The process of determining premium rates for fleets. Different techniques will be used for the individual risks in a fleet, largely based on the size of the fleet and the amount of claims history available. For example, while small fleets may be largely rated according to book rates per vehicle with some adjustment for expense savings, some form of experience rating will be used for larger fleets with the credibility increasing with the size of the fleet. In Marine Hull Insurance, fleet rating will aim to incorporate the characteristics of a fleet (for example ones under common management) into the rating process, as well as the risk characteristics of the individual ship. Advanced statistical rating techniques could be applied although simpler rating techniques are used in practice.
