CTG ARGON against its type

Built in 2016, it is 6 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 17,139 gross tonnage it is smaller than 59% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. The same builder is recorded for 40 other vessels here, 32 of them chemical tankers. Its MRV returns name it CTG ARGON for 2018 and STOLT ARGON for 2021–2025. The reported port of registry changed: Majuro (2018), then Monrovia (2021–2025).

Its 6,646 t of CO₂ for 2025 is 20% above the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 219.4 kg CO₂, 12% below the type median of 250.2 kg. It logged 2,492 hours at sea against a median of 2,109 hours for its type that year. 4.7% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2018 (13,961 t) and the lowest 2022 (3,461 t). Its efficiency percentile within the type went from 40 in 2018 to 52 in 2025 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 8 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 695 of 1,348 qualifying chemical tankers by EEOI, at the 52nd percentile. The dashed line is the type median, 14.4; this vessel reported 14.8.

0255075100more efficientless efficientThis vessel: 52nd percentile, EEOI 14.8

EEOI divides emissions by transport work, which for this vessel and year was 449,063,514 tonne-miles over 30,298 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 52.4% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, so the series has gaps.

From 2024 to 2025, emissions fell 10.5% while distance sailed fell 14.7%and CO₂ per nautical mile rose 4.9%.That points mainly to how much the vessel sailed, rather than the other.
