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
