TAHOE SPIRIT against its type

Built in 2010, it is the same age as the median oil tanker on this register (build year 2010, 2,896 vessels with a known build year). At 83,545 gross tonnage it is larger than 81% of the other 2,841 oil tankers with a recorded tonnage. It is one of 180 oil tankers here under the Bahamas flag, 5.1% of the 3,548 on the register. The same builder is recorded for 34 other vessels here, 20 of them oil tankers. The returns for 2018–2025 all give Nassau as port of registry.

Its 8,417 t of CO₂ for 2025 is close to the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 480.6 kg CO₂, 19% above the type median of 403.2 kg. It logged 1,633 hours at sea against a median of 2,030 hours for its type that year. 3.7% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2023 (22,945 t) and the lowest 2018 (8,319 t). Its efficiency percentile within the type went from 68 in 2018 to 28 in 2025 (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.

Efficiency against its own type2025

Position 405 of 1,448 qualifying oil tankers by EEOI, at the 28th percentile. The dashed line is the type median, 7.5; this vessel reported 5.8.

Reported CO₂ in 2025 was 1.2% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.

From 2024 to 2025, emissions fell 37.1% while distance sailed fell 45.9%and CO₂ per nautical mile rose 16.2%.That points mainly to how much the vessel sailed, rather than the other.
