Most likely ship after Oder/1870?

My ancestor, Mikkel Haugerud (and family) left Christinia on April 15, 1870 on the Oder headed for Hull or London. According to this web site, the agent of Wilson line would be H. Heitman & Son. Is it possible to determine which ship and line would be most likely from Liverpool or London? I assume the trip from Norway to USA took about 2 weeks. I have not found him in NY micofilm of arriving vessels. Thanks. Jon
