Therefore, in the development of large vessels, it will be inevitable to have some safety problems. Like the nuclear plant accident in Japan, when they first built the plant, they did not predict that such accident could happen in the future. They could only make the solution they considered best and establish corresponding standards and rules in the light of the existing technical conditions and backgrounds. In fact, shipbuilding industry is the same. Though the technical solutions have bee advanced and varied, there are still many uncertainties as to whether the existing experience and ability can cope with the development of large vessels. 大型船舶的限制 2 月 21 日,被業(yè)界震驚的消息, AP 穆勒 馬士基集團下訂單的 10 與韓國造船廠 18,000 TEU 集裝箱船。 在每一段時間中,大型船舶的發(fā)展面臨著許多制約因素。 陳擁輦 CCS 研發(fā)中心 認為,雖然有方面的理論和技術的發(fā)展,大型船舶的先決條件,安全問題不能被低估。因此,在大型船舶的發(fā)展,這將是不可避免的,有一些安全問題。雖然技術解決方案已經成為先進和多樣的,仍然有很多的不確定性,現有的經驗和能力是否能夠應對大型船舶的發(fā)展 。 他們只能使他們認為是最好的解決方案,并建立相應的標準和規(guī)則,在現有的技術條件和背景光。 在傳統(tǒng)理論中,與一般的大小的增加,承受波浪的能力將得到更強。 AP 穆勒 馬士基集團和韓國船廠的優(yōu)異性能集裝箱船在該地區(qū)是一個很好的例子,這是值得更多的關注和研究,從中國的港口業(yè),造船業(yè),航運業(yè)及相關行業(yè)。 就目前的發(fā)展趨勢,大型船舶,江南造船(集團)公司總工程師有限公司胡先生科藝認為,從理論和技術的角度來看,大型船舶的發(fā)展是沒有問題的,即使有 問題 ,發(fā)展船舶的大小是由許多因素 決定 ,如通道,港口,碼頭的深度和船東攬貨能力。 The limit of Large Vessels on Feb 21st, the industry was shocked by the news that AP MollerMaersk placed an order of 10 container ships of 18,000 TEU with the South Korean ship yards. The order brings the development of large vessels to a new climax and at the same time puts forward a series of research subjects to the industry, such as what is the limit for the development of large vessels, whether ship safety can be guaranteed, and etc. In relation to the current development trend of large vessels, the chief engineer of Jiangnan Shipbuilding (Group) Company Ltd. Mr. Hu Keyi believes that from the perspective of theory and technology, there is no problem with the development of large vessels, even with the development of “infinitely large vessels”, however, the size of ships is limited by many factors such as channels, ports, wharf depth and the ability of cargo collection of shipowners. Therefore, such infinite largeness is relative. In every period of time, the development of large vessels faces many constraints. However, as seen from the history of development (in particular container ships), each limit value predicted by experts has been broken one by one. This gives an enlightenment to the industry
