SILVER DOVER against its type
Built in 2015, it is 5 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,327 gross tonnage it is larger than 71% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 93 chemical tankers here under the Denmark flag, 4.0% of the 2,344 on the register. The same builder is recorded for 983 other vessels here, 330 of them chemical tankers. Its MRV returns name it SILVER DOVER for 2019–2021 and TORM DAGNY for 2024–2025. The reported port of registry changed: MAJURO (2019–2021), then Hellerup (2024–2025).
Its 1,596 t of CO₂ for 2025 is 71% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 274.2 kg CO₂, close to the type median of 250.2 kg. It logged 525 hours at sea against a median of 2,106 hours for its type that year. 2.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 5 years with reported emissions, the highest was 2024 (7,317 t) and the lowest 2025 (1,596 t). Its efficiency percentile within the type went from 20 in 2019 to 10 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 138 of 1,348 qualifying chemical tankers by EEOI, at the 10th percentile. The dashed line is the type median, 14.4; this vessel reported 7.9.
EEOI divides emissions by transport work, which for this vessel and year was 201,060,453 tonne-miles over 5,822 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 51.2% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions fell 78.2% while distance sailed fell 77.4%and CO₂ per nautical mile fell 3.4%.That points mainly to how much the vessel sailed, rather than the other.
