CAMDEN against its type

Built in 2008, it is 2 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 8,539 gross tonnage it is smaller than 85% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. Its MRV returns name it CAMDEN for 2018 and OWL 4 for 2021–2025. The returns for 2018–2025 all give Majuro as port of registry.

Its 2,912 t of CO₂ for 2025 is 47% below the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 244.2 kg CO₂, close to the type median of 250.2 kg. It logged 1,495 hours at sea against a median of 2,109 hours for its type that year. 23.2% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 5 years with reported emissions, the highest was 2018 (4,590 t) and the lowest 2024 (1,424 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

2018: 4,590 t20184,5902021: 1,735 t20212022: 1,760 t20222024: 1,424 t20242025: 2,912 t20252,912

Reported CO₂ in 2025 was 36.6% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2023, so the series has gaps.

From 2024 to 2025, emissions rose 104.4% and CO₂ per nautical mile rose 47.9%.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 5 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.
