The latest software version v13.1

What’s new in EFFECTS v13.1

Two updates focused on more realistic hazard modelling. An enhanced battery hazard modelling and extended underground pipeline rupture capabilities.

Improved: Battery hazard modelling

The battery release model has been enhanced in two complementary ways: the range of reported components has been expanded, and new representative mixtures have been added to the chemical database to support dispersion modelling.

Li-ion battery storage thermal runaway improvements

PREVIOUSLY

Model reported individual toxic components only during a thermal runaway event.

NOW

Model reports toxic, flammable and inert components, giving a more complete release profile.

New battery mixtures in chemical database

A representative battery off-gas mixtures have been added to the chemical database. These mixtures can be used directly as the source term in neutral dispersion models, providing a more practical and physically consistent basis for downstream consequence modelling. The battery thermal runaway mixtures can also be used with the regular dispersion model if release temperature is known.

• Removes the need to manually construct a representative mixture from individual species.

• Directly linkable to dispersion modelling workflows.

• Consistent composition — unrealistic sensitivity to conservatism settings has been removed.

Improved: Buried gas long pipeline modelling

Crater formation modelling for underground pipeline ruptures was introduced in an earlier version for pressurised liquefied gases. In v13.1, this capability is extended to gas long pipeline model, covering a broader range of transmission scenarios.

• Relevant for natural gas transmission and gas pipe transport applications (e.g., hydrogen, LPG vapour, CO₂, ammonia, etc)

• Supports consequence modelling for pipeline operators and transmission infrastructure risk studies

• Relevant for land-use planning assessments near buried gas infrastructure

This enhancement supports pipeline operators, engineering consultants, and risk analysts working on buried pipeline consequence modelling and infrastructure risk assessments. For detailed information, see the model documentation and validation report available for all EFFECTS users in our download centre.

New: German language support

Work in your preferred language with expanded multilingual support. EFFECTS and RISKCURVES are now available in German in addition to English, Spanish, and Chinese. This enables German-speaking users to navigate and use the software more efficiently in their native language.
