TESSA KOSAN against its type
Built in 1999, it is 14 years older than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 5,103 gross tonnage it is smaller than 100% of the other 525 gas carriers with a recorded tonnage. It is the only gas carrier on this register under the Malaysia flag. The same builder is recorded for 761 other vessels here, 100 of them gas carriers. The reported port of registry changed: Hellerup (2019–2020), then Valletta (2021–2022).
Its 6,454 t of CO₂ for 2022 is close to the median of 6,608 t among the 355 gas carriers on this register that reported for 2022. Per nautical mile it emitted 171.5 kg CO₂, 39% below the type median of 279.0 kg. It logged 3,441 hours at sea against a median of 1,992 hours for its type that year. 7.2% of its 2022 emissions were at berth; the median for gas carriers was 5.7%. Across 5 years with reported emissions, the highest was 2021 (12,221 t) and the lowest 2022 (6,454 t). Its efficiency percentile within the type went from 81 in 2018 to 89 in 2022 (lower is more efficient). The one sister ship listed below with a 2022 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2022
Position 282 of 316 qualifying gas carriers by EEOI, at the 89th percentile. The dashed line is the type median, 38.5; this vessel reported 109.4.
EEOI divides emissions by transport work, which for this vessel and year was 59,009,783 tonne-miles over 37,639 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 41.4% lower than in 2018, for EU/EEA voyages only.
From 2021 to 2022, emissions fell 47.2% while distance sailed fell 37.7%and CO₂ per nautical mile fell 15.2%.That points mainly to how much the vessel sailed, rather than the other.
