MAISAN against its type

Built in 2005, it is 5 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 42,661 gross tonnage it is smaller than 61% 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. The same builder is recorded for 96 other vessels here, 19 of them oil tankers.

Its 10,925 t of CO₂ for 2022 is 1.5 times the median of 7,189 t among the 1,939 oil tankers on this register that reported for 2022. Per nautical mile it emitted 422.7 kg CO₂, close to the type median of 415.9 kg. It logged 2,070 hours at sea against a median of 1,731 hours for its type that year. 2.8% of its 2022 emissions were at berth; the median for oil tankers was 9.1%. Across 3 years with reported emissions, the highest was 2022 (10,925 t) and the lowest 2019 (2,567 t). Its efficiency percentile within the type went from 75 in 2018 to 84 in 2022 (lower is more efficient). The one sister ship listed below with a 2022 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2022

Position 1,487 of 1,771 qualifying oil tankers by EEOI, at the 84th percentile. The dashed line is the type median, 8.0; this vessel reported 14.3.

0255075100more efficientless efficientThis vessel: 84th percentile, EEOI 14.3

EEOI divides emissions by transport work, which for this vessel and year was 763,479,385 tonne-miles over 25,848 nautical miles.

Reported CO₂ by year

2018: 8,092 t20188,0922019: 2,567 t20192022: 10,925 t202210,925

Reported CO₂ in 2022 was 35.0% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, so the series has gaps.

From 2019 to 2022, emissions rose 325.5% while distance sailed rose 272.8%and CO₂ per nautical mile rose 14.2%.That points mainly to how much the vessel sailed, rather than the other.
