CRIMSON PEARL against its type
Built in 2017, it is 7 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 30,523 gross tonnage it is smaller than 69% of the other 2,841 oil tankers with a recorded tonnage. 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 CRIMSON PEARL for 2019–2023 and HIGH MARINER for 2024–2025. The reported port of registry changed: PANAMA (2019–2023), then Monrovia (2024–2025).
Its 4,094 t of CO₂ for 2025 is 48% 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 304.5 kg CO₂, 24% below the type median of 403.2 kg. It logged 1,266 hours at sea against a median of 2,030 hours for its type that year. 10.3% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 6 years with reported emissions, the highest was 2020 (7,185 t) and the lowest 2024 (1,201 t). Its efficiency percentile within the type went from 42 in 2019 to 83 in 2025 (lower is more efficient). Of the 3 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,196 of 1,448 qualifying oil tankers by EEOI, at the 83rd percentile. The dashed line is the type median, 7.5; this vessel reported 12.9.
EEOI divides emissions by transport work, which for this vessel and year was 316,850,619 tonne-miles over 13,445 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 92.8% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2024 to 2025, emissions rose 240.8% and CO₂ per nautical mile rose 33.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
