LONE against its type
Built in 2011, it is the same age as the median offshore vessel on this register (build year 2011, 410 vessels with a known build year). At 15,199 gross tonnage it is larger than 89% of the other 396 offshore vessels with a recorded tonnage. It is the only offshore vessel on this register under the Antigua and Barbuda flag. The same builder is recorded for 180 other vessels here. The returns for 2018–2025 all give St. John's as port of registry.
Its 16,306 t of CO₂ for 2025 is 4.0 times the median of 4,049 t among the 390 offshore vessels on this register that reported for 2025. Per nautical mile it emitted 923.4 kg CO₂, 2.7 times the type median of 348.3 kg. It logged 4,339 hours at sea against a median of 3,550 hours for its type that year. 7.0% of its 2025 emissions were at berth; the median for offshore vessels was 6.4%. Across 8 years with reported emissions, the highest was 2018 (16,548 t) and the lowest 2019 (4,835 t). Its efficiency percentile within the type went from 92 in 2023 to 66 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 8 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 22 of 33 qualifying other ship types (offshore)s by EEOI, at the 66th percentile. The dashed line is the type median, 1,142.7.
EEOI divides emissions by transport work, which for this vessel and year was 9,473,237 tonne-miles over 17,659 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 1.5% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 108.4% while distance sailed fell 13.0%and CO₂ per nautical mile rose 139.5%.That points mainly to how efficiently it sailed, rather than the other.
