Petroleum and liquid petroleum products - Calibration of spherical tanks - External electro-optical distance-ranging method
This document specifies a method for the calibration of spherical tanks with a radius greater than 1Â m by means of external measurements using an electro-optical distance-ranging instrument (EODR). It also specifies the subsequent calculation and the compilation of tank capacity tables.
This document applies to spherical tanks built above ground, that are non-insulated, single-shell and with a radial variation up to 1Â %. The method specified in this document can also apply to spherical tanks built above the deck when the carrying ship is in the dock.
This document does not apply to the calibration of spheroidal tanks.
