The risk of flammable dangerous liquids stored on the industrial premises escaping
into the environment in the event of major industrial accidents must be minimized.
Such a risk reduction result can be achieved by the use of safety barriers, such as
a remediation bund area, which can retain, collect and store the released material.
The careful determination of design parameters of this installation is of great importance.
Therefore, this study–based on the analyses of applicability of existing guidelines
(SPCC and HSNOCOP 47)—will propose a new sizing calculation methodology to design
optimal and efficient remediation bund parameters, including the remediation bund
wall height and distance between the remediation bund and the storage tank walls.
The design parameters are defined by applying Toricelli’s theorem and their practical
compliance is tested using consequence analysis simulation software ALOHA 5.4.7 covering
three possible major accident scenarios. As a result of the newly proposed methodology,
the risk of overflow through the remediation bund wall can be excluded and higher
effectiveness of the application of firefighting and technical rescue intervention
activities can be ensured. The results of present research ultimately serve to prevent
major industrial accidents and eliminate their possible harmful environmental impact.
