Dead weight tonnage (DWT) refers to the total weight in metric tons that a vessel can safely carry, including cargo, fuel, water, provisions, and other necessary supplies on board, while still maintaining its navigational and operational capabilities. It is a crucial measurement used in the shipping industry to determine a vessel’s carrying capacity and efficiency.
DWT does not include the weight of the ship itself or any permanent fixtures like machinery or equipment. Instead, it represents the difference between the ship’s loaded and empty displacements. This measurement helps determine the financial viability of a voyage, as it directly affects the amount of cargo a vessel can transport, the fuel required, and subsequent voyage costs. Generally, cargo is loaded until the ship reaches its maximum DWT, optimizing transport efficiency without compromising the vessel’s safety or stability.
