Calibration Storage Tanks

  Shell Settlement Survey in-service Tanks The shell settlement survey will be carried out on periodic basis and depends on the assessment of soil and settlement predictions. The relevant standard is API 653 will be the document to identify an evaluate any tank bottom settlements.

  Bottom Settlement The survey will be carried out for any significant depressions or bulges in the floor of the tank shell based on the recommended standard API 653 B3.3 to address the form of settlement.

  Floor Edge Settlement

  Edge settlement occurs when the sharp edges settles around the periphery thus resulting in deformation of bottom plate near shell to bottom corner junction (or) depth of depressed area of bottom plate. The floor edge settlement will be carried as per API 653 B

  Shell Roundness Survey The survey of tank will be performed according to ISO 7507.The objective is to obtain two heights of each strake. The internal radii at each measurement at 310 mm above the base of tank shell to generate the roundness report.
