HELGA ESSBERGER against its type

Built in 1999, it is 11 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 6,785 gross tonnage it is smaller than 92% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 71 chemical tankers here under the Portugal flag, 3.0% of the 2,344 on the register. The returns for 2018–2025 all give Madeira as port of registry.

Its 9,637 t of CO₂ for 2025 is 1.7 times the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 189.3 kg CO₂, 24% below the type median of 250.2 kg. It logged 4,683 hours at sea against a median of 2,109 hours for its type that year. 11.5% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2021 (11,702 t) and the lowest 2018 (6,901 t). Its efficiency percentile within the type was 98 in both 2018 and 2025. Of the 7 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,322 of 1,348 qualifying chemical tankers by EEOI, at the 98th percentile. The dashed line is the type median, 14.4; this vessel reported 53.1.

Reported CO₂ in 2025 was 39.6% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 3.5% while distance sailed rose 14.9%and CO₂ per nautical mile fell 9.9%.That points mainly to how much the vessel sailed, rather than the other.
