ClassNK

Founded in 1899, ClassNK is an independent third party certification body offering a variety of services, such as ship surveys, to help ensure the safety of the ocean and preservation of the environment. Through its 120 years of history as a classification society, ClassNK has established technical rules for ships, conducted plan approvals and surveys on hulls, equipment, and materials for individual ships based on the rules, and classified ships satisfying standards. It has roughly 260 million gross tons or some 20% of the world's merchant fleet on its register. The Society is authorized to carry out surveys and certifications on behalf of over 100 flag states based on international conventions and regional regulations on safety, environmental pollution prevention, security, and the labor environment. Utilizing its knowledge and experience cultivated as a third-party certification body over many years, the Society provides many certification services for management systems such as quality, environment, occupational health and safety based on ISO standards, and renewable energy including wind power generation to contribute to economic and social development through a network of over 130 exclusive surveyor offices across the world.
