MYGAS against its type

Built in 2017, it is 4 years newer than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 13,549 gross tonnage it is smaller than 73% of the other 525 gas carriers with a recorded tonnage. It is one of 10 gas carriers here under the Antigua and Barbuda flag, 1.5% of the 688 on the register. The same builder is recorded for 96 other vessels here, 7 of them gas carriers. Its MRV returns name it MYGAS for 2018–2021, MYGAS (MYGAS) for 2022 and MYGAS for 2023–2025. The reported port of registry changed: Saint John's (2018–2021), then Saint John's (AG SJO) (2022), then Saint John's (2023–2025).

Its 12,994 t of CO₂ for 2025 is 2.2 times the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 269.5 kg CO₂, close to the type median of 256.2 kg. It logged 4,202 hours at sea against a median of 1,943 hours for its type that year. 6.6% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 8 years with reported emissions, the highest was 2021 (15,861 t) and the lowest 2023 (2,387 t). Its efficiency percentile within the type went from 54 in 2018 to 92 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 268 of 292 qualifying gas carriers by EEOI, at the 92nd percentile. The dashed line is the type median, 27.9; this vessel reported 101.1.

Reported CO₂ in 2025 was 15.5% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 344.5% while distance sailed rose 369.5%and CO₂ per nautical mile fell 5.3%.That points mainly to how much the vessel sailed, rather than the other.

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 name history. Not found in the sources for this vessel: 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.
