Turning off the deck lights during daylight hours on Navion Saga results in a fuel saving of approximately 30 m3 of diesel per year.

Process to get there: Study to confirm feasibility, as well as evaluation of possible adverse effects to the lifetime expectations of lighting fixtures.

Results (environmental and financial): Reduced CO₂ emissions by 90 tonnes per year, a saving of about 45 000 NOK in taxes as well as reduced diesel fuel costs of 30 000 NOK.

The measure's technical lifetime: The lifetime of the field (1-2 years).
