Engineering Discipline
EC&I & Functional Safety
Electrical, control & instrumentation and functional safety — from requirements to validation.
Our electrical, control & instrumentation (EC&I) and functional safety engineers define how a plant is powered, controlled and protected — from power distribution and control philosophy to instrumented protective functions designed and assured to IEC 61508/61511.
What we deliver
Electrical load lists, single-line diagrams & distribution
Control & instrumentation philosophy & architecture
Functional safety: SIL determination & verification (IEC 61511)
Cause & effect, alarm rationalisation
Instrument datasheets & I/O schedules
FAT/SAT and validation support
Across every project phase
How ec&i & functional safety contributes at each stage of the lifecycle — and connects to the disciplines and delivery functions around it.
FEED
Single-line diagrams, control philosophy and architecture, instrument and I/O schedules, plus hazard and risk assessment inputs. Where the design is sufficiently defined, LOPA supports initial SIL determination before the safety requirements specification is set.
Detailed Design
Issued-for-construction EC&I packages, cause & effect, safety requirements specification, SIL verification and software requirements; earlier LOPA and SIL decisions are reviewed when the design changes.
Construction
Installation support, loop definition, EC&I TQs and inspection.
Commissioning
FAT/SAT, loop checks, functional-safety validation and proof testing.
Operations & Maintenance
Proof-test regimes, obsolescence management and control-system upgrades.
Where this capability is applied
Functional safety is decisive in major-hazard (COMAH) chemicals and waste-to-energy, while power and process plants demand robust control and electrical integration.
Single discipline or integrated scope
Provided as specialist functional-safety or EC&I support, or embedded within an integrated multidiscipline scope.
