Potential consequence on safety
Safety should not be compromised in seeking
- Manoeuverability of the ship might be jeopardizedwhen a vessel is under-powered in order to
minimize EEDI.
- Redundancy in propulsion and safe return to port
arrangements.
- IMO (MSC and MEPC) have recognized the topic and
will come up with Guidelines.

Conclusions
EEDI and SEEMP will decrease the emissions

not alone manage to curb the growth of GHG emissions.
Marked based instruments (MBI) will be required.
