POLARSTERN against its type

Built in 1982, it is 27 years older than the median vessel in the other ship types category on this register, which was built in 2009 (451 vessels with a known build year). At 12,614 gross tonnage it is larger than 58% of the other 436 vessels in the other ship types category with a recorded tonnage. It is one of 5 vessels in the other ship types category here under the Germany flag, 1.0% of the 499 on the register. The same builder is recorded for 32 other vessels here.

Its 15,027 t of CO₂ for 2018 is 2.4 times the median of 6,200 t among the 222 vessels in the other ship types category on this register that reported for 2018. Per nautical mile it emitted 497.5 kg CO₂, 2.0 times the type median of 245.6 kg. It logged 4,407 hours at sea against a median of 2,728 hours for its type that year. 2.6% of its 2018 emissions were at berth; the median for vessels in the other ship types category was 3.6%. The one comparable vessel listed below with a 2018 return reported a lower CO₂ per nautical mile.

Sources and how to read this

This page draws on 1 MRV reporting year, 5 of 5 vessel particulars, AIS movements in Norwegian waters and a licensed photograph. Not found in the sources for this vessel: an efficiency ranking, 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.
