CLIPPER EXPLORER 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 46,668 gross tonnage it is larger than 68% of the other 525 gas carriers with a recorded tonnage. It is one of 38 gas carriers here under the Norway flag, 5.5% of the 688 on the register. The same builder is recorded for 461 other vessels here, 17 of them gas carriers. Its MRV returns name it WEISSHORN EXPLORER for 2023 and CLIPPER EXPLORER for 2025. The reported port of registry changed: Majuro (2023), then Stavanger (2025).

Its 4,384 t of CO₂ for 2025 is 27% below the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 330.1 kg CO₂, 29% above the type median of 256.2 kg. It logged 895 hours at sea against a median of 1,943 hours for its type that year. 1.6% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Its efficiency percentile within the type was 12 in both 2023 and 2025. Of the 2 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 37 of 292 qualifying gas carriers by EEOI, at the 12th percentile. The dashed line is the type median, 27.9; this vessel reported 14.4.

EEOI divides emissions by transport work, which for this vessel and year was 304,840,751 tonne-miles over 13,280 nautical miles.

Reported CO₂ by year

2023: 4,886 t20234,8862025: 4,384 t20254,384

Reported CO₂ in 2025 was 10.3% lower than in 2023, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.

From 2023 to 2025, emissions fell 10.3% while distance sailed rose 6.2%and CO₂ per nautical mile fell 15.5%.That points mainly to how efficiently it sailed, rather than the other.
