Remote Inspection Techniques (RIT) in Maritime Industry

Regulations


Remote Inspection Techniques (RIT) offer a survey method that allows the examination of various structure parts without requiring direct physical access by the surveyor. With the development of remote inspection techniques (RITs), such as remotely operated vehicles (ROVs) and real-time sensors which are carried by drones, the maritime industry is increasingly applying remote inspection techniques (RITs).
