25年，還貸期小於8 26年。對投資的盈虧平衡進行分折結果表明，建造艙容is000m 』自航耙吸挖泥船盈虧平衡點較高，為74 -
Because the hull scale is big for large self - propelled trailing suction hopper dredgers, and the automatic degree of the equipments is high, the abroad shipyards i special of europe have the ripe experiences to build such dredgers, which with cad to guarantee the building quality and the time limit for project. relatively, the national shipyards never built such dredgers that hopper volume over 4500 m3. although building the dredgers at home, many be spare and to encourage the development of shipbuilding technique, but the building quality and the time limit foe project cannot be guaranteed
大型自航耙吸挖泥船的船體尺度大，設備裝備的自動化程度高，國外特別是歐州大型造船廠建造此類挖泥船具有成熟的經驗，他們採用電腦輔助設計和輔助建造可保證質量和工期，相對而言，國內的造船廠這些年從未建造過艙容超過4500m ~ 3的中型自航耙吸挖泥船，更沒有大型自航耙吸挖泥船的建造經歷，雖然據估算，在國內建造挖泥船可節省一些投資，又可藉此激勵國內造船技術的發展，但其建造質量和工期難以保證，權衡利弊，以選擇國外建造大型自航耙吸挖泥船的方案為好。 -
Along with lime ' s moving the vessels and equipments which been built by the national investment, one older year by year, in particular, the expensive middling self - propelled trailing suction hopper dredgers
隨著時間的推移，早先由國家投資建造的船舶機具，尤其是價值昂貴的中型自航耙吸挖泥船都逐漸老化陳舊，疏浚能力日益衰減。 -
So, it is better to select building the large self - propelled trailing suction hopper dredgers abroad. however, the modern dredger is not only a technique a alone together but property article, especially large self - propelled trailing suction hopper dredger
然而，現代疏浚船舶尤其是大型自航耙吸挖泥船不僅是一種技術密集型的商品，更是一種資產密集型的商品，耗資之巨非上海航道局的財力所能承受。 -
A trailing suction hopper dredger is one of the most popular dredging tools for regulation of waterway and harbors. it is a large self - propelled and self loaded dredger which can be used in wide water area such as an estuary or a river mouth. it is adaptive economical, it is widely used in large dredging projects in most countries in the world
