    Abstract - (Show below) - (Hide below)

    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.

    Scope - (Show below) - (Hide below)

    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.
