BLUE TRADER against its type

Built in 2005, it is 5 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 23,298 gross tonnage it is larger than 52% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 259 chemical tankers here under the Panama flag, 11.0% of the 2,344 on the register. The same builder is recorded for 983 other vessels here, 330 of them chemical tankers. Its MRV returns name it EMERALD STARS for 2018–2020, BLUE TRADER for 2021–2022 and HAZAR for 2024–2025. The reported port of registry changed: Valletta (2018), then Madeira (2019–2021), then Majuro (2022), then Panama (2024–2025).

Its 6,351 t of CO₂ for 2025 is 15% above the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 385.1 kg CO₂, 1.5 times the type median of 250.2 kg. It logged 3,410 hours at sea against a median of 2,106 hours for its type that year. 16.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2019 (17,542 t) and the lowest 2024 (2,506 t). Its efficiency percentile within the type went from 96 in 2018 to 75 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,010 of 1,348 qualifying chemical tankers by EEOI, at the 75th percentile. The dashed line is the type median, 14.4; this vessel reported 23.0.

0255075100more efficientless efficientThis vessel: 75th percentile, EEOI 23.0

EEOI divides emissions by transport work, which for this vessel and year was 275,644,965 tonne-miles over 16,492 nautical miles.

Reported CO₂ in 2025 was 63.4% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.

From 2024 to 2025, emissions rose 153.4% and CO₂ per nautical mile rose 6.4%.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 7 MRV reporting years, an efficiency ranking, 5 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.
