**3.5 Ship's displacement weight components**

The ship displacement weight component consists of the ship's dead weight (DWT) and the weight of the empty vessel (light weight). Dead weight is the carrying capacity of a ship including the weight of: cargo, fuel, lubricating oil, drinking water, foodstuffs, crew + passengers and the goods they carry. Meanwhile, the weight of an empty ship can be divided into three major parts, namely: 1) Structural weight, consisting of ship weight, superstructures, and deck houses. 2) Equipment weight, consisting of anchors, anchor chains, windlass, rigging, capstans, steering machines, winches, derrick booms, masts, vents, navigation tools, lifeboats, davits, and other. 3) The weight of the motor and its auxiliary installations consists of the main motor, auxiliary engine, boiler, pumps, compressors, separators, pressure vessels, coolers, intermediate shaft, propeller, propeller shaft, shaft bearing, reduction gear, and all equipment in the engine room. The complete component of ship displacement weight is shown in **Table 4** (composite vessel). **Table 5** shows the weight of the engine and electrical parts, the hull weight and the interior for the composite ship.
