Tank Integrity


Safeguarding storage tanks with respect to Irish COMAH regulations. 


In order to safeguard the integrity of vertical storage tanks (VSTs) which fall under COMAH regulations, varying levels of routine inspection (and associated maintenance) dependant on a VSTs service, and history is recommended.

Inspections should be broad, covering all aspects critical to a tanks integrity. By API and EEMUA it is advised that inspections should  include  weekly checks which may be carried out by the tank operators own site personnel, and up full top to bottom internal and external inspections which should be performed by an authorised API or EEMUA tank inspector.

By following an approved inspection regime, any storage tank can be assured to be in its best possible condition and fit for purpose. 

In addition to regular inspections some tank farm operators wish to go beyond the  API and EEMUA standards to tailor an inspection regime for their specific cases, e.g., a tank with a known deformation which is acceptable but requires continued monitoring, or a change of product which may or may not cause an increase in corrosion rates.

To help with the former we work in collaboration with Murphy Surveys we use high definition laser scans to accurately measure and compare all aspects of a tanks dimensions to API 653 or EEMUA 159.

This data can also be use for FEA purposes to access particular areas of concern and if necessary model a suitable repair solution. More information can be found here.
