Field instrumentation for a refinery upgrade
Instrument detailing, hook-ups and loop drawings for a brownfield unit, issued ahead of the construction window.
Instrumentation and control engineering that holds up at site acceptance.
AK Instrumentation and Control Systems designs, builds and commissions instrumentation, PLC, DCS and SCADA systems for process plants, from site survey through FAT, SAT and post-SAT support.
Field signal: 4 to 20 mALoop check, tag by tag
Engineers who have stood in the control room at start-up
We are a team of instrumentation and control engineers who follow a project end to end: surveying the site, drafting the loop diagrams, building the panels, and being on site when the loops are checked. That keeps documents, hardware and software consistent with each other.
We support all major automation platforms and work to IEC, ISA and client standards.

Project stories
Replace these samples with your own completed projects.
Legacy PLC replacement
Existing drawings and logic recreated, then migrated to a current platform with a phased cutover.
SIL verification for an ESD system
SIL calculations and safety requirements specification prepared for an EPC contractor.
How we work
On time
Clear schedules, regular progress reports and no surprises close to deadline.
Checked before it leaves
Every drawing and logic package is reviewed against the specification before issue.
Cost-conscious
Right-sized solutions and a lean team, so you pay for engineering rather than overhead.
Knowledge hub
