BOLKAR against its type

Built in 2005, it is 7 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 24,109 gross tonnage it is smaller than 79% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 1,601 bulk carriers here under the Panama flag, 19.7% of the 8,138 on the register. Its MRV returns name it MAZURY for 2018–2024 and BOLKAR for 2025. The reported port of registry changed: Nassau (2018–2024), then Panama (2025).

Its 488 t of CO₂ for 2025 is 85% below the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 208.3 kg CO₂, 20% below the type median of 260.7 kg. It logged 208 hours at sea against a median of 1,200 hours for its type that year. 6.5% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 8 years with reported emissions, the highest was 2018 (8,266 t) and the lowest 2025 (488 t). Its efficiency percentile within the type went from 67 in 2018 to 72 in 2024 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 94.1% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 85.7% and CO₂ per nautical mile fell 13.7%.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, 4 of 5 vessel particulars, a name history and a licensed photograph. Not found in the sources for this vessel: an efficiency ranking, 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.
