  • Establish and improve best practices with insights from speed reports and Wärtsilä fleet

Case: Save with Wärtsilä Speed

Wartsila Speed Case

Many vessels play it safe for on time arrival – speed up in the beginning of the voyage to buffer time and sail very slowly at the latter part of the voyage. The fuel saved during the slow part of the voyage is never enough to cover the extra fuel needed for higher speed. On an example voyage of 3649 nm, an LNG carrier would have saved 4.9 tons of fuel by utilizing Wärtsilä Speed recommendation instead of traditional speed planning practices.


The Insight Factory

How it works

The Insight Factory

We continuously collect data from bridge and automation systems, weather forecasts, and sensors.

The data is continuously analyzed by Wärtsilä’s advanced mathematical models tailored to each vessel to identify the optimum RPM profile for the remaining voyage.

The optimum RPM is displayed on the bridge and the teams are kept up-to-date with mobile notifications, Wärtsilä Fleet and Speed reports.


Wärtsilä Speed optimised by Eniram

Wärtsilä Speed recommends the optimal RPM to reach port just in time at the lowest cost. All analysis is based on a unique model of your vessel’s hydrodynamic characteristics. This is combined with real-time information gathered by bridge and automation systems, sensors on the vessel hull and with weather forecasts.

The service automatically receives route information from navigation systems. Based on the set ETA, the Wärtsilä Insight Factory continuously calculates the optimal RPM profile for the remaining voayge, using advanced algorithms.

The solution also offers recommendations for diesel-electric propulsion to balance the required engine load and ensure optimum engine combinations. With Wärtsilä Speed, your vessel burns no more fuel than is necessary to maintain the desired speed and service power requirements in the prevailing conditions.
