What We Deliver
Controls Engineering Capabilities
Control Narratives & Functional Specs
Detailed written descriptions of every control loop, sequence, and interlock — covering normal operation, startup, shutdown, and upset conditions. Written to API and ISA standards.
Cause & Effect Matrices
Complete C&E matrices mapping every process input to its required output — covering alarms, shutdowns, permissives, and interlocks. Structured for review, approval, and direct use by programmers.
PLC / DCS Logic Design
I/O architecture, tag naming conventions, state-based control logic, and sequence design — platform-agnostic documentation ready for implementation on Allen-Bradley, Siemens, Modicon, or Emerson DeltaV.
Safety Interlock & Permissive Logic
Documentation of all safety interlocks, emergency shutdown logic, and permissive conditions — structured for HAZOP review and SIS implementation, covering process and equipment protection.
FAT, SAT & Commissioning Support
Factory and site acceptance test procedures, loop check coordination, sequence verification, and first-start support — delivered on-site by an experienced senior controls engineer.
Packaged Equipment DCS Integration
Integration of vendor-supplied package units into plant-level PLC or DCS systems — including signal interface documentation, I/O mapping, alarm strategy, and loop verification.
