SILVER OAK against its type

Built in 2018, it is 11 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 23,232 gross tonnage it is larger than 87% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 51 general cargo ships here under the Singapore flag, 1.7% of the 3,081 on the register. The same builder is recorded for 80 other vessels here, 22 of them general cargo ships. Its MRV returns name it SILVER OAK for 2019–2021 and TATUNG for 2025. The reported port of registry changed: PANAMA (2019–2021), then Singapore (2025).

Its 1,788 t of CO₂ for 2025 is 37% below the median of 2,820 t among the 2,469 general cargo ships on this register that reported for 2025. Per nautical mile it emitted 184.8 kg CO₂, 1.5 times the type median of 122.2 kg. It logged 806 hours at sea against a median of 3,044 hours for its type that year. 11.6% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 4 years with reported emissions, the highest was 2020 (2,932 t) and the lowest 2019 (1,279 t). Its efficiency percentile within the type went from 25 in 2019 to 24 in 2021 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2021

Position 802 of 3,276 qualifying bulk carriers by EEOI, at the 24th percentile. The dashed line is the type median, 8.4; this vessel reported 6.5.

Reported CO₂ in 2025 was 39.8% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2022, 2023, 2024, so the series has gaps.

From 2021 to 2025, emissions fell 33.7% and CO₂ per nautical mile fell 10.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
