Target Applications in Indonesia
- Refinery Gas Compressors: Hydrogen, wet gas, and recycle gas compressor drive trains at Pertamina refineries (Balikpapan, Cilacap, Balongan, Plaju).
- Power Generation: High-hour diesel and natural gas engine generator sets requiring torsional resonance mitigation.
- Marine & Offshore: Tugboats, patrol craft, crew vessels, and offshore supply vessels (OSVs) requiring propulsion thrust isolation.
