Inspectahire was contracted by Occidental Petroleum Qatar to carry out in-service tank inspection to comply with current EEMUA 159 Guidelines on their final settling tanks on Halul Island in Qatar.
An in-service inspection was carried out on the above tank incorporating all of the tank features including drainage, foundations, shell, roof, wind girder, tank floor, welds, nozzles and manways, flow lines, fire sprinkler system and all structures. A team of rope access technicians with the appropriate NDT discipline qualifications were utilised to gather information and inspect areas where access was difficult. Meanwhile, a further team operated an Ultrasonic Crawler remotely from the ground gathering data on the tank shell and roof. All works were overseen by a qualified tank assessor, who collated the information and carried out the required calculations so as to inform on the tank condition for further operations.
The two main types of atmospheric storage tanks encountered are Floating Roof Tank and Fixed Roof Tank. Each type of tank requires a range of inspection techniques, for example: Tank Inspection Techniques
A qualified tank inspection report was produced for both tanks and this completed Occidentals compliance requirement under the EEMUA 159 standards for inspection of storage tanks.
