S-ProFit (Silla Metal Propeller Retrofit Solution)
Proven Retrofit Solution for Greater EfficiencyS-ProFit is a verified propeller retrofit solution that enhances propulsion efficiency while reducing fuel consumption and CO₂ emissions—cost-effectively and reliably.
When vessel operating conditions change—such as slow steaming, altered service profiles, or tightened environmental regulations—conventional propellers may no longer deliver optimal performance. S-ProFit addresses these challenges by improving efficiency, mitigating cavitation and vibration, and ensuring compatibility with existing Energy Saving Devices (ESDs).
For container vessels, trials and simulations have shown 5–10% fuel savings on average, leading to faster ROI and compliance with regulations including EEXI and CII.
Key Success Factors
Every S-ProFit project is tailored to the vessel through diagnostics, engineering analysis, and redesign based on actual operating data. Four elements drive success:
-
Performance Assessment
Evaluation of existing propeller using CFD and operational data
-
Redesign for Power & Profile
Optimization under EPL settings and real RPM/speed profiles
-
Hydrodynamic
& Structural ValidationSimulation of hull–propeller interactions, cavitation, vibration, and fatigue life
-
Efficiency & Compliance
Optimized cost and measurable ETS reduction, with ROI typically within 1–2 years
Reliable Execution
From design through installation, S-ProFit ensures technical reliability and on-time delivery:
- Full compliance with classification society requirements
- Expert on-site installation and alignment
- Standardized procedures with high-quality materials
Lifecycle Management
S-ProFit is not just a retrofit but a long-term propeller management system. SILLA METAL supports the entire lifecycle—from initial evaluation and redesign to installation, approval, and in-service damage response—ensuring sustained propulsion performance and regulatory compliance.
