Ship Energy Use Sankey Diagram, DNVGL

The last Sankey diagram from the maritime sector I presented in this post receievd was shared a couple of times, so here is another one from the same topic area. Sorry, but this one is a little bit blurry even in the original document.

Taken from page 8 of the 2014 report ‘Next Generation Energy Management’ by DNVGL AS (authors George Dimopoulos, Nikolaos Kakalis).

Losses branch out as dark grey arrows. From the 100% energy in fuel only 28.9% are used as propulsive thrust, some other 5.6% as on-board electricity, heat or service steam.

Many more Sankey diagrams in the same report, check out figures 9, 12, 16 and 17.
