New ecospeed EFMS algorithm identifies optimum vessel speed for maximum fuel efficiency

Diesel power specialist Royston has developed a special ecospeed analysis capability as part of its enginei electronic fuel management system (EFMS) to enable ship operators to identify and maintain optimum vessel speeds for efficient fuel usage.


Devised with marine engineering specialists from Newcastle University, Royston has developed a new ecospeed algorithm based on speed modelling and an analysis of vessel operating data, correlating and synchronising information from different sensors installed on the vessel.


Ecospeed calculates a unique optimum performance profile for individual vessels by taking into account a range of shipping data including fuel use, speed and distance, as well as sea state, wind speed and current.
