Perkembangan teknologi di sektor industri minyak dan gas terus meningkat,seiring dengan pro-yeksi kebutuhan energi global yang akan tumbuh sebesar 1,6% per tahun hingga 2030. Mayoritas energi dunia masih dipasok dari bahan bakar fosil, yang meicu perlunya penerapan teknologi baru di industri tersebut agar tetap kompetitif. PT Elnusa Fabrikasi Konstruksi membutuhkan mesin diesel sebagai penggerak generator berkapasitas 320 kW untuk mendukung operasional workshop baru tersebut. Mesin diesel dipilih karena efisiesnsinya dalam bekerja pada beban tinggi. Perancangan ini melibatkan data awal seperti, daya generator 320 kW, putaran mesin 1500 rpm, jumlah silinder g, efisiesnsi mekanik 75%, efisiensi transmisi 98%, efisiensi generator 93%, dan tekanan efektif rata-rata 0,95 Mpa. Kom-ponen utama yang dirancang meliputi piston, cylinder liner, connecting rood, dan crankshaft. Hasil pe-rancangan menunjukkan daya indikator sebesar 468,5 kW. Evaluasi keekonomian menunjukkan bahwa investasi sebesar Rp. 1.089.300.968 dapat kembali dalam jangka waktu sekitar 4,3 tahun dengan NPV sebesar Rp. 912.218.908 dan IRR sebesar 21,84%, yang menunjukkan bahwa proyek ini layak secara finansial.
