PART 59_REPAIRS TO BOILERS, PRESSURE VESSELS AND APPURTENANCES--Table of Contents
 
Subpart 59.10_Welding Repairs to Boilers and Pressure Vessels in Service
 
Sec. 59.10-1  Scope.


    (a) Repairs to boilers or pressure vessels in service may be 
performed by welding provided the welding meets the applicable 
requirements of part 57 of this subchapter.
    (b) No repairs by welding shall be made except temporary emergency 
repairs without prior approval of the Officer in Charge, Marine 
Inspection. Emergency repairs shall be replaced with permanent repairs 
meeting the requirements of this subchapter when the vessel returns to a 
port in which an Officer in Charge, Marine Inspection, is located except 
in the case of minor repairs which in the opinion of the Officer in 
Charge, Marine Inspection, do not materially affect the safety of the 
boiler or pressure vessel.
    (c) Repair welding of power boilers, not meeting the requirements of 
subpart 52.05 of this subchapter, is prohibited unless the stress is 
carried by such other type(s) of construction complying with the 
requirements of this subchapter, and where the adequacy of the boiler 
design is not solely dependent upon the strength of the welds.
    (d) Only welded repairs as specified in this subchapter are 
permitted on boilers and pressure vessels. The welding repairs allowed 
by this subpart apply only to boilers and pressure vessels fabricated of 
carbon steel. Welding repairs to boilers and pressure vessels fabricated 
of alloy steel will be given special consideration by the Commandant. 
Such other method of repairs by means of welding not covered in this 
subchapter shall be referred to the Commandant and may be authorized by 
him, if in his opinion, it meets the intent of this subchapter.
