Manufacture
During manufacture welded joints
are inspected using X-ray, Flaw Detectors or Phased
array systems to ensure that they are defect-free.
Similar techniques are used to inspect key components
such as, boilers, shafts and propellers.
Aluminium hulled vessels generally are built for
minimum weight, so have a controlled thickness.
Thickness meters are used to ensure that the thickness
of plating is adequate, especially where welds have
been dressed by grinding.
In-service inspection
Sea going vessels are generally subject to regular
inspections of which NDT can form an important part:
Thickness surveys are carried out, Using Thickness
meters or Flaw Detectors, to ensure that there is
no dangerous corrosion on hull plating or other
critical regions.
The Soundscan equipment is used for checking the
integrity of seals and joints on hatches, bulkheads,
cable runs etc. as in other industries, It can also
assist with inspection of motors, compressed air
systems, electrical systems etc.
