Dalam rangka meningkatkan efisiensi energi, PT. KPI RU II Dumai melaksanakan Proyek Penggantian 2 (dua) Unit Driver Engine Pompa S. Rokan dengan motor listrik serta penambahan Variable Speed Drive (VSD). Dengan perubahan sistem driver tersebut, maka perlu dilakukan penyambungan listrik ke PLN 20 kV. Efisiensi yang berhasil dilakukan setara dengan nilai Rp31.941.504.000 / tahun atau total Rp766.596.096.000 selama 24 tahun dari usia proyek yang direncanakan. Berdasarkan Cost Benefit Analysis (CBA), proyek ini sangat layak dengan nilai keekonomian berdasarkan NPV sebesar USD 11.497.979 (Positif), IRR 76,51% (IRR>11,03%), PBT hanya dalam waktu 1,5 Tahun dan BCR sebesar 6,37 kali. Penerapan K3L dalam praktik keinsinyuran terdiri dari analisis bahaya dan dampak resiko serta bagaimana mengurangi dampak resiko tersebut. Penerapan kode etik, etika profesi dan profesionalisme dilakukan merujuk kepada Kode Etik Insinyur 2021 yang ditetapkan oleh Sidang Khusus Majelis Kehormatan Etik pada tanggal 18 Desember 2021 di Bali.
