SAN SABA against its type

Built in 2012, it is 2 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 81,346 gross tonnage it is larger than 74% of the other 2,841 oil tankers with a recorded tonnage. It is one of 793 oil tankers here under the Marshall Islands flag, 22.4% of the 3,548 on the register. The same builder is recorded for 761 other vessels here, 193 of them oil tankers. Its MRV returns name it SAN SABA for 2018–2021 and SEAWAYS SAN SABA for 2022–2025. The returns for 2018–2025 all give Majuro as port of registry.

Its 23,089 t of CO₂ for 2025 is 2.9 times the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 494.6 kg CO₂, 23% above the type median of 403.2 kg. It logged 4,672 hours at sea against a median of 2,030 hours for its type that year. 6.4% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2024 (29,251 t) and the lowest 2022 (1,688 t). Its efficiency percentile within the type went from 16 in 2018 to 43 in 2024 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 71.0% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 21.1% and CO₂ per nautical mile rose 2.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

Sources and how to read this

This page draws on 8 MRV reporting years, 5 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.
