NAVIGARE PARS against its type

Built in 2012, it is 2 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,840 gross tonnage it is larger than 85% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 218 chemical tankers here under the Malta flag, 9.3% of the 2,344 on the register. Its MRV returns name it NAVIGARE PARS for 2018–2022 and RED DIAMOND for 2023–2025. The reported port of registry changed: Skovshoved (2018–2022), then Valletta (2023–2025).

Its 16,270 t of CO₂ for 2025 is 2.9 times the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 421.3 kg CO₂, 1.7 times the type median of 250.2 kg. It logged 4,064 hours at sea against a median of 2,106 hours for its type that year. 13.2% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2025 (16,270 t) and the lowest 2020 (2,324 t). Its efficiency percentile within the type went from 21 in 2018 to 76 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,023 of 1,348 qualifying chemical tankers by EEOI, at the 76th percentile. The dashed line is the type median, 14.4; this vessel reported 23.7.

0255075100more efficientless efficientThis vessel: 76th percentile, EEOI 23.7

EEOI divides emissions by transport work, which for this vessel and year was 686,480,591 tonne-miles over 38,615 nautical miles.

Reported CO₂ in 2025 was 136.5% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 11.3% while distance sailed rose 2.1%and CO₂ per nautical mile rose 9.0%.That points mainly to how efficiently it sailed, rather than the other.

Sources and how to read this

This page draws on 8 MRV reporting years, an efficiency ranking, 4 of 5 vessel particulars and a name history. Not found in the sources for this vessel: 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.
