What does ABS class notation AMS mean?
AMS is a classification notation that, together with the Maltese
Cross + symbol, indicates that a vessel's machinery, boilers and
systems have been constructed and installed under survey by the
American Bureau of Shipping (ABS) in accordance with the
requirements of the ABS Rules. The + AMS notation is intended for
all new construction of ABS classed self-propelled vessels and
offshore units.
The AMS notation, without the Maltese Cross + symbol, is
assigned to self-propelled vessels and offshore units for which the
machinery, boilers and systems have not been constructed and
installed under survey by the Bureau, but are found satisfactory
with regard to ABS requirements.
