NAVIGATOR VEGA against its type

Built in 2019, it is 6 years newer than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 19,205 gross tonnage it is smaller than 57% of the other 525 gas carriers with a recorded tonnage. It is one of 14 gas carriers here under the Hong Kong flag, 2.0% of the 688 on the register. Its MRV returns name it PACIFIC MERCURY for 2019–2022 and NAVIGATOR VEGA for 2023–2025. The reported port of registry changed: Hong Kong (2019–2022), then Monrovia (2023).

Its 2,741 t of CO₂ for 2025 is 54% below the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 235.4 kg CO₂, close to the type median of 256.2 kg. It logged 988 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%. Across 5 years with reported emissions, the highest was 2019 (10,023 t) and the lowest 2022 (2,185 t). Its efficiency percentile within the type went from 29 in 2019 to 68 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 198 of 292 qualifying gas carriers by EEOI, at the 68th percentile. The dashed line is the type median, 27.9; this vessel reported 44.2.

EEOI divides emissions by transport work, which for this vessel and year was 61,995,929 tonne-miles over 11,647 nautical miles.

Reported CO₂ in 2025 was 72.6% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2024, so the series has gaps.

From 2023 to 2025, emissions fell 3.4% while distance sailed fell 3.0%and CO₂ per nautical mile fell 0.4%.That points mainly to how much the vessel sailed, rather than the other.

Sources and how to read this

This page draws on 5 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.
