MKK II against its type
Built in 1998, it is 14 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 13,965 gross tonnage it is smaller than 98% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 43 bulk carriers here under the Saint Kitts and Nevis flag, 0.5% of the 8,138 on the register. The same builder is recorded for 24 other vessels here, 16 of them bulk carriers. Its MRV returns name it TZAREVETZ for 2018–2019, TZAREVICH for 2020–2022 and MKK II for 2023–2025. The reported port of registry changed: Valletta (2018–2022), then Basseterre (2023–2025).
Its 1,373 t of CO₂ for 2025 is 58% 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 160.0 kg CO₂, 39% below the type median of 260.7 kg. It logged 782 hours at sea against a median of 1,200 hours for its type that year. 7.5% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 8 years with reported emissions, the highest was 2021 (7,805 t) and the lowest 2025 (1,373 t). Its efficiency percentile within the type went from 0 in 2018 to 97 in 2024 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 69.1% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 18.5% and CO₂ per nautical mile fell 21.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

This page draws on 8 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.
