SITEAM LEADER against its type
Built in 2009, it is 1 year older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 26,794 gross tonnage it is larger than 63% 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. Its MRV returns name it SITEAM LEADER for 2018, TEAM LEADER for 2019–2020 and TORM LEADER for 2021–2025. The reported port of registry changed: Hamilton (2018–2020), then MARSTAL (2021–2025).
Its 10,710 t of CO₂ for 2025 is 1.9 times the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 349.1 kg CO₂, 40% above the type median of 250.2 kg. It logged 2,664 hours at sea against a median of 2,109 hours for its type that year. 6.9% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2019 (12,970 t) and the lowest 2021 (2,137 t). Its efficiency percentile within the type went from 17 in 2018 to 26 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 353 of 1,348 qualifying chemical tankers by EEOI, at the 26th percentile. The dashed line is the type median, 14.4; this vessel reported 10.4.
EEOI divides emissions by transport work, which for this vessel and year was 1,031,815,992 tonne-miles over 30,682 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 258.6% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 195.8% while distance sailed rose 125.9%and CO₂ per nautical mile rose 30.9%.That points mainly to how much the vessel sailed, rather than the other.
