【摘要】：經(jīng)歷了持續(xù)幾年的市場(chǎng)低迷,修船業(yè)要在逆流中求發(fā)展,轉(zhuǎn)型改革勢(shì)在必行。船舶改造工程項(xiàng)目近年來(lái)在修船業(yè)務(wù)中所占比例逐漸提高,特別對(duì)于貨船來(lái)說(shuō),相比于完全新造出一條船舶,僅僅通過(guò)改變船舶的主尺度,如船體的加長(zhǎng)、加寬或加深等手段來(lái)對(duì)船舶進(jìn)行擴(kuò)容改造,所需人力、物力及耗時(shí)都要少很多。盡管主尺度的改變,特別是對(duì)于船體貨艙區(qū)域的加長(zhǎng)改造,可能會(huì)讓船體的穩(wěn)性、強(qiáng)度等面臨一定的風(fēng)險(xiǎn),但只要采取合理的工藝方案,就可以讓船東在最短時(shí)間內(nèi)、利用最少投資,降低運(yùn)營(yíng)成本、提高效益。隨著修船企業(yè)工藝技術(shù)的不斷成熟,改造需求會(huì)逐漸增多。本文主要對(duì)船舶加長(zhǎng)改造工程進(jìn)行了分階段的工藝研究。船舶加長(zhǎng)改造通常是在平行舯體適當(dāng)位置處將船體環(huán)口切割一分為二,然后將新加分段嵌入其中。本文將船舶加長(zhǎng)改造分為三大主要工藝過(guò)程,包括新加分段的制作、船體切割分離、合攏焊接等步驟;以國(guó)內(nèi)修船行業(yè)目前所具備且常用的設(shè)備設(shè)施及相對(duì)成熟的工藝技術(shù)為基礎(chǔ),以某集裝箱船的加長(zhǎng)改造工程為例,進(jìn)行各關(guān)鍵階段的工程方案對(duì)比、改造思路拓展、施工流程分析、工藝要點(diǎn)總結(jié)等研究工作,結(jié)合層次分析計(jì)算法以及過(guò)往施工經(jīng)驗(yàn),為該項(xiàng)目各階段選取和編制合理的施工工藝方案及工藝流程,力求達(dá)到新舊分段的完美對(duì)接,以保證加長(zhǎng)后的船體可以更快適應(yīng)所在水域的航運(yùn)條件、保證長(zhǎng)期安全穩(wěn)定地運(yùn)行;同時(shí)在前文研究的基礎(chǔ)上提出一些新工藝方案設(shè)想。希望可以通過(guò)本文給修船業(yè)在船舶加長(zhǎng)改造工藝技術(shù)方面提供一份系統(tǒng)性的工藝參考,并能為今后業(yè)內(nèi)同行在船舶改造工程方案的選取和研發(fā)上拋磚引玉。
[Abstract]:After several years of market downturn, ship repair industry in order to develop against the current, transformation and reform is imperative. In recent years, the proportion of ship renovation projects in ship repair business has gradually increased, especially for cargo ships, compared with a completely new ship, it is only by changing the main scale of the ship, such as the lengthening of the hull, It takes less manpower, material and time to enlarge and transform the ship by widening or deepening. Although the change of the main scale, especially the lengthening of the ship's cargo cabin area, may make the ship's stability and strength face certain risks, as long as a reasonable technological plan is adopted, the shipowner can be allowed to do so in the shortest possible time. Use the least investment, reduce operating costs, improve efficiency. With the continuous maturity of shipbuilding technology, the demand for renovation will increase gradually. In this paper, the process of ship lengthening and revamping is studied in stages. Ship lengthening is usually done by cutting the hull ring in two at the proper position of the parallel midship, and then embedding the new section in it. In this paper, the ship lengthening and transformation is divided into three main technological processes, including the manufacture of new sections, hull cutting and separation, closing welding and so on. Based on the equipment facilities and relatively mature technology of the domestic ship repair industry, and taking the lengthening and reforming project of a container ship as an example, the project schemes of each key stage are compared and the transformation ideas are expanded. Construction process analysis, key points summary and other research work, combined with the analytic hierarchy process calculation method and past construction experience, for each stage of the project to select and compile a reasonable construction process plan and process, This paper tries to achieve the perfect docking of the new and old sections in order to ensure that the lengthened hull can adapt to the shipping conditions of the water area more quickly, and ensure the long-term safe and stable operation. At the same time, some new technological schemes are put forward on the basis of the previous research. It is hoped that this paper can provide a systematic technological reference for the shipbuilding industry in the aspect of ship lengthening and revamping technology, and can be used as a reference for the selection and development of shipbuilding engineering schemes in the industry in the future.
