A thought provoking series of sessions on the second day of this year's Red Ensign Group conference.
There was a sobering session as the Coastal States forum considered why good ship waste management systems matter in the ongoing battle against marine 'litter'.
Delegates are from some of the most environmentally precious places on the planet so interest in how to offset the impact of that is very high.
Safety of vessels, care for the marine environment, future fuels for cleaner greener shipping - just three of the topics to come under discussion today.
