Our Draft Survey Service: Precision in Maritime Cargo Measurement

At the heart of global trade, the maritime industry relies on accurate cargo measurement to ensure that goods are loaded and discharged safely and efficiently. Our Draft Survey Service is designed to meet this critical need, providing precise measurements that are essential for the safe transportation of goods by sea.

To conduct a draft survey, our highly trained and experienced surveyors follow a meticulous process that involves a series of steps. First, they measure the drafts of the vessel on both sides, taking into account the initial and final weight or displacement of the ship. This information forms the foundation of the survey.

Next, our surveyors measure the soundings of all ballast tanks and assess the density of the ballast water, a crucial factor in accurately determining the cargo’s weight. The density of the water in the port is also taken into consideration to ensure the utmost accuracy in the calculations.

To complete the data collection process, our surveyors acquire bunker figures from the chief engineer and gather all other available weight information, such as fuel, drinking water, and other materials. These comprehensive data sets are then used in our calculations.

One key aspect of a draft survey is the calculation of the mean of mean drafts, a crucial step that helps refine our measurements. By combining all the data gathered during the survey, we can determine the weight of cargo loaded or unloaded with a high degree of accuracy. This precision is made possible by applying Archimedes’ principle, which underpins the entire draft survey technique.

Our Draft Survey Service
Our draft survey service is a comprehensive and accurate way to determine the weight of cargo loaded or unloaded from a ship. We use the latest technology and methods to ensure that our results are reliable and accurate.
The draft survey process begins with measuring the initial and final weight/displacement of the ship. This is done by measuring the draft of the ship (the distance between the waterline and the bottom of the hull) at six standard points on the hull. We also measure the soundings of all ballast tanks and the density of the ballast water.
We then determine the water density in the port. This is important because the weight of a ship will vary depending on the density of the water it is floating in.
Once we have all of this information, we can calculate the mean of mean drafts. This is the average of the drafts measured at the six standard points.
Finally, we use Archimedes’ principle to calculate the weight of cargo loaded or unloaded. Archimedes’ principle states that the buoyant force on a submerged object is equal to the weight of the fluid displaced by the object.
Our draft survey service is used by a variety of clients, including ship owners, charterers, cargo surveyors, and insurance companies. We are committed to providing our clients with accurate and reliable results that they can rely on.
