Vessel’s main boiler (65,000kg/hr evaporation rate) suffered extensive damage to both the furnaces, combustion chamber, tube plates, smoke tubes, both plain and stay tubes, and burner housing assembly due to shortage of water inside the boiler. Both the furnaces and combustion chamber, tube plates and burner housing fabricated in India under Class inspection and transported to china for carrying out fitment in place, welded with 100% radiography and pressure testing to Class satisfaction and approval. Stress relieving was carried out before conducting hydraulic test of the entire boiler.
