About this file
This Task Group Instruction (TGI) details maintenance procedures for the USS Blue Ridge's 1B Boiler Forced Draft Blower (FDB) Shutters. The document specifies cleaning and adjustment work for two FDB shutters manufactured by Bath Iron Works Corporation, each measuring 23.25-inches long by 30.00-inches wide. The maintenance is scheduled for contractor work between 7/21/2026 and 11/21/2027, with the task originating from a Boiler Inspection and Repair Management Information System (BIRMIS) report dated 17 OCT 2024.
The procedure involves disconnecting and reconnecting spring hanger assemblies, removing and reinstalling FDB shutters, cleaning components, and performing adjustments per specified assembly and balancing procedures. SRF-JRMC will provide government-furnished materials and support services, including crane and rigging, utility services, safety inspections, and quality assurance inspections. The work requires multiple trades, including boiler room hours, welding, painting, and installation personnel. Potential hazards include asbestos and lead, and the material list includes items such as silicone grease, insulation sleeves, packing, adhesives, and insulation cement.
