【摘要】：海上運輸作為全球物流運輸中的重要一環(huán),世界上絕大多數貨物貿易都是經由船舶轉運的。海上運輸具有運費低、運輸量大、裝卸效率高,通過能力強等諸多優(yōu)點,因此被世人廣泛利用。但是傳統船舶有一個嚴重的問題,由于需要攜帶大量的壓載水,帶來的海洋生態(tài)環(huán)境問題必須引起人們的高度重視。壓載水的使用和排放問題,導致的海洋環(huán)境污染,引發(fā)外來生物入侵等問題,被全球環(huán)�；鸾M織列為海洋的四大危害之一。隨著《2004年國際船舶壓載水和沉積物控制與管理公約》的實施和各國對海洋環(huán)境保護的重視,船舶安裝壓載水處理系統已逐漸得到船東的認可和接受。但是這些設備并不能完全消除壓載水帶來的諸多問題,同時傳統船舶空載時攜帶的大量壓載水必然隨之帶來船舶能耗加大,壓載艙的設置還會造成寶貴艙容的損失等。為了能較好的解決壓載水帶來的諸多問題,人們希望能夠設計一種只需要少量壓載水就能滿足航行要求的船舶。針對使用壓載水帶來諸多問題,首先,本文結合最新的V型低壓載水船設計理念,以45000DWT散貨船為母型船,通過型線變換對母型船進行的一系列船身變換,使母型船變?yōu)閂型低壓載水散貨船,并滿足三向光順。其次,對于新船型進行總布置研究,包括劃分艙室、結構設計等初步設計。最后,通過計算分析V型低壓載水散貨船和母型船的各項性能,主要包括船舶靜水力、靜穩(wěn)性、動穩(wěn)性、耐波性、運動響應等,通過對比來確定新的散貨船船型的各項性能優(yōu)劣。通過本文的設計和計算,最終得出一種低壓載水型散貨船的初步設計方案,并探討該V型船設計方案的可行性。通過與母型船的對比,說明新船型相對于母型船各方面的性能優(yōu)劣,并給出一些低壓載水散貨船設計的有益結論,指出其中尚需改進之處,相信對今后低壓載水散貨船的研究來說具有一定的參考價值,對其它類型低壓載水船舶的設計有一定的借鑒意義。
[Abstract]:As an important part of global logistics transportation, the vast majority of goods trade in the world is transported by ships. Marine transportation is widely used by the world because of its advantages such as low freight, high transportation, high handling efficiency and strong ability to pass through. However, the traditional ship has a serious problem. Due to the need to carry a large amount of ballast water, the problem of marine ecological environment must be paid more attention to. Problems such as the use and discharge of ballast water, the marine environmental pollution, and the invasion of alien creatures are listed as one of the four major hazards of the ocean by the global environmental protection fund. With the implementation of the Convention on the control and management of international ballast water and sediment in 2004 and the importance of marine environmental protection by various countries, the ballast water treatment system for ships has been gradually recognized and accepted by the shipowners. However, these devices can not completely eliminate many problems caused by ballast water. At the same time, a large number of ballast water carried by traditional ships will inevitably bring more energy consumption, and the installation of ballast tanks will also cause the loss of valuable cabin capacity. In order to better solve the problems caused by ballast water, people hope to be able to design a ship that needs only a small amount of ballast water to meet the requirements of the navigation. For the use of ballast water brought many problems, first of all, this paper combines the V type low-voltage latest design concepts of ballast water in ships, 45000DWT bulk cargo ship for the parent ship, a series of the transform of the parent ship through the transformation in line, the parent ship for V type low voltage load water bulk carrier, and three to meet the fairing. Secondly, the general layout of the new ship type is studied, including the preliminary design of the compartments and the structural design. Finally, the performance through the calculation and analysis of V type low voltage load water bulk carrier and the parent ship, including ship statics, static stability, dynamic stability, seakeeping, motion response, by contrast to determine the performance of the new bulk cargo ship. Through the design and calculation of this paper, a preliminary design scheme of low pressure water carrier bulk carrier is finally obtained, and the feasibility of the V ship design scheme is discussed. By comparison with the mother ship, that ship with respect to the performance of the parent ship, and gives some useful conclusions low water bulk carrier design, which still need to be improved, I believe it for future research on low load water bulk carrier has a certain reference value, design reference for other types of low-voltage ballast water ship.
