ABS class notation ACCU what does it mean?

Answer 1

ACCU indicates that a self-propelled vessel is fitted with various degrees of automation and with remote monitoring and control systems to enable the propulsion machinery space to be periodically unattended and the propulsion control to be effected primarily from the navigation bridge. Where periodically unattended propulsion machinery space is intended, the provisions of class rules (Example ABS Rules for steel vessels, Part 4, Section 4-9-4 ) are to be complied with. Upon verification of compliance, ACCU will be assigned.
