BW AMAZON against its type

Built in 2006, it is 4 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 43,797 gross tonnage it is smaller than 59% 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 146 other vessels here, 55 of them oil tankers. Its MRV returns name it BW AMAZON for 2018–2020 and KRITI STATE for 2021–2025. The reported port of registry changed: Singapore (2018–2020), then Monrovia (2021–2025).

Its 5,638 t of CO₂ for 2025 is 29% below the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 401.6 kg CO₂, close to the type median of 403.2 kg. It logged 1,254 hours at sea against a median of 2,030 hours for its type that year. 5.9% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2023 (9,442 t) and the lowest 2018 (2,818 t). Its efficiency percentile within the type went from 47 in 2018 to 73 in 2025 (lower is more efficient). Of the 3 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 1,063 of 1,448 qualifying oil tankers by EEOI, at the 73rd percentile. The dashed line is the type median, 7.5; this vessel reported 10.3.

Reported CO₂ in 2025 was 100.1% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 78.8% and CO₂ per nautical mile fell 27.9%.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, an efficiency ranking, 5 of 5 vessel particulars and a name history. Not found in the sources for this vessel: 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.
