A draft survey is a calculation of the weight of cargo loaded or unloaded to or from a ship from measurents of changes in its displacement. The technique is based on Archimedes' principle. The procedure is standardized by the United Nations Economic Commission for Europe for the measurement of coal cargoes.

A draft survey is a means of determining the weight of any materials being loaded into (or discharged from) a vessel. SGS's experienced and highly qualified professionals can conduct a draft survey on your behalf and produce an independent draft survey report.

Vessel draft (draft in the American spelling, draught in the British) is one of the principal dimensions of any waterborne vessel and is defined in technical terms as the distance between the ship's keel and the waterline of the vessel.

Final Draft Calculation ? Fore and Aft Mean (FAm) = (Fcd + Acd) / 2 = (10.796 + 11.196) / 2 = 21.992 /2 = 10.996 M. ? Mean of Mean Draft (MM) = (Mcd + FAm / 2) = (10.965 + 10.996) /2 = 21.961 / 2 = 10.9805 M.

FORMULA : DIFFERENCE IN FORE & AFT DRAFT DIVIDED BY LBP MULTIPLIED BY DISTANCE FROM THE DEEPEST PERPENDICULAR TO THE MAST. THIS IS THE INCREASE IN AIR DRAFT ABOVE THAT DETERMINED BY SUBTRACTING THE DEEPEST DRAFT FROM THE HEIGHT OF THE MAST.

Vessel draft (draft in the American spelling, draught in the British) is one of the principal dimensions of any waterborne vessel and is defined in technical terms as the distance between the ship's keel and the waterline of the vessel.

Final Draft Calculation ? Mean of Mean Draft (MM) = (Mcd + FAm / 2) = (10.965 + 10.996) /2 = 21.961 / 2 = 10.9805 M. ? Quarter Mean (MMM) = (MM + Mcd) /2 = (10.9805 + 10.965) /2 = 21.9455 /2 = 10.97275 M.

To minimise these errors we finalise the draft of the vessel by having mean of means draft. This is also called Quarter mean draft. Mean of means is considered to be the accurate draft of the vessel at the midship. This is the draft we need to enter in the trim and stability booklet.

Explanation: Draft is calculated as, the difference between the starting thickness of the workpiece and the final thickness of the workpiece.
