This data set contains the Risk Index Values in Table 1.3 of the
2169+
International Maritime Organization rules within the Polar Operational
2170+
Limit Assessment Risk Indexing System (POLARIS). The basis of POLARIS is
2171+
an evaluation of the risks posed to the ship by ice conditions in relation

to the ship's assigned ice class.
