Overhaul of Guangzhou 6320ZC Main Engine and TPL 67 Turbocharger on MV DE MI
ANSAC's turnkey repair service for MV DE MI, involving the complete overhaul of the Guangzhou 6320ZC main engine, reconditioning of the TPL 67 turbocharger, and maintenance of the air cooler.

Technical Report: Power Optimization for MV DE MI
Following reports of main engine power loss and high exhaust gas temperatures, ANSAC's specialized in-house engineers mobilized to execute an integrated overhaul of the propulsion plant on MV DE MI[cite: 104, 107].
Core Technical Scope:
- Guangzhou 6320ZC Main Engine Overhaul: Replacements of wearing parts, intake/exhaust valve clearance adjustment, and cylinder head seat grinding[cite: 107].
- TPL 67 Turbocharger Overhaul: Complete dismantling of the turbine and compressor wheels, chemical/sand-blast decarbonization, high-speed bearing replacement, and dynamic balancing of the rotor assembly[cite: 107].
- Air Cooler Maintenance: Chemical descaling of seawater tubes and pressure leak-testing to optimize air charging temperature and density[cite: 107].
Project Milestones:
The turbocharger performance stabilized with zero vibration. Black smoke and exhaust temperature anomalies were completely resolved, allowing the vessel to safely resume its logistics schedule on time[cite: 107].
