 +As a result, activity data can fluctuate strongly from year to year. 
 +
 +However, this effect can be explained with the fact that large ocean-going ships do not need to bunker fuels on every single harbour but can go on for weeks without any additional fuel uptake. 
 +
 +This can be further increased with increasing differences in fuel prices.
