SLOMAN HERMES against its type

Built in 2012, it is 2 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 11,298 gross tonnage it is smaller than 79% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 7 chemical tankers here under the Antigua and Barbuda flag, 0.3% of the 2,344 on the register. The reported port of registry changed: Valletta (2018–2020), then St. John's (2023–2025).

Its 8,309 t of CO₂ for 2025 is 1.5 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 292.9 kg CO₂, 17% above the type median of 250.2 kg. It logged 2,916 hours at sea against a median of 2,109 hours for its type that year. 14.4% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2018 (9,085 t) and the lowest 2019 (6,722 t). Its efficiency percentile within the type went from 80 in 2018 to 90 in 2025 (lower is more efficient). Of the 4 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 1,217 of 1,348 qualifying chemical tankers by EEOI, at the 90th percentile. The dashed line is the type median, 14.4; this vessel reported 37.3.

EEOI divides emissions by transport work, which for this vessel and year was 222,636,388 tonne-miles over 28,372 nautical miles.

Reported CO₂ in 2025 was 8.5% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, so the series has gaps.

From 2024 to 2025, emissions rose 4.5% while distance sailed fell 19.9%and CO₂ per nautical mile rose 30.5%.That points mainly to how efficiently it sailed, rather than the other.

Sources and how to read this

This page draws on 6 MRV reporting years, an efficiency ranking and 4 of 5 vessel particulars. Not found in the sources for this vessel: AIS movements in Norwegian waters, a name history, 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.
