What we do

Four focused practice areas

Controls & Automation

We help clients evaluate, improve, and troubleshoot control systems throughout their lifecycle, from design and implementation to startup, operation, and modification.

  • DeltaV DCS & PLC systems

  • Control strategies and Sequences

  • Modernization and migrations

  • Startup and commissioning

Functional Safety

We help clients develop, implement, verify, and maintain safety instrumented functions throughout the functional safety lifecycle.

  • SRS development and review

  • SIL verification and calculations

  • Validation and proof testing

  • Lifecycle management

Instrumentation Systems

We help clients select, evaluate, and improve measurement systems, including process instrumentation, analytical instrumentation, and critical process measurements.

  • Process instrumentation

  • Analytical instrumentation

  • Measurement-system performance

  • Critical process measurements

Forensic Engineering

We help clients understand failures, evaluate technical evidence, and develop defensible engineering conclusions.

  • Failure investigations

  • Incident reconstruction

  • Technical causation analysis

  • Expert Consulting & Litigation Support
