CONRAD OLDENDORFF against its type

Built in 2010, it is 2 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 51,239 gross tonnage it is larger than 85% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 1,603 bulk carriers here under the Marshall Islands flag, 19.7% of the 8,138 on the register. The same builder is recorded for 65 other vessels here, 44 of them bulk carriers. Its MRV returns name it CONRAD OLDENDORFF for 2020–2021 and JOHNY for 2024–2025. The reported port of registry changed: Monrovia (2020–2021), then Majuro (2024–2025).

Its 4,082 t of CO₂ for 2025 is 26% above the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 346.3 kg CO₂, 33% above the type median of 260.7 kg. It logged 1,066 hours at sea against a median of 1,200 hours for its type that year. 4.0% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 4 years with reported emissions, the highest was 2021 (9,943 t) and the lowest 2025 (4,082 t). Its efficiency percentile within the type went from 34 in 2020 to 90 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 2,919 of 3,241 qualifying bulk carriers by EEOI, at the 90th percentile. The dashed line is the type median, 7.6; this vessel reported 12.7.

EEOI divides emissions by transport work, which for this vessel and year was 320,412,088 tonne-miles over 11,788 nautical miles.

Reported CO₂ in 2025 was 22.3% lower than in 2020, for EU/EEA voyages only. No return is recorded for 2022, 2023, so the series has gaps.

From 2024 to 2025, emissions fell 32.3% while distance sailed fell 26.2%and CO₂ per nautical mile fell 8.3%.That points mainly to how much the vessel sailed, rather than the other.

Sources and how to read this

This page draws on 4 MRV reporting years, an efficiency ranking, 5 of 5 vessel particulars and a name history. Not found in the sources for this vessel: 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.
