DNV has developed rules and standards for ships for more than 140 years, and is a world leading classification society. We also develop rules and standards for the offshore industry, particularly within oil- and gas field development, production and transportation. You can access our rules and standards through the DNV webshop and our extranet DNV Exchange.
