KALAMAS against its type
Built in 2011, it is 1 year newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 55,909 gross tonnage it is smaller than 57% of the other 2,841 oil tankers with a recorded tonnage. It is one of 793 oil tankers here under the Marshall Islands flag, 22.4% of the 3,548 on the register. Its MRV returns name it KALAMAS for 2018–2019 and P. YANBU for 2021–2023. The reported port of registry changed: Monrovia (2018–2019), then Majuro (2021–2023).
Its 1,752 t of CO₂ for 2023 is 77% below the median of 7,491 t among the 1,850 oil tankers on this register that reported for 2023. Per nautical mile it emitted 552.9 kg CO₂, 35% above the type median of 408.5 kg. It logged 425 hours at sea against a median of 1,807 hours for its type that year. 7.3% of its 2023 emissions were at berth; the median for oil tankers was 8.4%. Across 5 years with reported emissions, the highest was 2019 (8,080 t) and the lowest 2023 (1,752 t). Its efficiency percentile within the type went from 57 in 2018 to 89 in 2022 (lower is more efficient). The one comparable vessel listed below with a 2023 return reported a lower CO₂ per nautical mile.

Reported CO₂ by year
Reported CO₂ in 2023 was 69.1% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2022 to 2023, emissions fell 37.4% and CO₂ per nautical mile fell 55.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
