ROSE I against its type
Built in 2007, it is 3 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 23,248 gross tonnage it is smaller than 90% 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. The same builder is recorded for 983 other vessels here, 270 of them oil tankers. Its MRV returns name it STAR I for 2018–2021 and ROSE I for 2022–2025. The reported port of registry changed: Majuro, Marshall Islands (2018–2021), then MONROVIA (2022–2025).
Its 1,033 t of CO₂ for 2025 is 87% 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 279.6 kg CO₂, 31% below the type median of 403.2 kg. It logged 328 hours at sea against a median of 2,030 hours for its type that year. 8.5% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2019 (14,652 t) and the lowest 2025 (1,033 t). Its efficiency percentile within the type went from 85 in 2018 to 91 in 2022 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 89.6% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions fell 55.8% and CO₂ per nautical mile rose 6.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

This page draws on 7 MRV reporting years, 5 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.
