NAVIGATOR GALAXY against its type

Built in 2011, it is 2 years older than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 16,823 gross tonnage it is smaller than 66% 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. The same builder is recorded for 761 other vessels here, 100 of them gas carriers. The returns for 2020–2025 all give Monrovia as port of registry.

Its 19,762 t of CO₂ for 2025 is 3.3 times the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 231.7 kg CO₂, close to the type median of 256.2 kg. It logged 7,082 hours at sea against a median of 1,943 hours for its type that year. 2.9% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 6 years with reported emissions, the highest was 2025 (19,762 t) and the lowest 2020 (4,657 t). Its efficiency percentile within the type went from 56 in 2020 to 54 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 159 of 292 qualifying gas carriers by EEOI, at the 54th percentile. The dashed line is the type median, 27.9; this vessel reported 31.7.

Reported CO₂ in 2025 was 324.3% higher than in 2020, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 19.8% while distance sailed rose 7.0%and CO₂ per nautical mile rose 12.0%.That points mainly to how efficiently it sailed, rather than the other.

Sources and how to read this

This page draws on 6 MRV reporting years, an efficiency ranking, 5 of 5 vessel particulars and AIS movements in Norwegian waters. Not found in the sources for this vessel: 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.
