SHAMROCK JUPITER 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 11,726 gross tonnage it is smaller than 74% 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 52 other vessels here, 48 of them chemical tankers. The returns for 2021–2025 all give PANAMA as port of registry.

Its 7,297 t of CO₂ for 2025 is 32% 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 219.8 kg CO₂, 12% below the type median of 250.2 kg. It logged 2,794 hours at sea against a median of 2,109 hours for its type that year. 12.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 3 years with reported emissions, the highest was 2025 (7,297 t) and the lowest 2021 (1,510 t). Its efficiency percentile within the type went from 95 in 2024 to 67 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 906 of 1,348 qualifying chemical tankers by EEOI, at the 67th percentile. The dashed line is the type median, 14.4; this vessel reported 19.6.

0255075100more efficientless efficientThis vessel: 67th percentile, EEOI 19.6

EEOI divides emissions by transport work, which for this vessel and year was 371,348,092 tonne-miles over 33,204 nautical miles.

2021: 1,510 t20211,5102024: 3,411 t20242025: 7,297 t20257,297

Reported CO₂ in 2025 was 383.3% higher than in 2021, for EU/EEA voyages only. No return is recorded for 2022, 2023, so the series has gaps.

From 2024 to 2025, emissions rose 113.9% while distance sailed rose 258.7%and CO₂ per nautical mile fell 40.4%.That points mainly to how much the vessel sailed, rather than the other.
