BASILISK against its type

Built in 2013, it is 6 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 14,859 gross tonnage it is larger than 72% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 381 general cargo ships here under the Antigua and Barbuda flag, 12.4% of the 3,081 on the register. Its MRV returns name it THORCO BASILISK for 2018–2021, BASILISK for 2022–2023 and BBC RHINE for 2024–2025. The reported port of registry changed: Basel (2020–2021), then MONROVIA (2022–2023), then St. John's (2024–2025).

Its 3,511 t of CO₂ for 2025 is 25% above the median of 2,820 t among the 2,469 general cargo ships on this register that reported for 2025. Per nautical mile it emitted 229.7 kg CO₂, 1.9 times the type median of 122.2 kg. It logged 1,204 hours at sea against a median of 3,044 hours for its type that year. 4.7% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 6 years with reported emissions, the highest was 2018 (6,887 t) and the lowest 2023 (3,109 t). Of the 8 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 49.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, so the series has gaps.

From 2024 to 2025, emissions fell 25.0% and CO₂ per nautical mile fell 0.4%.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 7 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.
