With ships evolving into sophisticated sensor hubs, generating data and connecting through satellites in an expanding interconnected web, DNV GL is adding a new chapter to its rules for ship classification: Digital Features. The new chapter was launched with three new notations (D-INF, DDV, REW) on October 28 and will enter into force on January 1, 2021. In addition, a new Smart vessel notation (Smart)—a framework for assessing and visualizing digital vessel features—was introduced.
