Petrosea

What Petrosea does

Petrosea (PT Petrosea Tbk, IDX:PTRO) is an Indonesian integrated mining, engineering, and energy services company founded in 1972 and headquartered in Jakarta. The company operates four core business lines: Mining Services (contract mining with pit-to-port capabilities), Engineering, Procurement & Construction (EPC), Offshore Oil & Gas EPCI, and Logistics & Support Services. Its service portfolio is anchored by proprietary coal reserves of 164.1 million tons (82 million tons mineable) held through subsidiary PT Cristian Eka Pratama, an overburden removal capacity of 549 million BCM, and strategic support facilities including the Petrosea Offshore Supply Base (POSB) in Sorong and the Petrosea Support Facilities (PSF), a Bonded Logistics Center in Balikpapan.

The company leverages a Remote Operations Center (ROC) for real-time monitoring and control of multi-site operations, and has been recognized by the World Economic Forum's Global Lighthouse Network for Industry 4.0 adoption at the Tabang project. Recent AI initiatives include a Microsoft Azure cloud partnership and a first-place finish in the Microsoft Indonesia AI Hackathon 2025 for safety applications. Safety is a central operational pillar, with documented LTI-free hour milestones exceeding 49 million at the Kideco Jaya Agung project and Target Zero philosophy embedded across operations.

Petrosea generates revenue through negotiated multi-year enterprise contracts with mining companies (Kideco Jaya Agung, Kartika Selabumi Mining, PT Aneka Tambang) and energy operators (INPEX Masela), distributed across Indonesia with expanding presence in Pakistan and Australia. It is controlled by PT Kreasi Jasa Persada, a wholly-owned subsidiary of PT Petrindo Jaya Kreasi Tbk. Reported FY2025 revenue was US$886.46 million with net profit of US$35.01 million, though press coverage notes a multi-year trend of declining earnings alongside a debt-to-equity ratio of 275.6%, and Q1 2026 net income of only US$1.39M indicates compressed near-term margins despite continued top-line scaling.
