【摘要】：對世界商船隊船型、船齡和噸級構(gòu)成特征進行統(tǒng)計分析,確定了散貨船、油/化學(xué)品船、集裝箱船、雜貨船、液化氣船和滾裝(客)船6種主要類型運輸船舶為研究對象.根據(jù)各主要類型運輸船舶船齡和噸級的數(shù)量占比,基于Clarksons船舶數(shù)據(jù)庫進行隨機抽樣,確定了主機標(biāo)定功率、副機標(biāo)定功率和船舶設(shè)計航速與船舶總噸之間的擬合關(guān)系.結(jié)果表明,選用四沖程柴油機、二沖程柴油機和蒸汽輪機作為主機的船舶數(shù)量占比分別為27.6%、72.0%和0.4%;各類型船舶配置的主機平均數(shù)量為1.01~1.82臺,副機平均數(shù)量為2.66~3.52臺,副機與主機標(biāo)定功率之比的平均值為0.19~0.35;船舶動力參數(shù)與船舶總噸之間的對應(yīng)關(guān)系可采用冪函數(shù)或線性函數(shù)表達;除集裝箱船外,近30年來,船舶動力參數(shù)與船舶總噸之間的擬合關(guān)系未發(fā)生明顯變化.
[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.
