The latest version of EFFECTS

Version 12.2 of EFFECTS and RISKCURVES software tools offers a range of improvements with a summary as follows.

The launch of the Liquefied Gas Release model, combining the previously self-standing models: the Liquefied Gas Bottom Discharge model, the Liquefied Gas Spray Release model, and the Liquefied Gas Vapour Venting model. This new model's internal mechanism automatically selects the appropriate option based on the input provided, alleviating users from the burden of making this decision.

Incorporating the Liquefied Gas Spray Release model into the Liquefied Gas from Long Pipeline model to eliminate the need to link these two models to obtain inputs for the dispersion or pool evaporation model.

Dedicated 10-minute release models have been integrated into their corresponding outflow models (Gas Release, Liquid Release, and Liquefied Gas Release models), providing users with the option to select “vessel empty in specified time” release type in the respective models as an equivalent to the 10-minute models.

An additional (expert) input has been added to the dispersion model, enabling customisation of the wind speed reference height beyond the default 10m.

Enhancements in the calculation of wind velocity profiles, resulting in increased accuracy of dispersion model results.
