Maximising efficiency and performance

Older propulsion systems have usually been subjected to wear and tear, and spare parts might have become obsolete and scarce. A retrofit or upgrade of e.g. the remote control system and the mechanical parts of the propulsion system can help prevent unexpected maintenance and repair periods that increase operational costs. Propulsion efficiency upgrades or installing energy saving devices brings major savings in fuel costs.

    Wärtsilä EnergoFlow

    In today’s increasingly competitive shipping environment, you need solutions that not only increase your efficiency, but that are also reliable and have a short payback period. Wärtsilä EnergoFlow is an innovative and cost-effective pre-swirl stator that increases fuel efficiency by up to 10% – without increasing maintenance needs.

    Wärtsilä EnergoFlow creates optimal inflow for the propeller by guiding one side of the stern flow in the opposite direction to the propeller rotation, generating pre-swirl. The solution consists of multiple curved fins and a ring attached to the ship’s hull to prevent the power losses that typically occur in a propeller’s slipstream.

    Wärtsilä EnergoProFin

    The Wärtsilä EnergoProFin is an energy saving propeller cap with fins that rotate together with the propeller. This solution provides average fuel savings of 2%, with a payback time of less than one year.

    The propeller’s energy losses are among the factors related to the flow phenomena around and behind the propeller boss. Installing the Wärtsilä EnergoProFin helps to reduce these energy losses and increase overall propulsion efficiency.

    The Wärtsilä EnergoProFin is suitable for all new builds and vessels in operation.

    New propeller design

    Improving fuel efficiency is considered to be the most effective way to reduce a vessel’s operating costs. 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.

    A new propeller design, along with reduced vessel speeds and engine power, can lead to propulsive efficiency improvements of up to 15%.

    Improved propulsive efficiency

    High performance nozzle

    Propulsion efficiency is one of the most effective ways of reducing operating costs. The Wärtsilä High Performance (HP) Nozzle improves propulsion efficiency resulting in increased thrust and fuel savings and performs significantly better than the industry standard nozzle types, such as the 19A or 37 type nozzles.

    Increases propulsion efficiency

    Wärtsilä Underwater services

    Performing maintenance and repairs to propellers, thrusters, rudders and stern tube seals while keeping the vessel in service enables uninterrupted operation with the best propulsion efficiency for lower fuel consumption.

    Wärtsilä Underwater Services reduce the need for vessel downtime for dry docking and the need for off-hire. By providing OEM quality maintenance, Wärtsilä’s Global Underwater Services save considerable time and money.
