A well-conducted Draft Survey of a large vessel should achieve accuracy to with in 0.5%.

The final report of draft survey should incorporate every aspect and difficulty, which has been encountered in order to convey all aspects of the survey.
Draft Survey Certificates of AIM Control Inspection Group according to UN, ECE International Code.
Draft Survey is an international commercial custom that traded quantities of bulk cargo such as iron ore, coal, steel scrap, grain and some specific quantities of liquid cargoes are determined by draft survey.
During a draft survey, cargo quantities are calculated based on the change of ship's drafts between different stages in the loading or discharging process by using the scales and hydrostatic property tables on board the ship. This convenient method is universally adopted as the most efficient and reliable way of measuring the cargo quantity where accurate product properties such as density and stowage factor are not reliable.
Cargo survey conducts draft surveys on a variety of different ship types and cargoes. We use internationally recognized methods and modern equipment for measuring the necessary variables for an accurate outcome.
AIM Surveyors conduct initial & final draft survey in association with Master of the vessel to ascertain the quantity loaded in the vessel and issue the weighment certificate / Draft Survey Report. The Draft Survey has to be carried out by qualified and competent / experienced surveyor. The Draft Survey report shall consist of following:
·Density of sea water at load port
·Stability tables (hydro-static) of the vessel
·Sounding of all tanks available on the vessel
·Details / particulars affecting the Draft Survey results
·Facts & figures of consumables / deductions on the vessel at Initial & Final Survey
·Trim to be applied for ascertaining quantity of Ballast and fresh water.
