Nippon Kaiji Kyokai - ClassNK

Nippon Kaiji Kyokai, also known by the brand name ClassNK or "NK" is a ship classification society. The principal work of ClassNK is to undertake surveys, to ensure that the rules which it has developed are applied to both newbuildings and to existing ships to ensure the safety of the vessels. The rules cover not only hull structures, but also safety equipment, cargo handling gear, engines, machinery, and electrical and electronic systems among others.

By the end of April 2007, the Society had 6,658 ships totaling 146.7 million GT under class. This figure represents approximately 21 percent of the world merchant fleet currently under class. Although based in Japan, where it has 21 service sites, ClassNK has worldwide representation through a extensive global network of 78 exclusive surveyor service sites. ClassNK's surveyors work in shipbuilding and repair yards and at ports across the world, wherever they may be called upon to examine the condition of a ship, so that all of the Society's services are available worldwide. On 15 November 1999, Nippon Kaiji Kyokai celebrated the centenary of its foundation.

ClassNK is one of the seven founding members of the International Association of Classification Societies, otherwise known as IACS. ClassNK is active in the various Working Parties and subcommittees of the organization, and makes major contributions to the realization of the goals of the Association. ClassNK for example played a leading role in the development of the IACS Common Structural Rules, especially for bulk carriers, and is actively supporting the common rule harmonization process.
