Annual Efficiency Ratio development (AER)

35% reduction since 2009

The average AER decreased from 10.8 to 10.5 in 2022 due to sale of the oldest ethylene vessel. We expect a big AER improvement in 2023 with full effect in 2024. This is due to EEXI certifications and upgrades on the H-Class fleet, LGC fleet and two VLGC vessels.

The LGC fleet increased due to port inefficiencies for some vessels. Six of the LGC vessels are in the last year before dry docking which decreases their performance.

The VLGC fleet is almost flat, with two dry dockings in 2022 and two more to come in 2023.

Energy Efficiency Operational Indicator (EEOI

47% reduction since 2009

Selling of the oldest ethylene vessel improved the EEOI for the Ethylene fleet significantly. Changing of cargo from ammonia to LPG for several of the LGC vessels increased EEOI. Also higher consumption on some of the vessels due increased marine growth from waiting time in ports and canal inefficiencies.

Six of the LGC will dry dock in 2023. Sale of two older VLGCs during 2021 and 2022 with a relatively high dead weigth/cargo capacity ratio in CBM also contribute to the improvement from 21/22 (18,1/16,5).

Solvang energy consumption and GHG emissions

The total fleet emissions have increased due to the fleet expansion and more operations per vessel. In 2009 we operated 16 vessels and in December 2022 we had 23.

The average emissions per vessel have decreased by 14.6% (kg fuel/NM). This is in spite of a 18.6% increase in cargo capacity. The 18.6% average cargo capacity increase is relevant for the EEOI performance. The 10% increase in DWT % average size is relevant for AER performance above.

Environmental Ship Index (ESI) score 2022

Rating of environmental performance. Best possible score is 100 points. This shows that the five newbuilds on the right side perform very good, around 90 points. All vessels with scrubber technology perform well.

ESI identifies seagoing ships that perform better in reducing air emissions than required by the current emission standards of the International Maritime Organization (IMO)
