The Wärtsilä Efficiency Upgrade with new propeller design – improve efficiency and reduce emissions

Improving fuel efficiency is considered as one of the most effective ways to reduce a vessel’s operating costs and fuel consumption. The new Wärtsilä propeller design is considered an energy-saving technology reducing also emissions and improving CII rating. A new propeller design, along with reduced vessel speeds and engine power, can lead to propulsive efficiency improvements of up to 15%.

Redesigning the propeller can lead to significant efficiency gains for vessels that employ slow steaming to save fuel, but also for fast ferries, which can achieve higher speeds and efficiency gains with modifications to controllable-pitch propeller (CPP) blades.

Key benefits

  • Improve propulsive efficiency by as much as 15%
  • Reduce emission levels, pressure pulses and underwater noise
  • Short payback period – typically 2 to 3 years

    Technical info

    The performance of the current propeller as well as the interaction between the propeller and hull is analysed by using computational fluid design (CFD). See further technical information from the brochure.

    Application

    Available for all CPPs and FPPs.
