DURGA against its type

Built in 2003, it is 7 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 23,235 gross tonnage it is smaller than 91% of the other 2,841 oil tankers with a recorded tonnage. It is the only oil tanker on this register under the Tuvalu flag. The same builder is recorded for 983 other vessels here, 270 of them oil tankers. Its MRV returns name it SEAMERCURY for 2018–2021, NAV DURGA for 2023–2024 and DURGA for 2025. The reported port of registry changed: VALLETTA (2018–2021), then Mumbai (2023–2024), then Funafuti (2025).

Its 9,808 t of CO₂ for 2025 is 24% above the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 426.0 kg CO₂, close to the type median of 403.2 kg. It logged 2,000 hours at sea against a median of 2,030 hours for its type that year. 17.4% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2019 (15,915 t) and the lowest 2024 (4,491 t). Its efficiency percentile within the type went from 91 in 2018 to 96 in 2025 (lower is more efficient).

Efficiency against its own type2025

Position 1,391 of 1,448 qualifying oil tankers by EEOI, at the 96th percentile. The dashed line is the type median, 7.5; this vessel reported 26.5.

0255075100more efficientless efficientThis vessel: 96th percentile, EEOI 26.5

EEOI divides emissions by transport work, which for this vessel and year was 370,096,226 tonne-miles over 23,022 nautical miles.

Reported CO₂ in 2025 was 84.0% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.

From 2024 to 2025, emissions rose 118.4% and CO₂ per nautical mile fell 32.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
