Okeanis Eco Tankers expects older vessels will have to reduce their speed by as much as 35% to meet new efficiency rules.
Under new International Maritime Organization standards, ships will have to comply with efficiency and emissions limits that are about a 15% to 20% improvement on historic standards set out in a 2008 baseline.
Okeanis chief operating officer Aristidis Alafouzos told analysts on a conference call that charterers, owners and entire communities are applying much more attention to vessel emissions.
