               Subpart 59.15_Miscellaneous Boiler Repairs
 
Sec. 59.15-10  Bagged or blistered shell plates.

    (a) When the shell plates of cylindrical boilers which are exposed 
to the radiant heat of the fire become bagged or blistered, it shall be 
the duty of the chief engineer in charge of the vessel to notify the 
Officer in Charge, Marine Inspection, for examination before raising 
steam on the boiler.
    (b) Where the shell plate is bagged due to overheating, the Officer 
in Charge, Marine Inspection, may, if in his judgment it is practicable, 
permit the same to be driven back to its original position.
    (c) Where the shell plate has blistered, bagged, or bulged to such 
an extent that there is an appreciable thinning of the plate, the 
Officer in Charge, Marine Inspection, shall require the defective 
portion to be cut away and the shell repaired by fitting a patch of 
steel plate conforming to the requirements of Sec. 52.01-90 of this 
subchapter in place of the defective portion. Care shall be taken that 
the riveting schedule of the patch is so arranged as to give the plate 
sufficient strength to withstand the stress placed on it in service.
