Benchmarking: The EETA compares the energy efficiency of specific vessels with the relevant peer group of the entire world’s fleet in the respective segment, intake, age, etc., based on technical details and common operating profiles. The profiles, gradually differentiated by vessel size, reflect today’s slow steaming practice.
Efficiency improvement: In addition to the assessment of the vessel as is, improvement potential from the application of energy efficiency retrofitting measures is assessed. For a first outside-in cost–benefit assessment of energy saving potential and retrofitting costs of seven common, distinct and detailed retrofitting measures are considered. The measures include bow retrofit, propeller optimization, the installation of propulsion improvement devices, main engine part load optimization, the installation of a frequency-controlled shaft generator, auxiliary system optimization and capacity enhancement. Some measures can favourably be combined, others mutually exclude each other. The best suitable combination is chosen.
Versatility: The EETA is used frequently by ship owners, charterers, ship managers, ship financing banks, brokers and others, for instance, to:
- Market a vessel’s favourability to charterers and buyers
- Check how a vessel is looked at for charter or purchase compared to peers
