GENUINE HERCULES against its type

Built in 2013, it is 3 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 19,899 gross tonnage it is smaller than 56% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. The same builder is recorded for 76 other vessels here, 58 of them chemical tankers. Its MRV returns name it GENUINE HERCULES for 2018–2020 and STOLT ORCA for 2022–2025. The reported port of registry changed: SINGAPORE (2018–2020), then Monrovia (2022–2025).

Its 2,829 t of CO₂ for 2025 is 49% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 252.4 kg CO₂, close to the type median of 250.2 kg. It logged 1,075 hours at sea against a median of 2,106 hours for its type that year. 1.3% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2023 (7,678 t) and the lowest 2025 (2,829 t). Its efficiency percentile within the type went from 46 in 2018 to 42 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 567 of 1,348 qualifying chemical tankers by EEOI, at the 42nd percentile. The dashed line is the type median, 14.4; this vessel reported 13.0.

EEOI divides emissions by transport work, which for this vessel and year was 217,779,061 tonne-miles over 11,206 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 42.5% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.

From 2024 to 2025, emissions fell 59.1% while distance sailed fell 56.7%and CO₂ per nautical mile fell 5.6%.That points mainly to how much the vessel sailed, rather than the other.

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.
