Troubleshooting & Optimisation Capabilities
Optimisation of 7x Wärtsilä Engines + Steam Turbine
IPP with 7x Wärtsilä 18V50 Dual Fuel Engines and 9.55 MW Shin Nippon Steam Turbine experienced reduced power generation. Root causes included improper HRSG heat transfer, poor condenser performance, and cooling water inefficiencies.
- Inadequate soot blowing system
- Design deficiencies in cooling circuits
- Pumps operating outside performance curves
- Continuous operation of radiator fans
Deployed a Troubleshooting Specialist to implement a technical roadmap:
- Optimised soot blowing sequences
- Enhanced condenser vacuum performance
- Re-balanced cooling water system
- Implemented proper insulation strategies
Result: Increased output, improved efficiency & energy savings.
