TERN SEA against its type

Built in 2016, it is 6 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 11,374 gross tonnage it is smaller than 79% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 93 chemical tankers here under the Denmark flag, 4.0% of the 2,344 on the register. The same builder is recorded for 40 other vessels here, 32 of them chemical tankers. Terntank is linked to 9 vessels on this register. The returns for 2018–2025 all give Skagen as port of registry.

Its 9,534 t of CO₂ for 2025 is 1.7 times the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 155.2 kg CO₂, 38% below the type median of 250.2 kg. It logged 5,484 hours at sea against a median of 2,109 hours for its type that year. 10.2% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2018 (11,404 t) and the lowest 2023 (9,016 t). Its efficiency percentile within the type went from 77 in 2018 to 72 in 2025 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Sources and how to read this

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