SELENA against its type

It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. Its MRV returns name it SELENA for 2018–2024 and ORINOCCO for 2025. The reported port of registry changed: Antwerp (2018–2020), then Monrovia (2021), then Madeira (2024), then MONROVIA , LIBERIA (2025).

Its 1,720 t of CO₂ for 2025 is 78% below the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 415.2 kg CO₂, close to the type median of 403.2 kg. It logged 392 hours at sea against a median of 2,030 hours for its type that year. 9.0% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 5 years with reported emissions, the highest was 2020 (17,368 t) and the lowest 2025 (1,720 t). Its efficiency percentile within the type went from 49 in 2018 to 17 in 2021 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 67.4% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2022, 2023, so the series has gaps.

From 2021 to 2025, emissions fell 60.9% and CO₂ per nautical mile rose 14.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

Sources and how to read this

This page draws on 6 MRV reporting years, 2 of 5 vessel particulars and a name history. Not found in the sources for this vessel: an efficiency ranking, 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.
