UML VALENTINA against its type
Built in 2010, it is 1 year newer than the median vessel in the other ship types category on this register, which was built in 2009 (451 vessels with a known build year). At 9,772 gross tonnage it is smaller than 51% of the other 436 vessels in the other ship types category with a recorded tonnage. It is one of 46 vessels in the other ship types category here under the Antigua and Barbuda flag, 9.2% of the 499 on the register. Its MRV returns name it ZEA MAHAWELI for 2018–2019 and UML VALENTINA for 2020–2025. The reported port of registry changed: Colombo (2018–2019), then St. John`s (2020–2022), then Saint John's (2024–2025).
Its 6,460 t of CO₂ for 2025 is 26% above the median of 5,122 t among the 335 vessels in the other ship types category on this register that reported for 2025. Per nautical mile it emitted 186.8 kg CO₂, 19% below the type median of 231.1 kg. It logged 2,411 hours at sea against a median of 2,231 hours for its type that year. 4.0% of its 2025 emissions were at berth; the median for vessels in the other ship types category was 3.9%. Across 7 years with reported emissions, the highest was 2019 (9,680 t) and the lowest 2022 (1,188 t). Of the 5 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 85.9% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions rose 268.3% and CO₂ per nautical mile rose 2.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

This page draws on 7 MRV reporting years, 4 of 5 vessel particulars and a name history. Not found in the sources for this vessel: an efficiency ranking, AIS movements in Norwegian waters, a licensed photograph, a sanctions listing and US port state inspections.
Empty means unreported, never zero. How EEOI, distance, percentiles and sister ships are handled is explained under reading a vessel page. Something wrong? See corrections.
