MARLEN against its type

Built in 2009, it is 1 year older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 30,174 gross tonnage it is larger than 93% 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 160 other vessels here, 8 of them chemical tankers. The returns for 2022–2025 all give Monrovia as port of registry.

Its 1,852 t of CO₂ for 2024 is 68% below the median of 5,830 t among the 1,451 chemical tankers on this register that reported for 2024. Per nautical mile it emitted 280.4 kg CO₂, 11% above the type median of 253.5 kg. It logged 756 hours at sea against a median of 2,177 hours for its type that year. 8.6% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%.

No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Reported CO₂ by year

2022: 2,294 t20222,2942024: 1,852 t20241,852

Reported CO₂ in 2024 was 19.3% lower than in 2022, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.

From 2022 to 2024, emissions fell 19.3% and CO₂ per nautical mile fell 54.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

Sources and how to read this

This page draws on 3 MRV reporting years and 5 of 5 vessel particulars. Not found in the sources for this vessel: an efficiency ranking, AIS movements in Norwegian waters, a name history, 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.
