MURRAY STAR against its type

Built in 2011, it is 1 year newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 8,581 gross tonnage it is smaller than 84% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 218 chemical tankers here under the Malta flag, 9.3% of the 2,344 on the register. The returns for 2018–2025 all give Valletta as port of registry.

Its 8,055 t of CO₂ for 2025 is 46% 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 247.4 kg CO₂, close to the type median of 250.2 kg. It logged 3,777 hours at sea against a median of 2,109 hours for its type that year. 17.3% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2019 (8,949 t) and the lowest 2023 (5,423 t). Its efficiency percentile within the type went from 98 in 2018 to 97 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,308 of 1,348 qualifying chemical tankers by EEOI, at the 97th percentile. The dashed line is the type median, 14.4; this vessel reported 49.2.

Reported CO₂ in 2025 was 1.4% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 43.6% while distance sailed rose 53.2%and CO₂ per nautical mile fell 6.3%.That points mainly to how much the vessel sailed, rather than the other.

Sources and how to read this

This page draws on 8 MRV reporting years, an efficiency ranking, 4 of 5 vessel particulars, AIS movements in Norwegian waters and a licensed photograph. Not found in the sources for this vessel: a name history, 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.
