Abstract:" This paper takes the power conversion project of the 2 100 DWT inland river multi-purpose cargo ship as a case study. According to the conversion demand of the ship owner and the relevant requirements of CCS Classification Society on LNG-powered ship design, and in combination with the characteristics of the inland river cargo ship and the relevant arrangement, the key technologies such as the LNG storage tank arrangement, the classification of the hazardous area and the relevant adjustment of the general arrangement and the intact stability calibration of the retrofitted vessel are analysed and calculated, so as to complete the whole ship conversion project. The project has been well received by the ship owner and classification society, and can provide reference for the subsequent transformation of diesel-powered cargo ships into LNG-fuelled vessels.
Key words: inland river multipurpose cargo vessel;" LNG fuel power;" conversion design
1" " 引言
我國在2011年提出了實(shí)現(xiàn)內(nèi)河水運(yùn)綠色發(fā)展的具體要求,隨著天然氣(LNG)來源日益規(guī)模化、多元化、專業(yè)化,選擇LNG燃料替代傳統(tǒng)船用燃油已成為現(xiàn)實(shí)。作為一種環(huán)保能源,LNG在環(huán)境保護(hù)、經(jīng)濟(jì)效益和社會影響等方面具有顯著益處。它幾乎實(shí)現(xiàn)零硫氧化物排放,并有效減少85%以上的氮氧化物和15%以上的二氧化碳排放。本文對某2 100 DWT內(nèi)河多用途貨船LNG燃料動力改造設(shè)計進(jìn)行分析,可為后續(xù)柴油動力貨船改造為LNG燃料動力船提供借鑒。

隨著全球海運(yùn)貿(mào)易快速發(fā)展,國際海事組織(IMO)對船舶排放監(jiān)督和限制日趨嚴(yán)格,LNG作為低排放的能源選擇,成為目前最安全且減排效果最佳的船舶燃料。然而,目前我國LNG動力船的應(yīng)用仍然不多,主要原因如下:1)水上加注站的數(shù)量及配置不足;2)LNG燃料動力船的安全要求嚴(yán)格,導(dǎo)致船舶建造費(fèi)用較高。但隨著國內(nèi)支持政策的完善,技術(shù)水平的進(jìn)步,我國LNG動力船必將迎來一個高速發(fā)展的黃金時期。……
