Side by side

All 2024 reports of each operator, across every ship type. Change is against 2023 where the operator reported then.

	SPRING MARINE MANAGEMENT S.A.
Ships	26
CO₂ emitted	49 kt
Fuel per mile	114 kg/nm
Average speed	9.7 kn
CO₂ at berth	8.2%
Ships burning LNG	0
Main segment	Oil tanker

Fuel per mile and speed depend on ship size and type; compare them within a segment below.

Segment by segment

Efficiency only compares within a ship type. Each row gives the CO₂ per transport work of an operator's typical (median) ship, and the bar sets it against the typical ship of the whole segment: to the left of the line it emits less CO₂ for the same transport work, to the right more.

SPRING MARINE MANAGEMENT S.A.: ships furthest from their peers

Each ship's CO₂ per transport work against the median ship of its type and size band. +100% means the ship emits twice as much CO₂ for the same transport work as a typical ship of its size. Ro-pax ships show passenger figures, with freight underneath.

30 of 26 reports shown. A high ratio can mean an older or faster-sailing ship, short trades with much time manoeuvring, or part-loaded voyages; it marks where to look first.

Notes

Companies are ISM companies (Document of Compliance holders) as named in THETIS, usually the ship manager.
Groups combine ISM companies matched on name and known ownership. If a company is in the wrong group, tell us at info@navalyze.com.
Efficiency figures use full-year reports with fuel; totals include part-year reports.
Euro figures use the EUA price set at the top of the page.
Verifier names vary by entity and year (for example DNV AS and DNV Hellas); they are rolled up into one brand. A verifier's figures cover the ships whose 2024 report it verified.
