The "Digital twin". Digitization process from the point of view of a classification society
The process of digitalization in our society is undeniable and unstoppable and ships are adapting more and more to this new environment. This offers great advantages, since ships can send/receive all the information on all aspects of their current status (allowing more efficient management during the ship's life and even opening the door to autonomous navigation), but this presents a number of intrinsic difficulties due to their connected state (cybersecurity). All the above will be developed with a massive sensorization of the ships, which will indicate their condition, going from a reactive maintenance to a predictive maintenance. This requires the figure of the digital twin, which digitally represents the physical reality of the ship, and which will be a single source of information for all actors.
This digital twin opens the door to "Digital Classification" by Bureau Veritas, in which traditional 2D plans are no longer necessary, but work is done directly in 3D on the Digital Twin. Bureau Veritas, as a reference classification society, has adapted to the current situation of the industry, favoring the digitalization process in all its aspects.
The objective of this article is to present the current state and foreseeable evolution of the technology leading to the Digital Twin concept, its implications in the design and maintenance of ships, all from the point of view of a Classification Society while exemplifying the digitalization process of a Classification Society in different aspects.
