NAVIGATOR LUNA against its type

Built in 2018, it is 5 years newer than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 16,306 gross tonnage it is smaller than 69% 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. Its MRV returns name it PACIFIC VENUS for 2019–2021 and NAVIGATOR LUNA for 2022–2025. The reported port of registry changed: Hong Kong (2019–2021), then Monrovia (2022–2025).

Its 10,183 t of CO₂ for 2025 is 1.7 times the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 218.5 kg CO₂, 15% below the type median of 256.2 kg. It logged 3,391 hours at sea against a median of 1,943 hours for its type that year. 2.2% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 6 years with reported emissions, the highest was 2022 (10,884 t) and the lowest 2023 (2,079 t). Its efficiency percentile within the type went from 33 in 2019 to 65 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 189 of 292 qualifying gas carriers by EEOI, at the 65th percentile. The dashed line is the type median, 27.9; this vessel reported 40.8.

EEOI divides emissions by transport work, which for this vessel and year was 249,397,012 tonne-miles over 46,597 nautical miles.

Reported CO₂ in 2025 was 215.6% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.

From 2023 to 2025, emissions rose 389.9% while distance sailed rose 307.7%and CO₂ per nautical mile rose 20.2%.That points mainly to how much the vessel sailed, rather than the other.

Sources and how to read this

This page draws on 6 MRV reporting years, an efficiency ranking, 4 of 5 vessel particulars and a name history. Not found in the sources for this vessel: AIS movements in Norwegian waters, 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.
