Elogrid

Elogrid™ is Elomatic's tunnel thruster solution. It is installed in the thruster tunnel openings of a vessel and custom-designed with computational fluid dynamics (CFD) for each hull shape, thruster configuration and operational profile. With thrusters inactive it reduces the resistance and windmill effect of open tunnels; with thrusters in use it optimizes flow to and from the thruster propeller, giving stronger side thrust and less cavitation.

Key features

• Fuel savings of 1-4% depending on vessel and operation
• Side thrust improvement of over 10%, confirmed by an independent Bureau Veritas Solutions CFD evaluation in 2025 (less than 5% difference to Elomatic's own CFD results)
• Approx. 25% reduction in tunnel vibration and approx. 2 dB(A) reduction in airborne noise
• Laser scanning of tunnel openings at drydock for millimeter-level prefabrication
• Installed during regular drydocking; available for newbuilds and retrofits

Applications

Cruise ships, ferries, RoPax, offshore support vessels and cargo ships. Installed on vessels of Carnival Corporation's XL-Class fleet, Viking Line (e.g. Viking Grace) and Stena Superfast VIII, among others.
