Classification is a system for safeguarding life, property and the environment at sea. It entails verification against a set of requirements during design, construction and operation of ships and offshore units. These requirements are based on the accumulated experience from DNV’s large classed fleet, research and development and almost 140 years of experience. Our surveyors stationed around the world work with customers to ensure compliance throughout the lifetime of the classified object. DNV is one of the world’s leading classification societies, and has worked to improve safety at sea since 1864.
