DNV's pages describe Safeti as software that models consequences and risk in one interface, calculating risk from user-provided leak frequencies, ignition, weather, population and vulnerability data. Standard outputs include individual risk contours, FN curves and potential loss of life; typical uses named include fire and explosion risk assessment, occupied buildings risk assessment and risk-based design. Add-ons extend explosion, mixture and solid-explosion modelling. The vendor states that more than 1,000 organizations use it.
Built from vendor sources checked ; AI-assisted drafting. Documentation review, not a hands-on test. How pages are made
Process safety engineers and consultants who must produce numerical risk results for major hazard sites, occupied buildings or facility layouts. Results depend on inputs the analyst supplies, and use calls for trained specialists. Links to business systems and mobile use are not described; hosted access is limited to the FAQ's pre-installed virtual machine. Some explosion outputs need an add-on, and CFD import needs version 9.1 or later.
Watch for: Results rest on user-supplied inputs and need specialist skills.

Safeti is quantitative risk analysis software from DNV. It is an engineering consequence and risk-modelling tool for process plants, not a QHSE management system with workflows, records or registers. This profile covers Safeti and the add-ons its pages list. Phast sold on its own, which has its own page and price, Safeti Offshore and DNV's other software are out of scope. Safeti QRA software with its Extended Explosions, Multi-Component and Solid Explosions add-ons; licence types, training and support as the pages describe them.

| Occupied buildings risk assessment | Depends on scope | A dedicated page describes TNO multi-energy and Baker-Strehlow-Tang explosion methods and API 752 and 753 guidance; it marks multiple building types, frequency contours and exceedance curves as needing the explosions add-on.

| Loss of containment effects modelling | Documented by vendor | The FAQ describes discharge, dispersion, flammable and toxic effects, fires, explosions and BLEVE, shared with Phast; multi-component two-phase releases need the Multi-Component extension.
