Nuffield Radiographic Inspection have been carrying out oil storage tank surveys for over ten years and have built up a wealth of experience. Tank surveys are carried out using ‘A’ scan presentation and digital ultrasonic equipment on the tank shell roof, and floor. Tank shells are accessed by operators using rope access equipment, however scaffold towers, hydraulic platforms or cradles may be used as appropriate. These methods offer the advantage over other remote systems in that it enables our operators to carry out a thorough visual inspection of the welds and plates as the survey progresses. The survey system is highly flexible and can be adapted to suit the clients requirements with regard to how detailed the survey should be.



During inspection of the tank floor plates it is our normal procedure to carry out vacuum box testing of all accessible lap welds. Our operators are trained in the use of Breathing Apparatus and are familiar with the requirements of current legislation.
