单词 | deadweight |
释义 | deadweightdead weightor dead·weight (dĕd′wāt′)deadweight(ˈdɛdˌweɪt)DeadweightDeadweightthe gross weight of a ship’s cargo. The deadweight, in causing a ship to settle to its summer load line in seawater, is an indicator of a freighter’s dimensions and its basic operational characteristic. Quantitatively, the deadweight is equal to the difference between the water displacement and the ship’s own weight, including its machinery and equipment ready for operation (along with pipelines filled with fuel, water in the boilers cooling the pipelines, etc.). The principal part of the deadweight of a freighter is the weight of the cargo; on a passenger ship the weight of the cargo (passengers and baggage) amounts to the lesser part of the deadweight, whereas its greater part is made up by the supplies expended by the ship (fuel and water). |
