Utility Modeling and Engineering Support Built for Refinery Operations
Most Refinery Utility Models Were Accurate Once
Refineries run on utility systems that are complex, interconnected, and constantly evolving. New units get tied in. Equipment gets modified. Operating conditions shift. And the model, if there is one, quietly falls behind. When a capital project comes up, or a system isn’t performing the way it should, that’s when teams find out how much they were relying on assumptions.
Hydrus Works helps refinery teams replace those assumptions with real data. We start with onsite measurement across your utility systems, build field-validated hydraulic models, and, through UMaaS, keep those models current and available any time your team needs an answer.

Three Moments That Bring Refineries to Hydrus Works
An Expansion Is Coming
You need to know if the existing utility system can handle the new load before you commit to the design. An expansion that runs into cooling capacity, compressed air, or steam distribution constraints nobody accounted for is expensive to fix after the fact. We measure the existing system and give you a validated answer before the design is committed.
The Model Is Old and Nobody Trusts It
Or there isn’t one. Either way, the engineering team is making decisions on incomplete information, and eventually that catches up. Whether it’s a project team request, a reliability issue, or a long-overdue update, we build models the team can actually rely on.
Questions Come Up Constantly
Can we take this exchanger offline? What happens to pressure if we add this new demand? What’s the impact of the upcoming turnaround on steam distribution? Having a validated model means your team gets answers instead of estimates, and those answers are there for the next question too.
Why Refineries Choose Hydrus Works
Field-Validated, Not Modeled from Drawings
We don’t build models from P&IDs alone. We go onsite, measure actual operating conditions, and build from real data. The result is a model your team can trust for real decisions.
UMaaS Keeps It Working Between Projects
A model that goes stale is a model that gets ignored. UMaaS keeps your utility models current as tie-ins are added, equipment changes, and operating conditions evolve, so the model is useful the next time a question comes up, not just the first time.
Vendor-Neutral
No equipment affiliations. Our recommendations are driven by refinery performance and reliability.
Refinery Experience
We’ve worked in refineries. We know what the systems look like, how they actually behave, and what matters to the teams that operate them.
