Embedded engineering support
Placing an engineer or tech on site for months at a time, backed by senior subject-matter experts and HST Case, our plant knowledge system. A model few firms of our size can offer.
Industrial controls engineering
PLC and HMI design and programming, control system upgrades and migrations, integration with plant equipment, commissioning and startup support.
Power engineering
Power distribution design, arc-flash and short-circuit studies, protection and coordination, stamped drawings and engineer-of-record services.
Quality programs & regulated industry
NQA-1 program experience and nuclear design background. We bring documented rigor to plants that require it.
Licensure
HST’s principal engineers hold Professional Engineer licenses in Alabama, Florida, Georgia, Illinois, Iowa, Louisiana, Michigan, Mississippi, North Carolina, Ohio, Oregon, South Carolina, Tennessee, Virginia, and Washington, with Kentucky in process. All engineering work is performed under the responsible charge of a licensed principal. Additional state registrations obtained as projects require.
Plant knowledge systems
We deploy HST Case, a private AI troubleshooting assistant built on a plant’s own manuals, drawings, PLC exports, and fault history. It runs on dedicated hardware or in the plant’s own cloud tenant, never on a public service, and every answer cites the source document. Our engineers work with it on every engagement; plants that want it for their own teams can license it.
