One of the things that you can do is look into the history of Ice Seamanship, which is both fascinating and almost completely un-researched.
Here are a couple of modern ones which may well have insights:
Ice seamanship / by George Q. Parnell.

Handling ships in ice : a practical guide to handling class 1A and 1AS ships / by Johan Buyssse [i.e. Buysse].

Polar ship operations : a practical guide / by Duke Snider.

And an older one:
