Solvang Energy Efficiency Award 2025
Clipper Eirene’s excellent scores gave her a narrow lead this time, just ahead of Clipper Posh in second place, Clipper Eris in third, and Clipper Hermes with a strong fourth-place.
«Clipper Eirene’s excellent scores gave her a narrow lead this time, just ahead of Clipper Posh in second place, Clipper Eris in third, and Clipper Hermes with a strong fourth-place,» says Irene Ringen, Sustainability and
Performance Engineer and Solvang’s head of jury in the Energy Efficiency Award.
The competition rates all Solvang’s vessels and crews by their AER (Annual Efficiency Ratio CO2 per tonne-mile) results – plus their annual SEEMP posters (ship energy efficiency management plan) – and finally the selfevaluation carried out by the crew at year-end.
«We are very impressed by the crews´ awareness of energy efficiency on all vessels. They manage to plan ambitiously yet realistic, to connect AER with operations. Then they make all factors play together to achieve their goals. Truly a crew to be proud of!» Irene Ringen says.
General improvement
In 2025, almost all of Solvang’s vessels went up a notch in the Energy Efficiency Award’s point system, compared to previous years. This means they have achieved better performance in terms of seamanship, operation and proficiency. These are the branches of the competition:
• Route planning
• Weather navigation
• Vessel trim
• Engine operations
• Engine maintenance/performance
• Power management
The point scores
SEEMP
The SEEMP poster is updated annually. Each vessel gets a SEEMP score between 1 and 5, where 5 shows strong efforts and highly relevant plans for each department: Bridge/deck, engine, and galley.
In addition, the crews deliver a selv-assessment report on their own efforts and performance, how the AER was monitored, and what they can improve the next year. They get a score from 1 to 5.
Point scores: AER performance
The official AER value/rating for 2025 is compared to 2024. Additionally, an AER at sea is calculated to compensate for idle time, which is unrelated to the crew performance. Other parameters include fuel consumption per 24 hours for all machineries, vessel speed, time at sea, time in ballast conditions, as well as time since last docking. The results yield a score from 1 to 5.
