 Code of Uniform Standards and Procedures for the Performance of DRAUGHT SURVEYS of Coal Cargoes

  Under the auspices of the then UNECE Working Party on Coal, the above Code was elaborated by experts from major coal exporting and importing countries. The Code was completed in October 1991.
The Code was adopted by the UNECE Working Party on Coal at its session in October 1991 (ENERGY/WP.1/2, paragraph 42) and endorsed by the UNECE Committee on Energy at its annual session in November 1991 (ECE/ENERGY/18, paragraph 23 (e)). It was agreed that the maintainance and application of the Code was to be monitored by the former ECE Meeting of Experts on Coal Trade, Statistics and Transport, in cooperation with other interested international organizations.

For over a century draught surveys have been accepted as an accurate and convenient means of establishing the weight of bulk cargoes. They have been the basis for the preparation of bills of lading and assessing various charges and port fees. The basic principle upon which the draught survey methodology is based is over 2,200 years old tracing back to Archimedes' Law of Buoyancy. The application of this law of physics to ships was further refined by formulas developed by European naval architects in the nineteenth century. While this principle is the basis for the work of draught surveyors throughout the world, the procedures by which they are applied vary considerably from country to country and even from port to port. The purpose of this Code is to make these procedures reasonably uniform. It is further designed to provide a professional standard for the work of the draught surveyor.
