SGS Performed Storage Tank Inspection at the Cartagena Refinery Expansion

Bogota, Colombia (PressExposure) August 20, 2009 -- The expansion of the Cartagena Refinery to a capacity of 140 thousand barrels day is a strategic project for Colombia. Another aim of the project is to improve the quality of the fuels to meet national and international environmental standards, and to optimize financial and operational indicators. It is estimated that the project will be completed by 2010.

SGS Colombia was responsible for the inspection of floating-roof and conical-roof tanks with sizes between 20,000 to 130,000 barrels and evaluated the tank bottoms and roofs, as well as tank shells.

For the inspection of tank bottoms and roofs, SGS inspectors used Ultrasonic Testing (UT) methods such as B Scan and C Scan in order to detect corrosion. B Scan provides a cross-sectional image of the material and detects material thinning which is caused by corrosion in the inside of tank walls. The C Scan is used as one of the last tools during the inspection process as it is more accurate than the B SCAN. The C Scan is able to make cross-sectional images and identify failures of items located underground.

For the assessment of the wall thickness of tank shells, SGS used an ultrasonic crawler, a tool designed to cost-effectively take ultrasound thickness measurements on above-ground ferro-magnetic structures, without the need for costly scaffolding or industrial rope access.

The inspection services required 12 qualified SGS inspectors in order to ensure precise performance of the inspection as well as correct identification and orientation of the imperfections and reporting of the findings. The SGS inspection services were carried out in accordance with applicable Health, Safety and Environment (HSE) requirements as well as to the API 653 Program.
