The name change will be effective on 6 March. At the same time, Cal Dive will trade under a new ticker symbol, HELX, on the Nasdaq stock exchange.
However, Cal Dive chairman and chief executive Owen Kratz said in a statement that the name Cal Dive will live on as the title of its shelf services business unit.
He added: "We may then sell a minority stake in it via an initial public offering later this year."
