DESCRIPTION:Ice action on offshore structures and ships is des
 cribed commonly by the so-called pressure-area rel
 ationship. This describes the average ice contact 
 pressure on a prescribed area\, pressure that is a
 ssumed to be uniform. Several reasons for this emp
 irical observation have been proposed\; non-simult
 aneous failure of ice\, size effect in strength (W
 eibull effect) and a specific pressure distributio
 n. These are described and reviewed in the present
 ation. Further the pressure-area relationship has 
 been used both in describing the design i.e. maxim
 um forces and also in describing the forces during
  ice indentation in a contact situation. Is the sa
 me relationship applicable in both cases? Finally 
 there is not a clear agreement on how to use the r
 elationship in design. Some suggestions for this a
 re given.
