CROWN TOPAZ against its type

Built in 1999, it is 5 years newer than the median refrigerated cargo carrier on this register, which was built in 1994 (183 vessels with a known build year). At 10,527 gross tonnage it is larger than 60% of the other 178 refrigerated cargo carriers with a recorded tonnage. It is one of 96 refrigerated cargo carriers here under the Bahamas flag, 47.5% of the 202 on the register. The same builder is recorded for 114 other vessels here, 13 of them refrigerated cargo carriers. The returns for 2018–2025 all give Nassau as port of registry.

Its 6,196 t of CO₂ for 2025 is 19% above the median of 5,190 t among the 111 refrigerated cargo carriers on this register that reported for 2025. Per nautical mile it emitted 266.0 kg CO₂, close to the type median of 260.9 kg. It logged 1,415 hours at sea against a median of 1,731 hours for its type that year. 3.0% of its 2025 emissions were at berth; the median for refrigerated cargo carriers was 3.8%. Across 6 years with reported emissions, the highest was 2020 (13,698 t) and the lowest 2018 (3,801 t). Its efficiency percentile within the type went from 7 in 2018 to 55 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 53 of 95 qualifying refrigerated cargo carriers by EEOI, at the 55th percentile. The dashed line is the type median, 55.3; this vessel reported 56.6.

0255075100more efficientless efficientThis vessel: 55th percentile, EEOI 56.6

EEOI divides emissions by transport work, which for this vessel and year was 109,526,251 tonne-miles over 23,295 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 63.0% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.

From 2023 to 2025, emissions rose 53.8% while distance sailed rose 73.5%and CO₂ per nautical mile fell 11.3%.That points mainly to how much the vessel sailed, rather than the other.
