Genova-based classification society RINA has introduced new voluntary standards which will allow ships to connect to shore-based electricity while in port, reducing harbour air pollution. And at the same session of its Technical Committee it approved a series of new standards aimed at improving security standards for yachts. The new notation HVSC - High Voltage Shore Connection - sets standards to design into a newbuilding or modify an existing ship so that electricity can be supplied from the shore to the ship for the operation of the ship's machinery while in port. The diesel generators can be shut down, considerably reducing the ship's emissions.
