K-VG
K-VG (KRISO Vortex Generator)
Shaping the flow. Boosting efficiency.
K-VG is a stern-mounted energy-saving device that reduces hull resistance and improves propeller inflow. By generating controlled vortices, K-VG smooths the wake field, lowering propulsion power demand while also mitigating cavitation, vibration, and underwater radiated noise.
How It Works
- Induces streamwise vortices along the hull surface
- Energizes low-velocity flow at the stern, recovering wake pressure loss
- Guides high-momentum fluid toward the propeller inflow
- ResultReduced resistance and improved propeller efficiency
Key Features & Benefits
- Fuel savings: up to 5% (ballast), 2–3% (laden)
- Simple, low-cost installation suitable for retrofits and newbuilds
- Short ROI with proven performance
- Reduced cavitation, pressure pulses, vibration, and URN
👉 With proven performance, short ROI, and simple installation, S-Cap is the practical solution for shipowners seeking efficiency gains without complexity.
Application Record
| Vessel Type | Savings | Status |
|---|---|---|
| 145K Steam LNGC | 2.3% laden / 3.1% ballast (CFD) | Retrofit (Jun 2025) |
| 180K Bulk Carrier | 2.1% laden / 5.3% ballast | Retrofit (planned) |
| 60K Bulk Carrier | 3.0% laden / 5.0% ballast | Newbuild (HMD) |
| 55K DWT Tanker | 2.9% laden | Newbuild (GSI) |
| 34.5K Bulk Carrier | 3.2% laden | Newbuild (Sanfu) |
👉 With verified efficiency, quick payback, and ease of installation, K-VG offers shipowners a practical solution to improve performance and cut operating costs—whether for retrofits or newbuilds.
