In the midship area, radiographies are to be taken at
the joinings of panels.
Each radiography is situated in a butt joint at a cross-shaped
welding.
In a given ship cross-section bounded by the panels, a radiography is to be made of each butt of sheerstrake, stringer,
bilge and keel plate; in addition, the following radiographies are to be taken:
• bottom plating: two
• deck plating: two
• side shell plating: two each side.
For ships where B + D ≤ 15 m, only one radiography for
each of the above items is required.
This requirement remains applicable where panel butts are
shifted or where some strakes are built independently from
the panels. It is recommended to take most of these radiographies at the intersections of butt and panel seams.
Still in the midship area, radiographic testing is to be carried
out, at random, of the following main members of the structure:
• butts of continuous longitudinal bulkheads
• butts of longitudinal stiffeners, deck and bottom girders
contributing to the overall strength
• assembly joints of insert plates at the corners of the
openings.
Moreover, radiographic testing is to be carried out, at random, of the weldings of the bilge keel and of intermediate
flat.
