LONE STAR against its type

Built in 2012, it is 5 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 24,212 gross tonnage it is larger than 91% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 216 general cargo ships here under the Liberia flag, 7.0% of the 3,081 on the register. Its MRV returns name it LONE STAR for 2018–2020 and NORDIC OSLO for 2021–2025. The reported port of registry changed: Majuro (2018–2020), then Monrovia (2021–2025).

Its 4,071 t of CO₂ for 2025 is 44% above the median of 2,820 t among the 2,469 general cargo ships on this register that reported for 2025. Per nautical mile it emitted 234.8 kg CO₂, 1.9 times the type median of 122.2 kg. It logged 1,686 hours at sea against a median of 3,044 hours for its type that year. 7.4% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 8 years with reported emissions, the highest was 2023 (5,618 t) and the lowest 2021 (1,599 t). Its efficiency percentile within the type went from 83 in 2018 to 93 in 2022 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2022

Position 3,438 of 3,692 qualifying bulk carriers by EEOI, at the 93rd percentile. The dashed line is the type median, 8.4; this vessel reported 16.2.

Reported CO₂ in 2025 was 20.4% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 23.1% and CO₂ per nautical mile fell 4.3%.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 8 MRV reporting years, an efficiency ranking, 4 of 5 vessel particulars, a name history and a licensed photograph. Not found in the sources for this vessel: AIS movements in Norwegian waters, 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.
