ClassNK is a ship and offshore classification society dedicated to safer, cleaner seas. With some 20% of the world’s merchant fleet on the register, ClassNK is one of the world’s largest classification societies. Based in Japan, ClassNK is a global organization committed to providing the highest quality services to the maritime and offshore industries.
ClassNK is dedicated to ensuring the safety of life and property at sea, and the prevention of pollution of the marine environment. To achieve this mission ClassNK will:
- Focus on delivering the highest quality classification services, by the highest quality personnel, while maintaining its totally independent third party, non-profit status.
- Focus on the development of relevant rules, procedures and guidance, and maintain and develop its commitment to scientific and technological research and development.
- Maintain and develop its global operations in line with the needs of clients using its services.
ClassNK has earned an outstanding reputation for its long-standing dedication to safeguarding life and property at sea and preventing marine pollution through the establishment of universally recognized standards for the design, construction and maintenance of ships and other marine structures.
The principal work of the Society's expert technical staff is to undertake surveys to ensure that the rules which it has developed are applied to newbuildings and existing ships to ensure their safety. The rules cover not only hull structures, but also propulsion systems, electrics, electronic systems, safety equipment, cargo handling gear, and various other areas. ClassNK's surveyors work in shipbuilding and repair yards and at ports across the world, wherever they June be called upon to examine the condition of a ship.
The Head Office is located in Tokyo and in Chiba, Japan, and there are branch offices at the major Japanese and overseas cities throughout the world. As of the end of September 2019, the Society had 9,116 ships totalling over 255 million g.t. under class. This figure represents approximately 20 percent of the world merchant fleet currently under class.
