Abstract

Pemanfaatan gas alam dalam bentuk LNG merupakan alternatif pemecahan masalah untuk memecahkan masalah krisis tenaga listrik. Pemanfaatan gas alam tersebut tentunya harus ditunjang dengan fasilitas pendukung, dimana fasilitas pendukung yang dimaksud disini adalah ketersediaannya kapal pengangkut serta fasilitas penunjang baik dalam memproduksi, memproses, dan mendistribusikan. Analisa stress material merupakan salah satu hal yang sangat penting dalam menentukan kuat atau tidaknya sruktur konstruksi kapal. Pada proses desain diperlukan inputan volume LNG yang dibutuhkan dan perhitungan tebal plat tabung, mendesain tabung dan support tabung mini LNG. Volume LNG yang di butuhkan adalah 10000 m3. Hasil simulasi dan analisa kekuatan tabung menunjukkan nilai maksimum stress yang terjadi 55,6 N/mm2 dan nilai minimum stress 0,2 N/mm2dengan nilai strain 6,164 x 10-3, displacement 6,159 mm dan factor of safety 2,6. Sedangkan hasil simulasi dan analisa kekuatan support menunjukkan nilai maksimum stress yang terjadi 3,20646 x 108 N/m2 dan nilai minimum stress 1,29278 N/m2 dengan nilai strain 1,611 x 10-12, displacement 1,831 mm dan factor of safety 1,4. ================================================================= The utilization of natural gas in the form of LNG is an alternative to solve the problem-solving of power crisis. The utilization of natural gas must be supported with facilities support, where support facilities are meant here is the availability of ship carrying and facilities support in producing, processing and distributing. Analysis of the material stress is one of thing that is very important in determining whether or not the structures that strong ship construction. On the process design, the input required is volume of LNG that necessary, and calculation of tube plate thickness, design and support of tube tube mini LNG. The volume of LNG is needed is 10000 m3. The result of simulation and analysis show that the strength of tank, maximum value of stress that occurs at 55,6 N/mm2and the minimum of minimum stress value is 0.2 N / mm2, with a value of strain is 6.164 x 10-3, displacement is 6.159 mm and a factor of safety of 2.6. While the results of simulation and analysi the strength of support shows the maximum value of the stress that occurs 3.20646 x 108 N / m2 and the minimum stress value is 1.29278 N / m2 with a value of strain is 1.611 x 10-12, displacement is 1.831 mm and a factor of safety of 1.4.
