Abstract: Ice abrasion is a severe degradation mechanism responsible for reduced service life of concrete offshore structures in areas with ice drift. A research program within the COncrete INnovat ion centre (COIN) is current ly in progress on development of a model for estimation of expected ice abrasion rates. As a part of the program an accelerated ice abrasion test rig is developed. The concept is to calibrate the test rig against real in situ measurements from long term field exposed concrete offshore structures with known ice abrasion. As a part of this work, some earlier published ice abrasion models have been reviewed. For comparison purposes these models are presented herein for a standard set of input parameters. In situ measurements from the Finnish lighthouses Oulu 2,3 and Raahe in the Gulf o f Bothnia are used to evaluate the different models ability to predict long term ice abrasion depths.
