The world's largest OSV owner is looking to get smaller.

On the Houston-based company's fourth quarter conference call Friday, Tidewater chief executive John Rynd said the company was looking to get rid of 40 older ships that are simply too pricey to reactivate as the offshore market continues to lag.

"We remain heavily focused on disposing of these older uncompetitive assets," he said, referring to the ships as increasing liabilities.
