Class Notation
This notation was available for unrestricted service large vessels, greater than 90 meters in length,
whose signed contracts were made between owners and shipbuilder until 31 December 1999. After
this date, the ABCU notation was terminated for new construction of these large vessels whose
automation system arrangements are primarily in accordance with the ACCU requirements.
