change orders. We’re able to respond quickly as your needs change, and nobody’s waiting on a subcontractor’s schedule to clear.
Process, Mechanical, Instrumentation & Electrical, Civil & Structural, Estimating & Scheduling: the technical disciplines behind every refining and petrochemical engineering project Onyx takes on, from concept to construction. All live under one roof at Onyx, supporting clear communication throughout projects.
Project Management keeps every discipline moving on the same schedule, toward the same deadline, from the first estimate to the last punch-list item.
Safety is built into how Onyx plans, designs, and executes every job, from the first drawing to the last day on site. We provide staff, standby, and rescue teams.
Onyx is local. That’s not a marketing line. It means our engineers have experience working in the same facilities they drive past every day. We serve refining and petrochemical operators across Corpus Christi and the wide Gulf Coast, with projects extending into North Texas and Oklahoma.
We don’t do government or municipal work. Refining and petrochemical is the whole business, which means engineers here have spent their careers in it, not split among industries that aren’t related to yours.
Onyx has built long-term relationships with clients who started as one-off projects. That happens for a specific reason: honesty about scope, timelines, and cost. When we say a number, it’s the number. When we say a schedule, it holds. That’s the reason clients come back for the next project instead of shopping around. We’re who you want to partner with when building a successful team.
If you’re a contract administrator verifying a vendor before signing, that track record is the point. Onyx has been doing this work since 1992, with the same commitment to in-house, full-discipline work, from maintenance to multi-million dollar capital projects.
If you want to build your career doing refining and petrochemical engineering with a team that keeps its work in-house, see what roles are open.
