SUMMER PLOEG against its type
Built in 2017, it is 7 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 12,082 gross tonnage it is smaller than 69% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 48 chemical tankers here under the Cayman Islands flag, 2.0% of the 2,344 on the register. The same builder is recorded for 52 other vessels here, 48 of them chemical tankers. Its MRV returns name it SUMMER PLOEG for 2018–2022 and SWAN ATLANTIC for 2023–2025. The returns for 2018–2025 all give George Town as port of registry.
Its 10,363 t of CO₂ for 2025 is 1.9 times the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 220.0 kg CO₂, 12% below the type median of 250.2 kg. It logged 4,133 hours at sea against a median of 2,106 hours for its type that year. 9.1% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2024 (11,640 t) and the lowest 2021 (1,181 t). Its efficiency percentile within the type went from 28 in 2018 to 81 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,089 of 1,348 qualifying chemical tankers by EEOI, at the 81st percentile. The dashed line is the type median, 14.4; this vessel reported 27.1.
EEOI divides emissions by transport work, which for this vessel and year was 381,990,416 tonne-miles over 47,108 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 172.1% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 11.0% while distance sailed fell 14.7%and CO₂ per nautical mile rose 4.4%.That points mainly to how much the vessel sailed, rather than the other.
