3.3 Insulation treatment. The Contractor shall touch up thin and bare spots on the cleaned windings with an air drying varnish in accordance with SFLC Std Spec 3100, 3.3.2, Insulation treatment.

3.4 Utility services. The use of Coast Guard utility services, both afloat and ashore, for performance of this work item is restricted as follows:

13 (Draft-00)

3.4.1 Electrical power. Electrical power for temporary tools and equipment used to accomplish this work item shall comply with SFLC Std Spec 0450. When no other power source options are practicable, such loads may be energized from a temporary generator located afloat or ashore in accordance with Appendix E of SFLC Std Spec 0450.

3.4.1.1 Dockside equipment. Power solely for dockside tools and equipment may be taken from the dockside electrical power distribution system in accordance with Appendix A (preferred) of SFLC Std Spec 0450 or from the shipboard electrical power distribution system in accordance with Appendix D of SFLC Std Spec 0450.

3.4.1.2 Shipboard equipment. Power solely for shipboard tools and equipment may be taken from the ship service electrical distribution system in accordance with Appendix B (preferred) of SFLC Std Spec 0450 or from the dockside electrical power distribution system in accordance with Appendix C of SFLC Std Spec 0450.

4. NOTES

4.1 Conditional performance. This work item is performed only when warranted by the condition of the generator windings. The mere presence of dust is not sufficient justification to perform this work item.

4.1.1 Note that there is some risk that solutions used during the cleaning process may penetrate through microscopic cracks in the varnish, carrying contaminants deeper into the windings through capillary

14 (Draft-00) action. Once so embedded, such contamination cannot be removed and insulation resistance could actually be degraded such that a costly and time consuming rewind would be necessary.

4.1.2 Cleaning is normally only warranted when the windings have been wetted by sea water or insulation resistance trends suggest that the machine will fall below the minimum acceptable insulation resistance for operation before the next depot level availability.

4.2 Shop cleaning. This generator is (rotor only) removable from the vessel without making a hull cut.

See CG Drawing 225B-WLB 201-2 for rigging path to weather including any bolted (BERP) or welded (WERP) equipment removal plates that must be removed. For machines that can be removed from the vessel through existing accesses or openings created by other work items, it is generally quicker and more cost effective to offload the affected generator from the vessel and perform the work ashore in a generator repair shop. Such tasking should be performed under “Ship Service Diesel Generator, Overhaul” and not this work item.

3. REQUIREMENTS

3.1 General. Inspect, recondition, and test in place the windings of the Thruster Generator in accordance with SFLC Std Spec 3100. Generator data is shown in Table 1 below.

3.1.1 CIR. Submit a CIR for the inspections listed in the following paragraph(s):

None.

3.1.2 Tech Rep. Provide the services of a Technical Representative (Tech Rep), who is familiar with AC synchronous machines and shall be present during the performance of this work. The technical representative shall be employed by a shop that is a member of the Electrical Apparatus Service Association (EASA) and that shop shall adhere to the association’s standards, including ANSI/EASA

3.1.3 Protective measures. Furnish and install all protective coverings to seal off and protect all non-affected vessel's components, equipment, and spaces in the vicinity of the work area against contamination during the performance of work. Upon completion of work, remove all installed protective measures, inspect for the presence of contamination, and return all contaminated equipment, components, and spaces to original condition of cleanliness.

3.1.4 Interferences. Handle all interferences in accordance with SFLC Std Spec 0000, paragraph 3.3.5 (Interferences).

3.2 Optional work. Perform the optional work sections of SFLC Std Spec 3100 as follows:

3.2.1 Bearing wear. Measure and record bearing wear in accordance with SFLC Std Spec 3100, Section 3.2.3.6.

3.2.2 Collector rings. As this machine is a brushless design, do not measure and record collector ring wear and concentricity in accordance with SFLC Std Spec 3100, Section 3.2.3.7.

3.2.3 Rotor extraction. Remove the rotor for cleaning within the compartment in accordance with SFLC Std Spec 3100, Section 3.2.3.8, Rotor removal. Reinstall it afterwards.

3.2.4 Installed prime mover. During drying operations, the installed prime mover (e.g., engine or barring gear) may not be used to spin the rotor while circulating current through the field windings.

3.3 Utility services. The use of Coast Guard utility services, both afloat and ashore, for performance of this work item is restricted as follows:

3.3.1 Electrical power. Electrical power for temporary tools and equipment used to accomplish this work item shall comply with SFLC Std Spec 0450. When no other power source options are practicable, such loads may be energized from a temporary generator located afloat or ashore in accordance with Appendix E of SFLC Std Spec 0450.

3.3.1.1 Dockside equipment. Power solely for dockside tools and equipment may be taken from the dockside electrical power distribution system in accordance with Appendix A (preferred) of SFLC Std Spec 0450 or from the shipboard electrical power distribution system in accordance with Appendix D of SFLC Std Spec 0450.

3.3.1.2 Shipboard equipment. Power solely for shipboard tools and equipment may be taken from the ship service electrical distribution system in accordance with Appendix B (preferred) of SFLC Std Spec

17 (Draft-00)

0450 or from the dockside electrical power distribution system in accordance with Appendix C of SFLC Std Spec 0450.

3.3.2 Potable water. Hot and cold potable water may be obtained from shipboard systems. Cold potable water may be obtained from dockside connections.

3.3.3 Compressed air. Compressed air for tools and generator hand cleaning may be taken from the ship service air system. Air that is to be blown into a generator shall be filtered for particulate, water, and oil prior to discharge.

3.4 External heating. External heat must be applied following cleaning to dry out the windings. The heater power rating will vary with the amount of equipment to be dried, degree of enclosure, and amount of ventilation. The estimate in Table 2 below assumes that no heat is lost by radiation or by forced or natural convection; consequently, the input power rating should be increased by a few kilowatts to compensate for heat losses.

3.4.1 Limit heat input so that winding temperatures do not increase more than 7°F per hour.

3.4.2 Do not exceed a winding temperature of 212°F.
