Known interferences include, but are not limited to the following: Piping, tubing and gauge line Insulation Salinity sensors and mounting plate Knife switch box NOTE Coast Guard personnel will operate all shipboard machinery and equipment. 3.2 Operational test, initial. Prior to commencement of work, the Contractor must witness Coast Guard personnel perform an initial operational test of all items or shipboard devices to be disturbed, used, repaired, or altered, to demonstrate existing operational condition. The distiller shell cannot be tested because of the leak, but as many components as possible should be tested, as should any other system that is disturbed. Submit a CFR. 3.3 Weld Repair. The Contractor must weld repair a 4” long, horizontal crack in the #2 distilling plant shell in the approximate location shown in Figure 1 through Figure 4 (behind the reinforcement rib). Reference CG Drawing 420-WAGB-531-001 for the arrangement and location of the distilling plant and TP 5171 for the properties of the boiler itself. Section 7 of TP 5171 includes a drawing of the distilling plant and the associated materials. The welding and NDE must be in accordance with SFLC Standard Spec 0740. Submit a CFR with NDE results. 3.4 Hydrostatic test. After all authorized repairs, the Contractor must hydrostatically test the boiler shell in accordance with TP 5171 Paragraph 4.2.1.1 and SFLC Std Spec 0740, Appendix C, Hydrostatic Test. Ensure zero leakage from or permanent deformation of pressure-containing parts by repairing all leaks, deformations, and discrepancies. Submit a CFR. NOTE Coast Guard personnel will operate all shipboard machinery and equipment. 3.5 Operational test, final. Upon completion of work, the Contractor must witness Coast Guard personnel perform an operational test of all items or shipboard devices that were disturbed, used, repaired, or altered, to demonstrate existing operational condition. Even if the distiller shell cannot be tested due to lack of steam, the components that were tested in paragraph 3.2 must be tested again, as should any other systems that were disturbed. Submit a CFR. 3.6 Thermal insulation. In addition to renewing any insulation the Contractor disturbs, the Contractor must also insulate the portion of the distiller where the insulation has been removed – approximately 4 ft x 4 ft – in accordance with Coast Guard Drawing 420-WAGB-508-002, Sheet 32, “Distiller Evaporator Body” and 420-WAGB-508-001.
