ADELHEID-S. against its type

Built in 2006, it is 2 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 35,581 gross tonnage it is smaller than 61% of the other 3,000 container ships with a recorded tonnage. It is one of 976 container ships here under the Liberia flag, 27.9% of the 3,495 on the register. The same builder is recorded for 133 other vessels here, 105 of them container ships. Its MRV returns name it ADELHEID-S. for 2018–2020 and BSG BONAIRE for 2024–2025. The reported port of registry changed: Saint John's (2018–2020), then Monrovia (2024–2025).

Its 24,298 t of CO₂ for 2025 is 49% above the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 367.0 kg CO₂, 33% below the type median of 545.6 kg. It logged 5,426 hours at sea against a median of 3,155 hours for its type that year. 4.0% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 5 years with reported emissions, the highest was 2018 (38,379 t) and the lowest 2025 (24,298 t). Its efficiency percentile within the type went from 69 in 2018 to 52 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 951 of 1,838 qualifying container ships by EEOI, at the 52nd percentile. The dashed line is the type median, 14.2; this vessel reported 14.8.

EEOI divides emissions by transport work, which for this vessel and year was 1,646,189,702 tonne-miles over 66,210 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 36.7% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2023, so the series has gaps.

From 2024 to 2025, emissions fell 3.2% while distance sailed rose 21.0%and CO₂ per nautical mile fell 20.0%.
