The purpose of the study was to better understand the variability in fuel efficiency of a Norwegian freeze trawler targeting cod, haddock, saithe and shrimps. Additional goals were to evaluate whether batch is actually a relevant resolution in LCAs and to increase the knowledge about the reasons behind variability. This was done by collecting daily data on fuel use and production for two years. Fishing trips targeting shrimps were shown to be significantly more fuel intensive than those targeting fish such as cod, haddock and saithe. Other actors explaining the difference between fishing trips were distance from port to fishing location, season, weather. Results can be used for internal improvement and as a basis for a simplified tool for environmental assessment.
