PROJECT PORTFOLIO : DETAILED CASE STUDIES
1. PLTU Lontar Extension 315 MW Project
- Project Type: Critical Power Infrastructure Construction
- Client / Owner: PT PLN (Persero) / Main Contractor Network
- Location: Banten, Indonesia
- Capacity: 315 Megawatts (MW)
- Execution Period: Completed
Project Overview
PT Nusareka Prima Engineering was contracted to execute high-precision mechanical installation and piping networks for the 315 MW coal-fired power plant extension. This critical infrastructure project required adherence to strict international boiler codes and high-pressure system safety standards.
Detailed Scope of Work
- Boiler Pressure Parts: Assembled and positioned critical boiler pressure components, ensuring perfect alignment under tight thermal expansion tolerances.
- High-Pressure Piping Systems: Fabricated and installed the complete critical piping network, including:
- Main Steam Lines (carrying superheated steam to the turbine)
- Cold & Hot Reheat Systems
- High-Pressure Feed Water Piping
- Rigorous Testing & NDT: Conducted comprehensive hydrostatic testing up to design-critical pressure points and coordinated Non-Destructive Testing (NDT) to guarantee zero-defect welding lines.
- Thermal Insulation: Applied heavy-duty industrial lagging and thermal insulation across all high-temperature piping assets to prevent energy loss.
2. PT DSSP Power Plant Operations Support
- Project Type: Energy Infrastructure Development & Manpower Deployment
- Client / Owner: PT DSSP Power (Dian Swastatika Sentosa)
- Location: Bayung Lencir, South Sumatra, Indonesia
- Status: Completed
Project Overview
To ensure seamless construction milestones and mechanical reliability at the DSSP Power Plant asset, Nusareka mobilized highly specialized technical teams. The project focused on bridging technical engineering gaps and executing plant structure validations under rigid safety timelines.
Detailed Scope of Work
- Technical Manpower Mobilization: Deployed a dedicated field unit consisting of certified piping engineers, mechanical supervisors, and QA/QC inspectors.
- Mechanical Validation: Assisted in the structural evaluation, mechanical alignment, and pre-commissioning phases of the power plant equipment.
- HSE Compliance Control: Embedded expert Health, Safety, and Environment (HSE) personnel to enforce heavy-industrial safety protocols, achieving zero-accident milestones during our execution tenure.
3. Indah Kiat Pulp & Paper (IKPP) Onsite Services
- Project Type: Long-Term Industrial Plant Maintenance & Construction
- Client / Owner: PT Indah Kiat Pulp & Paper Tbk (Sinar Mas Group)
- Location: Perawang (Riau) & Serang (Banten) Facilities
- Status: Ongoing / Long-Term Contract
Project Overview
Heavy manufacturing facilities like pulp and paper mills operate under continuous high-stress production cycles. Nusareka provides long-term, structural construction maintenance and swift mechanical adjustments to prevent costly plant shutdowns.
Detailed Scope of Work
- Onsite Mechanical Maintenance: Executing scheduled and emergency repair work on heavy rotary equipment, industrial boilers, and chemical transport pipelines.
- Structural Retrofitting: Fabricating and erecting supplemental steel structures and technical platforms to safely upgrade existing processing lines.
- Shutdown (Turnaround) Services: Providing high-capacity technical labor forces during annual mill shutdowns to complete massive overhaul targets within minimal time windows.
4. Heavy Industrial Earthworks & Infrastructure Foundations
- Project Type: Heavy Civil Engineering
- Location: Strategic Industrial Zone, West Java, Indonesia
- Status: Completed
Project Overview
Before any industrial machinery or power plant can be erected, the ground must be engineered to withstand massive static and dynamic loads. This project covered the complete civil preparation phase for a major manufacturing site.
Detailed Scope of Work
- Mass Earthworks: Executed large-scale site clearing, bulk excavation, and controlled soil compaction using advanced heavy machinery networks.
- Deep Structural Foundations: Formed and poured heavy reinforced concrete foundations designed specifically to mitigate heavy equipment vibration and long-term soil settlement.
- Industrial Site Drainage: Built heavy-duty concrete drainage networks and retaining walls to secure the plant site against flash flooding and soil erosion.
