1.1 This part of ISO 9091 describes a stereo-photogrammetric procedure for the internal measurement of spherical tanks in liquefied-gas carriers.
1.2 In addition to the actual process of measurement, this part of ISO 9091 also sets out the calculation procedures for compiling the calibration tables.
Internal dimensions of spherical tanks in liquefied-gas carriers are determined by taking overlapping stereo photos under isothermal conditions. Coordinates are computed. Additional trim, list and tank shell expansion corrections may be made.
