Abstract

The conversion of Landing Craft Tank into Livestock Carrier as an alternative solution was conducted by performing technical and economic assessments. The conversion analysis of LCT vessels to Livestock Carrier was achieved by performing layout rearrangement, stability test, seakeeping, and resistance test to measure the technical change occurring due to the modification. The economic added-value analysis was conducted by calculating the payback period to determine the estimated time needed to recover the cost of an investment. The result showed that the conversion of LCT ships has a good technical assessment. The intact and damage stability performance qualifies the standard criteria given by the IMO standard. The motion result qualifies the standard according to the type of vessel in terms of heave, pitch, and roll motions. Moreover, the resistance of the Livestock Carrier is reduced due to a decrease in displacement and draft. In terms of economic assessment, the Livestock Carrier conversion project qualifies for investment projects and improves the use-value and economy of a business segment.

登陆艇坦克改装牲畜运输车的技术评价与经济效益综述

通过进行技术和经济评估，将登陆艇坦克改装为牲畜运输车作为替代解决方案。通过对LCT船进行布局重排、稳定性测试、耐波性和阻力测试，以测量因改装而发生的技术变化，实现了LCT船向牲畜运输船的改装分析。经济增加值分析是通过计算投资回收期来确定收回投资成本所需的估计时间来进行的。结果表明，LCT船改装具有良好的技术评价。完整和损伤稳定性性能符合IMO标准给出的标准标准。根据船舶的升沉、纵摇和横摇运动类型，运动结果符合标准。此外，由于排水量和吃水深度的减少，牲畜运输车的阻力也减少了。就经济评估而言，牲畜运输车改造项目符合投资项目的条件，并提高了业务部门的使用价值和经济性。
