DART against its type

Built in 2015, it is 5 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,534 gross tonnage it is larger than 76% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. Its MRV returns name it MARLIN AMETHYST for 2018–2022 and DART for 2023–2025. The returns for 2021–2025 all give MAJURO as port of registry.

Its 2,054 t of CO₂ for 2023 is 62% below the median of 5,393 t among the 1,411 chemical tankers on this register that reported for 2023. Per nautical mile it emitted 308.5 kg CO₂, 20% above the type median of 258.0 kg. It logged 572 hours at sea against a median of 1,919 hours for its type that year. 9.4% of its 2023 emissions were at berth; the median for chemical tankers was 8.2%. Across 6 years with reported emissions, the highest was 2018 (8,366 t) and the lowest 2023 (2,054 t). Its efficiency percentile within the type went from 12 in 2018 to 32 in 2023 (lower is more efficient).

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

Efficiency against its own type2023

Position 399 of 1,230 qualifying chemical tankers by EEOI, at the 32nd percentile. The dashed line is the type median, 15.6; this vessel reported 12.7.

EEOI divides emissions by transport work, which for this vessel and year was 161,618,411 tonne-miles over 6,658 nautical miles.

Reported CO₂ by year

2018: 8,366 t20188,3662019: 3,289 t20192020: 6,052 t20202021: 4,335 t20212022: 4,946 t20222023: 2,054 t20232,054

Reported CO₂ in 2023 was 75.4% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.

From 2022 to 2023, emissions fell 58.5% while distance sailed fell 67.2%and CO₂ per nautical mile rose 26.6%.That points mainly to how much the vessel sailed, rather than the other.

Sources and how to read this

This page draws on 7 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.
