【摘要】：对世界商船队船型、船龄和吨级构成特征进行统计分析,确定了散货船、油/化学品船、集装箱船、杂货船、液化气船和滚装(客)船6种主要类型运输船舶为研究对象.根据各主要类型运输船舶船龄和吨级的数量占比,基于Clarksons船舶数据库进行随机抽样,确定了主机标定功率、副机标定功率和船舶设计航速与船舶总吨之间的拟合关系.结果表明,选用四冲程柴油机、二冲程柴油机和蒸汽轮机作为主机的船舶数量占比分别为27.6%、72.0%和0.4%;各类型船舶配置的主机平均数量为1.01~1.82台,副机平均数量为2.66~3.52台,副机与主机标定功率之比的平均值为0.19~0.35;船舶动力参数与船舶总吨之间的对应关系可采用幂函数或线性函数表达;除集装箱船外,近30年来,船舶动力参数与船舶总吨之间的拟合关系未发生明显变化.
[Abstract]:Based on the statistical analysis of the ship types, age and tonnage composition of the world merchant fleet, six main types of transport vessels, bulk carrier, oil / chemical ship, container ship, general cargo ship, liquefied gas ship and ro / ro (passenger) ship, are selected as the research objects.Based on the random sampling based on the Clarksons ship database, the relationship between the calibration power of the main engine, the calibration power of the auxiliary plane and the ship design speed and the total tonnage of the ship is determined according to the proportion of ship age and tonnage of the main types of ships.The results show that the number of ships using four-stroke diesel engine, two-stroke diesel engine and steam turbine as main engine is 27.62.0% and 0.45.The average number of main engines and auxiliary engines for each type of ship configuration is 1.01 ~ 1.82, and the average number of auxiliary engines is 2.66 ~ 3.52, respectively.The average value of the ratio of calibrated power between auxiliary and main engine is 0.19 / 0.35. The corresponding relation between ship's dynamic parameters and ship's total tonnage can be expressed by power function or linear function, except for container ship, in the past 30 years, the relation between ship's dynamic parameters and ship's total tonnage can be expressed by power function or linear function.The fitting relationship between ship dynamic parameters and total ship tonnage has not changed significantly.
