SILVER ROTTERDAM 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 29,553 gross tonnage it is larger than 76% 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 ROTTERDAM for 2018–2022 and TORM DORIS for 2025. The reported port of registry changed: Panama (2018–2022), then HELLERUP (2025).
Its 2,774 t of CO₂ for 2025 is 50% 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 207.5 kg CO₂, 17% below the type median of 250.2 kg. It logged 1,349 hours at sea against a median of 2,106 hours for its type that year. 5.1% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 5 years with reported emissions, the highest was 2020 (10,699 t) and the lowest 2021 (2,017 t). Its efficiency percentile within the type went from 43 in 2018 to 9 in 2025 (lower is more efficient). Of the 7 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 128 of 1,348 qualifying chemical tankers by EEOI, at the 9th 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 352,035,533 tonne-miles over 13,368 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 6.1% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2023, 2024, so the series has gaps.
From 2022 to 2025, emissions rose 3.1% while distance sailed rose 42.6%and CO₂ per nautical mile fell 27.7%.That points mainly to how much the vessel sailed, rather than the other.
