Complimentary Propulsion Energy Efficiency Study

Eniram carried out a study onboard a 5,500TEU container vessel over the course of 136 days. During this time, the vessel completed 7 legs of its voyage, in varying weather conditions. The aim of this study was to determine the effects of the trim of the vessel on the propulsion energy.

The findings in brief are that:

  • The trim of the vessel accounts for the largest unwanted use of fuel that can be controlled

  • Thus, had the vessel been trimmed at the optimum trim, 350 tons of fuel during the course of its overall 45,900 NM journey could have been saved.

  • The average percentage fuel loss due to inaccurate trimming was 5%

  • This equates to 880 tonnes of CO2 that could have been saved with DTA

  • The vessel operators could have therefore saved $120,000 in fuel costs over the course of the 136 days.
