Classification societies are organizations that establish and maintain technical standards for the construction and maintenance of ships and marine structures. They assess the design, materials, and workmanship of vessels to ensure they meet safety and performance criteria. These societies also conduct regular inspections and surveys to verify compliance with their standards. Additionally, classification societies play a crucial role in the maritime industry by providing certification services. This certification is often required for ships to obtain insurance and to comply with international regulations. Notable examples of classification societies include Lloyd's Register, DNV GL, and American Bureau of Shipping.
