That logo belongs to Ocean Players Club, which is the entity that operates the casinos of all the Carnival Cruise Lines, Inc. ships.

I do not know if Carnival owns them, but they are a separate business entity. Here is a link to their web-site:

They manage the on-board casinos of Carnival, Holland America, Cunard, and Costa Crocerie, which are all owned by Carnival.
