NAVIGATOR PLUTO against its type

Built in 2000, it is 13 years older than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 17,840 gross tonnage it is smaller than 62% of the other 525 gas carriers with a recorded tonnage. It is one of 131 gas carriers here under the Liberia flag, 19.0% of the 688 on the register. Thome Ship Management is linked to 42 vessels on this register. The returns for 2022–2025 all give Monrovia as port of registry.

Its 2,679 t of CO₂ for 2025 is 55% below the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 291.8 kg CO₂, 14% above the type median of 256.2 kg. It logged 810 hours at sea against a median of 1,943 hours for its type that year. 0.9% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Its efficiency percentile within the type went from 62 in 2022 to 65 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 190 of 292 qualifying gas carriers by EEOI, at the 65th percentile. The dashed line is the type median, 27.9; this vessel reported 41.0.

0255075100more efficientless efficientThis vessel: 65th percentile, EEOI 41.0

Across the 39 ranked vessels operated by Thome Ship Management, the median percentile is 54. This vessel is less efficient than its own fleet median.

EEOI divides emissions by transport work, which for this vessel and year was 65,269,250 tonne-miles over 9,181 nautical miles.

Reported CO₂ by year

2022: 10,270 t202210,2702025: 2,679 t20252,679

Reported CO₂ in 2025 was 73.9% lower than in 2022, for EU/EEA voyages only. No return is recorded for 2023, 2024, so the series has gaps.

From 2022 to 2025, emissions fell 73.9% while distance sailed fell 73.2%and CO₂ per nautical mile fell 2.8%.That points mainly to how much the vessel sailed, rather than the other.

Sources and how to read this

This page draws on 2 MRV reporting years, an efficiency ranking and 4 of 5 vessel particulars. Not found in the sources for this vessel: AIS movements in Norwegian waters, a name history, a licensed photograph, a sanctions listing and US port state inspections.

Empty means unreported, never zero. How EEOI, distance, percentiles and sister ships are handled is explained under reading a vessel page. Something wrong? See corrections.
