The RDMP Balikpapan JO (Refinery Development Master Plan - Joint Operation) is a major national energy infrastructure initiative being developed by PT Kilang Pertamina Balikpapan, a subsidiary of Indonesia’s state-owned oil and gas company PT Pertamina (Persero). Its primary goal is to modernize and expand the Balikpapan refinery located in East Kalimantan, boosting its capacity from 260,000 barrels per day to 360,000 barrels per day.

The project is being executed through a joint operation involving key players such as Hyundai Engineering, Rekayasa Industri, SK Engineering and Construction, and PT PP. These firms bring together a blend of global expertise and local resources to address the engineering complexities of integrating cutting-edge technology into an existing facility. Among the technological upgrades is the inclusion of equipment capable of producing fuels compliant with EURO V standards, which means lower sulfur content and reduced emissions. New units such as the Crude Distillation Unit (CDU-IV), Hydro Cracking Units, and the Heavy Vacuum Unit have been installed or revamped to ensure efficiency and compliance with global benchmarks.
