Storage tank Inspection and Fit to Use Certification:
Storage-tank inspections cover both in-service and out-of-service inspections of above- and below-ground, vertical and horizontal tanks. An indepth condition report on the entire tank floor, shell, roof, and structure is provided using a variety of techniques, including finite element analysis in
line with API 653 & 650 and other pertinent standards. At the tank construction stage, engineering and inspection. We can offer Design Review and Approval, Tank Settlement Survey, Inspection and Approval of Civil Work, Welder Qualification Test and Welding Procedure Qualification, Other Relevant NDT Test, Third Party Inspection and Certification of Pipelines, etc. during the construction stage.
