Elogrid is a patented tunnel thruster grid that improves maneuverability, lowers fuel consumption and helps vessels comply with the Carbon Intensity Indicator (CII) and other upcoming rules and regulations.

This state-of-the-art product, designed with Elomatic’s computational fluid dynamic (CFD) simulations, is set in a ship’s tunnel openings to prevent water from undesired swirling in the tunnels. The Elogrid blades are set in a radial direction to decrease swirl and increase jet axial momentum. Each Elogrid is custom designed based on the vessel-specific hull form and flow direction, enhancing the entire ship solution.

What’s in it for you?

  • Fuel savings that guarantee a short payback period
  • Improves maneuverability for RoPax, cruise and dynamic positioning operating vessels
  • Reduces friction during long-haul transits
  • Lowers noise and vibration
  • Properly dimensioned with 3D geometry to best adapt to the vessel hull
  • Stainless steel material ensures long lifetime and durability for harsh conditions

Performance verified with measurements on aboard Viking Line M/S Gabriella.
Four Elogrids were delivered for the vessel’s two 2.4 m tunnels.

  • Fuel savings – of up to 2.5%
  • Thrust improvement of 5–15% depending on power
  • Noise decreased by 2 dB(A) from 61 to 59 dB(A)
  • Vibration was reduced by 15–30% on average
“After Elogrids were installed, I really felt a difference in lower deck vibrations, even during testing. The maneuverability of the vessel has clearly improved compared to what it was originally. I would not have expected to notice such a significant effect. The personnel I have met from Elomatic have all been true professionals.”
– Captain Tomas Karlgren of Viking Line
