As far as design is concerned (i.e. hydrodynamics), DTU is correct. DTU is also correct to say that large ships can meet the Required EED. However, other comments given in this article are simply speculative, ingnoring the full picture: (a) the lightweight of ships went down over the last 40 years (too much sometimes); (b). the installed power/ship has increase because the average size of a ship has increased significantly; (c) consumption of today's engines is 30% less than it was 40 years ago; (d) 40 years ago, large ships were turbine drive, with a consumption/tonne-mile probably 50% higher tha today's consumption

As I understand EEDI is BETA index - studies showing modification to meet the challenges that face our industry - MEPC attendance on is the mark on reacting positively. I thank you Dragos for explaining the development on initiatives – we can be well pleased to learn our industry continues to have a proud history in applying technological development improving efficiencies.
Kind regards
