Summary

The Chemical and Downstream Oil Industries Forum (CDOIF) has recently published guidance to help duty holders who may be considering the use of leak detection systems to provide mitigation against the loss of product from an Above-ground Storage Tank (AST).

Hazardous substances which are stored in ASTs could have the potential to pollute the environment or harm people if the primary containment measure in which they are stored (i.e. the tank) fails. Leak detection is one method by which hydrocarbons can be detected should primary containment fail. Early indication of the failure may ensure that mitigation measures to prevent escalation of the scenario can be deployed quickly.

There are different leak detection methodologies available, which each have their own strengths and weaknesses. Methodologies considered in terms of their benefits, limitations and indicative costs are described in the guideline..
