Inherent Safer Design

Eliminate hazards at source — Substitute, Minimise, Moderate, Simplify — applied at concept and FEED stages.

Strategic context

Why inherent safer design matters

Inherent Safer Design is the most economically effective risk reduction available — but only if applied before the design freezes. Our team spans CCPS / IChemE / EPSC frameworks: project-level reviews at concept and FEED, targeted Substitute / Minimise / Moderate / Simplify workshops, Heikkilä ISI and INSET Toolkit quantitative scoring, technology selection for inherent hazard reduction, ISD-by-design integration with HAZOP, and process intensification reviews that convert batch hazards into continuous-flow safety. Hazard elimination at concept is 10–100× cheaper than control-layer retrofit later.

Inherent Safer Design
Engagement model

How we deliver

A phased, evidence-led delivery model — from discovery through close-out — built around your facility, regulatory context, and lifecycle stage.

Concept-Stage ISD Scoping
Establish ISD review timing against project stage-gates — concept, FEED, post-FID; identify design-freeze risks and capture the early ISD opportunities that disappear after P&IDs issue.
SMMS Workshop Facilitation
Substitute, Minimise, Moderate, Simplify per process node and chemical inventory; multidisciplinary team — process, operations, safety, reliability, R&D.
ISI / INSET / Dow F&EI Scoring
Quantitative hazard-reduction scoring of design alternatives using Heikkilä ISI, INSET Toolkit, Dow Fire & Explosion / Chemical Exposure Index.
Technology Selection & PI Review
Evaluate process intensification (microreactor, continuous-flow, structured reactor) as default ISD route; capex / opex / schedule / ISD-score trade-off matrix.
ISD Design Basis Issue
ISD design basis document handed to HAZOP / SIL / FEED-gate review; ISD credit captured in downstream LOPA reducing SIL allocation burden.
Outcomes & value

What this service delivers

  • Hazard elimination delivering 10–100× lifecycle cost savings vs control-layer retrofit
  • Inventory reduction collapsing consequence-zone footprints
  • SIL allocation burden reduced through ISD-driven hazard removal
  • Process intensification opening modular construction and faster startup
  • Audit-defensible ISD design basis surviving CCPS Vision 20/20 review
Why Arborion

Our differentiators

  • Concept / FEED-stage engagement model — not late-stage bolt-on
  • Quantitative ISI / INSET scoring — not opinion-based ISD ranking
  • Process intensification evaluation as a default ISD step
  • Integration with HAZOP / SIL workflow eliminating duplicate scrutiny
