NANTUCKET against its type

Built in 2014, it is 4 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 82,043 gross tonnage it is larger than 78% of the other 2,841 oil tankers with a recorded tonnage. It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. The same builder is recorded for 34 other vessels here, 20 of them oil tankers. The reported port of registry changed: Valletta (2018–2021), then Monrovia (2022–2025).

Its 13,493 t of CO₂ for 2025 is 1.7 times the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 489.5 kg CO₂, 21% above the type median of 403.2 kg. It logged 2,368 hours at sea against a median of 2,030 hours for its type that year. 10.4% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 6 years with reported emissions, the highest was 2024 (13,621 t) and the lowest 2021 (8,779 t). Its efficiency percentile within the type went from 24 in 2018 to 37 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 536 of 1,448 qualifying oil tankers by EEOI, at the 37th percentile. The dashed line is the type median, 7.5; this vessel reported 6.5.

0255075100more efficientless efficientThis vessel: 37th percentile, EEOI 6.5

EEOI divides emissions by transport work, which for this vessel and year was 2,066,332,312 tonne-miles over 27,563 nautical miles.

Reported CO₂ in 2025 was 27.9% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, so the series has gaps.

From 2024 to 2025, emissions fell 0.9% while distance sailed fell 10.9%and CO₂ per nautical mile rose 11.2%.
