IVORY RAY against its type
Built in 2011, it is 1 year newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 11,987 gross tonnage it is smaller than 70% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 15 chemical tankers here under the South Korea flag, 0.6% 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 IVORY RAY for 2018–2023 and SH FREESIA for 2024–2025. The reported port of registry changed: Monrovia (2018–2023), then JEJU (2024–2025).
Its 7,420 t of CO₂ for 2025 is 34% above the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 206.3 kg CO₂, 18% below the type median of 250.2 kg. It logged 3,298 hours at sea against a median of 2,109 hours for its type that year. 5.4% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2018 (10,480 t) and the lowest 2021 (3,966 t). Its efficiency percentile within the type went from 45 in 2018 to 74 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,006 of 1,348 qualifying chemical tankers by EEOI, at the 74th percentile. The dashed line is the type median, 14.4; this vessel reported 22.9.
EEOI divides emissions by transport work, which for this vessel and year was 324,713,348 tonne-miles over 35,966 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 29.2% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 5.2% while distance sailed rose 11.5%and CO₂ per nautical mile fell 5.7%.That points mainly to how much the vessel sailed, rather than the other.
