| 1. A device for measuring a thickness of a vessel steel plate comprising:
a first traveling carriage having a steering mechanism that can change a radius of curvature of traveling track, and capable
of traveling on a steel plate of a vessel mirror part formed by a curved surface having a predetermined curvature and a circular
projection form;
a second traveling carriage having a magnetic material mounted thereon for exerting an attraction force on the vessel steel
plate and a traveling driving mechanism that can move left and right of the carriage forward or backward, independently, and
capable of traveling on a steel plate of a vessel barrel part substantially in a cylindrical form that continues in a direction
substantially perpendicular to the vessel mirror part; and
an ultrasonic probe unit on which a plurality of ultrasonic probes are mounted, and
the device having attaching and detaching means for selectively attaching the ultrasonic probe unit to or detaching the unit
from the first traveling carriage and the second traveling carriage.
