Elogrid

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.

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.”
