VEEM Limited is pleased to announce that it has launched its most efficient propulsion system yet, the VEEM Extreme propulsion package.

The VEEM Extreme propulsion package consists of VEEM propeller, twisted rudder and fully flow-aligned shaft line package including V and P bracket made in VEEM’s new proprietary high -tensile alloy which is VEEM’s fastest and most fuel-efficient inboard package yet and reduces fuel consumption by 18.1% against a standard set up. All testing was witnessed by Lloyd’s Register on VEEM’s test vessel.

At the centre of this advancement is the VEEM Extreme propeller, manufactured from a proprietary high-tensile alloy that enables thinner blade profiles and better performance resulting in fuel efficiency gains; reduced carbon footprint and speed gains.

Compared with an industry-standard, Class 1, hand profiled propeller, the new VEEM Extreme Propellers delivered an 11.9% reduction in fuel burn and carbon footprint with a top speed improvement of 3.36 knots, to 43.05 knots. They also demonstrated improvements in efficiency and speed over the current VEEM fully CNC machined NiBral propellers, with a reduction of 6.2% in fuel burn and speed improvements of 0.89 knots.

Integrating with the VEEM Extreme propeller is the complete, flow-aligned shaft package, which includes:
oVEEM Extreme flow-aligned rudder with NACA sections manufactured in the VEEM Extreme alloy which resulted in 72% less drag and 6.2% less fuel burn than a standard parallel plate rudder commonly used in the marine industry.

oVEEM Extreme V and P brackets are also designed in the VEEM Extreme material, are flow aligned and will be tested in the near future with further small gains expected.

oVEEM Extreme shaft that utilises a proprietary registered design to attach to the propeller and coupling, reducing stress by 20% over a standard shaft and keyway design. This allows smaller diameter shafts to be used with smaller bracket and propeller boss diameters and will be tested in the near future with further small gains expected.

VEEM has successfully completed a VEEM Extreme propeller only trial on a Manly Fast Ferry which during trials confirmed the performance gains found on the VEEM test vessel. Manly Fast Ferries is now planning to convert 6 more vessels to VEEM Extreme propellers over the next 18 months, with contract negotiations underway.

Further to this as a result of VEEM’s successful VEEM Extreme rudder testing, Manly Fast Ferries have advised they intend to conduct a trial with the VEEM Extreme rudder with a view to including the VEEM Extreme rudder as part of the VEEM Extreme propeller conversions mentioned above, provided the trial result is consistent with VEEM’s testing.

VEEM Managing Director Mark Miocevich said: “Today’s announcement is the culmination of a tremendous amount of engineering development which sees VEEM remain at the global forefront of the products it produces. We’ve engineered our most efficient inboard shaft driven propulsion system yet and have the witnessed data to prove it. Manly Fast Ferries are an early validation of the product and we are pleased with their intention to add more of the VEEM Extreme range to their vessels.”
