DISCOVERY BAY against its type
Built in 2016, it is 4 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 32,746 gross tonnage it is smaller than 62% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 428 bulk carriers here under the Singapore flag, 5.3% of the 8,138 on the register. The same builder is recorded for 307 other vessels here, 48 of them bulk carriers. Pacific Basin Shipping Limited is linked to 14 vessels on this register. The reported port of registry changed: SINGAPORE (2018–2021), then Majuro (2024), then Singapore (2025).
Its 4,080 t of CO₂ for 2025 is 26% above the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 248.4 kg CO₂, close to the type median of 260.7 kg. It logged 2,134 hours at sea against a median of 1,200 hours for its type that year. 5.1% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 6 years with reported emissions, the highest was 2018 (8,423 t) and the lowest 2024 (1,213 t). Its efficiency percentile within the type went from 33 in 2018 to 18 in 2025 (lower is more efficient). Of the 4 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 597 of 3,241 qualifying bulk carriers by EEOI, at the 18th percentile. The dashed line is the type median, 7.6; this vessel reported 5.5.
Across the 14 ranked vessels operated by Pacific Basin Shipping Limited, the median percentile is 65. This vessel is more efficient than its own fleet median.
EEOI divides emissions by transport work, which for this vessel and year was 748,629,358 tonne-miles over 16,427 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 51.6% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions rose 236.3% while distance sailed rose 217.4%and CO₂ per nautical mile rose 6.0%.That points mainly to how much the vessel sailed, rather than the other.
