Overview of ClassNK Archive Center

A shipyard, as the intellectual property (IP) holder, is requried to provide a Ship Construction File (SCF), which contains structural drawings based upon design and construction information, to a shipowner. As the party responsible for the storage of such information, the shipowner is then required provide means for safely and securely storing said information on board concerned ships throughout their operational lifetimes. Since this information includes highly-sensitive intellectual property matters related to shipbuilders, storage in a shore-based secure archive center is permitted.

ClassNK Archive Center assumes the role of such a shore-based archive center and provides high-level protection for the intellectual property found in SCFs using encryption measures such as obfuscation, etc.; moreover, the center stores SCF drawings (including those for ships registered to other classification societies) in a secure cloud-based platform for the entire life of the ship, and is capable of providing immediate support 24 hours a day in the case of an emergency, such as an accident at sea .
In addition to services provided by a shore-based archive center, the ClassNK Archive Center has also been providing a platform-based service for all vessel types since 2013 to not only further increase ease of use, but to also contribute to the overall unification of document storage and management.
