GH HELM against its type
Built in 2009, it is 3 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 94,008 gross tonnage it is larger than 96% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 3 bulk carriers here under the Bermuda flag, 0.0% of the 8,138 on the register. The same builder is recorded for 660 other vessels here, 60 of them bulk carriers. Its MRV returns name it NYMPHE for 2020–2022 and GH HELM for 2024–2025. The reported port of registry changed: Piraeus (2020–2022), then Hamilton (2024–2025).
Its 17,095 t of CO₂ for 2025 is 5.3 times the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 567.4 kg CO₂, 2.2 times the type median of 260.7 kg. It logged 3,054 hours at sea against a median of 1,200 hours for its type that year. 1.5% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 5 years with reported emissions, the highest was 2025 (17,095 t) and the lowest 2020 (3,330 t). Its efficiency percentile within the type went from 1 in 2020 to 6 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2025
Position 180 of 3,241 qualifying bulk carriers by EEOI, at the 6th percentile. The dashed line is the type median, 7.6; this vessel reported 4.1.
EEOI divides emissions by transport work, which for this vessel and year was 4,189,879,902 tonne-miles over 30,131 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 413.4% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions rose 198.3% while distance sailed rose 159.5%and CO₂ per nautical mile rose 15.0%.That points mainly to how much the vessel sailed, rather than the other.
