Reference Case: Inspection Services for Refinery Converting - Greece

Hellenic Petroleum S.A., Greece’s largest oil processing company, accounting for three quarters of Greece’s total refinery capacity at its three plants, decided to convert its second largest site, called “Elefsis Refinery”, to the production of low-sulfur diesel. In order to achieve this goal, compliance was required with national, EU and international regulations and standards.

Due to our strong international presence and extensive experience in this field, TÜV Rheinland was the preferred choice for Hellenic Petroleum.

Upgrading the Elefsis Refinery was a mammoth task, requiring compliance with all current environmental regulations and the fulfilment of technical specifications with regard to both function and cost effectiveness. In order to furnish Hellenic Petroleum with the full benefit of our wide array of inspection services, we provided both on and off site support.

Our approach consisted of daily inspections and tests on site for everything from welding procedures to NDT and mechanical tests as well as hardness, ferrite and particular material identification (PMI) tests. In addition, we provided witnessing for plumb and levelling equipment, installations of rotating equipment and internal and refractory equipment, as well as providing acceptance tests.

With the production of new components for use in the conversion of the plant to low-sulfur diesel fuel, we provided inspection services at the site of production, travelling extensively between sites of manufacture, utilizing our experts across a range of engineering fields and countries. Our shop, field and notified body inspections and services ensured compliance of components before installation at Elefsis Refinery.

We also provided inspection services at Elefsis Refinery, covering the full upgrade of the plant and overseeing the installation of new units for the processing of low-sulfur diesel fuel.

Finally, we audited certificates of compliance for equipment and valves, ensuring that the technical documentation would enable achievement of CE marking for the piping and units utilized in the upgrade of the plant.
