CSK VANGUARD against its type
Built in 2016, it is 6 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 63,497 gross tonnage it is larger than 65% of the other 2,841 oil tankers with a recorded tonnage. It is one of 237 oil tankers here under the Singapore flag, 6.7% of the 3,548 on the register. The same builder is recorded for 90 other vessels here, 10 of them oil tankers. The returns for 2023–2025 all give Singapore as port of registry.
Its 21,504 t of CO₂ for 2025 is 2.7 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 472.8 kg CO₂, 17% above the type median of 403.2 kg. It logged 4,567 hours at sea against a median of 2,030 hours for its type that year. 15.9% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 3 years with reported emissions, the highest was 2025 (21,504 t) and the lowest 2023 (8,897 t). Its efficiency percentile within the type went from 42 in 2023 to 63 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2025
Position 915 of 1,448 qualifying oil tankers by EEOI, at the 63rd percentile. The dashed line is the type median, 7.5; this vessel reported 8.6.
EEOI divides emissions by transport work, which for this vessel and year was 2,758,627,474 tonne-miles over 50,772 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 141.7% higher than in 2023, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 8.4% while distance sailed rose 21.4%and CO₂ per nautical mile fell 0.3%.That points mainly to how much the vessel sailed, rather than the other.
