NAVIG8 ESTELLE against its type
It is one of 205 chemical tankers here under the Singapore flag, 8.7% of the 2,344 on the register. The reported port of registry changed: Monrovia (2024), then Singapore (2025).
Its 5,083 t of CO₂ for 2025 is close to the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 323.2 kg CO₂, 29% above the type median of 250.2 kg. It logged 1,271 hours at sea against a median of 2,109 hours for its type that year. 6.4% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Its efficiency percentile within the type went from 19 in 2024 to 20 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.
