Inspection of oil installations

Industrialised countries accumulate oil reserves to be able to adjust supply in real time to fluctuating consumer demand. The storage of hydrocarbons also makes it possible to guard against international crises, or to preserve crude oil while waiting for its refining. Oil storage presents two major risks: fires and soil and groundwater pollution. Avoiding this pollution is a major challenge, for which Eurocontrol is involved in checking the condition of tanks and their degree of corrosion.

What is

Inspection of oil installations?

Storage facilities for petroleum liquids, both storage facilities and facilities for consumption at the facility itself and for supply to vehicles, must undergo the necessary regulatory inspections to check their watertightness, mechanical strength and safety devices.

Early detection of possible wear of the material prevents any leakage of the contents of the installation that could pose a fire or explosion hazard and the emission of discharges harmful to the environment.


Royal Decree 1562/1998, of 17 July, modifies the Complementary Technical Instruction to the Regulation of Petroleum Installations MI-IP02 "Petroleum liquid storage facilities" and regulates the conditions for its inspections.

For their part, storage facilities for consumption at the facility itself and for supply to vehicles are governed by Royal Decree 1523/1999, of 1 October, which modifies the Regulation of Petroleum Installations, approved by Royal Decree 2085/1994 of 20 October, and the ITC MI-IP03 and MI-IP04 "Installations for supply to vehicles".


Eurocontrol carries out inspections and periodic reviews, as well as the certification of initial and periodic tightness tests in these three types of installations and has the highest possible accreditation in this field.

acoustic emissions
Acoustic emission NDT

Acoustic emission is a phenomenon of energy release in the form of transient elastic waves within a material under stress. Detection and analysis of the signals provide information about anomalies in the stress field, e.g. related to the presence of defects. The detection is performed by a piezoelectric sensor attached to the structure.
