Operators

The 2019 public files do not name the companies managing each ship, so operator rankings start in 2024.

Efficiency by ship size

Bigger ships move a tonne of cargo for less fuel, so ships are compared within size bands. Each row is drawn against the segment median.

Notes

  • Medians and rankings use 1,788 full-year reports with fuel; part-year and zero-fuel reports count towards totals only.
  • THETIS reports time at sea on EU-scope voyages only, not time in port. CO₂ at berth is the closest measure of port activity it publishes.
  • Speed and distance are derived from the published ratios; THETIS has no distance column.
