NISSOS HERACLEA against its type

Built in 2015, it is 5 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 62,832 gross tonnage it is larger than 62% of the other 2,841 oil tankers with a recorded tonnage. It is one of 17 oil tankers here under the France flag, 0.5% of the 3,548 on the register. The same builder is recorded for 761 other vessels here, 193 of them oil tankers. Its MRV returns name it NISSOS HERACLEA for 2018–2020 and TORM KIARA for 2021–2025. The reported port of registry changed: Piraeus (2018–2020), then ROENNE (2021–2022), then Rønne (2023), then Roenne (2024), then RØNNE (2025).

Its 7,280 t of CO₂ for 2025 is close to the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 382.3 kg CO₂, close to the type median of 403.2 kg. It logged 1,804 hours at sea against a median of 2,030 hours for its type that year. 13.6% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2022 (12,926 t) and the lowest 2024 (330 t). Its efficiency percentile within the type went from 21 in 2018 to 37 in 2025 (lower is more efficient). Of the 5 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 543 of 1,448 qualifying oil tankers by EEOI, at the 37th percentile. The dashed line is the type median, 7.5; this vessel reported 6.6.

0255075100more efficientless efficientThis vessel: 37th percentile, EEOI 6.6

EEOI divides emissions by transport work, which for this vessel and year was 1,109,763,720 tonne-miles over 19,043 nautical miles.

Reported CO₂ in 2025 was 1.7% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, so the series has gaps.

From 2024 to 2025, emissions rose 2,105.3% and CO₂ per nautical mile rose 25.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
